Problem with object lists in BPEL and not in WS (ElementNSImpl)

Question

Hi all, I've the next:
class Category{
   private List<Group> groups;
   private String name;
   public List<Group> getGroups(){
      return grops;
   public String getName(){
      return name;
}I've created a webservice that returns a Category in NetBeans:
@WebMethod
    public Category getMyCategory  throws Exception{  
        try {
            return new MyThing().getCategory();     
        } catch (Exception ex) {
            ex.printStackTrace();
            throw new Exception(ex);
    }Ok, If I call this WS in my jsp page or an app, I can access to the attribute "groups" (of the type "Category") as a List of "Group".
I've created a BPEL that does the same: return a Category. The same category. getName() works fine
But the list "groups" is a list of com.sun.org.apache.xerces.internal.dom.ElementNSImpl !
Using NetBeans 5.5 to do all.

You are perpetrating mistake #1 here. Don't try to send C structs over the wire. The format is dependent on the hardware, the operating system, the compiler, the compiler version, compiler bugs, the #pragmas, and the compiler options in effect. Too many variables. What you should be doing is writing the primitive types to the network, in network byte order, and reading them inJava with the appropriate methods of DataInputStream.
