Hi Narinder,

I couldn't find any download option in the page you have mentioned.Can you please help me out.

Goto http://service.sap.com/connectors -> SAP Java Connector

But that page also doesn't have any download option I believe.

Go one level deeper -> Tools & Services.

Hi Prajesh,

This is a problem caused by the fact that the Java compiler or interpreter cannot find the JCo application libraries in your system path.

Depending on the operating system your are running, these are the non-Java link libraries that come with the JCo installation.

Go through this link carefully, your answer lies in this

page.
