> When I have multiple WARs deployed in the same Tomcat instance, I receive the following exception when attempting to verify a signature in the security header:
> Caused by: javax.xml.crypto.dsig.XMLSignatureException: javax.xml.crypto.dsig.TransformException: java.lang.ClassCastException: org.apache.ws.security.WSDocInfo cannot be cast to org.apache.ws.security.WSDocInfo

> When I put each WAR into its own Tomcat instance, the issue does not occur. I am using WSS4J with CXF on Tomcat 7.0.16.
> I do not know much about the implementation of WSS4J, but I suspect this is a class loader issue related to https://issues.apache.org/jira/browse/WSS-282.
