I have solved this problem in tomcat. How?

I have copy sapjac.jar and sarprfc.dll under to tomcat/common/lib and tomcat runs succesfully.

But how can i run in portal? Where do i copy the this files?

Thanks

Hi Eray,

Congratulation!!! You got the solution!!!

The applications in Portal resides @ X:\usr\sap[SID]\JC00\j2ee\cluster\server0\apps\sap.com

Find your application there inside your application there will a WEB_INF directory.

Inside it there will be a folder named "classes" at this level create a folder named "lib" insert all your related lib files there and then after restarting the server you can check whether your problem is solved or not.

Let me know if the problem still exists!!!

Regards,

Prashil

Hi Prashil;

Thank you so much.. I did also in SAP Portal. I have copied these files and it is ok!

Best Regards

Hi Eray,

Is it happening to only this application?

Since it seems error related to the lib files not found. Please set your enviorment variables properly, check your classpath and required library files are there in the given path.

Let me know if the problem exist!!!!
