如何监视Java控制台应用程序？

Question

I want to ensure that a java console application is running fine 24/7. It is just a plain jar, no application server involved.

The things I want to monitor externally should be:

• the console app is actually running
• the database connection is alive
• any webservice connections are alive (the app is mainly a soap client)
• some statistics on eg CPU
• cron jobs are running

There are several servlet applications that provide those metrics when running on an application server. But what about my case where it's just a cmd application? How could I expose those tasks to external tools?

Why not just use Jetty to allow your app to serve up a status page on demand? Or some JSON if you want it parseable by some other service?
