I haven't seen performance problems that would differentiate Java from any other platform in quite some time. Eclipse and VS.NET run about the same when it comes to responsiveness. jGnash runs as fast as GnuCash or even Quicken for that matter.

I haven't run NetBeans in a long time so I cannot comment about that. Eclipse runs slower on Linux than Windows but Gantt Project, Umlet and Visual Paradigm run about the same. Curiously enough, Poseidon runs much slower on Linux than Windows.

Poseidon for UML does that.

I don't understand the people who say it's difficult to use, from the template perspective all you do is put a dollar sign ($) and a bean name with a dot and then the field name (minus the get)... I.E. if your bean looks like this... public class foo { public String getBar() } then in your template to display the string returned by bar you'd just put $foo.bar that's it, no or nonsense. There are a few conditionals #if #else...and a #foreach construct as well as the ability to set values also, but, the greatest thing about it is it's simplicity. Well, that's my twenty cents.

Poseidon for UML Community Edition from Gentleware is a really nice modeling and reverse-engineering tool. It's Java-based (a *tad* slow on startup) and has great support.

It is a little rough around the edges and really needs some fine tunning but runs like a dream on my PowerBook running on JAVA 1.3 no less. With any luck they will upgrade it to use the 1.4 code base they are already using for Windows and Linux clients. It is quite resource intensive, however on the Powerbook I don't notice that at all (just on the Windows development machine at work ~sigh~).

I forgot to mention Emacs and JDEE. :-)

Setting up JDEE to get all the features can be somewhat intimidating, but worth it. You'll get features like intelligent code completition, easy lookup in the jdk or your own documentation, integration with ant (jdee can parse build.xml and provide completition on build targets etc.) etc. For modelling, I'm trying out Poseidon UML, which is, AFAIK, based on ArgoUML. (And it is a java app, so it runs on Linux, which I use on my workstation)

Look harder ... please :)

Poseidon for UML from Gentleware is quite a good UML diagramming package that has a 'Community Edition' available. It is written in JAVA and does require quite a good machine although the only ones I have worked with it on are ...

• Windows NT 4.0; 850 Mhz PIII w/ 256Mb RAM
• Windows XP; 1.2 Ghz Athlon w/ 512Mb RAM
• OSX 10.2; 1 Ghz G4 w/ 512 Mb RAM

That said, I don't use the latest version, so it might be better now.

Name 10 applications written in Java that can be bought at the store.

I believe he was talking about business systems (database clients and like ilk). Java clients have been quite successful in that area, there are tons.

Even so, I'm going to give it a shot, just for fun.

Dammit, just five, and using developer tools was kind of cheating.

• 100% java
• BSD licence
• only a few UML v1.3 features not (yet) supported
• import/export from/to Rational Rose using XMI are not (yet) totally working but a third party tool exists to do the translation (can't recall the name)
• SVG output (!)
• you can add all the plugins you want/need on top of the core app (MOF metamodel and GEF graphical framework)
• commercial support provided by Gentleware (if you've got a PHB to convince)

Poseiden for UML from gentleware is a commercial tool that evolved from ArgoUML. There is a free version (Community Edition) of Poseidon that is very effective for beginning users.
