Oh, sorry. I should have included that I was specifying the -

<jvm-arg>-agentlib:jprofilerti=port=31758</jvm-arg> <!--this is

If you start Resin with the -verbose option, you'll see exactly the
command line options that the watchdog is launching the JVM with.
That should help debug this.
java -jar lib/resin.jar -verbose

I've also tried (among many variations):
<jvm-arg>-Xbootclasspath/a:agent.jar</jvm-arg>
<jvm-arg>-agentlib:jprofilerti=port=31758</jvm-arg> <!--this is
copied from a command launched via jprofiler directly that profiles-->
with agent.jar in the working directory.
Regardless, I still get a "Could not find agent library on the
library path or in the local directory: jprofilerti".
So, sounds like I'm doing what I should with the JVM args. The
command that the resin.jar file tries to launch dies quicker than I
can see what it actually tried to run (via ps) so I can't tell if
maybe some arg is being dropped.
Running java -jar lib/resin.jar results in the watchdog starting and
then a sub process being spawned to run the actual server. The jvm-
arg specified in the conf file get passed through untouched, but if
the command later includes a -Xbootclasspath:... then my change will
get squashed. At this point I am assuming that is what is happening.

After much investigation, here is where things stand...
Adding the options to the jvm-arg doesn't appear to work. The
resin.jar file appears to remove or supersede the required -
Xbootclasspath/a option needed to add the agent lib.
Can someone run me through how I might add a jar to the boot class
path? I think that is all that is missing.

I found the option in a mail thread.
Jprofiler is a commercial product. That option won't work unless
you've installed JProfiler. I think you can get an evaluation
license, but by all means you should consider forking over the cash
to buy the thing, or some other product. Commercial profilers are
way easier to operate (IMO) than the builtin stuff.
So I assume the -Xrunjprofiler option is garbage.
see above.
