Collections and JAX-RS

As I had previously reported, both RestEasy and Jersey both suffered from the inability to return a collection of JAXB marshalled objects. I was thinking on this a little, and while I could use the JAXBCollection fix in Jersey, it seemed a little bit of a hack until it goes into the 1.0 release. Instead (for now), I have written a few wrapper classes which they themselves are XmlRootElements thus supporting marshalling with JAXB. This actually worked and is a reasonable workaround (since I really only need to return collections for four to five persistent objects. These wrapper objects simply have a collection/list of the persistent objects with the XmlElement set to have the appropriate name of the child elements for processing:

   package org.javad.stamp.model.collections;

   import java.util.ArrayList;
   import java.util.List;

   import javax.xml.bind.annotation.XmlElement;
   import javax.xml.bind.annotation.XmlRootElement;
   import javax.xml.bind.annotation.XmlTransient;

   import org.javad.stamp.model.Country;

   @XmlRootElement(name="countryList")
   public class CountryList {

     @XmlTransient
     public List countries = new ArrayList();
 
     public CountryList( ) { }
 
     public void setCountries( List c ) { countries = c; }

     @XmlElement(name="country")
     public List getCountries() { return countries; }
 
     public void addCountry( Country c ) { countries.add(c); }
   }
