No Classloaders Found Error while deploying seam-gen'ed sample project

recool.qiao_haibo.hotmail.com Nov 1, 2008 8:45 AM

Hi All,

Using Seam 2.1.0.SP1, I generated a simple seam project from db(only 2 tables) using seam-gen(seam generate-entities). it went all fine until I try to startup jboss server(4.2.3), the error is attached below.
Then I tried jboss 5.0.0, the error is similar.
