Currently, the initialization for your variable is:
<bpel:copy>
<bpel:from>
<bpel:literal xml:space="preserve">
<ns0:submitDocument xmlns:ns0="
http://webservice.adapter.xynapse.nubizz.de/xsd";
xmlns:xsi="
http://www.w3.org/2001/XMLSchema-instance";>
</ns0:submitDocument>
</bpel:literal>
</bpel:from>
<bpel:to variable="xynapseRequest" part="parameters"/>
</bpel:copy>
whereas the literal should be at least,
<ns0:submitDocument xmlns:ns0="
http://webservice.adapter.xynapse.nubizz.de/xsd";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
<ns0:pDocType/>
<ns0:pDocument/>
</ns0:submitDocument>
In order to select the nodes in your <to> clause. Eclipse doesn't fully
initialize the variables for you.
