Hi WMB Developers,
I have parsed records from xml to BLOB using JCN. When I debug the flow I have seen the message in output structure,but in output queue i got 0length of data.
Here is my code
MbElement rootElement=inMessage.getRootElement().getLastChild().getLastChild();
List<MbElement> li=(List<MbElement>)rootElement.evaluateXPath("*");
MbMessage outMessage = new MbMessage(inMessage);
MbMessageAssembly outAssembly = new MbMessageAssembly(contact admin,outMessage);
outMessage.getRootElement().getLastChild().detach();
MbElement blob=outMessage.getRootElement().createElementAsLastChild(MbBLOB.PARSER_NAME);
blob.createElementAsLastChild(MbElement.TYPE_NAME_VALUE,"Records",li.toString().getBytes());

| Review the BLOB parser again. |

You are building the wrong tree. The BLOB parser does not work the way you are trying to use it.
Go learn how the BLOB parser works, and then fix your code to build the right tree.
Go, read, think, try, repeat. |

It's this line
| Code: |
| blob.createElementAsLastChild(MbElement.TYPE_NAME_VALUE,"Records",li.toString().getBytes()); |
That builds the WRONG TREE.
It will take you FAR less time and be FAR MORE VALUABLE if you simply GO to the Info Center and READ about the BLOB parser.
Why do you refuse to do this? |

String myMsg = "The Message Data";
MbElement outRoot = outMessage.getRootElement();
// Create the Broker Blob Parser element
MbElement outParser = outRoot.createElementAsLastChild(MbBLOB.PARSER_NAME);
// Create the BLOB element in the Blob parser domain with the required text
MbElement outBody = outParser.createElementAsLastChild(MbElement.TYPE_NAME_VALUE, "BLOB", myMsg.getBytes()); |

98% there. Think about CCSID and you'll get the next 2 %!

| I suggest that you read the JavaDoc for java.lang.String.getBytes(). |

This code working properly but I have not get data in the output queue
MbMessage outMessage = new MbMessage(inMessage);
MbMessageAssembly outAssembly = new MbMessageAssembly(contact admin,outMessage);
outMessage.getRootElement().getLastChild().detach();
MbElement blob=outMessage.getRootElement().createElementAsLastChild(MbBLOB.PARSER_NAME);
MbElement bl1=blob.createElementAsLastChild(MbBLOB.ROOT_ELEMENT_NAME);
bl1.createElementAsLastChild(MbElement.TYPE_NAME_VALUE,"Record",fName.getValueAsString().getBytes()); |

This line will never produce any output under the BLOB parser.
EVER. |

It may be "working properly", but it is not good code. Did you read that JavaDoc? |
