Tomcat tricks and debugging with JRebel

Tomcat Tricks

Resolve character encoding

Adding URIEncoding in Connector configuration like following.

<Connector executor="tomcatThreadPool"
   port="8080" protocol="HTTP/1.1"
   connectionTimeout="20000"
   URIEncoding="UTF-8"
   redirectPort="8443" />

Using Tomcat with JRebel

Get Tomcat Ready

Use following commands to start or stop tomcat, Tomcat will open a 8000 port for remote debuging.

tomcat-start.sh

#!/bin/bash
export JAVA_OPTS="-javaagent:/Library/jrebel/jrebel.jar -Drebel.remoting_plugin=true $JAVA_OPTS"
/Library/Tomcat/apache-tomcat-7.0.56/bin/catalina.sh jpda start

tomcat-stop.sh

#!/bin/sh
/Library/Tomcat/apache-tomcat-7.0.56/bin/catalina.sh stop

Get IDE Ready

Create a new remote debug, and set the port to 8000. It is better to install a JRebel plugin, it help you to redeploy latest changes to Tomcat.
