Access EJB 3.0 (deployed on Glassfish v3) from Tomcat 6.0.20 (Netbeans 6.8)

Question

Hi all,
I'm a newbie (of java EE and Sun forum).
I have a problem.
I followed this tutorial: http://technology.amis.nl/blog/1368/connecting-to-an-ejb-30-remote-sessionbean-from-tomcat
using Netbeans 6.8, Tomcat 6.0.20, Glassfish v3.
The deploy of EJB on Glassfish is OK.
The deploy of WebApp on Tomcat is OK.
But when I access to the servlet using the browser I receive this exception.

I know that I must copy *.jar files in Tomcat dir and App libraries (https://glassfish.dev.java.net/javaee5/ejb/EJB_FAQ.html#Step_3._Include_appserv-rt.jar_and), but it doesn't work.
What are my mistakes?
Thank you for your help.

Answer 1

Yes, I did.
I'm not sure about the right actions to do.
For example: the Glassfish FAQ told me to add gf-client*.jar to the Tomcat folder, not appserv-rt.jar , with v3.
I tried with both files. I restarted Tomcat, but nothing work :-(
