    Problem with EJB wizard

      Hi,

      I always get an error when I try to use the EJB wizard.
      My steps:
      - create new J2EE 1.4 Project "LCDTest"
      - create a package "de.lcd.beans"
      - click with right button on package -> new -> other -> ejb components -> Session Bean (EJB wizards pops up)
      - then I enter the package (de.lcd.beans) the name of the bean (testBean) and hit "finish"

      Then I get the following error:
      --snip--
      Creation of element failed.
      Reason: <project-root> [in LCDTest] does not exist
      --snap--

      Am I doing something wrong or is my eclipse/jboss-ide installation messed up?

      My System:
      - Java 1.4.2_04
      - Eclipse 3.0.1
      - JBoss IDE 1.4

      Thx for any help.

      Michael

              I've found out what the problem is.

              If you go through the tutorial (and I guess we did that all in this thread) you have to create a "source folder" where the EJBs are stored in and not a simple "folder". When I do this everything works fine for me...

              I don't exactly understand what the difference is between these two. Might be that the "source folder" is in classpath and the other not... any other difference?

                Much later, I experienced same problem in my log file as macifl.

                I solved it by running Eclipse with 512M virtual memory.

                shell-prompt: eclipse -vmargs -Xmx512M
