How to do code coverage for a remote repository using eclEmma

Here is my scenario.

1. I have a code base, which is built and deployed as EAR.

2. I have a separate testing framework.

3. Now I want to run the classes of that EAR using my testing framework.
4. The test cases are written in TestNG.
5. Also I want to know the code coverage of the EAR.
6. I have used eclEmma to do code coverage for Junits, it was simple as the code and tests are at same place. How can I use eclEmma in the case of remote code base. Please help.
