property is set for a service which sends back a response message
---------------------------------------------------------------------------------------------------------------------------------------------
Key: ESBJAVA-437
URL: http://wso2.org/jira/browse/ESBJAVA-437
Project: WSO2 ESB
Issue Type: Bug
Affects Versions: 1.6
Environment: Ubuntu7.04, JDK1.5.0_14, Firefox 2.0.0.12
Reporter: Evanthika Amarasiri
Assignee: Upul Godage
Below are the steps to reproduce the error
1. Created a proxy service as follows
<syn:proxy name="proxy_sample" transports="https http jms"
startOnLoad="true" statistics="enable" trace="enable">
<syn:target>
<syn:inSequence>
<syn:property name="OUT_ONLY" value="true"/>
<syn:send>
<syn:endpoint>
<syn:address
uri="jms:/Adding?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://localhost:61616&transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&transport.jms.DestinationType=queue"/>
</syn:endpoint>
</syn:send>
</syn:inSequence>
<syn:outSequence>
<syn:send/>
</syn:outSequence>
</syn:target>
<syn:publishWSDL uri="http://localhost:9000/services/Adding?wsdl"/>
</syn:proxy>
2. The service which is invoked here is a simple service which accepts two
numbers and returns the value after adding the two values.
3. Once the request is sent the simple axis2 server throws a
NullPointerException as below and the response is not sent to the client
