Re: concurrent execution in servicemix
Hi ,
As per your suggestion i have changed all the inonly exchanges to inout and
sending them in an asynchronous fashion.
But, now the concurent execution is lost and all the 4 requests are being
send one after one(i.e after getting resoponse from one request only the
subsequent request is being sent)
Can you please let me know how to achieve parallel execution in this way. I
uploaded the JBI component java file also to this.

If you use send and not sendSync, they will be sent and processed concurrently.
You may even receive a response before having sent the 4 requests...
You should be able to see that easily if you put a sleep in your lightweight
components.
Btw, the lightweight components are deprecated, so you'd better use
servicemix-bean instead.
