Hi Cocooners!

It seems I got in problem when I installed the Cocoon 1.7.4 as a Tomcat context, when I tried it, i got:
 
Error found handling the request.
            
                    java.lang.NoSuchMethodError: org.w3c.dom.DocumentType: method getPublicId()Ljava/lang/String; not found

Mmm, it seems that I the org.w3c.dom.DocumentType class is an older version that the requested...

any suggestions?

thanks in advance
