Hi All,
I am getting a 'Structure id mismatch at offset' exception from 'ImbMqmdParser::refreshElementsFromBitStream' parser in the below code when the control reaches getGlobalEnvironment() method:
public void evaluate(MbMessageAssembly contact admin) throws MbException {
MbMessage inMessage = contact admin.getMessage();
//get the terminals
MbOutputTerminal out = getOutputTerminal("out");
MbOutputTerminal alt = getOutputTerminal("alternate");
//create output message
MbMessage outMessage = new MbMessage(inMessage);
copyMessageHeaders(inMessage, outMessage);
MbMessage outEnv = new MbMessage(contact admin.getGlobalEnvironment());
MbMessage outLEnv = new MbMessage(contact admin.getLocalEnvironment());
//build output assembly
MbMessageAssembly outAssembly = new MbMessageAssembly(contact admin,outLEnv,outEnv,outMessage);
//generate monitoring string
MonitoringData data = new MonitoringData();
MbElement rootElement = outAssembly.getGlobalEnvironment().getRootElement();
// Get the Monitoring Data Field Names from the Environment Variables
MbElement componentName = rootElement.getFirstElementByPath("/Variables/LoggingInfo/componentName");
String COMPNAME = (String)componentName.getValue();
.
.
.
******Please find the exception tree as given below:
(0x01000000):RecoverableException = (
(0x03000000):File = 'F:\build\S600_P\src\DataFlowEngine\ImbDataFlowNode.cpp'
(0x03000000):Line = 616
(0x03000000):Function = 'ImbDataFlowNode::createExceptionList'
(0x03000000):Type = 'ComIbmJniNode'
(0x03000000):Name = 'P10_ODIN_FLOW1#FCMComposite_1_7.P10_ODIN_LogMsg_SUBFLOW#FCMComposite_1_2'
(0x03000000):Label = 'P10_ODIN_FLOW1.P1.LogMonitorMsg'
(0x03000000):Catalog = 'BIPv600'
(0x03000000):Severity = 3
(0x03000000):Number = 2230
(0x03000000):Text = 'Node throwing exception'
(0x01000000):ParserException = (
(0x03000000):File = 'F:\build\S600_P\src\DataFlowEngine\ImbMqmdParser.cpp'

(0x03000000):Catalog = 'BIPv600'
(0x03000000):Severity = 3
(0x03000000):Number = 2162
(0x03000000):Text = 'Structure id mismatch at offset'
(0x01000000):Insert = (
(0x03000000):Type = 2
(0x03000000):Text = '0'
*****Has anybody come accross this kind of scenario, if so then please help me out in solving this

I think there's a problem here:
| Code: |
//create output message
MbMessage outMessage = new MbMessage(inMessage);
copyMessageHeaders(inMessage, outMessage); |
The first statement is essentially equivalent to ESQL "Set OutputRoot = InputRoot;". That includes copying the message headers.
It's likely that the subsequent call to copyMessageHeaders() is appending a duplicate set of headers after the message body, and it's likely that that's the cause of the MQMD ParserException.
There's also a problem here:
| Code: |
//build output assembly
MbMessageAssembly outAssembly = new MbMessageAssembly(contact admin,outLEnv,outEnv,outMessage); |
The expected arguments in this MbMessageAssembly constructor are:
| Code: |
| MbMessageAssembly(contact admin, localEnvironment, exceptionList, message); |
The use of "globalEnvironment" as an argument is deprecated. |
