Here is the link to the EjbWebServiceServlet code
https://glassfish-svn.dev.java.net/source/browse/glassfish-svn/trunk/v3/webservices/jsr109-impl/src/main/java/org/glassfish/webservices/EjbWebServiceServlet.java?rev=25600&view=markupThis
is the
 link to the EjbMessageDispatcher implemenetation
https://glassfish-svn.dev.java.net/source/browse/glassfish-svn/trunk/v3/webservices/jsr109-impl/src/main/java/org/glassfish/webservices/Ejb3MessageDispatcher.java?rev=25054&view=markup
Please let me know your recommendation

Thanks,
