AW: Java 2 compatibility

Hi Scott,

I don't think that's the main problem here: there's no need to rewrite the management GUI to use the java2 api; having 1.1.8 as a requirement for building the gui should be acceptable.

The resulting java application actualy does start on JRE other than 1.1.8, but will fail for some operations; this makes it very hard to use the web-plugin version of the GUI for example.

I've just started the management GUI under JRE 1.3.1/IE6.0 under windows. Startup/login works fine, I can watch the failsafe console, but if I (for example) klick on the cluster-icon to open the cluster properties window, an exception occurs.(*) see below

Fixing/avoiding these and so allowing the GUI to run under current JRE versions should not be a big rewrite but rather fairly localized changes.

Bye, Martin
