[Pellet-users] Using pellet in JSP

[Daniel Malek]

Ron , Thank you for your reply .

I removed the 4 pellet 1.3 jar files , and added the 3 pellet 1.4 jar files.

I get a new error message which is attached below.

By the way, by using pellet 1.3 and Jena 2.5.2 through the command line (Not 
JSP) I am able to run the java code without problems. But when I need to put 
it in JSP, I get the error attached in my previous post.

Any tips is extremely apprecitated.
