[Geoserver-users] Can't access my maps...

Jason_Hamilton · April 29, 2009, 3:54pm

Hello all. First off, I'd like to point out that I am a new user to
GeoServer and there's a good chance that my problem is one of stupidity and
not of technical failure. That having been said, when I attempt to create a
new dataset from a shapefile and add the FeatureSet, I end up with a link on
the Preview/Demo page to my dataset (PBSS:TerminalA). When I click on the
'OpenLayers' link to view the map, my browser attempts to download a file
called 'wms' (no extension). However, if I try to use
http://localhost:8080/geoserver/wfs?request=getfeature&service=wfs&version=1.0.0&typename=PBSS:TerminalA
I get an XML file that, to my untrained eye, looks correct. Can anyone out
there please help? Thanks in advance.

The WMS is sending out a SerivceException report, which is actually just
an XML file (but with a strange content type attached to it, mandated by
the WMS spec, that prevents browsers from just showing it directly).

The most common case for that happening is that you configured a style
for your layer that requires attributes that are not actually there.
Reading the service exception will provide more insight.

Cheers

Thanks, Andrea, at least that gave me somewhere to look. I opened the XML
exception file and it reads:

<?xml version="1.0" encoding="UTF-8" standalone="no"?><!DOCTYPE
ServiceExceptionReport SYSTEM
"http://schemas.opengis.net/wms/1.1.1/WMS_exception_1_1_1.dtd">
<ServiceExceptionReport version="1.1.1" > <ServiceException>
java.lang.reflect.UndeclaredThrowableException
null
null
null
</ServiceException></ServiceExceptionReport>

Which doesn't help me much. Are you implying that the person who provided
the shape file possibly didn't give me a complete one?

Thanks again,
Jason

Hmm... oh, that exception usually occurs when GeoServer
libraries are mismatched, which can occurr if you overwrite
a previous GeoServer installation with a newer one.

Do one thing, go into config -> server and enable "verbose
exceptions", apply, save, and then try to access the
map again. The service exception should be a lot more detailed,
report it back on the list, that should help me figure out what is
happening

I would also add, and I am assuming that this is normal in the case of an
error like this, that every time I restart GeoServer, the dataset persists,
but I have to re-attach the FeatureSet and replace the SRS field. I only
mention it in case it helps solve the issue.

Many many thanks,
Jason Hamilton
