Hi All
I am trying to develop an RCP (Rich Client Platform) application based
on the netbeans platform. Previously I have used TopLink, but would like
to move over to OpenJPA.
Any way my main problem is that I am getting the following exception
thrown when trying to connect to the database at start up.
Exception in thread "Attach Listener" Agent failed to start!
java.lang.ClassNotFoundException:
org.apache.openjpa.enhance.InstrumentationFactory
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
at java.lang.ClassLoader.loadClass(ClassLoader.java:306)

at
sun.instrument.InstrumentationImpl.loadClassAndStartAgent(InstrumentationImpl.java:280)
at
sun.instrument.InstrumentationImpl.loadClassAndCallAgentmain(InstrumentationImpl.java:348)
The application still manages to connect to the database. Do I need to
pass something to the main start up of the application. The jar file is
part of the program.
Thanks
David
