I'm trying to whip-up a bare-bones service that will demonstrate
Axis2's inability to cope with complex data types returned by service
methods using RPCMessageReceiver and now I can't even get *that* to
work (what a way to start off the week). Here's the service
implementation:
public class TestService {
public String[] getArrayOfStrings() {
return new String[] {"Hello", "World"};
}
public int getInt() {
return 1;
}
public Object getObject() {
return new Object();
}
public String getString() {
return "Hello World";
}
}
And here's the services.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<service name="test">
<parameter name="ServiceClass" locked="false">
TestService
</parameter>
<operation name="getArrayOfStrings">
<messageReceiver
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
<operation name="getInt">
<messageReceiver
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
<operation name="getObject">
<messageReceiver
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
<operation name="getString">
<messageReceiver
class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" />
</operation>
</service>
And the listing of my .aar file:
% jar -tf test.aar
META-INF/
META-INF/MANIFEST.MF
META-INF/services.xml
src/
src/TestService.java
TestService.class
I started Tomcat (and thus Axis2) from scratch, with only the default
'version' service and then used the web admin CGI to upload the
service. Immediately, I saw the following in the catalina.out:
- Error in schema generating null

But yet Axis2 is still able to generate a WSDL (which I won't bother to paste).
Calling http://localhost:7070/axis2/services/test/getInt results in a
"resource not found" error, with no accompanying stack trace or error
messaging in my catalina.out.
When I try to call getInt() (or any other method, for that matter) via
a Perl SOAP client, I get the exception pasted below. Can anyone see
what it is that I'm doing wrong?
