Is there and IDE integration to Embarcadero XE2/XE3

I'm assuming you are asking about Rational Team Concert integration.

If XE2 or XE3 is based on a supported version of eclipse (e.g. 3.6 for RTC 4.x) then you could try installing RTC as a p2 repository like this:

• Download the "p2 Install Repository" zip from "All Downloads" tab of the RTC download page from jazz.net (use the version that matches the version of RTC your server is using)
• Unzip the p2 zip
• Launch eclipse
  
• Go to Help->Install New Software...
• Click "Add..."
• Choose "Local" and pick the location where you unzipped the p2 install
• Add the RTC feature for your install
• Restart eclipse

Otherwise, you could try using the RTC SCM command-line interface (CLI) and a web browser for your work items.
