Debug my web application using ant

Question

I am currently developing an MVC Application using Java EE Technologies and Eclipse as an IDE. To run my server and deploy my application I am using ANT. I would like to know how can I debug my Java Code through the ant tool or eclipse.

Answer 1

Add the following jvmarg options to your tomcat start command:

<jvmarg value="-Xdebug"/>
<jvmarg value="-Xrunjdwp:transport=dt_socket,address=5000,server=y,suspend=n"/>

You will be able to attach the Eclipse debugger on port 5000, using the Remote Java Application debug category.

Answer 2

You can do that from eclipse:

• enable debug on tomcat
• create a new debug configuration in eclipse that connects to tomcat

See here for details.

But it is not a good idea to use ant to start tomcat in development. Use Eclipse WTP to start your tomcat and deploy applications on it.
