What is AJP connector in Tomcat?

AJP connectors

Apache JServ Protocol, or AJP, is an optimized binary version of HTTP that is typically used to allow Tomcat to communicate with an Apache web server.

How do I enable AJP?

To enable the AJP connector and run it on port 8009 (default), perform the following steps:
  1. Open the /Apache Software Foundation/Tomcat 9.0_Tomcat9_30/conf/server. …
  2. Remove the comments for the connector.
  3. Modify the address parameter to expand the listening range to not only the loopback address.

What is AJP connector Tomcat 9?

The AJP Connector element represents a Connector component that communicates with a web connector via the AJP protocol.

How do I disable AJP protocol port?

Process
  1. Open the file that controls the AJP configuration in a text editor. $CONTRAST_HOME/data/conf/server.properties.
  2. Edit the the AJP settings to set enabled.ajp to false ajp.enabled=true ajp.port=8009.
  3. Save the file.
  4. Restart your TeamServer.

What is AJP packet?

An AJP flush message is a SEND_BODY_CHUNK packet with no body content. Proxy implementations like mod_jk or mod_proxy_ajp will flush the data buffered in the web server to the client when they receive such a packet. Setting this to false can reduce AJP packet traffic but might delay sending packets to the client.

What is proxy AJP?

mod_proxy_ajp is an Apache module which can be used to forward a client HTTP request to an internal Tomcat application server using the AJP protocol […] mod_proxy_ajp is an Apache module which can be used to forward a client HTTP request to an internal Tomcat application server using the AJP protocol.

What is AJP protocol used for?

Apache JServ Protocol (AJP) is used for communication between Tomcat and Apache web server. This protocol is binary and is enabled by default. Anytime the web server is started, AJP protocol is started on port 8009. It is primarily used as a reverse proxy to communicate with application servers.

What is connector in server XML?

Introduction. The HTTP Connector element represents a Connector component that supports the HTTP/1.1 protocol. It enables Catalina to function as a stand-alone web server, in addition to its ability to execute servlets and JSP pages.

Is Ajp secure?

EDIT: AJP is not designed to be secure, if you need security, use mod_proxy_http and proxy over https, or create SSH tunnel. Needless to say, you will have to pay for this overhead.

Can Tomcat run on port 443?

Tomcat can be configured to listen on SSL Port 443. Then you could turn off the SSL listener in the Apache Web server and use only Tomcat to handle your SSL connections. You can modify the Tomcat configuration by editing the file named “server. xml” in the Tomcat conf directory.

Where is Catalina SH Tomcat 9?

CATALINA_HOME is the folder where Apache Tomcat is installed e.g. c:\program files\Apache Tomcat or /usr/apache/tomcat . It is the folder where you unzip Tomcat in the first place (when you install from zip).

How does Tomcat NIO connector work?

The NIO connector (non-blocking I/O) is a bit more complicated. It uses the java NIO library and multiplexes between requests. It has two thread pools – one holds the the poller threads, which handle all incoming requests and push these requests to be handled by worker threads, held in another pool.

What is AJP listener?

The AJP listeners are child resources of the subsystem undertow. They are used with mod_jk, mod_proxy and mod_cluster of the Apache httpd front-end.

What is mod_jk and Mod_proxy?

mod_jk is mature, stable and extremely flexible. It is under active development by members of the Tomcat community. mod_proxy_ajp is distributed with Apache httpd 2.2 and later. Note that the communication protocol used is AJP. mod_proxy_http is a cheap way to proxy without the hassles of configuring JK.

Is AJP secure?

EDIT: AJP is not designed to be secure, if you need security, use mod_proxy_http and proxy over https, or create SSH tunnel. Needless to say, you will have to pay for this overhead.

What is server shutdown port in Tomcat?

Tomcat listens on TCP port 8005 to accept shutdown requests. By connecting to this port and sending the SHUTDOWN command, all applications within Tomcat are halted.

Tomcat not starting (throwing java.net.BindException: )

I have done the following settings to run a Java web project but somehow my Tomcat is not starting from Eclipse:

JAVA_HOME : C:\Program Files\Java\jdk1.6.0_03 PATH : C:\Program Files\Java\jdk1.6.0_03\bin CATALINA_HOME : D:\javaworkspaces\apache-tomcat-7.0.27

Then as is required, I set up a new server from Eclipse and give the Tomcat installation path.

As advised in some forums, I have added tomcat-juli.jar to the class path.

In spite of all this when I try starting the Tomcat Server, I get the the error as tomcat not staring in 45 sec.

I get the following log message:

Understanding Tomcat connectors

Connector elements are Tomcat’s links to the outside world, allowing Catalina to receive requests, pass them to the correct web application, and send back the results through the Connector as dynamically generated content.

In this article, we’ll learn how Tomcat uses Connectors in its element hierarchy, take a look at some basic syntax for configuring Connectors, and explain the uses of Tomcat’s two Connector types: HTTP and AJP.

How a connector works

Each Connector element represents a port that Tomcat will listen to for requests. By arranging these Connector elements within hierarchies of Services and Engines, a Tomcat administrator is able to create a logical infrastructure for data to flow in and out of their site. In addition to routing user-generated requests to the appropriate Services, connectors can also be used to link Tomcat to other supporting web technologies, such as an Apache web server, to efficiently balance the load of work across the network.

The Connector element only has one job – listening for requests, passing them on to an Engine, and returning the results to its specified port.

On its own, the Connector can’t function – the only information this element contains is a port to listen on and talk to, and some attributes that tell it exactly how to listen and talk.

Information about what Server the specified port is located on, what Service the connector is a part of, and what Engine connections should be passed to is provided to the Connector by its location Tomcat’s nested element hierarchy.

Tip: Tcat’s live diagnostic feeds gives you fast, centralized insight into Connector performance across your entire Tomcat infrastructure. Download Tcat now.

Nesting connector elements

To learn how to nest an Connector to achieve the functionality you need, let’s look at a simplified Tomcat server configuration:

There are two Connector elements here, listening for connections on ports 8443 and 8444. It is important to note that an OS will only allow one connector on each port, so every connector you define will require its own unique port.

As you can see, both Connector elements are nested inside a single generic Service element, which is in turn contained within a single Server. This arrangement tells the Connectors to listen to their specified ports on their containing server, and to pass any connections only to the Engine belonging to their containing Service, which will process the requests and pass the results back to the Connectors.

Using the current arrangement, both Connectors will pass all requests to the same Engine, which will in turn pass all these requests to both of its contained web applications. This means that each request will potentially generate two responses, one from each application.

Now let’s assume that we want to change this configuration, so that instead of receiving two responses for every request received by either Connector, we want each Connector to pass requests from its port only to one specific web application. To achieve this functionality, we simply need to rearrange the element hierarchy so that it resembles something like this:

Great! Now we have two different Services, with two different Connectors, passing connections from two different ports on the same Server to two different Engines for processing. Although obviously more complicated in real-world situations, all Tomcat Connector-related configuration builds upon these simple rules of element hierarchy.

Types of connectors

There are two basic Connector types available in Tomcat – HTTP and AJP. Here’s some information about how they differ from one another, and situations in which you might use them.

HTTP connectors

Although Tomcat was primarily designed as a servlet container, part of what makes it so powerful is Catalina’s ability to function as a stand-alone web server. This functionality is made possible by the HTTP Connector element.

This Connector element, which supports the HTTP/1.1 protocol, represents a single Connector component listening to a specific TCP port on a given Server for connections.

The HTTP Connector has many attributes that can be modified to specify exactly how it functions, and access functions such as proxy forwarding and redirects.

Two of the most important attributes of this Connector are the “protocol” and “SSLEnabled” attributes.

The “protocol” attribute, which defines the protocol the Connector will use to communicate, is set by default to HTTP/1.1, but can be modified to allow access to more specialized protocols. For example, if you wanted to expose the connectors low level socket properties for fine tuning, you could use the “protocol” attribute to enable the NIO protocol. Setting the “SSLEnabled” attribute to “true” causes the connector to use SSL handshake/encryption/decryption.

HTTP connectors can also be used as part of a load balancing scheme, in conjunction with an HTTP load balancer that supports session stickiness, such as mod_proxy. However, as AJP tends to handle proxying better than HTTP, this usage is not common.

For an exhaustive overview of HTTP Connector attributes, consult the most recent Apache Tomcat Documentation site.

AJP connectors

AJP Connectors work in the same way as HTTP Connectors, but they use the AJP protocol in place of HTTP. Apache JServ Protocol, or AJP, is an optimized binary version of HTTP that is typically used to allow Tomcat to communicate with an Apache web server. AJP Connectors are most commonly implemented in Tomcat through the plug-in technology mod_jk, a re-write of the defunct mod_jserv plug-in with extensive optimization, support for more protocols through the jk library, and Tomcat-specific functionality. The mod_jk binaries and extensive documentation are available on the Tomcat Connector project website.

This functionality is typically required in a high-traffic production situation, where Tomcat clusters are being run behind an Apache web server.

This allows the Apache server to deliver static content and proxy requests in order to balance request loads effectively across the network and let the Tomcat servers focus on delivering dynamic content.

Want to learn more? There are many detailed articles about fronting Tomcat with Apache, load balancing, and other AJP Connector related subjects available on Apache’s Tomcat documentation site.

Apache Tomcat 9 Configuration Reference (9.0.65)

To use AJP, you must specify the protocol attribute (see above).

The standard AJP connectors (NIO, NIO2 and APR/native) all support the following attributes in addition to the common Connector attributes listed above.

Attribute Description

acceptCount The maximum length of the operating system provided queue for incoming connection requests when maxConnections has been reached. The operating system may ignore this setting and use a different size for the queue. When this queue is full, the operating system may actively refuse additional connections or those connections may time out. The default value is 100.

acceptorThreadCount The number of threads to be used to accept connections. Increase this value on a multi CPU machine, although you would never really need more than 2 . Also, with a lot of non keep alive connections, you might want to increase this value as well. Default value is 1 .

acceptorThreadPriority The priority of the acceptor threads. The threads used to accept new connections. The default value is 5 (the value of the java.lang.Thread.NORM_PRIORITY constant). See the JavaDoc for the java.lang.Thread class for more details on what this priority means.

address For servers with more than one IP address, this attribute specifies which address will be used for listening on the specified port. By default, the connector will listen on the loopback address. Unless the JVM is configured otherwise using system properties, the Java based connectors (NIO, NIO2) will listen on both IPv4 and IPv6 addresses when configured with either 0.0.0.0 or :: . The APR/native connector will only listen on IPv4 addresses if configured with 0.0.0.0 and will listen on IPv6 addresses (and optionally IPv4 addresses depending on the setting of ipv6v6only) if configured with :: .

ajpFlush A boolean value which can be used to enable or disable sending AJP flush messages to the fronting proxy whenever an explicit flush happens. The default value is true .

An AJP flush message is a SEND_BODY_CHUNK packet with no body content. Proxy implementations like mod_jk or mod_proxy_ajp will flush the data buffered in the web server to the client when they receive such a packet. Setting this to false can reduce AJP packet traffic but might delay sending packets to the client. At the end of the response, AJP does always flush to the client.

allowedRequestAttributesPattern The AJP protocol passes some information from the reverse proxy to the AJP connector using request attributes. These attributes are: javax.servlet.request.cipher_suite

javax.servlet.request.key_size

javax.servlet.request.ssl_session

javax.servlet.request.X509Certificate

AJP_LOCAL_ADDR

AJP_REMOTE_PORT

AJP_SSL_PROTOCOL

JK_LB_ACTIVATION

CERT_ISSUER (IIS only)

CERT_SUBJECT (IIS only)

CERT_COOKIE (IIS only)

HTTPS_SERVER_SUBJECT (IIS only)

CERT_FLAGS (IIS only)

HTTPS_SECRETKEYSIZE (IIS only)

CERT_SERIALNUMBER (IIS only)

HTTPS_SERVER_ISSUER (IIS only)

HTTPS_KEYSIZE (IIS only) The AJP protocol supports the passing of arbitrary request attributes. Requests containing arbitrary request attributes will be rejected with a 403 response unless the entire attribute name matches this regular expression. If not specified, the default value is null .

bindOnInit Controls when the socket used by the connector is bound. By default it is bound when the connector is initiated and unbound when the connector is destroyed. If set to false , the socket will be bound when the connector is started and unbound when it is stopped.

clientCertProvider When client certificate information is presented in a form other than instances of java.security.cert.X509Certificate it needs to be converted before it can be used and this property controls which JSSE provider is used to perform the conversion. For example it is used with the AJP connectors, the HTTP APR connector and with the org.apache.catalina.valves.SSLValve.If not specified, the default provider will be used.

connectionLinger The number of seconds during which the sockets used by this Connector will linger when they are closed. The default value is -1 which disables socket linger.

connectionTimeout The number of milliseconds this Connector will wait, after accepting a connection, for the request URI line to be presented. The default value for AJP protocol connectors is -1 (i.e. infinite).

executor A reference to the name in an Executor element. If this attribute is set, and the named executor exists, the connector will use the executor, and all the other thread attributes will be ignored. Note that if a shared executor is not specified for a connector then the connector will use a private, internal executor to provide the thread pool.

executorTerminationTimeoutMillis The time that the private internal executor will wait for request processing threads to terminate before continuing with the process of stopping the connector. If not set, the default is 5000 (5 seconds).

keepAliveTimeout The number of milliseconds this Connector will wait for another AJP request before closing the connection. The default value is to use the value that has been set for the connectionTimeout attribute.

maxConnections The maximum number of connections that the server will accept and process at any given time. When this number has been reached, the server will accept, but not process, one further connection. This additional connection be blocked until the number of connections being processed falls below maxConnections at which point the server will start accepting and processing new connections again. Note that once the limit has been reached, the operating system may still accept connections based on the acceptCount setting. The default value is 8192 . For NIO/NIO2 only, setting the value to -1, will disable the maxConnections feature and connections will not be counted.

maxHeaderCount The maximum number of headers in a request that are allowed by the container. A request that contains more headers than the specified limit will be rejected. A value of less than 0 means no limit. If not specified, a default of 100 is used.

maxThreads The maximum number of request processing threads to be created by this Connector, which therefore determines the maximum number of simultaneous requests that can be handled. If not specified, this attribute is set to 200. If an executor is associated with this connector, this attribute is ignored as the connector will execute tasks using the executor rather than an internal thread pool. Note that if an executor is configured any value set for this attribute will be recorded correctly but it will be reported (e.g. via JMX) as -1 to make clear that it is not used.

minSpareThreads The minimum number of threads always kept running. This includes both active and idle threads. If not specified, the default of 10 is used. If an executor is associated with this connector, this attribute is ignored as the connector will execute tasks using the executor rather than an internal thread pool. Note that if an executor is configured any value set for this attribute will be recorded correctly but it will be reported (e.g. via JMX) as -1 to make clear that it is not used.

packetSize This attribute sets the maximum AJP packet size in Bytes. The maximum value is 65536. It should be the same as the max_packet_size directive configured for mod_jk. Normally it is not necessary to change the maximum packet size. Problems with the default value have been reported when sending certificates or certificate chains. The default value is 8192. If set to less than 8192 then the setting will ignored and the default value of 8192 used.

processorCache The protocol handler caches Processor objects to speed up performance. This setting dictates how many of these objects get cached. -1 means unlimited, default is 200 . If not using Servlet 3.0 asynchronous processing, a good default is to use the same as the maxThreads setting. If using Servlet 3.0 asynchronous processing, a good default is to use the larger of maxThreads and the maximum number of expected concurrent requests (synchronous and asynchronous).

secret Only requests from workers with this secret keyword will be accepted. The default value is null . This attribute must be specified with a non-null, non-zero length value unless secretRequired is explicitly configured to be false . If this attribute is configured with a non-null, non-zero length value then the workers must provide a matching value else the request will be rejected irrespective of the setting of secretRequired.

secretRequired If this attribute is true , the AJP Connector will only start if the secret attribute is configured with a non-null, non-zero length value. This attribute only controls whether the secret attribute is required to be specified for the AJP Connector to start. It does not control whether workers are required to provide the secret. The default value is true . This attribute should only be set to false when the Connector is used on a trusted network.

tcpNoDelay If set to true , the TCP_NO_DELAY option will be set on the server socket, which improves performance under most circumstances. This is set to true by default.

threadPriority The priority of the request processing threads within the JVM. The default value is 5 (the value of the java.lang.Thread.NORM_PRIORITY constant). See the JavaDoc for the java.lang.Thread class for more details on what this priority means.If an executor is associated with this connector, this attribute is ignored as the connector will execute tasks using the executor rather than an internal thread pool. Note that if an executor is configured any value set for this attribute will be recorded correctly but it will be reported (e.g. via JMX) as -1 to make clear that it is not used.

throwOnFailure If the Connector experiences an Exception during a Lifecycle transition should the Exception be rethrown or logged? If not specified, the default of false will be used. Note that the default can be changed by the org.apache.catalina.startup.EXIT_ON_INIT_FAILURE system property.

tomcatAuthentication If set to true , the authentication will be done in Tomcat. Otherwise, the authenticated principal will be propagated from the native webserver and used for authorization in Tomcat. The web server must send the user principal (username) as a request attribute named REMOTE_USER . Note that this principal will have no roles associated with it. The default value is true . If tomcatAuthorization is set to true this attribute has no effect.

Changes Required in server.xml for Apache Tomcat 8.5.51 after Upgrading to Access Manager 4.5 Service Pack 2

Access Manager 4.5 Service Pack 2 (4.5.2) adds support for Apache Tomcat 8.5.51. This version adds a secret required attribute to the Apache JServ Protocol (AJP) Connector. For fresh Access Manager installations, this string is specified in the server.xml file as secret= “namnetiq” by default. You do not need to make any change to server.xml in this regard.

However, the Tomcat service might not get loaded if you upgrade an existing Access Manager setup to 4.5.2 and Tomcat to version 8.5.51. You might see the following error in the Tomcat catalina.log file:

SEVERE [main] org.apache.catalina.core.StandardService.startInternal Failed to start connector [Connector[AJP/1.3-8009]] org.apache.catalina.LifecycleException: Protocol handler start failed Caused by: java.lang.IllegalArgumentException: The AJP Connector is configured with secretRequired=”true” but the secret attribute is either null or “”. This combination is not valid. ‘

To workaround this issue, after upgrading Tomcat to version 8.5.51, perform the following steps:

Open the server.xml file. This file is located in the following path: Windows: C:\Program Files\Novell\Tomcat\conf\server.xml Linux: /opt/novell/nam/mag/conf/server.xml Add the secret required attribute. Set it to true by specifying a a non-null or non-zero length string. NOTE:The value of this secret required attribute must be same in server.xml files of each component. For example: Embedded Service Provider configuration: Linux: /opt/novell/nam/mag/conf/server.xml /opt/novell/nam/mag/conf/server.xml ^M Administration Console: Windows: C:\Program Files\Novell\Tomcat\conf\server.xml Identity Service Provider (IDP): Windows: C:\Program Files\Novell\Tomcat\conf\server.xml Linux: /opt/novell/nam/idp/conf/server.xml ^M Save the file and restart the Apache Tomcat Service.

The following are examples of Apache vhost.d/*snippets:

Embedded Service Provider configuration:

Path: /opt/novell/nam/mag/webapps/agm/WEB-INF/config/apache2/vhosts.d/soapbc.conf

ProxyPass /AGLogout ajp://127.0.0.1:9009/nesp/app/plogout secret=namnetiq ProxyPass /nesp ajp://127.0.0.1:9009/nesp secret=namnetiq

Path: /etc/opt/novell/apache2/conf/vhosts.d/proxy.conf

ProxyPass /AGLogout ajp://127.0.0.1:9009/nesp/app/plogout secret=namnetiq ProxyPass /nesp ajp://127.0.0.1:9009/nesp secret=namnetiq
