Serialization error while invoking a Java web service

Question

Hi,
I've a requirement where I need to create a Java web service, which returns a collection (a set of records).
The way I've created a web service is by having a Java Class, which internally calls a Pl/sql package returning Ref cursors and a bean Class, which wraps the method of the Java Class, to return the collection. I could create the web service successfully and could invoke the end point. The end point looks like this: http://localhost:8988/MyJavaWebService-New_JWS-context-root/MyWebService_finalSoapHttpPort
The method exposed for the web service in my Java class is of type ArrayList, to fetch the collection element.
After giving the input at the end point, while I say invoke, for the web service, I get the following error:
<env:Envelope
xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:ns0="http://mypkg/types/"
xmlns:ns1="http://www.oracle.com/webservices/internal/literal">
<env:Body>
<env:Fault>
<faultcode>env:Server</faultcode>
<faultstring>Internal Server Error (serialization error: no serializer is registered for (class mypkg.EmpBean, null))</faultstring>
</env:Fault>
</env:Body>
</env:Envelope>
I've tried making my exposed method of type Vector as well and re-generated the web service. But still I face the same issue at invocation.
Can anybody help me out and hint me on how I should proceed? I'm not sure if my approach is correct and so please correct me if I'm wrong.
Thanks in Advance,
Gayathri
