Customize open source help-desk project

The project is to use open source help-desk/ issue tracker project and integrate it into existing J2EE server. The project should include the following steps: 1. Choose either jTrac or iTracker as help-desk software. (Could be other, but should have good reason for it, the main functionality I need is issue-tracker and email notification) 2. Prepare an eclipse project environment, so I will be able to easily import the project and make changes in help-desk project source code. 3. Show basic integration between the help-desk project and my existing web project (i.e. show deployment in server and basic scenario) 4. Customize the UI via CSS to match the site: [login to view URL] (could be not 100% accurate) ***Note: If you can do only partial work, please mention it.
