So I just stumbled into doing this little trick. It may go against some pattern, or best practice, but I’m sure there’s a use for it somewhere. In Struts 1.3 (and probably any Struts 1.x), it is sometimes useful to have a request chain across multiple Action classes, maybe to break them up into more [...]
Finally, Java can switch on Strings! No more inefficient strings of if/else chains or Hash lookups or translation into Enums. Finally just clean readable and intuitive code. switch(suit) { case "club": case "diamond": trickValue = 20; break; case "heart": case "spade": trickValue = 30; break; case "no-trump": trickValue = 40; break; } It’s actually just [...]

This [...]
With the Wicket Java Web framework where a lot of magic happens behind the scenes, and almost no XML needs to be configured. Most of it is done with Java. It has a lot of pretty cool features. I just came across this one. In the init setup of your class that extends WebApplication, you [...]

List<String> strings = Arrays.asList(foo","bar");
