Creating a Web Service from EJB 3.0 - J2SE 5.0 Collection mapping problem

Question

Hi,
Apologies if this is the wrong forum, I'm not quite sure where it fits in.
I have some Toplink JPA entity beans that I access through a session bean. I am then trying to create a web service based on the session bean by deploying it to a 10.1.3 application server. This is based on the documentation at http://download.oracle.com/docs/cd/B31017_01/core.1013/b28764/web_services002.htm#CHDJEDDH
The two entity beans are like:
public class Event {
private java.util.List<EventDetail> eventDetailList;
public Event() {
public void setEventDetails(java.util.List<EventDetail> eventDetailList) {
this.eventDetailList = eventDetailList;
public java.util.List<EventDetail> getEventDetails() {
return eventDetailList;
public void addEventDetail(EventDetail eventDetail) {
this.eventDetailList.add(eventDetail);
public class EventDetail {
public EventDetail() {
The session bean has a method like:
List<Event> listParents();
When this is deployed to the application server I expected a complex type like ListOfEventDetail to be generated in the WSDL, as shown in http://download.oracle.com/docs/cd/B32110_01/web.1013/b28975/apptypemapping.htm#sthref966, and the Event complex type would have an element of ListOfEventDetail. Instead the Event complex type looks like this:
<complexType name="Event">
<sequence>
<element name="eventDetails" type="ns1:list" nillable="true"/>
</sequence>
</complexType>
<complexType name="EventDetail">
<sequence/>
</complexType>
and ns1:list appears in a different schema:
<schema xmlns="http://www.w3.org/2001/XMLSchema" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap11-enc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="http://www.oracle.com/webservices/internal/literal" targetNamespace="http://www.oracle.com/webservices/internal/literal" elementFormDefault="qualified">
<import namespace="http://wsdl/"/>
<complexType name="list">
<complexContent>
<extension base="tns:collection">
<sequence/>
</extension>
</complexContent>
</complexType>
<complexType name="collection">
<sequence>
<element name="item" type="anyType" minOccurs="0" maxOccurs="unbounded"/>
</sequence>
</complexType>
</schema>
However, if I change the getters and setters for eventDetailList in Event to setDetails and getDetails like this:
public void setDetails(java.util.List<EventDetail> eventDetailList) {
this.eventDetailList = eventDetailList;
public java.util.List<EventDetail> getDetails() {
return eventDetailList;
the WSDL is generated as I expected:
<complexType name="EventDetail">
<sequence/>
</complexType>
<complexType name="Event">
<sequence>
<element name="details" type="tns:ListOfEventDetail" nillable="true"/>
</sequence>
</complexType>
<complexType name="ListOfEventDetail">
<sequence>
<element name="item" type="tns:EventDetail" minOccurs="0" maxOccurs="unbounded"/>
</sequence>
</complexType>
After messing around with various combinations of things, it seems that if the getters and setters have more than just the initial capital letter the (eg getTheThings instead of getThings) the WSDL gets messed up. Does anyone have any ideas what is going on here?

Answer 1

Using <autotype> and <source2wsdd> to generate what I need. Now WL seems happy.
