Subject [jira] Commented: (AXIS2-4722) NPE Thrown When Enabling the UDP Listener Globally
Date Sat, 22 May 2010 06:50:16 GMT

    [ https://issues.apache.org/jira/browse/AXIS2-4722?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12870280#action_12870280
] 

Amila Chinthaka Suriarachchi commented on AXIS2-4722:
-----------------------------------------------------

I did not go through the code. But I think transport like SMTP, UDP, TCP should always configured
at the service level.

if you configure the UDP in global level how you going to dispatch the service?

As I remember earlier Axis2 smtp transport uses one global address and used an header to dispatch
service. But that was not a standard way.

> Steps to reproduce:
> 1. Enable the UDP listener in the axis2.xml by adding the following entry:
>     <transportReceiver name="udp" class="org.apache.axis2.transport.udp.UDPListener">
>         <parameter name="transport.udp.port">9999</parameter>
>         <parameter name="transport.udp.contentType">text/xml</parameter>
>     </transportReceiver>
> 2. Start the server and following NPE will be thrown:
> 2010-05-20 16:02:43,890 [-] [main] ERROR ListenerManager Couldn't initialize the udptransport
listener
> java.lang.NullPointerException

> 	at samples.util.SampleAxis2Server.startServer(SampleAxis2Server.java:61)
> 	at samples.util.SampleAxis2Server.main(SampleAxis2Server.java:40)
> I was able to reproduce this issue with Synapse and the sample Axis2 server that comes
with Synapse. I will soon attach a patch.
