Hello
Wms spec says that i can use only a point in request - GetFeatureInfo. When i define icons for my points layer i have problem. User could not clicked in point where he get request, he almost all the time get empty answer.
Could i deffine a buffer for this type of request?! When user will clic on my icon he get the request for this point!?

By WMS spec, you cannot define a buffer size, and GeoServer does not
have any vendor parameter to allow you to specify one.
There are already quite some GetFeatureInfo improvement requests
related to your problem, for example:
http://jira.codehaus.org/browse/GEOS-1434
http://jira.codehaus.org/browse/GEOS-880
http://jira.codehaus.org/browse/GEOS-1008
Unfortunately so far none of the companies/developers supporting
GeoServer has had the time or interest to work on them (I'm assigned
to all of them just because I'm the default target for all new
issues). If you really need that feature now you still have two
options, that is, trying to code it up yourself (patches are more
than welcomed) or ask someone to do it for you, there are
commercial support options available at:
http://geoserver.org/display/GEOS/Commercial+Support

Ok, thx very much for the answer. I think that i only could not find that option.

I am running geoserver 1.6.3 and 52 North's WPS 1.0 under Tomcat. Most of the time everything works fine. However, occasionally, when the WPS makes a WFS call to geoserver it has trouble reading the results. The error from the WPS is

Somehow, the data being returned from te WFS to the WPS is getting corrupted. My guess is that it is an issue with java.text.format.NumberFormat. We have seen problems with this class since it is not thread safe and must be synchronized. This is only a guess, any thoughts? I'm not sure exactly where the problems occurs: in geoserver generating and sending the data or in wps receiving and parsing the data, that is why I have cross posted both mailing lists. Any help, ideas, or guidance would be appreciated.

I quickly looked in the GML2 generator, the NumberFormat is instantiated
in CoordinateWriter class when the object is created, and I don't see
any caching of the CoordinateWriter, so this one should be thread safe
(each thread ends up creating its own CoordinateWriter).
Same goes for the parser, it's actually using Double.parseDouble(t)
which should be thread safe.
I'm more curious of this "V.00650868" value. Is it a possibly legitimage
value in your GML? Maybe there is an unclosed tag somewhere, don't know.
Can you double check?
Cheers
Andrea
