[Geoserver-users] WFS GetFeature using Post Method => java.lang.NullPointerException

Jeremy_DERRAC · July 16, 2007, 3:28pm

Hi,
I'm trying to get just one attribute of a designed feature but i'm
getting a "java.lang.NullPointerException".
I can't see what's wrong....
Ask for more details if you need.

Thanks !

Here is my request through post:

<wfs:GetFeature xmlns:wfs="http://www.opengis.net/wfs" service="WFS"
version="1.0.0" xmlns:gml="http://www.opengis.net/gml"
xmlns:ogc="http://www.opengis.net/ogc"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <wfs:Query wfs:typeName="icia:batiment_prive">
    <ogc:PropertyName>icia:qualite</ogc:PropertyName>
    <ogc:Filter>
      <ogc:FeatureId fid="batiment_prive.26"/>
    </ogc:Filter>
  </wfs:Query>
</wfs:GetFeature>

Here is the answer:

<?xml version="1.0" ?>

</ServiceExceptionReport>

Here is the GeoServer Log (Too long for the mail so its linked):

Jeremy: which version of GeoServer are you using. I may be wrong but I think this issue was just recently fixed. Andrea can you confirm that this is the dreaded no default geometry problem?

Hmm... this dataset is not geometryless, yet I think that fix I made
covers this case too. I bet your source is a shapefile without .prj file, or a postgis table with a SRS declared as -1 (unknown)?

Can you grab a 1.5.2-snapshot from http://geo.openplans.org/nightly/1.5.x/ and give it a spin?

Cheers
Andrea

Jeremy_DERRAC · July 17, 2007, 8:37am

I downloaded http://geo.openplans.org/nightly/1.5.x/geoserver-1.5.x-071607-bin.zip
(the latest in the displayed list)
Moved my geoserver/ to geoserver.old/
Extracted the new one to geoserver/
Deleted geoserver/data_dir
Copied geoserver.old/data_dir to geoserver/data_dir
Started geoserver/bin/startup.bat

On admin page it still display 1.5.1 I'm i doing something wrong?

Anyway i tested it again, its the same problem :

req:
POST /geoserver/wfs? HTTP/1.0
User-Agent: GrfMapViewer
Content-Length: 407

Hem, no, we just did not change the labels.

Anyway i tested it again, its the same problem :

Sigh, then I don't know what's going on. Can you dump your data
to a shapefile and sent it to me by private mail along with
the GetFeature request you're issuing? I'll try to reproduce your
problem on my PC and eventually fix it.

Cheers
Andrea

Andrea_Aime3 · July 17, 2007, 12:54pm

Jeremy,
thanks for the sample data. I isolated the issue and hopefully fixed it.

You can check if things are going to work with you by grabbing
today's nightly, which should be out sometimes during the late
afternoon here: http://geo.openplans.org/nightly/1.5.x/

Let me know how it goes.
Cheers
Andrea
