> Please find Stateless Session Bean Reference Binding implementation and corresponding sample attached with 
> this JIRA.  This contribution is from IBM to Apache as granted by the CCLA signed on 9 February 2007
> Implementation:-
> Stateless Session Bean reference binding enables SCA composite to consume service exposed by external
> Stateless EJB. This implementation conforms to current Stateless EJB binding spec.
> Reference binding implementation supports SCA composite running on both
> 	1) managed environment (J2EE)
> 	2) un-managed environment (J2SE)
> This implementation can lookup and invoke any Stateless EJB just with the URI and Reference interface from SCDL. 
> Key part of this implementation is caller (SCA composite with reference binding) doesn't need to include 
> EJB home class or client related stub classes of the EJB. (see a note below).
> Stateless EJB home lookup is done based on whether the SCA composite is running on managed/unmanaged environment.
> JNDI name gets resolved either from InitialContext or CosNaming context based on whether composite is running on 
> managed/un-managed environment and based on whether JNDI properties are configured or not. This implementation creates
> the stub based on the type of home object through java reflection or via RMI/IIOP. EJB method is invoked on the stub through java 
> reflection or through DII, based on whether the ejb object is local or remote.
> Sample:-
> EJB reference binding sample demonstrates how SCA composite can invoke Stateless Session Bean which is running on Geronimo.
> This sample exercises un-managed env path with configured JNDI properties. Using Geronimo application server, managed path or 
> locating through cosNaming is not tested.
> Note: Including home class at the caller (composite with reference binding) is required only if the EJB is running on 
> Geronimo application server which uses openejb.  This is not required for application servers like WebSphere.
> Tuscany revision:
> Binding implementation and sample code is compiled and tested with Tuscany SCA revision 497910.
