I am new to the product but so far, excellent first impression.
I am trying to run with an old Websphere App Server version: 6.1 (dont ask!).
After trying latest YourKit version i noticed that JDK 1.5 is no longer supported and i downloaded last version supporting JDK 1.5, where WAS 6.1 is present in J2EE servers integration list.
After switching server.xml server starts fine i can connect the agent but my Web app deployed on WAS 6.1 ends up in a ClassNotFound exception for a Java class!
I checked the classpath of server when agent is configured and is identical with the one "without" which works fine!
The only change that makes the error appear is this config in server.xml:
-agentpath:C:\PROGRA~2\YOURKI~1.30\bin\win32\yjpagent.dll
And here is the resulting error:
Caused by: java.lang.ClassNotFoundException: java.util.ServiceLoader
Any hints if I need another version in order to profile WAS 6.1?
thanks,
Stefan

Re: yjpagent.dll wih Websphere JVM
Hi Stefan
Indeed, WAS 6.1 runs on Java 5 and the latest YourKit version supporting Java 5 is YourKit Java Profiler 8.0 which is now unsupported.
I can only suggest the following:
- Try to specify the agent startup option "disableall" to disable all optional profiling capabilities. If it helps you may try to choose a subset of other less strict "disable*" options.
- What is the full exception stack trace? If the issue is related with OSGi restricting class loading, try to add com.yourkit.* to the list of allowed classes. Please refer to OSGi docs on how to do this.
Best regards,
Anton

Re: yjpagent.dll wih Websphere JVM
I don't see any YourKit code in the stack, and it's unclear what went wrong in particular.
At the moment I have no better recommendation than to try the "disable*" options as I earlier suggested.
