    Last week I was able to successfully reverse engineer all our entity beans using the “EJB3 Reverse Engineering” wizards; however, today when I went to reverse engineer the new tables nothing happens (no dialog pops up). If I look at the eclipse error .log file I see the attached exception thrown. Any suggestions on how to get this to work would be greatly appreciated. 🙁

    anthonyestelita,
    Can you switch to a new workspace and try rev engg again. Does it still throw similar errors ?

    I created a new workspace. and I re-checked out my .ear, .war, and my two .ejb projects. and the revers engineering works there. Is there a property/setting file in my workspace that I can delete/reset to get this to work.

    Try cleaning you workspace using the -clean command line argument. Thats the only thing you can do to try and get things to work in your old workspace.

    i already added the -clean and -refresh in my eclipse.ini file already (see my above “MY ECLIPSE INFO” at the end). Anything that I can remove/fix manually?

    Thanks,
    Anthony

    Anthony,
    The only thing that you can do now is switch to the new workspace and import your projects into the new workspace.

    I ended up doing that yesterday, and was able to re-regenerate my EJB3 entity beans. However, today, with much surprise, it isn’t working again in my new workspace. — UGH! ;-( For a workaround, I just re-created a simple workspace that just contains my EJB project just so I can reverse engineer my EJB3 files. Have you heard of anyone else having this problem? I just cant see what I could be doing that keeps on corrupting my workspace.

    Oh well, thanks for the help.

    And please let me know if you can find a better solution/workaround (it is kind of painful to have to create a temporary workspace just to do my reverse engineering – thankfully we don’t have to reverse engineer our EJB3 that often) 🙂

    Do you have any additional plugins installed along with MyEclipse ?

    Nope, all I have is MyEclipse. Why would anyone need anything else? ;-D

    I found a workaround that is a lot better/easier then creating a temporary workspace every time we need to reverseEnginner something:
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    1. Open up the following file:
    [workspace]\.metadata\.plugins\org.eclipse.core.runtime\.settings\com.genuitec.eclipse.hibernate.prefs
    2. Delete the line that looks something like:
    EJB3_com.genuitec.eclipse.hibernate.JAVA_FOLDER=/myProject.ejb.jar/src
    3. Restart eclipse
    4. Voila 🙂
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Hopefully this will help someone that may also be having this problem (and also hopefully it will help the myEclipse developers fix this issue). 🙂

    Have fun,
    Anthony
