Isn't there a forum example in the Seam download?
Thanks for your information, but I still don't know where exactly in the Seam download??
I had looked for example of forum Seam.
On the bottom left hand side of this forum where the Seam menu is look at what it says.
Built with Seam You can find the full source code for this website in the Seam package in the directory /examples/wiki. It is licensed under the LGPL.
So, download Seam and unzip/extract it.
Browse to the folder where you extracted it to.
From there go to. -> examples -> wiki
I'm not sure if this contains all the forum code but... I'm just going off what is written on the left hand side of this site.
If you haven't written a Seam app before then I would suggest doing a number of tutorials of smaller things first. A forum is not a simple task to write.
Ultimately though, spend some time in the examples directory of the Seam project it will help you lots.
