Problem with EJB wizard

[mbuchholz]

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

[tunahacker]

I have the same problem...does anyone have any solution to this?

[mbuchholz]

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?

[snyderpa]

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
