Hi!
I was trying out WFS demo available on GeoTools User Guide Wiki web site
http://docs.codehaus.org/display/GEOTDOC/WFS+Plugin.
The problem is that it works only with some of the data. Mostly with those
that come along with Geoserver instalation. The problem appears when I use
the demo on the data that are stored in POSTGIS data bank.
I realy do not know where is the problem. NetBeaans indicate that there is
NullPoIntException in this code line:
FeatureReader ft = wfs.getFeatureReader(query, Transaction.AUTO_COMMIT);
this the whole error message that I get when I run the WFSDemo:
