JSR181 Endpoint question

[Seguy <ca...@gmail.com>]

Hi,

My team is involved in a project that has chosen Servicemix as our ESB
platform. We gonna develop our components as endpoints and we want to
invoke different methods/operations for each endpoint. At a first
glance, it seems that the JSR181 component could fit to our idea.

It seems that the invocation of a specific method is done by the
JSR181 endpoint via a soap message send to XFire:

<?xml version="1.0" encoding="UTF-8"?>
                <e:Envelope
xmlns:e="http://schemas.xmlsoap.org/soap/envelope/">
                    <e:Body>
                        <method-name>
                            <aRequest>
                            	... 	  
                            </aRequesty>
                        </method-name>
                    </e:Body>
                </e:Envelope>
                
Is this idea correct?

The other idea we had was to implement a "lightweight component pojo".
If we use such a lw-pojo and want to call its different operations, do
we have to use the onMessageExchange method of the lw-pojo? For instance,
we could extract the operation from the MessageExchange and invoke the
method/operation in our onMessageExchange-implementation using
reflection from this lw-pojo.

Are there any other ways to invoke specific methods/operations from an
endpoint? Are there any examples of how to fulfil this task ?

No.
The jsr181 component expect a non-soap message.
Soap is handled by BCs (servicemix-http for example).

Yeah, if the jsr181 component does not fit your needs, this is currently
the easiest path to go.   You could also take a look at the
org.apache.servicemix.components.reflection package, but these components
do not use the xml payload, so it may be difficult to bridge with other
components.

The jsr181 component also has a proxy, but it currently requires
a WSDL for the target endpoint, so it may be of a limited use currently.
