Hello -

using jboss-4.2.2GA with Seam 2.0.2.SP1 on winxp. upon deployment java.lang.NoClassDefFoundError appears as 'Caused by:' in the stack trace.
But only in one of the two versions of the.ear file I've been deploying.
Both contain the same application java code, while other contents are different.
I am in the process of trawling through differences to identify which may be
responsible but have yet to meet with success.

jboss-seam.jar files are identical and contain these classes:

org.jboss.seam.core.Expressions$1.class
org.jboss.seam.core.Expressions$2.class
org.jboss.seam.core.Expressions$MethodExpression.class
org.jboss.seam.core.Expressions$ValueExpression.class
org.jboss.seam.core.Expressions.class

None of these are Expressions$ValueBinding. This is what I find most perplexing.
Anyone have any suggestions as to what is causing this anomaly? Any help most
appreciated.
