EIP help

[eamdwyer]

Hi

I've been looking at the bridge example which shows how a request can be sent through an EIP pipeline from a HTTP component to an XSLT component and then on to a JMS component. The example uses a http binding component that has its defaultMep set to in-only.

Can an EIP only  bridge from in-only MEPs?

I've tried to modify the cxf-ws-security example to bridge from the cxf-bc to a component I created myself but am getting the follwing error when I invoke on it. Is it possible to bridge from an InOut MEP?

That is correct, the servicemix-eip pipeline will only bridge from an InOnly or a RobustInOnly MEP to a InOut MEP. See the documentation for the pipeline pattern.

You could try using the Camel service unit instead as that can handle different mesage exchange patterns more seamlessly.

e.g.

from("something").
  to("xslt:com/acme/foo.xsl").
  to("activemq:MyQueue");

which would work for an InOut or InOnly.
