    When I am trying to start weblogic8 I am getting following message. It used to work before suddenly after removing some classes to my project, I am getting this error. This is still coming even after reverting back to the changes I made. I am using myeclipseide 4.1.1 GA and Eclipse 3.1.2 and JDK 1.4.2_05. I read in this topic https://www.genuitec.com/forums/topic/tomcat-app-server-preferences-not-picking-up-sdk/#post-244422
    that full SDK is required. I did this as well.
    I also downloaded jmxri.jar added to my classpath, and verified that addClassLoader method is present in it. Any solutions on this would be helpful and thank you in advance

    Praveen,
    Does WebLogic start outside of MyEclipse? Also be sure you configured it to run with the JDK that comes with WebLogic and not some other installed JDK.

    Additionally, why did you need to download jmxri.jar if it used to work just fine without it? That might be confusing the issue.

    Thank you for the reply, I was able to run it by removing j2ee.jar from weblogic class path. For some reason I uninstalled myeclipseide and tried with Eclipse weblogic plugin. Its working now.
