Hello, Sorry for the delay of my reply. Actually, the "dynamically" java classes is an ideal feature for me, but not a must. I build up an implementation of JAXB Unmarschaller, that uses xjb compiler and generates java classes. Is a static implementation of course, but it works fine, if the xml file will not be changed. I'm still researching for a solution that will have as input an xml file, and based on xml schema will be able to read information from the input xml file. I can use xpath for that, but I need the java classes generated by the xjc compiler for each xml elements. The link between xml elements and java classes is very important for my application. Thank you very much for the answer. Best regards, marius costa View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4110205#...
