By Gene De Lisa | Published: May 15, 2011

I’d be rich if I had a dollar for each time I heard someone ask “How do I dynamically populate a drop down menu based on the current selection in another drop down?” Actually that is probably the poster child usage of AJAX. You can certainly use raw AJAX to accomplish this (just ask the [...]

By Gene De Lisa | Published: December 29, 2008

That’s right. Struts 1. Not hip. Not happenin’. But in the real world you might have bills to pay and a pair-programmer to feed. The docs are a bit sketchy with Spring 2.5 stuff. First you set up your service layer in web.xml 1 2 3 4 5 6 7 8 9 <context-param> <description>Used by [...]
