[jboss-user] [JBoss Seam] - Why I got java.lang.NoClassDefFoundError when using somethin

I use seam2.0GA along with richfaces3.1.2GA. If I didn't use UITree in my code, everything is alright. However, if I used something like UITree or TreeState, I got java.lang.NoClassDefFoundError org/richfaces/******/UITree or TreeState In the source code, I can import these lib correctly. The point is :If I didn't use UITree in my code, everything is alright. However, if I used something like UITree or TreeState, I got the error. Has anyone met such problem before?How to solve it?
