NullPointerException while array serialization (Axis2.1.1)
Ladies and gentlemen, hi
I tryed to check how do I expose service returning array with Axis2.1.1 (I'm a complitely newbie with Axis2.1.1). I changed a standard Axis sample sample.addressbook.service.AddressBookService service:
public Entry findEntry(String name)
to
public Entry[] findEntry(String name)
{ return new Entry[] { new Entry(), new Entry()}; }
and the rest left the same. During invocation of deployed service I receive the error:
----------------------------------
<soapenv:Fault><faultcode>soapenv:Client</faultcode>
<faultstring>java.lang.NullPointerException</faultstring>
<detail><Exception>org.apache.axis2.AxisFault: java.lang.NullPointerException;
nested exception is:
org.apache.axiom.om.OMException: java.lang.NullPointerException
at org.apache.axis2.AxisFault.makeFault(AxisFault.java:318)
at org.apache.axis2.rpc.receivers.RPCMessageReceiver.invokeBusinessLogic(RPCMessageReceiver.java:136)
at org.apache.axis2.receivers.AbstractInOutSyncMessageReceiver.receive(AbstractInOutSyncMessageReceiver.java:37)
at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:454)
----------------------------------------
What is my mistake, please?

Hi
I did same code change to findEntry method of AddressBookService,
and packed this service to aar and deploy it to tomcat5.
But it worked.
I checked this with REST.
http://localhost:8080/axis2/rest/AddressBookService/findEntry?name=xyz
I got response like this,
<ns:findEntryResponse xmlns:ns="http://service.addressbook.sample/xsd">
<ns:return>
<city xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://entry.addressbook.sample/xsd" nil:nil="true" />
<name xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://entry.addressbook.sample/xsd" nil:nil="true" />
<postalCode xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://entry.addressbook.sample/xsd" nil:nil="true" />
<state xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://entry.addressbook.sample/xsd" nil:nil="true" />
<street xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://entry.addressbook.sample/xsd" nil:nil="true" />
</ns:return>
<ns:return>
<city xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://entry.addressbook.sample/xsd" nil:nil="true" />
<name xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://entry.addressbook.sample/xsd" nil:nil="true" />
<postalCode xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://entry.addressbook.sample/xsd" nil:nil="true" />
<state xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://entry.addressbook.sample/xsd" nil:nil="true" />
<street xmlns:nil="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://entry.addressbook.sample/xsd" nil:nil="true" />
</ns:return>
</ns:findEntryResponse>
I'm using Axis2 1.1 release with Tomcat5 on sdk 1.4.2, WindowsXP.
I think your code change will work.
