The truth is always out there :-)

Use JNI to get the char* into a string (should be possible but i've 
never used JNI)

Then write a custom generator that does something like the following in 
generate()

String myString = myjnifunction.getData();
XMLReader parser = 
XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");
parser.setContentHandler(this.contentHandler);
parser.parse(new InputSource(new BufferedInputStream( 
      new ByteArrayInputStream(mystring.getBytes()))));

Sorry but I fail to see how soap gets into this picture all of a sudden.

Above code can generate MB's of data extremely fast.
