Unable to import adaptive RFC model - NWDS plugin problem

[former_member182374]

Hello Experts,

I'm trying to import Adaptive RFC Model with NWDS 7.02 SP6.

I get to the logon information screen in the wizard and when I hit the 'next' button I get an error:

Web Dynpro Model Editor Services

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

Moreover, when I try to connect to the same system from other NWDS versions (like 7.00.15 and 7.00.22) I don't get error.

I think the problem is with the NWDS 7.02 SP6 plugins.

Since the code is under NWDI I must use the same NWDS version as my J2EE server (which is 7.02 SP6).

This is NWDS log file from the .metadata directory:

After some digging and playing with the librfc32.dll file I got this exception:

Exception : 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 sapjcorfc. Found version "2.1.9 Hotfix (2010-05-11)" but required version "2.1.9 (2010-01-28)".)

Then, I replaced the "com.sap.mw.jco_2.0.0" plugin of 7.02 SP6 with the plugin of 7.00.22 and it started to work.

I've already open a message but if someone had similar problem...
