I have been working with the Swing library for a long time, I'm working on a new project for school and due to the nature of the program it can't look like a generic/boring swing gui. So my question is does anyone know of an interesting java gui library that is not swing or awt? ...
The documentation for ant's task states: The performance of the depend task is dependent on a number of factors such as class relationship complexity and how many class files are out of date. The decision about whether it is cheaper to just recompile all classes or to use the depend task will depend on the size of your...
I have to implement Java.Polynomial as a school assignment. Part of the methods are add(polynomial), multiply(polynomial) etc. In the case of something like p.add(q); // computes p + q is it better to return void and keep the sum of the polynomials in p? or is it better to return a polynomial and keep the former value of p intact? M...
Does anyone have links and resources to connect to an AS400 from Java? I remember years ago, somebody told me about a connector that simulates KeyStrokes from the keyboard and other "purest" approach that connected directly. On the web I have found a lot of links, but I cannot find a complete product to do this (I am probably not usin...

We've got a legacy app to support. It's pure JSP, i.e. JSP opens connections, does business logic, submits forms (usually to the same JSP), and so on. It's 400+ pages, with some pages are as large as 100K. The app is expected to be extended and modified over the next few years, so we're looking into ways to split presentation and busine...

I'm using the FlexGantt Javax Swing package (http://www.dlsc.com/) to display some Gantt charts. The trouble I'm having is that I can't figure out how to change the color of a DefaultTimelineObject that I've extended into my own class. Actually, about the only colors I seem able to change are the ones that are for the background colors o...
Running into an issue where JSF is filling up our sessions. We had a system crash the other day. Sent the Heap to IBM for review and found that we had some sessions as large as 50M. They found JSF components in the session and some very large. So, is there any tuning that can be done? Configuration items to look at? Or other directi...

I want to do that so that my version on Java doesn't override other versions on the PCs. ...
