[Pywps-devel] [Pywps-commits] PyWPS 3.0-svn examples Problem Fix and more

[Jachym Cepicky]

Hi,

this seems to tbe between various GRASS versions (maybe some v.buffer
change between GRASS 6.4 and 6.2) and PyWPS (I thing, I updated the
examples up to grass 6.3) -- feel free to fix the example processes,
so the work for you.

The second problem: By default, (Py)WPS returns resulting data as
ComplexValue output type. It appears, that embeding binary data (PNG
file in this case) directly into XML files even in CDATA section does
not provide valide XML.

All you have to do is to call the request of the process execution
with definition for the process outputs and define, that the output
map files should be returned back as reference, examples:

for HTTP GET:

...&responsedocument=[buffer=@asreference=true]

for HTTP POST:

......
 </wps:DataInputs>
        <wps:ResponseForm>
                <wps:ResponseDocument wps:storeExecuteResponse="true"
wps:status="frue">
                    <wps:Output wps:asReference="false">
                        <ows:Identifier>buffer</ows:Identifier>
                    </wps:Output>
                    <wps:Output wps:asReference="true">
                        <ows:Identifier>bufferRaster</ows:Identifier>
                    </wps:Output>
                </wps:ResponseDocument>
        </wps:ResponseForm>
