We have a generated webservice based on WSDL using JAX-RPC, in WSDL we have response like below 

```
<element name="notificationsResponse">
<complexType>
<sequence>
<element name="Ack" type="xsd:boolean"/>
</sequence>
</complexType>
</element>
</schema>

```

Even the generated code has the method return type as Boolean 

```
public boolean notificationXXXXX(java.lang.String XXXX,
            java.lang.String XXXX, java.lang.String XXXX)

```

But when we invoke the service from Soap UI, we are seeing the response 'Ack' as 0, 1 not as true / false. This was working fine with JAX-WS.

Any help on this is highly appreciated
