Hi, I am new on WBI and I am trying to convert a BLOB message to XML using just the RCD node. I was able to do this from CWF1 to XML so I thought I could do this.
My problem is that when I use the RCD node I get an exception and even though the flow continues I dont get anything in the output (which is ok I wish it complained with something).
When I do BLOB to CWF1 everything is ok but I need to do XML. Maybe this is not possible maybe I just need to use ESQL.
Please let me know if you have any recommendations.
Thanks. |

| Is the BLOB a binary representation of a valid XML-structured message, i.e. includes the XML tag names? |

| No It is not. It is a string coming from a cobol program from the mainframe |

Then why would it parse as valid XML?
You seem to be expecting magic from WBIMB. The training class you should have taken should have told you not to expect magic.
You should strongly consider attending training.
You should spend significantly more time reading the documentation and redbooks before you do much more with this product.

For what it is worth, the WBI MB help has the following to offer on the RCD node:
| Quote: |
The ResetContentDescriptor node does not:
- Change the message content. It changes message properties to specify the way in which the bit stream is parsed next time that the parser is invoked.
- Convert the message from one format to another. For example, if the incoming message has a Message Format of XML and the outgoing Message Format is CWF, the ResetContentDescriptor node does not do any reformatting. It invokes the parser to recreate the bit stream of the incoming XML message, which retains the XML tags in the message. When the message is reparsed by a subsequent node, the XML tags are invalid and the reparse fails.
|
The actual help has quite a bit of detail on how the node works and what it does. You might want to check it out. |

I got it to work.
I receive a blob message and then I have a compute node to determine what to do using labels and then after the label I have an RCD node to change parser to CWF1 using a messageset that has only MRM physical property then I put a mapping node that has the source from this message set and then I have as target a message that has been defined in a different message set with XML physical properties and that's it, magic from WBI I have my output message formated in XML.
Thank you guys. |
