u0093Class not foundu0094 for Web Dynpro API class

[Former Member]

Hi,

After installing Web AS 6.40 (Java) and the Netweaver Developer Studio (2.0.12) I tried a simple “hello world” example (just a WebDynpro view with a static text, without any further view elements or program logic).

When deploying and starting I constantly receive the following runtime message (top of stacktrace):

“java.lang.NoClassDefFoundError: com/sap/tc/webdynpro/progmodel/api/IWDEventHandlerId”.

“IWDEventHandlerId” is a class delivered with Netweaver Developer Studio. It should be found as further down in the stacktrace I read

“at com.sap.tc.webdynpro.progmodel.generation.ControllerHelper.createDelegate(ControllerHelper.java:68)” and

“at com.sap.tc.webdynpro.progmodel.generation.DelegatingInterfaceView.<init>(DelegatingInterfaceView.java:44)”.

Classes “ControllerHelper” and “DelegatingInterfaceView” are obviously found and they are contained in the same jar file as “IWDEventHandlerId”! The jar file is …\JDT\eclipse\plugins\com.sap.tc.webdynpro.runtime\lib\_webdynpro_progmodel.jar.

Has anyone had a similar problem and found a solution / a workaround?

Thanks in advance

Hi Thomas,

This error is coming due to the version mismatch between your Netweaver developer studio and WAS version. Your NDS version should be same or lower than your WAS version, otherwise it will give such errors.

Can anyone letmeknow which version of Netweaver Developer Studio suits for SAP WAS6.0 SP9

Currently I'm with NDS 2.0.16 and SAP WAS6.0 SP9..

Please tell me what should i do now...

Yes the version hint ist correct, thank you all.

I had a version mismatch:

Developer Studio 2.0.12 vs. Web AS SP 9.

Developer Studio 2.0.9 and Web AS SP 9 fit together (and DevSt 2.0.12 and Web AS SP 12 will, too, I suppose).

You have different runtime versions (NWDS runtime is newer than Web AS version). If you adapt versions, the error will disappear.

I think Armin is right, what is your WebAS SP level? Your NWDS is on SP12 (2.0.12)...
