I have the following:
HTTP Input --> Compute Node --> HTTP Request Node --> HTTP Reply
In the Compute Node I have the following:
CREATE COMPUTE MODULE TestBuildURL
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
SET OutputRoot = InputRoot;
SET Environment.Destination.HTTP.RequestURL = 'http://test.url.com';
RETURN TRUE;
END;
END MODULE;
|
I am trying to do the above but I want to pass "http://test.url.com" into the HTTP Input node and not have to hard code it in the ESQL. |

Other way that you can try is that following:
SET OutputRoot.HTTPRequestHeader."X-Original-HTTP-URL" = 'http://pmdclbc01/WebServices/serviceCont.asmx'; |

And what is a problem ?
Can you send any data to HTTP input ?
Can you add there this additional data.
What data is sent to HTTP input, SOAP request , standard HTTP GET or HTTP POST ?
Isn't it better to have URL in HTTP Request node based on business data from request rather than let client set this URL ?
I hope I understood you correctly...

I am calling the flow from a Java servlet that passes a SOAP request. The flow is being used as a pass thru for a call to a mainframe web service. I took the WSDL from the mainframe web service and generated a client for it in RAD which creates proxy classes, etc. This generated code somehow converts the object I am passing into a SOAP message and I cannot figure out how to add data to it. Even if I could add the URL to the SOAP message, I wouldn't know how to get at it from the flow.
The servlet calling the flow is determining the URL based upon the environment it is running in (i.e. Dev, Test, Model, etc.). |

Sorry for saying that but after reading this I think this problem is too complicated for you. No offence...

You mean HTTP input URL or mainframe web service URL ?
General question is :
How do you know which mainframe web service URL you should use in your flow ?
If I understand you correctly you want to pass it from this servlet .
How this servlet could determine this mainframe web service URL ?

You are correct that I want to pass the URL of the mainframe web service from the servlet into the flow to be assigned to the RequestURL of the HTTPRequest node. The servlet is reading the URL from a database, which is different depending upon the environment.
Right now I have 5 copies of the same exact flows for Dev, Test, Model, Prod, and Hot fix. The ONLY difference in the flows is the URL for the HTTPRequest node. |

Hm. It is little strange.
It means that from this servlet you have access to Dev, Test, Model, Prod, and Hot fix environment.
Isn't it better to separate environments ? I mean separate servlet, flow and mainframe WS
for Dev, Test, Model, Prod, and Hot fix environment ?
If you really have to add this URL I think the best way here is to add it as additional HTTP header in request from servlet to broker flow and then read it in flow.

The servlet does NOT have access to Dev, Test, etc. environments. When the servlet is run in Dev, it knows that it is in Dev and can then tell the flow the Dev endpoint for the mainframe service. Same goes for Test, Model, etc. It's not important as to how the servlet knows what environment it is being run in, just that it does know.
Assuming I can figure out how to add an addition HTTP header in the request from the servlet, how would I read it in the flow? Any samples?
Thanks. |

It depends on WebService API which you use to send SOAP request.
Sometimes you can do it , sometimes not.

The best way is to send HTTP request in flow to trace node and see message tree. In this tree you will see this header. Then reading it is not very complicated.

You might also want to consider a UserDefinedProperty - if the request URL is static between messages, but not static between deploys.

After researching UserDefinedProperty, it looks like you are suggesting using a JavaCompute node to look up the endpoint from the WebSphere Service Registry and Repository. Is that correct? If so, we are not using such a repository. If that is not correct, could you point me in the right direction of documentation on what you are referring to? |
