As to Java, I'm the worst person in the world to advise you.
I'm slightly alarmed to see something called "inputXml" being parsed with DFDL.

DECLARE inputXml CHARACTER CAST(InputRoot.BLOB.BLOB AS CHAR CCSID 1208);
inputxml is the blob message |

| Why are you trying to parse XML with the DFDL parser? |

I don't think you're going to get much from us until you explain this apparently inexplicable decision.

The Java user-defined node API describes a method that, for a given element, will create another element as its last child from a bitstream.

Setting aside the question of why a variable called "inputXml" would contain a presumably non-XML message, why would the message flow CAST a perfectly good BLOB to CHARACTER before passing it to the PARSE clause of a CREATE statement? |

My guess is to make it readable by a human when running in debug mode...
