[Geoserver-users] NullPointerException on GetFeatureInfo request

Thomas_Rokkjaer · June 14, 2007, 9:13am

Hi there

I get the following exception returned from my wms:GetFeatureInfo request sent from MapBuilder to GeoServer:

Where my request looks like this:
http://infudv1:8080/geoserver/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&LAYERS=brnby:DasKnude&SRS=EPSG:25832&BBOX=714784,6169191,715625,6169751&WIDTH=600&HEIGHT=400&INFO_FORMAT=application/vnd.ogc.gml&FEATURE_COUNT=1&QUERY_LAYERS=brnby:DasKnude&X=402&Y=239&FORMAT=image/png

Is there somewhere within the Geoserver admin, where you have to setup that it should be possible to make a getfeatureinfo request on a specific datasource?
The layer brnby:DasKnude is a simple shapefile located on the server.

Environments:
MapBuilder 1.0rc2
GeoServer 1.4.1 on Tomcat 5.5
IIS
Windows 2003 Server

Best regards

This is a known bug, http://jira.codehaus.org/secure/ViewIssue.jspa?key=GEOS-933.
Unfortunately it has been fixed after 1.4.1 was released. There won't
be a 1.4.2 release, so I suggest you try and update to 1.5.1 (you would
get extra functionality and speed improvements, but beware, in
1.5.1 we don't include MapBuilder anymore, so you have to
provide it by yourself, possibly using this war: http://docs.codehaus.org/display/MAP/Installing+MapBuilder).

Thanks Andrea.

We upgraded GeoServer to 1.5.1 and now the response is the following (looks like it presumes I am requesting a WFS featurecollection):

<?xml version="1.0" encoding="UTF-8"?>

<wfs:FeatureCollection xmlns:wfs=“http://www.opengis.net/wfs”
xmlns:brnby=" http://www.bronby.dk/"

gml:boundedBy
gml:nullunknown</gml:null>
</gml:boundedBy>
</wfs:FeatureCollection>

I found that I had to add a FORMAT parameter in my URL, which looks like the following: http://infudv1:8080/geoserver/wms?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetFeatureInfo&LAYERS=brnby:DasKnude&SRS=EPSG:25832&BBOX=714784,6169191,715625,6169751&WIDTH=600&HEIGHT=400&INFO_FORMAT=application/vnd.ogc.gml&FEATURE_COUNT=1&QUERY_LAYERS=brnby:DasKnude&X=402&Y=239&FORMAT=image/png
The INFOFORMAT parameter is set to “application/vnd.ogc.gml”.

Got any idea, what could be causing this response now?

Best regards

Sorry, it's 23.00 here so I may be loosing some important detail but... what' wrong with the first output? Seems like a good response when you
click on a zone that has no features. It's valid GML2 as far as I can
see, and the output format you're requesting is in fact GML...

Cheers
Andrea

Justin_Deoliveira · June 21, 2007, 9:13pm

Hi Thomas,

So i think you are getting the correct output no? What are you expecting
to see back?

When you set INFO_FORMAT to "application/vnd.ogc.gml" you are supposted
to get back a feature collection. The only problem seems to be that
there is no feautres includes in the feature collection which means
there were no hits at X=402, Y=239.

This is a MapBuilder solution where I get a “error loading page” message each time I use the Info button. The particular layer (points) has been set to queryable in the config.xml file.
Besides this, I am pretty sure I am pointing at a location where there is a feature and would expect information from this feature.
I am becoming a bit desperate. Would really like to see information from this layer…

Hi Thomas,

Yeah the url looks fine and you are getting a response back, just an
empty one. It could be that an empty response is throwing off
mapbuilder? This may be an issue for the mapbuilder list.

Another thing you may want to try is to start with an example that
works. In the geoserver sample requests page you should see a
featureInfo example for the states layer. Try playing with it and see if
it works for you.

    This is a MapBuilder solution where I get a "error loading page"

    (points) has been set to queryable in the config.xml file.
    Besides this, I am pretty sure I am pointing at a location where
    there is a feature and would expect information from this feature.
    I am becoming a bit desperate. Would really like to see information
    from this layer...

        Hi Thomas,

        So i think you are getting the correct output no? What are you
        expecting
        to see back?

        When you set INFO_FORMAT to "application/vnd.ogc.gml" you are
        supposted
        to get back a feature collection. The only problem seems to be that
        there is no feautres includes in the feature collection which means
        there were no hits at X=402, Y=239.
