cvs commit: jakarta-commons/modeler/src/java/org/apache/commons/modeler/ant MLETTask.java JmxSet.java JmxInvoke.java
costin 2002/11/12 14:46:09
Added: modeler/src/java/org/apache/commons/modeler/ant
MLETTask.java JmxSet.java JmxInvoke.java
Log:
A couple of generic ant tasks for JMX support.
( they could be added to ant 'proper', but it's better to keep
them here as a taglib ).
Just basic and experimental stuff right now - it works for me.
