How to run different apps on single Tomcat instance behind different ports?

Question

Currently I have 2 web applications app1 and app2 running on Tomcat 6:

• app1 on http://localhost:8080/app1
• app2 on http://localhost:8080/app2

I want to configure Tomcat so that they run in root context behind separate ports:

• app1 on http://localhost:8081
• app2 on http://localhost:8082

What needs to be done?

Another example of adding connectors:

<Service name="reciver">     <Connector port="8080" maxHttpHeaderSize="8192" maxThreads="10"                 enableLookups="false" acceptCount="100"                connectionTimeout="10000" disableUploadTimeout="true"                 useBodyEncodingForURI="true"/>     <Engine name="reciver" defaultHost="localhost" jvmRoute="host1">             <Realm className="org.apache.catalina.realm.UserDatabaseRealm"                    resourceName="UserDatabase" />             <Host name="localhost" appBase="webapps" unpackWARs="true"                   autoDeploy="false" xmlValidation="false"                   xmlNamespaceAware="false">                     <Context docBase="browser" path="/browser" reloadable="false"/>             </Host>     </Engine> </Service> <Service name="reciver2">     <Connector port="8081" maxHttpHeaderSize="8192" maxThreads="10"                 enableLookups="false" acceptCount="1"                connectionTimeout="10000" disableUploadTimeout="true"                 useBodyEncodingForURI="true" proxyName="example.pt" proxyPort="80"/>     <Engine name="reciver2" defaultHost="example_app" jvmRoute="host2">             <Host name="example_app" appBase="test_app/example_app" unpackWARs="true"                   autoDeploy="false" xmlValidation="false"                   xmlNamespaceAware="false">                     <Context docBase="example_app" path="/example_app" reloadable="false"/>             </Host>     </Engine> </Service> (...Repeted 2 more times.)

I recommend reading the whole thread, as it talks about performance hits with this configuration, and also possible race conditions.

I think you can configure that in you server.xml file and put 2 services :

<Service name="app1">    <Connector port="8081" protocol="org.apache.coyote.http11.Http11NioProtocol"             connectionTimeout="20000"             redirectPort="8443" />    <Engine name="Catalina" defaultHost="localhost">       <Host name="localhost"  appBase="app1"         unpackWARs="true" autoDeploy="true">       </Host>    </Engine> </Service> <Service name="app2">    <Connector port="8082" protocol="org.apache.coyote.http11.Http11NioProtocol"             connectionTimeout="20000"             redirectPort="8443" />    <Engine name="Catalina" defaultHost="localhost">       <Host name="localhost"  appBase="app2"         unpackWARs="true" autoDeploy="true">       </Host>    </Engine> </Service>
