User: schaefera
Date: 01/06/25 22:29:13
Modified: src/main/org/jboss/jmx/server XMLAdaptorImpl.java
XMLTestService.java
Added: src/main/org/jboss/jmx/server XMLAdaptor.dtd
Log:
Added all the major methods to the XML Adaptor which make sense. I also
added a DTD for the XML file but it is only Alpha release.
