The WFS datastore has some class dependencies on the WMS plugin.
Please ensure they are both on your ClassPath.

Re: [Geotools-gt2-users] WFSDataStore help

[Nicolas R. <nic...@gm...>]

Hello Lena,

This time, the missing jar seems to be vecmath-1.3.jar.

To be sure not to miss any library, you should include gt2-main.jar
(I'm sure it's already done :-) and all jars contained in the "shared"
folder, that are needed for gt2-main.

Then, for each plugin you use, include the plugin's jar and all its
dependencies, that you will find in the "lib" subfolder of the plugin
folder.
For instance, if you use the postgis datastore, you should include
gt2-postgis.jar and
lib\postgis-driver-1.0.jar
lib\postgresql-3.0.jar
lib\wkb4j-1.0-RC1-modified.jar.

Also be sure to include extension's jar if you use any of them
(projection, graph....)

(I'm talking about geotools 2.0.0, for other releases, paths may be
slightly different)

Another solution is to include ALL jars you will find in the geotools folde=
rs !
