I'm attempting to profile a web app running inside Oracle Containers for Java (oc4j). At start up I specify -javaagent:<location of the profile.jar> and -Dprofile.properties=<location>/webapp.profile.properties.
Everything starts up fine, I run the app a couple of times to get everything loaded and then turn on the profiler. I run the test turn off the profiler a look at the log and the only methods that are getting profiled are oracle.oc4j.network.*.
Next run I turned on debug and it became clear why my app wasn't getting profiled. The log was filled with <Time stamp> Catch: java.lang.ClassNotFoundException
<Time stamp> skip <my.app.class> [oracle.classloader.PolicyClassLoader]
I guess my first question is does JIP work with oc4j? I suspect I'm missing something trivial here but I'm relatively new to profiling Java code. Heck, I'm relatively new to Java being an old C programmer learning a new bag of tricks.
I've gotten this working just fine on standalone Java code and it's proved very useful. I'd like to do the same for a web app running in a container.
