How to run Tomcat on a different port number

How to run Tomcat on a different port number
Tomcat web server by default runs on port number 8080, which is also the default port number used by some other popular servers like JBoss, JavaEE SDK, Sun Java System Application Server. When this port number is already used by another process, you will get the following error:logs/catalina.2007-01-09.log:...INFO: Starting Servlet Engine: Apache Tomcat/5.5.20Jan 11, 2007 9:36:12 AM org.apache.catalina.core.StandardHost startINFO: XML validation disabledJan 11, 2007 9:36:13 AM org.apache.coyote.http11.Http11BaseProtocol startSEVERE: Error starting endpointjava.net.BindException: Address already in use: JVM_Bind:8080 at org.apache.tomcat.util.net.PoolTcpEndpoint.initEndpoint(PoolTcpEndpoint.java:297) at org.apache.tomcat.util.net.PoolTcpEndpoint.startEndpoint(PoolTcpEndpoint.java:312) at org.apache.coyote.http11.Http11BaseProtocol.start(Http11BaseProtocol.java:150) at org.apache.coyote.http11.Http11Protocol.start(Http11Protocol.java:75) at org.apache.catalina.connector.Connector.start(Connector.java:1089) at org.apache.catalina.core.StandardService.start(StandardService.java:459) at org.apache.catalina.core.StandardServer.start(StandardServer.java:709) at org.apache.catalina.startup.Catalina.start(Catalina.java:551)To use a different port number, back up and edit the port attribute value of Connector element in ($CATALINA_HOME/conf/server.xml:Connector port="8081" maxHttpHeaderSize="8192"Restart Tomcat ($CATALINA_HOME/bin/startup.sh on Unix or %CATALINA_HOME%\bin\startup.bat on Windows), and check server status at URL http://localhost:8081)
