[Geoserver-users] WFS Exception

GeoServer GeoServer User
1

Dear Geoserver-users,

I am fairly new to geoservers WFS and I have deployed the 1.5.0-war
successfully in my tomcat. Everything works nicely but when trying to
access geoserver-wfs with a simple GetFeature-POST-Request on the
sampple-data, geoserver dies with a NPE:

Request:
<?xml version="1.0" encoding="ISO-8859-1"?>
<wfs:GetFeature xmlns:ogc="http://www.opengis.net/ogc&quot;
xmlns:gml="http://www.opengis.net/gml&quot;
xmlns:wfs="http://www.opengis.net/wfs&quot;
outputFormat="GML2"
version="1.0.0"> <wfs:Query xmlns:topp="http://www.openplans.org/topp&quot;
typeName="topp:states">
<wfs:PropertyName>
topp:the_geom</wfs:PropertyName>
<wfs:PropertyName>
topp:STATE_NAME</wfs:PropertyName>
</wfs:Query>
</wfs:GetFeature>

Adding service="WFS" to the GetFeature-request returns the results
though.

Exception:
<html><head><title>GeoServer - Exception</title> <meta
content="text/css" http-equiv="content-style-type"> <style
type="text/css"> <!-- @import url("/geoserver/style.css"); -->
</style> <link type="image/gif" href="gs.gif" rel="icon"><!-- mozilla
--> <link href="gs.ico" rel="SHORTCUT ICON"><!-- ie
--></head><body><h1>GeoServer - Exception</h1>The following exception
was thrown:<br><i><code>java.lang.NullPointerException</code></i>
</body></html>

AFAIK it should return something, that service="WFS" is missing in the
request, but no NPE.

Is this a known problem?

Yep, we should state the request is invalid according to the WFS GetFeature xml schema, that mandates the attribute specification:

...
<xsd:attribute name="service" type="xsd:string" use="required" fixed="WFS"/>
...

I've opened an issue to track this, we'll fix it by 1.5.1:
http://jira.codehaus.org/browse/GEOS-1069

Thanks for reporting :slight_smile:
Cheers

Andrea,

This is a dupe of http://jira.codehaus.org/browse/GEOS-1059

I've got the fix running on my computer, and i'll commit before the end of the day.

Ah-ha, thank you :).
Well, in fact looking at the issue commit logs, it seems you already committed a fix, cool... is it only a partial fix?
Ah, btw, I don't see the forward port to trunk.

Cheers

I'm pretty sure it's not relevant to trunk (the dispatching system is TOTALLY different) but I'll know for sure soon.

Also if I've committed the fix, I'll bet it's the whole fix.

Let me double-check that and then close both JIRAs if needed.

Ouch, right.... I probably need a holiday :-p
Anyways, double checked, and in fact could not reproduce on trunk.
