Re: [Wrapper-user] Cant get a thread-dump

[miken <mik...@gm...>]

Hi there,

I'm interested in option 1. Does anybody have a simple example showing how
to use requestThreadDump()? Especially, how to log on to the JMX console if
there's a form based authentication mechanism (which will rely on a database
to provide user / role information) in place.

Thanks for your help in advance,

Mike
