error: Could not initialize dynamic link library sapjcorfc

[Former Member]

Hi, we just updated the 7.1 006 version to patch 007 and during this we had been seeing some issues relation to provisioning. Now during the we get error:

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 "2.1.8 (2006-12-11)" but required version "2.1.10 (2011-05-10)".

Can some one please suggest what we missed.

Thanks,

Hi Arun

You need to confirm that

• librfc32.dll is in System32
• sapjco.jar is in the classpath.

You might also want to check SAP Note 1682814.  I seem to remember that had something to do with it.

Hi Arun,

Currently, the latest patch level for SAP JCo 2.1 is version 2.1.10.

Hence, update the JCo version.

You should be able to find the downloads in https://websmp208.sap-ag.de/connectors > SAP Java Connector > Tools & Services.

Check out these two notes.

Note 723562 - SAP Java Connector 2.x: Configuration and Requirements

Note 549268 - SAP JCo 2.x release and support strategy

Cheers

Murali.
