Hi Folks,

I am getting "Output Message Contains no Data Exception" Please help me out.

Here is the EXception List:

-- Exception List
(
(0x1000000)RecoverableException = (
(0x3000000)File = 'F:\build\S210_P\src\DataFlowEngine\ImbMqOutputNode.cpp'
(0x3000000)Line = 715
(0x3000000)Function = 'ImbMqOutputNode::evaluate'
(0x3000000)Type = 'ComIbmMQOutputNode'
(0x3000000)Name = 'dafad458-f900-0000-0080-ea3993443c2a'
(0x3000000)Label = 'CCP_Request.Response'
(0x3000000)Text = 'Caught exception and rethrowing'
(0x3000000)Catalog = 'WMQIv210'
(0x3000000)Severity = 3
(0x3000000)Number = 2230
(0x1000000)RecoverableException = (
(0x3000000)File = 'F:\build\S210_P\src\DataFlowEngine\ImbMqOutputNode.cpp'
(0x3000000)Line = 576
(0x3000000)Function = 'ImbMqOutputNode::evaluate'
(0x3000000)Type = 'ComIbmMQOutputNode'
(0x3000000)Name = 'dafad458-f900-0000-0080-ea3993443c2a'
(0x3000000)Label = 'CCP_Request.Response'
(0x3000000)Text = 'Message contains no data'
(0x3000000)Catalog = 'WMQIv210'
(0x3000000)Severity = 3
(0x3000000)Number = 2617
)
)
)

Here is the ESQL Code

DECLARE Stmt CHAR;
DECLARE CARD INTEGER;

SET Stmt = Environment.Variables.Query.Statement;
--SET Environment.Variables.Statement = Stmt;
IF ((Stmt IS NOT NULL)) THEN
EVAL ('SET Environment.Variables.Query.Response[] =
(SELECT T.* FROM Database.T1 AS T '||' '||Stmt||')');

SET CARD = CARDINALITY(Environment.Variables.Query.Response[]);
DECLARE Pnumber CHAR;
SET Pnumber = CAST (Environment.Variables.Query.Response[1]."OMCH_CLM_NB" AS CHAR);
SET OutputRoot.XML.Query.Response = Environment.Variables.Query.Response[1]."OMCH_CLM_NB";
END IF;

Here is the Text from the User Trace...

2003-12-21 19:22:12.194999 319 RecoverableException BIP2230E: Error detected whilst processing a message in node 'CCP_Request.Response'.
The message broker detected an error whilst processing a message in node 'CCP_Request.Response'. An exception has been thrown to cut short the processing of the message.
See the following messages for details of the error.
2003-12-21 19:22:12.194999 319 RecoverableException BIP2617E: Output message is empty; output node 'CCP_Request.Response'.
The MQSeries output node 'CCP_Request.Response' has received a message to write to an MQSeries output queue, but the message appears to be empty. This error may be generated when 1) there is no MQMD and no message content in the output bitstream (there really is no data) or 2) there is no MQMD and the size of the message content is less that the size of the MQMD (it appears there is no content). This situation can occur when a output message is built incorrectly using the Compute node.
Check the message flow to determine whether the message is being built correctly. If not, correct the problem and redeploy the broker.

I checked it and could not find the problem . Please help me out.

Thanks,
