URL: https://issues.apache.org/jira/browse/AXIS2-3731
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Environment: Win XP, Tomcat 5.0, Axis2 1.3, JRE 1.4.08, Axis 1.4 client
Reporter: Chinmoy Chakraborty
Priority: Minor
I got NPE when try to invoke service that return 3D object array. I am using
Axis 1.4 client.
Service class:
------------------------------------------------
package com.objectarray.service;
public class ReturnObjectArrayService {
public static Object[] returnObjectArray(String authToken) {
Object[] retVal = new Object[3];
Object[] args = new Object[3];
args[0] = new Object[] {"Arg1", "Arg2", "Arg3"};
args[1] = new Object[] {"Arg1", "Arg2", "Arg3"};
args[2] = new Object[] {"Arg1", "Arg2", "Arg3"};
retVal[0] = new Object[] {"RetVal1", "Retval2", authToken, args};
retVal[1] = new Object[] {"RetVal3", "Retval4", authToken, args};
retVal[2] = new Object[] {"RetVal5", "Retval6", authToken, args};
return retVal;
}
}
services.xml
---------------------------
<service name="return_object_array" targetNamespace="return_object_array">
<description>
This service is to get the array of objects
</description>
<schema schemaNamespace="return_object_array"/>
<parameter
name="ServiceClass">com.objectarray.service.ReturnObjectArrayService</parameter>
<operation name="returnObjectArray">
<messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver"
/>
</operation>
<module ref="soapmonitor"/>
</service>
axis 1.4 client code:
-----------------------------------
Service service = new Service();
Call call = (Call)service.createCall();
call.setTimeout(CALL_TIMEOUT);
call.setTargetEndpointAddress(wsServerUrl + "services/return_object_array");
call.setOperationName( new QName("return_object_array",
"returnObjectArray") );
call.addParameter("authToken", XMLType.XSD_STRING, ParameterMode.IN );
call.addParameter("reload", XMLType.XSD_BOOLEAN, ParameterMode.IN );
call.setReturnType(XMLType.SOAP_ARRAY);
Object[] Objs = (Object[])call.invoke(new Object[] {authToken, new
Boolean(reload)});
------------------------------------------------------------------------------------------------------------------------------------
In the SOAPMonitor I see Axis2 sends back fault string
<faultcode>sopeenv:Server</faultcode>
<faultstring>java.lang.NullPointerException</faultstring>
