Subject Re: Java, Stomp, & Web Sockets
Date Tue, 21 May 2013 20:52:46 GMT
Hi Christian,

Thanks for responding.

Unfortunately the server side messaging infrastructure to which we are
trying to connect only exposes Web Sockets that utilize the Stomp protocol.

How can my Java client use the JMS API to communicate with that server side
infrastructure?

Thanks,
-h
