If you followed with the quick demo installation instructions (User Guide for jbpm 4.4), you already have an eclipse with the project "examples" installed.
There is a special deploy ant task defined in the build.xml file, inside the "examples" project.
When you run this task in the ant plugin of eclipse you will notice that all of the example processes are redeployed. Cince then you can see their never versions in the jbpm-console.
Try to develop your own process next to existinge example ones and run this deploy-task again - After that your new process will be visible in jbpm-console.
