Scratch your Groovy itch on the web

Here is a web based Groovy console, so the next time you are say on the train and want to write some Groovy using your iPhone* or at some PC with a locked down environment, you can!

Hours of fun or your money back :-p

* Nope, never wanted to write Groovy on the train either, but you never know.

Update from a former colleague of mine:

BTW, this is hosted on Google App engine, which only recently started supporting Java! There still seem to be some issues, I can’t execute code like System.properties{e,k->println e} due to some security exceptions. Similalry File based code also seems to be violating some google App Engin security.

Useful JMX Connection Troubleshooting blog

Here http://blogs.sun.com/jmxetc/entry/troubleshooting_connection_problems_in_jconsole

Links to ones pages I know about, like the JMX faq but also to other pages.  There is a bunch of other config values and tips there.

I found it useful because it explained (or least linked to) explanations of how the TCP connections back to the client work on a random port.
