WFS Plugin for OpenJUMP
The current stable version of the WFS-Plugin can be downloaded from OpenJUMP's SourceForge pages. From there one can also access the subversion repository to get the latest version.
To install the WFSPlugin you need a wfsplugin.jar. This can be downloaded or built with ant. To install the .jar just copy it into the lib/ext directory of your OpenJUMP installation and restart OpenJUMP.
See the release notes for features of the various versions.
