Re: invoke jmxproxy servlet using argument with a , is not a possible

[Luis Rodríguez Fernández]

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.
