List the open source projects that impress you heavily (not limit to Jakarta)?

[Doug Wang]

The role of open source projects becomes more and more significant in our industry. I cant live without them even one day. I will list some of them(related to Java and XML) here.

Apache Project - a HTTP server all over the world

Jakarta Project, including Tomcat, Struts, ant, cactus ...

Apache XML Project - 50% of Java application is related to XML

JUnit - we are discussing it here

Project JXTA - will lead the p2p era

Eclipse Project - bring us brand new IDE with allowing plug-ins and its built-in XP features

Netbeans Project - Another IDE project conducted by SUN

Squeak Project - A marvelous IDE written by Smalltalk (not Java )

Could you please add something on this list or give your comments?

I have been using DBVisualizer from Minq software. It is a Java DB management tool. I realize it is not an open source tool but it is free and very good. I thought it was worth mentioning.

I would like to add CVS For NT as a replacement to Sourcesafe and PVCS. The default model calls for allowing multiple checkouts but there are commands (admin -l and edit -c ) which let you use it in a fashion similar to VSS and PVCS.
I am also using PostGres along with cygwin (a Unix emulator for windows) as a robust and scalabe database for small and medium non critical apps.
For a nice source editor I cannot live without I would recomend Crimson Editor (free not open source).

[William Brogden]

I think Cocoon is going to be exceptionally significant as a web publishing/content management tool. It is part of the Apache XML project but is drawing in contributions from all over.

Apache Apache Apache. If only they would multithread it.

[Gagan Indus]

www.sourceforge.net
www.freshmeat.net are also worth pondering
( part of http://www.osdn.com/ n/w )
although not opensource by deifinition , IBM alphaworks sites also have some good stuff
http://www.alphaworks.ibm.com/
http://www.sunsource.net/ lists few open source projects with weight

[Gagan Indus]

soz !
noticed we are discussing here projects n not sites !
ok JDOM is the one i ll like to mention
www.jdom.org

[Rick Hightower]

I am a really big fan of the Jakarta project and JBoss.
For Jakarts... I've used everything from Log4J to Struts.
I think if you are doing JSP/Servlets than Struts is the next logical step.

[Doug Wang]

Thanks for all your inputs. We've got a wonderful list. I hope the game will go on.
I like Python, so JPython should be added.
If Nick would suggest one, I guess he might mention aspectJ.
Nick, how do you view the future of AOP? Is AOP a design technique or a new programming paradigm? Could you pls talk something about your recent research on aspectJ? Thanks.

[shailesh sonavadekar]

doug , as far as aop is considred , the guru Grady Booch himself says it as " Disruptive Technology on Horizon. "
it is not programming technique. it is improvement over oo technology . rather you can say technology which can solve the problems which oops can not solve. so , to use it you first need the solid foundation in oo technology. then , only you can realize the problems oo technology can not solve.
if you read the papers from the developers of this technology ( XEROX PARC ) , probably that will give you more insight.
i hope this helps.
REgards.

I am very impressed with Ant. Struts has been useful as well.

[Joe Gilvary]

Let me cast a vote for MySQL.
And let us not forget Linux!

There is a huge hype about Eclipse by IBM. has anybody worked on it, any feed back?

[jayram]

add www.mozilla.org to the list. Its not directly related to java but it would prove to be a great help for revival of client side java
then there is axis.
cheers

yes. me. I like it very much. It is easy to use, but you must read the first tutorial in the help perspective. I really hate to read tutorials about computer programs, but this one was really fast. Then you have a for me very usefull Java ide. Give it a try!!!
It is the basis for IBM WebSphere Application Designer (comercial).
Problem: at the moment no gui builder available. But 3.rd parties can build modules. And will do so. As IBM.
Its not that clumpsy as forte.

struts and ant! struts and ant! struts and ant!
the world is a better place for these 2
Also a plug for mySQL-Front - since i'm not all that databasey it quickens up my development time no end!
Any opensource project that gets me away from the screen and outside (...to the pub, usually) is good and the 3 above do that

[Shin Hashitani]

Hi everyone,
Wow, this posting is really cool.
I also hope this list to grow. I'll definitely try some of those.
Anyway, argoUML is my pick:
http://argouml.tigris.org/
I have not contributed anything, but I really want to in near future. This app is a lifesaver.
Oh, I haven't tried yet, but I hear good things about Enhydra:
http://www.enhydra.org/
Enhydra sounds like a thing between Servlet and EJB. I hope I can have some fun with it in near future.
Not an open source, but some free stuff:
EJBGen:
http://beust.com/ejbgen/
By implementing document based keyword, this tool generates Home/Remote interfaces and dd for WebLogic.
Java2HTML:
http://www.vaegar.f9.co.uk/java2html.html
very easy to use souce-to-html converter. It prints out frame-based HTML files for display.

[Junilu Lacar]

Bias aside, ALL of the Jakarta projects.
I'm surprised that nobody has mentioned Log4j specifically.
Some other ones you might to check out as well:
Cactus - JUnit extension for server-side testing
Commons - has the very useful Digester class
Lucene - search engine

and arch4j

[Junilu Lacar]

In the same category as MySQL and PostgreSQL, there is also HypersonicSQL

[Shuai Liu]

Familiar Linux!
An embedded Linux for handheld devices such as iPaq. I just begin to use it and it is really good. Also, those developpers are very nice and helpful.

[Doug Wang]

Hi Liu Shuai,
Thanks for your vote. Seems that guys agree on the rule of giving the home address while recommending a project.
So supplement here: handhelds.org is the home of the Familiar Project.
