[jboss-user] [JBossWS] - Casting porblem

Hi, I'm quite new with web services, so perhaps it is a stupid question. I'm working with JBoss 4.2.2 and I've installed JBossws-native 3.0.5. I've created a simple web service with he method that receive and List of objects. Something like this: public long startTramitadorInstance(String processName, List < Product > productList) Product is a superclass and I've set in it the @XmlSeeAlso tag with the subclasses. I use the wscompile included in the jbossws-native package tool to generate classese from the WSDL. And if I call this method from a client and the List is formed for several subclasses of the superclass, I always get an Exception: Caused by: java.lang.ClassCastException: com..beans.product.Product cannot be cast to com..beans.product.Subproduct Is that normal? Cann't I use superclasses or abstract classes in the methods of the web service? Am I doing something wrong? Thanks in advance Pablo View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4217622#...
