settter/getter is OK for simple data types,
but for Arrays (or Lists ?) it does not really
update XMBeans attributes under JBoss server.
For example, it is OK if I update an array type
of attribute by jmx-console from JBoss,
but it failed (I mean that it is shown updated in the
screen, but it does not really update the XMbean
persistent XML file) if through JManage.
