emma error - while extracting coverage

[Anand Balasubramanian]

We are getting the following error while extracting the emma coverage

1) Java compile - done
2) emma instument - done
3) deploy ear to webspehere and updated the path with emma jars
4) extract the coverage - FAILED here with below error.

This got fixed.

The Java path used for the AppServer and extract command was
different. This was causing the error.

We used the AppServer(websphere) java and it extracted the coverage.

This is fixed by using appserver(IBM) java for extracting the
coverage. Earlier, we used different java (SUN) for extracting, where
appserver was using IBM Java, hence the exception.

Could you please send the solution for this issue.
