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.

Hi Bo,
roughly, the IDE patch level or better service package level corresponds to the last digit of the version you can see at: Help->About SAP NetWeaver Studio (2.0.4 = SP04).
The system information is available at the J2EE engine home page http://<yourhost>:50000/
There should be a link "System Information". After login as admin you see a "Software Components" list and the SPx under "Version". I'm not sure, if Sneak Preview already has this feature.
But anyway, since you didn't update IDE or engine, a mismatch can't be the error reason.
Did you install SAPJCO separately or a SAP GUI after the WAS installation?
Regards
Stefan
Hi Stefan,
Thank you for your quick answer. I am not install SAPJCO separately. The system information show me the server version is 6.30 SP5. The IDE version is 2.0.5. I also checked the plug-in for JCo & JRFC libs. Both of them version are 2.0.0. But I also find librfc32.dll (in c:/winnt/system32/) version is 6205.5.949. I am not sure this number is the same number in error message or not. In error message, the number is 620.0.949. In this case, do i need to apply patch for my IDE or I should apply patch for my server?
Thanks,
Bo
