In the process you attached, the "input" variable is being initialized, effectively being set to an empty string. It is then referenced, but it's already been wiped out, hence the blank response. Remove the first two "copy" operations from your "assign" activity and it should be closer to working.
In your process, the input variable is populated/initialized by the "receive" activity in the beginning of the process, with the data "sdfgsdfg", from the incoming message. It's only the output variable that _you_ need to initialize, since it is an empty xml document. If you're looking for a minimal echo bpel process, I have attached one below. The process below was created with the Eclipse BPEL Designer and is very similar, just a simpler way to accomplish what you're after. If you notice, I didn't have to initialize the output variable. It may not have been clear from earlier emails, but you only have to initialize vars if you're going to copy a value into a section of a message that is deeper than the node you're specifying with "message" and "part". I realize that explanation may or may not help. I would say review the "Assign" section of the BPEL spec[1]. I had to read it several times and admit that I still get it all. Let us know if it still doesn't work.
