Compile with JDK1.4 or include the JAAS libraries from jboss/client dir.
It appears that the jsse.jar is already included in the build.xml? Is there something else I am missing?
I will try with 1.4 of the JDK, but I would like to understand why it is not working with 1.3.
I found the jboss-jaas.jar and added it to the build path in the build.xml and the compile works fine now.
