08. Debugging with the JBoss IDE

1. We will configure a tomcat server in the Eclipse IDE. We will use this to run the Tomcat application server with the platform deployed as a web application.
2. Last, we will place a breakpoint in the platform Java code, run the 'Hello World' sample solution, and step through the code from that breakpoint.

   If you intend to follow the "Debugging with Tomcat in the Eclipse IDE" exercise, you will want to make sure you do NOT have another application using port 8080 on your computer. This is the default port for the tomcat application server. While you can change the port that the server looks to use, you do not want to unnecessarily complicate your life at this point. If port 8080 is in use, we recommend temporarily shutting down the application that is using port 8080 while you are running the application server.

Configuring the Tomcat Server

Now that you have the pentaho web application copied into the pentaho-tomcatpreconfiguredinstallproject, it's time to start up the Tomcat application server and make sure everything works. The Eclipse IDE is a pretty sweet tool. It's easy to configure, and once that's done, all you have to do is start the server through the IDE and you can debug Java code.

Configuring a Tomcat Server in Eclipse IDE

These instructions work for anyone running the recommended environment as described in Setting Up Your Environment doc.
