[Wrapper-user] Auto registration of Java Service Wrapper MBean

[<nic...@uk...>]

Hi,

With embedded JMX server in JDK1.5, it would be really nice if Java Service
Wrapper could auto-register its JMX bean (upon jdk1.5 detection).
This is especially so when using the WrapperStartStopApp and
WrapperSimpleApp integration methods.

Below is the code/config I have written to register JMX beans using the
WrapperStartStopApp integration means.

It would be much nicer if it was built into the wrapper itself - and
enabled via a wrapper.conf parameter
wrapper.jmx.enable=true
wrapper.jmx.name="wrapper:type=Java Service Wrapper Control"

Its a fantastic utility by the way. Documentation is excellent. Its
well-baked. It Just Works. ;-)

Cheers,
Nick
