Question

I am using JAXB to serialize data to XML from java objects. I do not want to create some nodes if the xml is requested by unauthorized user.

Can this be done using JAXB?

Few non-JAXB solutions I can think of are:

1. Remove nodes after generating XML with Regex or XSLT.
2. Set the values of objects corresponding to the hidden nodes to null.

What will be the suggested approach?

Answer 1

Note: I’m the EclipseLink JAXB (MOXy) lead, and a member of the JAXB 2 (JSR-222) expert group.

Using any JAXB Implementation

You could use XSLT and leverage the JAXBSource object as the input to the transformation.

JAXBSource source = new JAXBSource(jaxbContext, myPOJO);
Result result = new StreamResult(System.out);
transformer.transform(source, result);

Using MOXy JAXB

If you are using the MOXy implementation of JAXB you could use its XML metadata to apply a second mapping to your object model.
