invoke jmxproxy servlet using argument with a , is not a possible
Hello
I am trying to invoke a mbean through jmxproxy servlet. Arguments are
separated with , so when one argument itself is containing a coma, it
breaks the invocation.
It seems there is no way to escape ,.
For example trying to save a context configuration fails :
curl -u user:pass -G "http://localhost:8080/manager/jmxproxy/"
--data-urlencode "invoke=Catalina:type=StoreConfig" --data-urlencode
"op=storeContext" --data-urlencode
"ps=Catalina:j2eeType=WebModule,name=//localhost/myContext,J2EEApplication=none,J2EEServer=none,true,true"
of course it works from jconsole.
(By the way as an alternative I tried
curl -u user:pass
http://localhost:8080/manager/text/save?path=/myContext but it fails with
FAIL - Encountered exception [javax.management.MBeanException: Cannot
find operation store] )

Hello Arnaud,
If jmxproxy does not work for you perhaps you can give a try to jolokia
[1]. It accepts JSON POST requests [2] that can implement your scenario.
The installation is quite straight-forward, simply deploy it as a .war or
attach it as an agent to your JVM.
Hope it helps,
Luis

splits
the parameters by comma and in your case it finds 5 parameters, while
StoreConfig#storeContext(String, boolean, boolean) expects 3 parameters.
Without improvements in the parsing code I think your case is not supported
at the moment.
