java.lang.UnsatisfiedLinkError: E:\SAP\sapjco3.dll

Hi All,

I am new to SAP Netweaver.

I am trying to write a standalone java program to execute few RFMs. I am using JCO 3.0. The program works on my laptop. But when I deploy the same program to the server, the dll does not work. I get the following error.

java.lang.UnsatisfiedLinkError: E:\SAP\sapjco3.dll:

This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem

I am not sure what reinstalling means. We just have to extract the jar and dll files and put them in classpath and path.

The server OS is Windows 2003 Server.

Am I missing something?

Thanks,

Daya
