javax.servlet.ServletException: Wrapper cannot find servlet class

[HARI OM]

I am using JBoss 4.0.1sp1 on SuSE Linux 9.0 System.
I have a WEB APPLICATION and access it using
http://localhost:8080/mhin/admin.html and here is my Directory
structure...

/jboss/server/default/deploy/mhin.war --> this is a directory.
/jboss/server/default/deploy/mhin.war/admin.html
/jboss/server/default/deploy/mhin.war/WEB-INF/web.xml
/jboss/server/default/deploy/mhin.war/WEB-INF/classes/t1.class
/jboss/server/default/deploy/mhin.war/WEB-INF/classes/t2.class
/jboss/server/default/deploy/mhin.war/WEB-INF/classes/util/p6.class
/jboss/server/default/deploy/mhin.war/WEB-INF/classes/util/p9.class

When I click on http://localhost:8080/mhin/admin.html I get following
ERROR wonder why...
(this HTML calls t1.java file)

-------------------------------------------------------------------
NOTE: t1.java and t2.java have "import util.*" in their declarations.
and p6.java and p9.java have "package util" in their declarations...

Questions:
Are all the classes in the right directory?
Am I using the right FQDN? Fully Qualified Domain Name? in my WEB.XML?
Any other hints/ relevant informaiton would be appreciated...

Sincerely,
