> <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 org.apache.axis2.transport.base.datagram.AbstractDatagramTransportListener.startEndpoint(AbstractDatagramTransportListener.java:75)
> at org.apache.axis2.transport.base.datagram.AbstractDatagramTransportListener.startEndpoint(AbstractDatagramTransportListener.java:31)
