Empty Vector Returned

Mon, 26 Nov 2001 23:23:00 -0800

Hi,
 
I have two services, both return vectors of objects. The first, called getAllDepartments(), returns Department objects. The second getAllEmployees() returns Employee objects. Both Department and Employee are very simple classes, containing private data and get and set methods.
 
When I call getAllDepartment(), the return message is:
 
HTTP/1.0 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: 798
Set-Cookie2: JSESSIONID=lshg4z3g81;Version=1;Discard;Path="/soap"

<item xsi:type="ns1:com.transync.data.Department">

<name xsi:type="xsd:string">Finance</name>
</item>
</return>
</ns1:getAllDepartmentsResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
 
This is perfect, great, just what I want. However, when I call getAllEmployees(), I get this message:
 
HTTP/1.0 200 OK
Content-Type: text/xml; charset=utf-8
Content-Length: 520

It's empty. I wrote a test driver for my service to make sure it is returning something, and it is. Here's the mapping code in the client:
 
    SOAPMappingRegistry smr = new SOAPMappingRegistry();
    BeanSerializer beanSer = new BeanSerializer();

    smr.mapTypes(Constants.NS_URI_SOAP_ENC,
                 new QName("urn:Personnel", "com.transync.data.Employee"),
                 com.transync.data.Employee.class, beanSer, beanSer);
 
    smr.mapTypes(Constants.NS_URI_SOAP_ENC,
                 new QName("urn:Personnel", "com.transync.data.Department"),
                 com.transync.data.Department.class, beanSer, beanSer);
 
And here's the mapping in DeploymentDescriptor.xml:
 
<isd:mappings>
        <isd:map encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
                 xmlns:x="urn:Personnel" qname="x:com.transync.data.Employee"
                 javaType="com.transync.data.Employee"
                 java2XMLClassName="org.apache.soap.encoding.soapenc.BeanSerializer"
                 xml2JavaClassName="org.apache.soap.encoding.soapenc.BeanSerializer"/>
        <isd:map encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
                 xmlns:x="urn:Personnel" qname="x:com.transync.data.Department"
                javaType="com.transync.data.Department"
                 java2XMLClassName="org.apache.soap.encoding.soapenc.BeanSerializer"
                 xml2JavaClassName="org.apache.soap.encoding.soapenc.BeanSerializer"/>        
       </isd:mappings>
 
Any ideas on why these two very similar objects are behaving differently would be very welcome.
 
Thanks,
Chris
