I am able to connect to IBM MQ using the steps mentioned here. But when Flume is trying to consume any messages from the Q, its throwing following exception.   com.ibm.msg.client.jms.DetailedMessageFormatExcept​ion: JMSCC0053: An exception occurred deserializing a message, exception: 'java.lang.ClassNotFoundException: null class'. It was not possible to deserialize the message because of the exception shown.   1) I am using all the ibm mq client jars. Flume is starting with out any exception. But exception is coming when trying to consume the messages . 2) I am putting a custom message [Serializable object] into Q which Flume need to consume. 3) Flume 1.5.0-cdh5.4.1 4) MQ Version 8.x   a1.sources=fe_s1 a1.channels=c1 a1.sinks=k1 a1.sources.s1.type=jms a1.sources.s1.channels=c1 a1.sources.s1.initialContextFactory=com.sun.jndi.f​scontext.RefFSContextFactory a1.sources.s1.connectionFactory=FLUME_CF a1.sources.s1.destinationName=MY.Q a1.sources.s1.providerURL=file:///home/JNDI-Direct​ory a1.sources.s1.destinationType=QUEUE a1.sources.s1.transportType=1 a1.sources.s1.userName=mqm a1.sources.s1.batchSize=1 a1.channels.c1.type=memory a1.channels.c1.capacity=10000 a1.channels.c1.transactionCapacity=100 a1.sinks.k1.type=logger a1.sinks.k1.channel=c1   ...
