Hi Feel free to create a ticket if you would like such a feature in Camel with the mina being able to correlate. Maybe there is something we can do. But yet again JMS is much better for reliable messaging, but sometimes low level TCP could be feasible instead if bringing in a JMS broker in the server farm.
You can also try other remoting protocols such as RMI, file based :), XMPP, HTTP, REST, SOAP etc. On Tue, Mar 10, 2009 at 3:30 PM, Claus Ibsen <claus.ib...@gmail.com> wrote: > On Tue, Mar 10, 2009 at 3:08 PM, mam1 <dbra...@novator.com> wrote: >> >> >> >> Claus Ibsen-2 wrote: >>> >>> On Mon, Mar 9, 2009 at 6:21 PM, mam1 <dbra...@novator.com> wrote: >>>> >>>> Hi. >>>> >>>> I have a multithreaded environment using Camel's Mina component with >>>> Spring >>>> Remoting as following: >>>> >>>> <camel:camelContext> >>>> <camel:proxy id="test_client" >>>> serviceInterface="a.b.c.TestService" >>>> serviceUrl="direct:test_service"/> >>>> >>>> <camel:route id="test_service_mina_route"> >>>> <camel:from uri="direct:test_service"/> >>>> <camel:to >>>> uri="mina:tcp://localhost:8000?textline=false&minaLogger=true&timeout=100000&lazySessionCreation=true&sync=true&exchangePattern=InOut&transferExchange=true"/> >>>> </camel:route> >>>> </camel:camelContext> >>>> >>>> >>>> I am getting unexpected results.
