[ZOO-Discuss] Post-Buffer-Request with Java-Client

[Kristof Lange]

Hi again,

i tried my Post-client with the fixed request, but I did an internal 
server error with the given endpoint:

here the request again, perhaps there is an very good hidden mistake in it:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<wps:Execute service="WPS" version="1.0.0"

                 </wps:Input>
                 <wps:Input>
                         <ows:Identifier>BufferDistance</ows:Identifier>
                         <ows:Title>Distance which people will walk to 
get to a playground.</ows:Title>
                         <wps:Data>
                                 <wps:LiteralData>400</wps:LiteralData>
                         </wps:Data>
                 </wps:Input>
         </wps:DataInputs>
         <wps:ResponseForm>
                 <wps:ResponseDocument storeExecuteResponse="false">
                         <wps:Output asReference="true">
                         <ows:Identifier>BufferedPolygon</ows:Identifier>
                         </wps:Output>
                 </wps:ResponseDocument>
         </wps:ResponseForm>
</wps:Execute>

or are the other instances of the zoo-wps, where I could test the request?
Any advise would be great!

best regards
Kristof Lange
