    Hello everyone,
    the problem is resolved by adding all the jar files in the classpath of my second project!!!
    I don't know if this is the right solution! but the essential my second example works:))
    If you have any answers, please do not hesitate

    ScopedClassPoolFactory is contained in the jboss-classpool-scoped.jar, this jar must be in the classpath so the JVM can load the agent code correctly.

    Sorry, it isn't. It is part of javassist.jar (see full name of the class: javassist.scopedpool.ScopedClassPoolFactory and you can also check it in the mentioned jar file).


    But when I add the javassist.jar, it requires jboss-common-core.jar, then jboss-logging-spi.jar and then trove.jar. After all I get a message:


    ERROR: transport error 202: gethostbyname: unknown host

    ERROR: JDWP Transport dt_socket failed to initialize, TRANSPORT_INIT(510)

    JDWP exit error AGENT_ERROR_TRANSPORT_INIT(197): No transports initialized [../../../src/share/back/debugInit.c:690]

    FATAL ERROR in native method: JDWP No transports initialized, jvmtiError=AGENT_ERROR_TRANSPORT_INIT(197)


    Any idea?

    Where can I get jboss-classpool-scoped.jar from?

    I downloaded jBoss pojo cache and I am getting the same error mentioned above, but I do not see this jar in the lib folder.  Googling it did not produce much.
