Errrrr.....


what confuses me:

It seems like the Exception is thrown in the decode64()-method of org.apache.myfaces.renderkit.html.HtmlResponseStateManager. I had a look in the MyFaces-Impl-Jar that came with Seam.... and guess what? This method doesn't exist there. And I found out that Seam has MyFaces 1.1.3, but it seems that JBoss-4.0.4.GA uses MyFaces 1.1.1 which is in $JBOSS_HOME/server/default/deploy/jbossweb-tomcat55.sar/jsf-libs. And the 1.1.1 version has that decode64() method, so the old version is being used.

...HOWEVER...

I overwrote the old MyFaces Jars with the new ones, but the error persists... with a slightly different Exception (but still ClassNotFound):
