Axis No Serializer Found error...

[Finn MacCool]

I am trying to invoke a webservice passing in a custom java bean object, which I have "beanmapped" in the deploy.wsdd but I keep getting the No serializer found for class ... in registry org.apache.axis.encoding.TypeMappingDelegate@e70e30 axis fault.

Java code snippet:

Request request = new Request();
...
Service service = new Service();
 
Call call = (Call)service.createCall();
call.setTargetEndpointAddress(new java.net.URL(endpointURL));
call.setOperationName(operation);
call.addParameter("arg1", new QName("Request", "local"), ParameterMode.IN);
call.setReturnType(new QName("Response", "local"));
 
Response response = (Response)call.invoke(new Object[] {request});

The deploy.wsdd:

<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<service name="myWebservice" provider="java:RPC">
<parameter name="className" value="com.test.webservice"/>
<parameter name="allowedMethods" value="retrieveData"/>
<beanMapping qname="ns:local" xmlns:ns="Request" languageSpecificType="java:com.test.messaging.Request"/>
<beanMapping qname="ns:local" xmlns:ns="Response" languageSpecificType="java:com.test.messaging.Response"/>
</service>
</deployment>

Does it mention the correct class name in the exception, i.e. what is the full error message?

Is the class in the classpath on both sides?

Sorry, I just cut it off to shorten it. It does mention the correct class name. Here is the full error message:

The webservice is just local and I have the class in a jar in the axis lib folder as well.
