Hi Liu, I've developed a generic layer using JXpath on top of a JAXB object tree for the purpose of generating XML. You can actully get JXPath to work with the JAXB list implementation by extending JXpath with a ListElementFactory. I've included the Java source. This is explained in the JXpath docs.

I use JAXB to ummarshall xml string to get a java object and use this java object as a bean in woody binding. It can get data from the jaxb object without problem. But it failed to save the data back to the jaxb object(the error says: org.apache.commons.jxpath.JXPathException: Exception trying to create xpath ). I think it is due to two reasons: 1. The implementation of a sequence of child elements is different in JAXB. For example, suppose in your xml string you have a <course> element, which has a sequence of <chapter> elements. In jaxb, the Course object would have a field called ChapterType, then the ChapterType would have a field which is a list of Chapter objects. But in woody bean, it would require a Couse object having a field chapters. The chapters field itself should be a list of Chapter objects. So due to this different implementation, jaxb object cannot work in woody binding. 2. The other problem is that in jaxb object, for a list, it doesn't have set and add methods. It would expect you to use get method to get the list and then use the method provided by the list to manipulate it. I think this is the other reason. There might be other reasons that jaxb objects cannot work in woody binding. Anyone pointing out? I have tried to extend jaxb object and some other ways to see if it can work. But it seems a lot of trouble. So I already gave up using JAXB objects in woody binding. Has anyone done the similar work before? Are u able to get it work? Thanks. __________________________________ Do you Yahoo!? Yahoo!
