XML Schema mapping error when generating web service

Question

I have created a method in java that returns an array of an object type (a user defined class). When tried to generate a web service JDeveloper did not allow me to select the method, giving the following "Why not.." explanation: "One or more parameters did not have an XML Schema mapping and/or serializer specified".
Can anyone help me in this?
Thanks
Alina

Thanks Mike for your advice it did work when I changed the setters and getters names, and managed to create a web service with Apache Soap profile. I created the client stub and client application to run the web service but it keep coming with soap-env error messages.
Error message I get when running the client side:
F:\JDev9i-0-3\jdk\bin\javaw.exe -ojvm -classpath F:\JDev9i-0-3\jdev\mywork\OrbatListArray\OrbatClient\classes;F:\JDev9i-0-3\jdev\lib\jdev-rt.jar;F:\JDev9i-0-3\jdev\lib\jdev-rt.jar;F:\JDev9i-0-3\soap\lib\soap.jar;F:\JDev9i-0-3\lib\xmlparserv2.jar;F:\JDev9i-0-3\jlib\javax-ssl-1_2.jar;F:\JDev9i-0-3\jlib\jssl-1_2.jar;F:\JDev9i-0-3\j2ee\home\lib\activation.jar;F:\JDev9i-0-3\j2ee\home\lib\mail.jar;F:\JDev9i-0-3\j2ee\home\lib\http_client.jar orbatclientpackage.OrbatListArrayClient

When I deployed it to jar I copied the jar file in the following directory:
<jdevloper home>\soap\webapps\soap\soap\Web-inf\lib\
I then tried and created a client stub in the same package using JDeveloper 9.0.3 wizard for creating sample java client and added a line to call my getOrbatListArray method and print it to the screen. I get another soap error message, saying:

Sorry for the length of this message, but I am getting desparate.
Thanks again for all you help
