hi padma,

error come up, because jco over jni has no access to the dll libaries. maybe the used files are corrupt...

however, you can download the jco libs for the right os under:

Hi,

The zip file which contains the JCo jar also contains the dlls. If you got the Jar from someone in your company, ask him/her for the dlls. To access the link mentioned, you need an S-User account from SAP.

hi padma,

1) click on SAP Java Connector in the main screen

2) in the tree on node "Tools & Services"

3) Quick Links --> Download SAP JCO Release XXX

4) Windows NT / Windows 2000 ... select 32 or 64bit

in this zip you will find your dll's.
