I searched for http on this web and got more helpfull information. I used IA81 nettool to post the messages. If it is request and reply then i have no issues.
But i am trying to implement in the following scenario,
HttpInput --> Compute (XML formatting) --> MQ Out1/MQOut 2
MQ Out1 to maintain the state and out2 for actual backend processing.
MQ Input (backend send the responce) --> MQget (get the state message) -->compute (xml formatting) --> Http Reply
How to send the state info to MQ Out1 and how can we send the formatted message to MQ Out2?
I am looking the document. Mean while if you have any suggestion will be appriciated.
thanks,
Siva |

I am sorry..I saw that sample again.
I need to use compute node twice, one for service and other for state. Let me try.
Thanks,
Siva |

Have you posted all your ESQL, as the error message is generated because a datasource name was not found when used in a compute node, and I didn't notice any DB operation in your ESQL. Have you specified a DataSource that is invalid on your compute node?

Hi MGK,
Yes that's all my esql.
I did not specify datasource with in the compute node properties. Do i need to include any thing in the ESQL?
I am just sending an xml message and receive same xml (in feature i can use first compute1 for formatting). Please help me out what i need to setup.
thanks,
Siva |

Sorry for too many posts...
As an Admin it is very difficult to go through all development documnet for our http pilot. I spent two full days to get minimum skill set to develop a flow.
We are doing Http Pilot testing for legacy systems.
Flow1:
HttpInput --> Compute --> MQOutput (Qmgr and queue names are empty, "Advanced" select messageid, Corr ID,Message context to setall and select request option with reply to Q as HTTP.LEGACY)
MQInput(HTTPOUT) --> Compute1 --> HttpReplay
Flow2 (for legacy):
MQInput (HTTP.LEGACY)-->Compute(LegacyWMQIFlow_compute1)-->MQOut (HTTPOUT).
Message Domain for MQInput node is XML.
Here is the ESQL for all 3 compute nodes,
CREATE COMPUTE MODULE WebServiceInputTestFlow_Compute
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
CALL CopyEntireMessage();
RETURN TRUE;
END;
CREATE PROCEDURE CopyEntireMessage() BEGIN
SET OutputRoot = InputRoot;
SET OutputRoot.HTTPInputHeader = null;
CREATE NEXTSIBLING OF OutputRoot.Properties domain 'MQMD';
SET OutputRoot.MQMD.StructID = MQMD_STRUC_ID;
SET OutputRoot.MQMD.Version = MQMD_CURRENT_VERSION;
SET OutputRoot.XML.Data.HTTPContext =
CAST(InputLocalEnvironment.Destination.HTTP.RequestIdentifier AS CHARACTER);
END;
END MODULE;
CREATE COMPUTE MODULE WebServiceInputTestFlow_Compute1
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
CALL CopyEntireMessage();
RETURN TRUE;
END;
CREATE PROCEDURE CopyEntireMessage() BEGIN
SET OutputRoot = InputRoot;
SET OutputLocalEnvironment.Destination.HTTP.RequestIdentifier =
CAST(InputRoot.XML.Data.HTTPContext AS BLOB);
SET OutputRoot.MQMD = null;
END;
END MODULE;
CREATE COMPUTE MODULE LegacyWMQFlow_Compute
CREATE FUNCTION Main() RETURNS BOOLEAN
BEGIN
CALL CopyEntireMessage();
RETURN TRUE;
END;
CREATE PROCEDURE CopyEntireMessage() BEGIN
SET OutputRoot = InputRoot;
SET OutputRoot.XML.Data = 'NewData';
END;
END MODULE;
Using NetTool to post the message.
XML message as shown below,
<HTTPTest>
<URL>http://localhost:7080/httppost</URL>
<InputData>
<Data>Test</Data>
</InputData>
<OutputData>
<Data/>
</OutputData>
</HTTPTest>

The input node 'WebServiceInputTestFlow.HTTP Input' detected an error whilst processing a message. The message flow has been rolled-back and a fault message returned to the requesting client. Following messages will indicate the cause of this exception.
Check the error messages which follow to determine why the exception was generated, and take action as described by those messages.
I am not sure is it a problem with the nettool or my code/node properties. Please let me know if you find any thing wrong. Can i get any samples for this type of application(not MRM)?
Thanks,
Siva |

The key part of the error message is:
| Quote: |
| There should be one, and only one, top level element of type Element or EmptyElement and this is not the case for the current message. |
This is caused by the lines:
| Code: |
SET OutputRoot = InputRoot;
SET OutputRoot.XML.Data = 'NewData'; |
and:
| Code: |
| SET OutputRoot.XML.Data.HTTPContext = ... |
According to your input message you posted it should be:
| Code: |
SET OutputRoot = InputRoot;
SET OutputRoot.XML.HTTPTest.Data = 'NewData'; |
and:
| Code: |
| SET OutputRoot.XML.HTTPTest.Data.HTTPContext = ... |

How to remove http Identifier from the http reply?
Input: <HTTPTest>
<URL>http://localhost:7080/httppost</URL>
<InputData>
<Data>Test</Data>
</InputData>
<OutputData>
<Data/>
</OutputData>
</HTTPTest>
OutPut:
HTTP/1.1 200 OK
Content-Type: text/xml;charset=utf-8
Content-Length: 252
Date: Thu, 25 May 2006 04:24:45 GMT
Server: Apache-Coyote/1.1
Connection: close
<HTTPTest>
<URL>http://localhost:7080/httppost</URL>
<InputData>
<Data>Test</Data>
</InputData>
<OutputData>
<Data/>
</OutputData>
<Data><HTTPContext>X'414d51205346425f574d4220202020205341744420001e0c'</HTTPContext></Data></HTTPTest>
But i am looking for the output,
<HTTPTest>
<URL>http://localhost:7080/httppost</URL>
<InputData>
<Data>Test</Data>
</InputData>
<OutputData>
<Data/>
</OutputData>
</HTTPTest>
Also i tried different xml with the following esql,
SET OutputRoot.XML.SEC.MESSAGEID = InputRoot.XML.SEC.MESSAGEID;
SET OutputRoot.XML.SEC.OPERATORID = InputRoot.XML.SEC.OPERATORID;
SET OutputRoot.XML.SEC.PASSWORD = InputRoot.XML.SEC.PASSWORD;
i couldn't make it here.
If you use i/p -->compute-->o/p then it works. |

Hi,
Instead of solving the previous problem by reconstructing the ESQL as said by mgk, alternative method is to modify HttpRequest node advance property..
set request message location in tree = InputRoot.XML.HTTPTest.InputData
set response message location in tree = OutputRoot.XML.HTTPTest.OutputData
Uncheck the the boxes "use whole input mesaage as request" and "Replace input message with webservice response" and check the rest boxes.

Hi,
Do i need to use httpRequest for that?
I have ony HttpInput and HttpRepy in the picture.
Some reason the output come up with httpcontext info.
Do i need to use Copy header instead of copy entire message.
You can see my Esql and fow logic from the above post. |

yes for implementing that you need a Httprequest node. I thought you are also using MB for webservice client. You can ignore the part.
If you don't want to include that in your out put xml ,set it to null.
| Code: |
SET InputRoot.XML.HTTPTEST.Data.HTTPContext = NULL;

Sorry, typing mistake...the esql will be SET OutputRoot..... rather than InputRoot.
