Hi all;  
  
are there any issues regarding using an EJB wrapper to call an RPC server via communicator version 6.1.1.8?  
The RPC server is Natural 3.1.5  
Natural and EntireX are running on OS/390 2.10

Hi Arp,  
  
no, there should be no issue using the EJB Wrapper with an older version of Broker/Communicator.  
  
Remember that you cannot use in your IDL the new data types which Natural currently does not understand (e.g. AV).  
  
Kind regards,
