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.
