Custom Authenticator class not found

[barramundi]

JBOSS 4.0.5GA

Wrote a similar Authenticator to GenericHeaderAuthenticator
(http://wiki.jboss.org/wiki/Wiki.jsp?page=GenericHeaderBasedAuthentication)
and placed the jar file at
<jboss-4.0.5.GA>\server\default\deploy\jbossweb-tomcat55.sar

However JBoss can't find it throwing error
java.lang.ClassNotFoundException: TestAuthenticator

Tried to place at
<jboss-4.0.5.GA>\server\default\lib &
<jboss-4.0.5.GA>\lib
but JBoss does not find it as well.

Even tried to place the class file inside <jboss-4.0.5.GA>\server\default\deploy\jbossweb-tomcat55.sar\tomcat55-service.jar

Where should I place the custom authenticator in order for JBoss to find it?

In the jboss server classpath :- either under $JBOSS_HOME/server/default/lib or modify the %CLASSPATH% in run.bat/run.sh and add the jar location there

Actually I tried that after posting this topic, but got the same error.
I edited the run.bat to include the jar file
-classpath "%JBOSS_CLASSPATH%;C:\jbosscustauth.jar"

error as below:

Found the problem to be compiler JDK version.
Referring to http://wiki.jboss.org/wiki/Wiki.jsp?page=DeterminingClassVersionFromADotClassFile
I found the bytecode major version to be jdk 1.5

Compiled back with 1.4 and the problem is gone.

Strange though, that the error was not java.lang.UnsupportedClassVersionError
