Question from a primer:

we have developed an IDOC parser/generator, which runs fine in standalone mode. We want to use it inside a JAVA plugin for WMQI. For converting the native IDOC string, that comes into the plugin in BLOB-format, we must extract these characters out of the MbMessage element, process it to its XML-representation and finally put the result into a new Message as XML. The way from IDOC/XML to native IDOC works inversely. The MbMessage must provide the body in XML-format and we want to put BLOB to the output terminal after converting in the IDOC generator.

Put into one question: How can I access the whole BLOB of the body?

Thanks for help

Have you read the Programming Guide? It tells you how to access the contents of your message body from a Java node.

Here's a quick example:
Code:
MbElement rootElement = assembly.getMessage().getRootElement();
MbElement blobElem = rootElement.getFirstElementByPath("./BLOB/BLOB");
byte[] blobData = (byte[])(blobElem.getValue());

This is untested code, and there's probably a better way to get the bytes from the blob field.
