How to use EJB step in Devtest

Question asked by Avinash_304 on Aug 6, 2015

Hi I am trying to perform tutorial 7 from lisa guide.

 

I have added the EJB step and provided the "Localhost" as server name where demoserver is running.

 

When I clicked on next, EJB step took some time to get the objects by connecting to server. But at end I got below error

 

Please help how to sort this issue.
