Question

I want to start debug mode for my application. But I need to start the debug mode from command prompt. Is it possible ? And will the procedure vary between tomcat 5.5 to tom

Answer 1

1. From your IDE, create a remote debug configuration, configure it for the default JPDA Tomcat port which is port 8000.

2. From the command line:

   Linux:

   cd apache-tomcat/bin
   export JPDA_SUSPEND=y
   ./catalina.sh jpda run
   

   Windows:

   cd apache-tomcat\bin
   set JPDA_SUSPEND=y
   catalina.bat jpda run
   

3. Execute the remote debug configuration from your IDE, and Tomcat will start running and you are now able to set breakpoints in the IDE.

Note:

The JPDA_SUSPEND=y line is optional, it is useful if you want that Apache Tomcat doesn't start its execution until step 3 is completed, useful if you want to troubleshoot application initialization issues.
