How to add xml schema attributes using JAXB?

[kokababu]

Hi,

I have to add xml schema attributes into the java object.
Such as, my java object is User. This User object will be
represented as XML using JAXB. I generated XML
from User object successfully using JAXB. But I want to add xml schema attributes. For example:

<User
xmlns="http://testws/rest/schema"
xmlns:xsi="http ://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocat ion="http://testws/rest/user UserSchema.xsd" >
</User>

How do I add xmlns, xmlns:xsi, xsi:schemaLocat ion attributes in the User (root) element, using JAXB?
I tried with @xmlSchema annotation but it threw the following error:
Package annotations must be in file package-info.java

I would be grateful, if someone help me to solve this issue.

Hmmm, I understood nobody knows answer of my question. However, I overcome the problem. I just take out the jaxb api and I have used StaX now. StaX is cool because it gives me to work low level task such I can now attache my multiple external schemes with the parser and writer. I have successfully achieved my goal using StaX.
