I have successfully run this example using Eclipse 3.4.1 and Geronimo 2.1.3,
and only the CalcServlet code was a bit differnent:
----------------------------------------------------------
@EJB(name = "ejb/CalculatorRemote")
private CalculatorRemote calculator;
-----------------------------------------------------------
And I didn't package EJB and Web as a EAR, but added the EJB project to the
build path of Web project, and use "Add and Remove Projects" in Eclipse
plugin.
Hope this page gives you some hint:
