This is a known issue with eclipse 3.3.1 and Leopard.
1) Don't use Leopard ;)
2) Use Eclipse 3.3.2 (but don't upgrade to WTP 2.0.2 since they introduced a regression bug in there that prevents proper deployment of Seam)
I'm already on Eclipse 3.3.2 when I get this behavior. Build id is M20080221-1800.
WTP shouldn't be an issue as I deploy using ant build files...
Any other versions or settings I should check?
then i don't know a solution...it should just work.
I re-downloaded the JBoss Tools plugins and... as described, it just worked.
There must have been something wonky about my install... thanks for helping me figure out that it must have been something local.
