[Wrapper-user] Newbie - Integration with program that does Thread.sleep

[Berg, I. M. \(Ivan\) <iva...@av...>]

Hey all,

FYI, not on the mailing list, so please reply directly to

Just started using the wrapper, looks like a nice program, so thanks for
the hard work putting it together.

I am a newbie trying to integrate into a java watchdog program that:
a. Starts up and does some initialization (very quick)
b. Polls to get a status (success/fail)
c. Goes to sleep via Thread.sleep for a time period. Usually > 30
seconds
d. Wakes up and polls again, might do some action based on this
e. Rinse, repeat
=20
I tried to integrate via Method 1, but it looks like the sleep is
messing up with the health checking with the JSW.

I set the following:
#  Number of seconds to allow between the wrapper pinging the JVM and
the response
wrapper.ping.timeout=3D60
=20
But it didn't seem to have much affect

Got something like:
2005-05-17 09:55:26,040 [main] DEBUG WatchDog  - Sleeping for 30 seconds
Waiting to start...
Waiting to start...
Waiting to start...
Waiting to start...
Waiting to start...
Startup failed: Timed out waiting for a signal from the JVM.

------------------------------------------------------------------------
Advice:
The Wrapper consists of a native component as well as a set of classes
which run within the JVM that it launches.  The Java component of the
Wrapper must be initialized promptly after the JVM is launched or the
Wrapper will timeout, as just happened.  Most likely the main class
specified in the Wrapper configuration file is not correctly
initializing
the Wrapper classes:
    AICWatchDog
While it is possible to do so manually, the Wrapper ships with helper
classes to make this initialization processes automatic.
Please review the integration section of the Wrapper's documentation
for the various methods which can be employed to launch an application
within the Wrapper:

JVM did not exit on request, terminated

So, I was looking for some advice, is there something I can play with in
the config parameters to handle this better?=20
Will moving to integration Method 3 help?=20
Any other ideas?

Thanks, Ivan
