Error message when create model in Web Dynpro

Hi Gurus,

I want to create a models to import adaptive RFC model into WebDynpro. When I specify the SAP server to connect, I choose single server and enter the logon information for the SAP server. I got follow error messages said:

org.eclipse.swt.SWTException:

Failed to execute runnable (java.lang.ExceptionInInitializerError: JCO.classInitialize(): Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'

JCO.nativeInit(): Could not initialize dynamic link library librfc. Found version "620.0.949" but required at least version "620.0.1374".)

org.eclipse.swt.SWTException: Failed to execute runnable (java.lang.NoClassDefFoundError)

Do you know why I got above messages? Is there anything wrong with the version of NWDS? Please help.

Thanks,

Bo

    Hi Bo,

    does the server patch level match the IDE patch level? I guess, you updated the IDE and the newer JCO runtime expects a DLL, which would be updated by the corresponding server update to match the version requirements.

    Regards

    Stefan

      I solve the problem by myself. The problem is the librfc32.dll version conflict. I just simply reinstall the IDE and then the problem gone.

      Regards,
