Hi Oliver,
Thanks for replying so quickly.
I tried out your suggestion and it works perfectly.
I've had a look at the CombinedConfiguration object and I managed to get it
working. I have added my code below.....is this the correct way to do this
or is there an even easier way to do it with CombinedConfiguration?
Cheers,
Brian
CombinedConfiguration cc = new CombinedConfiguration(new
OverrideCombiner());
cc.addConfiguration(masterConf);
cc.addConfiguration(localConf);
XMLConfiguration result = new XMLConfiguration();
result.setRootNode(cc.getRootNode());
XMLConfiguration finalResult = new XMLConfiguration(result);
finalResult.setRootElementName("IMConfig");
finalResult.save("resources/CombinedConfig.xml");
