Dear pvpalval:
This is from the APM Java Agent Guide
Cross-Process Transaction Tracing
The CA Introscope® Java agent can trace transactions that cross JVM boundaries on WebLogic Server or WebSphere. The environment must be comprised of compatible versions of the application server by the same vendor. Cross-process transaction tracing is supported for synchronous transactions, for instance servlets to EJBs, and asynchronous transactions.
Important! Cross-process transaction tracing is available only with CA Introscope® 9.0 agents at a minimum.
More information:
Enable cross-process tracing in WebLogic Server
Enable cross-process tracing in WebSphere
You read further in the documentation as required
Thanks
