How can I create a Pointer from a byte array ?

try to create a new chunk of memory, fill it with your XML-data and don't forget the terminating zero-byte:

--- snip ------------------------------------------- byte[] xmlData = ...; Memory xmlBuffer = new Memory(xmlData.length + 1); xmlBuffer.write(0, xmlData, 0, xmlData.length); xmlBuffer.setByte(xmlData.length, 0); --- snap -------------------------------------------

now you can pass 'xmlBuffer' as a pointer ...

One of the parameteres of the Pointer.write(...) method is the offset ('offset - byte offset from pointer into which data is copied'). What is this offset? I don't understand the description in the javadoc.

this would be the 'destination offset' ...
