Exposing an esb service to both java and non java applications (JBR?)

[kotaris]

Hi,

We are implementing JBOSS ESB in our organization. All JBOSS applications can use JMS and send message to Queues to invoke the service, How can non java applications (like microsoft .NET applications) call the service? If we have JBR Provider and Listener can they use that to call the service? Does that require them to have jboss-remoting.jar?

We are trying to see if we can expose esb services to both java and non java applications with out web services.

Take a look at the ESB Programmer's Guide :

http://docs.jboss.org/jbossesb/docs/4.10/manuals/html/Programmers_Guide/index.html

There's a section on Gateways which should explain what protocols are suppported, and how to configure them.      Also there are a lot of good examples in Quickstarts on how you could communicate via ftp, http, file, SQL, hibernate, and in addition - what Camel supports.

What I am trying to find is what is the best way to expose an esb service? Should I publish the esb service as a webservice (by having the inXSD and outXSD) or can I use JBR?

Thanks

I would look at the SOAPProxy / HttpGateway combination - see below or see quickstarts like the webservice_proxy_basic one.
