Hi
I am unable to understand from the documentation, what is the relation between soapNodesUseEmbeddedListener and HTTP Nodes.
What appears to me (after repeated trials and now a re-produsable series of steps), is the following :
Create an Integration Service, this will generate a message flow with SoapInput & SoapReply
2. Complete the sub-flows, to test a PassThrough node is sufficient, this makes this an Echo service.
3. Add a second message flow, this time taking in HTTPInput followed by an HTTPReply
4. Deploy the integration service to a newly created execution group
5. The SOAP interface will work, but the HTTP interface will fail with the following error
| Code: |
Exception. BIP2230E: Error detected whilst processing a message in node 'Test.HTTP Reply'. : /build/slot2/S000_P/src/WebServices/WSLibrary/ImbWSReplyNode.cpp: 968: ImbWSReplyNode::evaluate: ComIbmWSReplyNode: Test#FCMComposite_1_2 BIP3745E: The node ''Test.HTTP Reply'' received a message with an invalid 'HTTP' 'RequestIdentifier'. : /build/slot2/S000_P/src/WebServices/WSLibrary/ImbWSReplyNode.cpp: 882: ImbWSReplyNode::evaluate: ComIbmWSReplyNode: Test#FCMComposite_1_2 BIP3740E: An attempt was made to use an invalid 'Unknown' message identifier '414d5120494239514d4752202020202042701a540d001320'. : /build/slot2/S000_P/src/WebServices/WSLibrary/ImbSOAPHandleManager.cpp: 1899: ImbSOAPHandleManager::retrieveInputNodeMessageHandle: :

6. Change the execution group to use the broker wide listener for SOAP Nodes, & restart the broker
7. Both the SOAP & the HTTP interfaces will work!.
If I change the soapNodesUseEmbeddedListener to true again, I can reproduce the behaviour, so I suppose this is the expected behaviour.
But I haven't been able to find anything about this in the documentation, what's really going on here?
I bumped into this, when I started using the Mobile Pattern that's shipped with the toolkit, the pattern requires a SOAP service, and modifies the project by adding a HTTP message flow. It adds a lot of stuff to for JSON2XML & XML2JSON etc...but the HTTP flow keeps failing with the error that I've described above till I change the EG property.
Given that this is such an important step, I suppose the documentation could be a bit explicit about this, I guess many folks would have faced this scenario..
Am I on the right track here or am i making some mistake?

Haven't tried it myself but I would expect that you are mistaken.
By default the HTTP Listener uses the broker wide Listener and the SOAP listener the execution group (Integration Service) listener.
What I suspect might be happening is that you do not take care of keeping the identifiers separate in the Local Environment and restoring at the appropriate moment...
Have fun

Hi
An update, this definitely seems to be either the expected behaviour (requiring the documentation to change) or a bug..
I've shared the sample code https://github.com/quantiguous/iib_samples , in case you'll have sometime to look.
What I've noticed is that as long as the SoapInput & HTTPInput are using the sample listener (either embedded or broker-wide), the HTTP Endpoint works, but if the SoapInput & HTTPInput use different listeners , the HTTP Endpoint stops working. (The Soap endpoint always works!).
Any ideas?

And you've verified that the port for the HTTPListener that did not work is correct and not already taken?

Hi
I deleted all EG's and restarted the broker .
I created a new EG And deployed the integration service, soap worked ( on port 7800 , the default ), http have back an error reply ( on port 7080 , the default ).
I set soapNodesUseEmbeddedListener to false, restarted the broker , soap worked ( on port 7080 ) and http worked ( port 7080 )
I set soapNodesUseEmbeddedListener to true & httpNodesUseEmbeddedListener to true , restarted the broker , soap worked ( port 7800 ) and http worked ( port 7800 ).
There's one more combination, but I did not try that .
The code was generated, first by (a) new integration service, this generates the soap flow, and 4 subflows for the business logic, I changed only the subflows , I did not touch the main flow, and then by (b) new pattern instance of mobile pattern, this created a second flow in the same project, this one uses http nodes, and calls the same sub flows that were created in the first step.
The sub flows do not have any soap or http nodes, in the sample I put PASSTHRU nodes in the subflows that are meant for exception handling ( timeout, catch and failure ) and one simple compute node to copy the input to the output ( to echo ).
If you look at the exception it mentions a value for the reply identifier, this value is infact correct, I can see it in the trace as well..
Any ideas?

Or vice versa ( a message receive by the HTTPInput node to the SOAPReply node)
