I have seen some discussions on this topic already. In my case the exception won't raise when program is running alone or outside a j2ee container where the xml parser is presumbly a Sun compatible parser. But when running inside orion container, the runtime parser is an oracle XMLParser that may not conform to latest specifications of xl parser. I'm reluctant to turn off unmarshaller's validation. Is there any workaround for this problem? BTW, will jaxb have its own platform independent sax parser?
My exception stack trace is attached as follows and suspecious statements are highlighted.
