NullPointerException thrown when the OUT_ONLY property is not set in the in
sequence when sending a request to a JMS endpoint
-----------------------------------------------------------------------------------------------------------------------------
Key: SYNAPSE-253
URL: https://issues.apache.org/jira/browse/SYNAPSE-253
Project: Synapse
Issue Type: Bug
Components: Transports
Affects Versions: 1.1.1
Environment: Ubuntu7.10, JDK1.5.0_14
Reporter: Evanthika Amarasiri
Was trying out the following configuration which sends a request to a JMS
endpoint.
***************************************************************************************************************
<syn:sequence name="jms_sequence">
<syn:in>
<syn:log level="full" separator=","/>
<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"/>
</syn:endpoint>
</syn:send>
</syn:in>
<syn:out>
<syn:log level="full" separator=","/>
<syn:header name="To"
value="jms:/NewAddingQueue?transport.jms.ConnectionFactoryJNDIName=QueueConnectionFactory&java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory&java.naming.provider.url=tcp://localhost:61616&transport.jms.DestinationType=queue"/>
<syn:log level="headers" separator=","/>
<syn:send/>
</syn:out>
</syn:sequence>
***************************************************************************************************************
Accidentally I forgot the set the property OUT_ONLY=true.
When executing the client a NullPointerException is thrown as below. Even
though you should specify this property when exposing services through JMS you
should not get a NullPointerException if a user forgets to include it in the
configuration.
