[Users] Building a WFS-T-application; Problem rendering WFS

[andreia farrér]

I've now added the following line to my code:

 <script type="text/javascript" src="/proj4js/lib/proj4js.js"></script>
>

Is that sufficient or do I have to add someting like a
reprojection-statement in my WFS-definition?
Cheers
Andreia
