    For xml tracing you need to use <XmlTraceToStdout value="1" /> in the EmaConfig.xml file under the Channel Config e.g.

    		<Channel>
    			<Name value="Channel_2"/>
    			<ChannelType value="ChannelType::RSSL_SOCKET"/>
    			<CompressionType value="CompressionType::None"/>
    			<GuaranteedOutputBuffers value="5000"/>
    			<Host value="122.1.1.100"/>
    			<Port value="14002"/>
    			<XmlTraceToStdout value="1" />
    		</Channel>

    You should then see the Incoming and Outgoing messages on the std out.

    Obviously, you can redirect Std Out to a file using standard Java functionality e.g.

    try { 
    	System.setOut(new PrintStream(new BufferedOutputStream(new FileOutputStream("output.txt")))); 
    } catch (FileNotFoundException e) 
    { 
    	// TODO Auto-generated catch block e.printStackTrace(); 
    }

    Make sure that the application loads
    the configuration from EmaConfig.xml. For example:

    consumer = EmaFactory.createOmmConsumer(EmaFactory.createOmmConsumerConfig().consumerName("Consumer_2"));

    The snipped configuration xml:

    <ConsumerList>

    …

    <Consumer>

    <Name value="Consumer_2"/>

    <Channel value="Channel_2"/>

    <Dictionary
    value="Dictionary_2"/>

    </Consumer>

    </ConsumerList>

    …

    <ChannelList>

    …

    <Channel>

    <Name value="Channel_2"/>

    <XmlTraceToStdout
    value="1"/>

    <ChannelType value="ChannelType::RSSL_SOCKET"/>

    <CompressionType value="CompressionType::None"/>

    <GuaranteedOutputBuffers value="5000"/>

    <Host value="adsserver"/>

    <Port value="14002"/>

    </Channel>

    </ChannelList>
