Yes, I am using OpenEJB in tomcat.

I reinstalled everything from scratch and it worked now. I might have
done some mistake during installation.

That's good news.  Glad it's working.

I am getting above error in my linux box and everything works fine in

think that it is required for OpenJPA. Is that true? For what else
it is
required and how to resolve that error in linux box?

Right, it is only required for OpenJPA.  If you use Hibernate you'll
never see that message.

This url should have been printed in the error message -- definitely
let us know if it wasn't and we'll fix it:

  http://openejb.apache.org/3.0/javaagent.html

That should contain the info you need.  We can definitely improve that
page too if you have suggestions or it doesn't really answer all your
questions.

As for why you might see it on one box and not the other has me
puzzled.  Are you using OpenEJB in Tomcat, embedded in a plain Java SE
app, or as a stanalone server process?  Depending on the setup we
could give you things to check for.
