Hi,

I think you need to copy and paste your librfc32.dll file in the same path were you have the jar file.

Please do not move or cut this file from its location.

Hi,

Check you have DLL librfc32.dll which comes with JCo download in C:\WINDOWS\system32

Check also that sapjcorfc.dll and sapjco.jar are in the same directory. Add this directory to your PATH environment variable.

Add a reference to sapjco.jar in your CLASSPATH environment variable.
