What is jaxbelement in java

Since in JAXB classes correspond to complex types a way is needed to capture which root element was encountered. For more details see this article I wrote. There is a choice structure where either foo or bar elements can occur and they are the same type. Here a JAXBElement is required because simply encountering a String value isn't enough to indicate which element should be marshalled. An element with xsi:nil is encountered in the document that contains attributes.

In this example the object corresponding to that element can still be unmarshalled to hold the attribute values, but JAXBElement can stil indicate that the element was null. In the above code, even if i try to marshall expense object, it generates the same XML output.

AmanArora - What does the Expense class look like? Did you modify it after it was generated from the XML schema? ExpenseT" as an element because it is missing an XmlRootElement annotation. Sorry the last comment was wrong.. AmanArora - I wrote a blog post about root elements that you may find useful: blog. Thank you. I will go through it now. Mathias G.
