[Geoserver-users] Bug Report in WPS of GeoServer

Hi,

I just wrote a simple WPS client with geotools for GeoServer. I used
the same code in the geotools website:
http://docs.geotools.org/latest/userguide/unsupported/wps.html

I got the following error in WPSFactory():
Exception in thread "main" java.lang.NullPointerException
        at org.geotools.data.wps.WPSUtils.getLiteralTypeFromReference(WPSUtils.java:296)
        at org.geotools.data.wps.WPSUtils.createInputParamMap(WPSUtils.java:183)
        at org.geotools.data.wps.WPSFactory.buildValuesFromProcessDescriptionType(WPSFactory.java:81)
        at org.geotools.data.wps.WPSFactory.<init>(WPSFactory.java:68)
        at au.org.aurin.wps.WPSClient.getCapabilities(WPSClient.java:108)
        at au.org.aurin.wps.WPSClient.main(WPSClient.java:42)

After looking into WPSUtiles class I found out that problem is here:
if (literalData != null) {
                String reference = literalData.getDataType().getReference();
                type = getLiteralTypeFromReference(reference);
}

reference is null, so getLiteralTypeFromReference gives
java.lang.NullPointerException.

I checked the same code with 52N WPS and Deegree WPS, which works fine!
So, I believe that there is a bug in XML of DescribeProcess in
GeoServer as listed below as well:

These are part of XML of Describe process (SimpleBufferAlgorithm in
52N WPS and JTS:buffer in Geoserver WPS)

-------------- in 52N
<LiteralData>
       <ns1:DataType ns1:reference="xs:double"
xmlns:ns1="http://www.opengis.net/ows/1.1&quot;/&gt;
       <ns1:AnyValue xmlns:ns1="http://www.opengis.net/ows/1.1&quot;/&gt;
     </LiteralData>

-------------- in GeoSrrver
<wps:LiteralData>
<ows:DataType>xs:double</ows:DataType>
<ows:AnyValue/>
</wps:LiteralData>

Bahman

From what I can see you're running an old version of GeoServer,

the issue you're facing should be this one:
http://jira.codehaus.org/browse/GEOS-4521

that has been fixed in 2.1.1 release

Cheers

Hi Andrea,

Thanks for your reply.
I installed Geoserver 2.1.1 and WPS-plugin 2.1.1 as well. But still I
have the same problem.
Any idea?

Is the output of DescribeProcess any different than before?
Do you happen to have a small, self contained java program
using the geotools library to connect to the WPS?

Hi,

I am not sure about any changes in the WPS of the GeoServer. This is
my first try to work with GeoServer.
I used the same java code in the geotools website:
http://docs.geotools.org/latest/userguide/unsupported/wps.html

This client works for 52N and Deegree WPS servers. But has this
problem with GeoServer.
I also checked for other processes. It seems that the problem is with
LiteralData, where ComplexData
is ok. For example for Buffer which has one Double and one Geometry,
we got the error for Double number and Geometry is fine.

Thanks for your consideration.

Bahman

Hi,

I am not sure about any changes in the WPS of the GeoServer. This is
my first try to work with GeoServer.
I used the same java code in the geotools website:
http://docs.geotools.org/latest/userguide/unsupported/wps.html

This client works for 52N and Deegree WPS servers. But has this
problem with GeoServer.
I also checked for other processes. It seems that the problem is with
LiteralData, where ComplexData
is ok. For example for Buffer which has one Double and one Geometry,
we got the error for Double number and Geometry is fine.

Thanks for your consideration.

Regards,
Bahman

Hi Andrea,

Thanks for your reply.
I installed Geoserver 2.1.1 and WPS-plugin 2.1.1 as well. But still I
have the same problem.
Any idea?

Is the output of DescribeProcess any different than before?
Do you happen to have a small, self contained java program
using the geotools library to connect to the WPS?

Cheers
Andrea
