Chris, Thanks for the reply. I discovered what the problem was. You were right. The vector was being returned empty. I was populating it from a database. My SQL statement was incorrect. I fixed it and recompiled the service. However, I kept getting an empty vector. When I restarted Apache and Tomcat, my recompiled service was loaded and it worked. Does SOAP cache classes? Is there a way to refresh? Thanks again.

I'd guess that getAllEmployees just doesn't have any data to return. Try modifying the server endpoint for that routine and hardcode in some Employee objects into the returned Vector. If you still don't get any data, then there's likely a mapping problem...but from the looks of it, however you're populating the return Vector probably just doesn't have any data to fill it with. Can you show us how you're populating the Vector? -Chris -----Original Message----- From: Chris Orloff [mailto:[EMAIL PROTECTED]] Sent: Tuesday, November 27, 2001 1:28 AM To: [EMAIL PROTECTED] Subject: Empty Vector Returned 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" Set-Cookie: JSESSIONID=lshg4z3g81;Path=/soap Servlet-Engine: Tomcat Web Server/3.2.3 (JSP 1.1; Servlet 2.2; Java 1.2.2; Windows 95 4.10 x86; java.vendor=Sun Microsystems Inc.) <?xml version='1.0' encoding='UTF-8'?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/1999/XMLSchema";> <SOAP-ENV:Body> <ns1:getAllDepartmentsResponse xmlns:ns1="urn:Personnel" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";> <return xmlns:ns2="http://xml.apache.org/xml-soap"; xsi:type="ns2:Vector"> <item xsi:type="ns1:com.transync.data.Department"> <ID xsi:type="xsd:int">1</ID> <name xsi:type="xsd:string">Marketing</name> </item> <item xsi:type="ns1:com.transync.data.Department"> <ID xsi:type="xsd:int">2</ID> <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 Set-Cookie2: JSESSIONID=6awmcg3jz1;Version=1;Discard;Path="/soap" Set-Cookie: JSESSIONID=6awmcg3jz1;Path=/soap Servlet-Engine: Tomcat Web Server/3.2.3 (JSP 1.1; Servlet 2.2; Java 1.2.2; Windows 95 4.10 x86; java.vendor=Sun Microsystems Inc.) <?xml version='1.0' encoding='UTF-8'?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"; xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/1999/XMLSchema";> <SOAP-ENV:Body> <ns1:getAllEmployeesResponse xmlns:ns1="urn:Personnel" SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";> <return xmlns:ns2="http://xml.apache.org/xml-soap"; xsi:type="ns2:Vector"> </return> </ns1:getAllEmployeesResponse> </SOAP-ENV:Body> </SOAP-ENV:Envelope> 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
