Hi,

Did you (or anyone else) ever figure out this problem? I have almost the same error message trying to do use WS-Security for encrypting and signing messages:

P.S. I'm using neither axis nor jdk 1.6, but rather jboss-4.2.3.GA, JAX-WS SLSB EJB Webservices, and JDK 1.5.0_16

There was a discussion on WS-Secuiryt a while back, see if this helps: http://www.jboss.com/index.html?module=bb&op=viewtopic&t=127824
