How to add inline xml schema using jaxb?

Is it a good idea to use JAXB to generate XML? Why or why not?

• I often see situations where JAXB is not flexible enough. For example,  we may want to generate XML dynamically. Some fields contain the data that need to be passed around. But when we return the data to users, we may want to hide the fields determined by request parameters. Since I always see exceptions when using JAXB. I start to wonder if it is a good idea to use JAXB.

• Answer:

  It is pretty straightforward to modify the output created by the JAXB Marshaller by using one of the versions of the marshal method that outputs to a SAX2 ContentHandler or a JAXP Result instance (which could be backed by DOM, SAX, StAX, or stream-based implementation). If you use one of the stream-based output methods, then you're stuck with whatever JAXB gives you, but not if you use one of the other methods. Whether or not it's a good idea for you to use JAXB in light of the former depends on whether you have any other objections to it. Your basic choice is between an annotation-based framework like JAXB or one based on external code or configuration (e.g. XStream). If you want to use annotations on your objects to drive XML output, then JAXB 2.1 has the benefit that it is bundled with Sun/Oracle's Java 6 JDK. This has the negative aspect of making it a nightmare to use a newer version of JAXB (it involves using the endorsed library path mechanism).
