[logback-user] Joran errors I don't understand

[ralph.goers @dslextreme.com]

The JMS and Socket appenders in Logback do not allow you to specify an
encoder. If you want to do that you need to add a getter and setter for
that to your version of the JMSQueueAppender. However, if you really want a
String instead of a byte array you can just as easily use a Layout instead
of an encoder.
