Hello,

I've never encountered such a situation myself, but it may be because of a
duplicate jar in your classpath. As you may know, looking in WEB-INF/lib

Maybe you should have a look at this, in order to know where to look :


http://tomcat.apache.org/tomcat-6.0-doc/class-loader-howto.html

HTH,

Pierre
