Hi, I am a new Java Connector user. I wrote a simple TutorialConnect1 java class to test my SAP system connection. But I got the following error:

ava.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".

at com.sap.mw.jco.JCO.<clinit>(JCO.java:735)

at TutorialConnect1.<init>(TutorialConnect1.java:29)

at TutorialConnect1.main(TutorialConnect1.java:61)

Exception in thread "main"

How do I update the version of my librfc?

Thanks for the help.

I apologized I could not recall anymore. The post was 8 years ago. I am sure the package is quite different now. Wish you able to find solution from other experts.

Hi,

you can download newer version of the SAP JCo package from http://service.sap.com/connectors -> SAP Java Connector.

I am getting problem in connection with SAP via SAPJCO connector in solarisX86 machine. The sap provided libraries are not working in my app server. Following error is comming when i try to connect to the SAP via sap jco connector for solarisx86:

Could not initialize the SAP jCO. Please reinstall and check that the needed libraries (librfc32 and sapjcorfc) are available to Java and restart this application. ==>
