Hi,
We are working on Web Services on MB v 6.1.
We have a requirment where SOAPInput node need to handle call to web service supporting multiple operation .We need to follow different message processing path depending upon the operation specified by client.
We thought of using Routing function provided by SOAPExtract node . SOAPInput --> SOAPExtract and this node will route(at runtime) to different labels depending on operation specified in the reseuest. But, we are not sure how extract node takes decision of routing messages to different nodes. Because,examples from sample galary show that the string used after prefix ('ws_' in the example) need not match to the operation name in the WSDL.So,we are in doubt how Extrat node routes to different lables in that case.
Can you some one throw some light on this.
Thnaks in advance |

Hi.
The 'ws_' is just a prefix added by default by the SOAPExteact node when generating a flow from WSDL. You can change this on the extract node if you want to.
However, you can also wire a SOAPInput node directly to a RouteToLabel node if you wish as the SOAPInput node adds all the necessary routing information to the LocalEnvironment automatically (which will allow routing to a label node with the WSDL Operation Name). This allows you to continue to use the SOAP parser for things like attachments if you need to.
Regards,

Hi mgk,
Thanks inoformation.
I still have a doubt.May be I will try to expain it with scenario.
Consider a case where I have 3 operation ,A,B,C ,linked to a web service XYZ. Say,I configure Extract node with route to prefix 'ws_'. In this case I need to have 3 label nodes as there are three operations.
Now,my question is what should i put in the 'Label Name' property of each Label node ? As i understand it should be like 'ws_?'. But then what should go for question mark ?
In the example that i was following from toolkit sample galary (it is single operation example), they have mentioned 'ws_(firstElementOFSoapBody)'. But at the same time I can see in debugger that routing information in LocalEnvironment is set to 'Operation Name' that is set in properties of the SOAPInput node. So I am confused about how the routing is taking place in this case  |

If you look at the properties of the SOAPInput node, you can see that is also has the ability to set a "label prefix". If you place (for example) 'ws_' in there then the routing information in the LocalEnvrionment after the SOAPInput node will contain 'ws_<operationName>' where the <operationName> came from the SOAPAction or WSAAction (if WSA is or a SOAPAction was used) or the <firstChildOfBody>.
