JBoss3.0.1+Tomcat4.0.4 Struts Example fail

[lj123@xxxxxxx (Lih-Ji Wang)]

Hi,
   Has anyone tried JBoss3.0.1+Tomcat4.0.4 integrated version with Eclipse
JBoss plugin (Genuitec Eclipse JBoss Plugin 1.05)? I'm having problem
running struts examples inside Eclipse. Previous JBoss3.0+Tomcat4.0.3
works fine and, if JBoss (the new version) started outside the Eclipse all
examples run fine also. Here is the error message I got and thanks for the
help.
