in ejb3.0 project, wizard for new EJB Session Bean 3.0 doesn't come up

[Former Member]

When I try to create a EJB 3.0 SessionBean, I get the following error:

The selected wizard could not be started.

Reason:

Plug-in com.sap.ide.j2ee.ui.ejb was unable to load class com.sap.ide.j2ee.ui.ejb.wizard.SessionBeanWizard

Details:

com/sap/j2ee/ui/ejb/wizard/SessionBeanWizard (Unsupported major.minor version 49.0)

Note: As seen in the thread below, I have just re-installed the appserver and dev studio:

Hi Makarand,

The message "Unsupported major.minor version 49.0" implies that you are running with JDK version < 1.5. Please check in your workspace\.metadata\.log file - there should be some entries like:

java.version=1.5.0_07

java.vendor=SAP AG

BTW, have you started the NWDS from the Start Menu -> Programs -> SAP NetWeaver -> SAP NetWeaver Developer Studio? If you are using C:\SAP\DevStudio\eclipse\SapNetweaverDeveloperStudio.exe directly it could be that it finds some older JRE installed on your machine.

Hope that helps!

Thanks, I had started teh dev studio directly and not from the shortcut, hence the problem.

Hi Makarand,

Might be also the reason for the problem with the EJB 3.0 project wizard described in your other thread. I mean nobody else has complained about its functionality.

Just FYI: If you are interested, please refer to my reply there why the shortcut is the preferred way for starting the NWDS.
