[jira] Commented: (AXIS2-1094) Throw NullPointerException when
invoking a service and return a customer JavaBean.
[ http://issues.apache.org/jira/browse/AXIS2-1094?page=comments#action_12434367 ]
Deepal Jayasinghe commented on AXIS2-1094:
------------------------------------------
I tested your sample in the current SVN and found that there is no problem in the server side , and you are getting the following response.
<ns:echoResponse xmlns:ns="http://service.test/xsd">
<ns:return>
<birth xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:nil="true" />
<ns:name>Eric Chow...BACKED</ns:name>
</ns:return>
</ns:echoResponse>
And I think which is correct , but now I am getting an exception in the client side . That is because according to the wsdl , it does not say that you can not have null value in the response. So if you change your service impl class as following you wont be getting any exception.
public User echo(User u) {
System.out.println("Receive: " + u.getName());
u.setBirth(Calendar.getInstance().getTime());
u.setName(u.getName() + "...BACKED");
return u;
}
