I am using struts2 with hibernate. Does anyone know if it is possible to return query result as XML instead of ArrayList of domain objects?

Hibernate by default maps and persists a database record thought POJO , but in fact it also supports persisting , mapping and representing a database record in XML by using an experimental features called Dynamic models.
For example , to output a record in XML:
/**Get the a new session that is in the DOM4J EntityMode**/
Session dom4jSession = session.getSession(EntityMode.DOM4J);
Element outputXML=(Element) dom4jSession.get(Employee.class, employeeId);
XMLWriter writer = new XMLWriter( System.out, OutputFormat.createPrettyPrint() );
writer.write( outputXML);
To configure the format of the outputted XML , you can only do it by mapping the entity in XML . AFAIK ,there are no annotation equivalent .

Hibernate is an Object-Relational Mapper, meaning it maps a Relational database to objects. You want to use Hibernate to return an object and then use an XML Serializer to convert to XML.
The Simple Serializer is probably the best one to get started with. The Website contains a lot of tutorials and examples.

However there are a ton of XML Serializers for Java:
