We are using JBoss 4.0.0, OS is Windows 2000, JDK 1.3.1.
Anyone know what the problem is? Thanks.

jboss-4.0.0 requires jdk1.4+.

I'm using JSF1.0.1 and J2SDK 1.5, Jboss 4.0.1, The following exeption thrown:

13:53:03,472 INFO [Server] JBoss (MX MicroKernel) [4.0.2 (build: CVSTag=JBoss_4_0_2 date=200505022023)] Started in 26s:468ms

Jboss or JSF doesn't support java1.5, does it?

Thanks

jboss-4.0.2 runs fine under jdk1.5 so I guess its this jsf implementation.
