I'm trying to use Jena 2.13.0 with Pellet; I downloaded the latest Apache Jena library 2.13.0.

Then, I downloaded the jar file pellet-jena-2.3.2 and imported the JENA libraries.

But i get this exception:

You need the other pellet jars in the classpath. Probably the one missing is pellet-core.
Hth,

I have tried compiling Pellet source with Jena 2.13.0 and got
compilation errors, so I'm afraid this is not going to work with just
replacing jars.

[INFO] -------------------------------------------------------------
[ERROR] COMPILATION ERROR :

There's at least one code change that needs to be done.
Cheers,

if I want to use the reasoner Pellet jena, I have to use a specified Version of Jena ?
