Setting up multiple ports on a single JBoss instance?

Question

Problem Context

Here\'s the situation. We are running a simulator servlet from a war. The servlet we are simulating has many instances on a single machi

You need to modify Tomcat's configuration (JBoss uses an embedded version of Tomcat).

Relevant file is:

$ $JBOSS_HOME/server/default/deploy/jbossweb-tomcat55.sar/server.xml

There is a portion where you configure the binding ports. This is what comes by default:

  <!-- A HTTP/1.1 Connector on port 8080 -->
  <Connector port="8080" address="${jboss.bind.address}"
     maxThreads="250" strategy="ms" maxHttpHeaderSize="8192"
     emptySessionPath="true"
     enableLookups="false" redirectPort="8443" acceptCount="100"
     connectionTimeout="20000" disableUploadTimeout="true"/>

You can add several "connectors". One for each port you need.

Then restart your JBoss.

You will see something like this on the LOG:

16:29:13,803 INFO  [Http11BaseProtocol] Initializing Coyote HTTP/1.1 on http-0.0.0.0-8080
16:29:13,804 INFO  [Http11BaseProtocol] Initializing Coyote HTTP/1.1 on http-0.0.0.0-8091
16:29:13,805 INFO  [Http11BaseProtocol] Initializing Coyote HTTP/1.1 on http-0.0.0.0-8092
16:29:13,805 INFO  [Http11BaseProtocol] Initializing Coyote HTTP/1.1 on http-0.0.0.0-8093
16:29:13,805 INFO  [Http11BaseProtocol] Initializing Coyote HTTP/1.1 on http-0.0.0.0-8094

This is what you need to add on your server.xml file:

  <Connector port="8091" address="${jboss.bind.address}"
     maxThreads="250" strategy="ms" maxHttpHeaderSize="8192"
     emptySessionPath="true"
     enableLookups="false" redirectPort="8443" acceptCount="100"
     connectionTimeout="20000" disableUploadTimeout="true"/>

  <Connector port="8092" address="${jboss.bind.address}"
     maxThreads="250" strategy="ms" maxHttpHeaderSize="8192"
     emptySessionPath="true"
     enableLookups="false" redirectPort="8443" acceptCount="100"
     connectionTimeout="20000" disableUploadTimeout="true"/>

  ....

One XML tag for each new port.

One doubt, since all the connections are redirected to 8443, what is the point in giving multiple configuration? will it avoid port congestion?
