Karim,

First of all, this is a list for development of Spring itself. You 
should be using the forums at forum.springframework.org, for help...

As to your problem, I think your Local Interface does not actually 
implement your business interface... The proxy is blowing up at:

ejb = getSessionBeanInstance();
return invocation.getMethod().invoke(ejb, invocation.getArguments());

basically the local interface that the ejb stub which comes back has, 
does not match the class on the actual Method object, which is coming 
from what you declared on the proxy...
