RE: [Springframework-developer] Example classes needed

[Lars F. <lar...@gm...>]

Thomas,

thanks a lot, deployment works now.

There is one error message when undeploying but I hope alle these
missing classes are included in the next release.

Regards
Lars

P.S.: Error when undeploying (do not forget in 1.0):

Failed while destroying servlet: contextLoader.
java.lang.NoSuchMethodError:
com.interface21.web.context.ContextLoader.closeContext(Ljavax/servlet/ServletContext;)V
