Dear all
Catalina ant task <jmx:set> sets only one mbean attribute
My improvement proposes to set several attributes by using
<jmx:attribute> sun-elements
The MBeanServer.setAttributes(ObjectName name,AttributeList
attributes)
method is used instead of the MBeanServer.setAttribute(ObjectName
name,Attribute attribute) method
Modified files are in attachment and modified and new code lines are
bracketed between // ADDED comments
My ICLA is signed and I'm a contributor of Felix (Apache incubated
project).
Kind regards
Didier
PS: I hope to post this mail to the right mailing list ! I did not
seen
Tomcat in https://issues.apache.org/jira/secure/BrowseProject.jspa
