Hi cj:

I think that you have some things to do.

See,

1) the JDK you are using for JCO i think is not supported for JCO.

I think that your error message is clear, you have to down up of version...

Could not initialize dynamic link library sapjcorfc. Found version "6.30.0 (2003-03-14)" but required version "2.1.6 (2005-06-20)".

For more informatin see:

Good luck

Are you sure you are using a proper sapjco.jar file and the other 2 required DLL files i.e. sapjcorfc.dll and librfc32.dll??

You will need to make sure that all these files you are using are in sync with your R/3 version. and the PATH variable on your local system should have the entry for the folder where your DLLs are placed.

Hope this helps.
