Unable to discover service endpoint.

[ericnygma <pr...@gmail.com>]

Hi,

My aim is to write to a File using the File BC.

1)I followed the instructions on
http://incubator.apache.org/servicemix/24-beginner-configuring-the-servicemix-file-su.html
to create the SU for the service-file BC. Also wrote an SA and deployed onto
Servicemix.

2) The xbean.xml of the SU looks as :
<beans xmlns:file="http://servicemix.apache.org/file/1.0"
       xmlns:sm="http://servicemix.apache.org/config/1.0"
       xmlns:myns="http://hellothere.com/jbi/"> 
      <file:sender service="myns:myFile" 
             endpoint="myFile"
             directory="file:D:/space/svcmix/trial/" >
                 <sm:marshaler>
    <sm:defaultFileMarshaler>
      <sm:fileName>
        <sm:xpathString xpath="concat('testing', '.xml')"/>
      </sm:fileName>
    </sm:defaultFileMarshaler>
  </sm:marshaler>
    </file:sender>
</beans>

3)Because of the above xbean.xml , I assume the File SA can be discovered in
the JBI container with the QName : {http://hellothere.com/jbi}myFile.

4)I have written an SE and deployed it into servicemix. The SE code has
something as below to discover ServiceEndpoints.
ServiceEndpoint serviceEndpoint =
getServiceUnit().getComponent().getComponentContext()
                       .getEndpoint(new
QName("http://hellothere/jbi","myFile"),myFile );

5)I find that the above serviceEndpoint is NULL, its unable to find the File
SU.
I intend to use this variable further down in
messageExchange.setEndpoint(serviceEndpoint); to send a message to that
endpoint, with the aim of writing the message content.

Can someone please advice on the error in my code/SU's xbean.xml.I am not
able to figure out how to accomplish this.

Thanks for the help
Eric.

Well, I don't see any errors in your code. In fact, I've used the
ComponentContext.getEndpoint() method myself to locate endpoints and
it has worked well. I recommend bringing up jconsole to look at the
endpoints in the ServiceMix JMX domain to make sure that the endpoint
is actually deployed and available via JMX.
