Hi,
i'm new to geotools and started working through the userguide. everything
went fine until i got to the
postgislab. i've tried the code from userguide as well as the code from the
demo directory of the source distribution, but always get the following
error:
06.05.2009 14:52:29 org.geotools.data.DataAccessFinder getDataStore
WARNUNG: Problem asking Postgis if it can process
request:java.lang.AbstractMethodError:

Exception in thread "main" java.lang.NullPointerException
at org.geotools.demo.PostGISLab.main(PostGISLab.java:53)
and i have no idea how to debug the code nor how to fix the error. i'm
working with eclipse3.3 on
winxp-machine.
any hints, advices please?
thanks
hans
