Dendrogram built-in JAVA function? Open-source?

Hello,
I have been searching the internet for a way to use dendrograms with data that I have generated. A dendrogram looks like this: http://www-csli.stanford.edu/~schuetze/dendrogram.html
And supposidly there is a class in JAVA to do dendrograms. I was wondering if anyone could give me a little more insight into how this is done.

Thanx.

Possibly Antoine Chalubert could. But why not download the package and try it out for yourself?

Is Java itself open source?

Hi,
There are a lot of software built using JAVA are open source.
But is JAVA itself open source?
Thanks.

What is YOUR definition of open source?When someone says "open source", they probably mean it as you can see it defined on Wikipedia:
"...source code is available under a copyright license that permits users to study, change, and improve the software, and to redistribute it in modified or unmodified form."
I have seen talk of open-sourcing Java in the media for a long time, and searching Google yields many results.

Java GUI open source components ?

Hi guys;
I'm writing a desktop Java Application that I'm planning to sell later on.
The point is that I want the GUI to look sharp : so I don't plan to use the Ugly looking java Swings.
the look I'm looking for might be close to MS office 2003 or even better.
I wonder if there are some FREE OPEN SOURCE java GUI components that I can integrate into my code ?
Please let me know if you have any Ideas about this issue .
Many thanks for your precious Help !

Try this:
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());That attempts to set swing's L&F to one which matches the OS you're running it on.

Why is it good for java to be open source?

if java becomes open source, will people take java, put viruses into it and send it to people?
i have use red unix and it is not as good as windows, though it does have its uses for calulcations, but why would we want java to go down this road?

Stop trolling, "garish_shaboo".

CommunityDiscussion/Forum built in Java......

Good Afternoon,
I need a tool for creating community discussions and searched google, sourceforge, etc for one built in Java. I found the one used here called Jive that was originally an open source project. The Jive open source page was moved to the jivesoftware site where you can buy it. I like what is offered by Jive and would not mind paying the $1500 bucks or so for the license. But, if there is open source I would much rather contribute source code contributions than bucks.
Does anyone know of a similar tool written in Java and open source? Or not open source? One key feature is allowing a user to see only those forums they are authorized to see.
Many Thanks!
Al

Hi Kevin,
Unfortunately, no. I found a few and most were in early stages of development with really basic features. There are some good ones, but not in Java.
We have settled on Jive and will be coughing up the bucks. It seems to be worth it.

Legalities of modifying open source Java classes in a closed source App

If there is a better forum for this thread please let me know. I looked and looked and couldn't find any place where it seemed to fit.
Simply put, I want to know the legal ramifications of modifying open source Java classes which have been included in a commercial closed source application.
The specifics are my problem with the javax.servlet.http.Cookie classes interpretation with RFC 2019 in regards to acceptable cookie names. I currently am debating that in a thread here:
http://forums.sun.com/thread.jspa?threadID=5313146
I am using Adobe ColdFusion which is a J2EE application server running as a servlet in Macromedia JRun. JRun parses request headers and creates instances of the javax.servlet.http.Cookie class for each cookie. (An error is thrown from the constructor if the cookie name is not accepted)
I was able to work around the problem by modifying the code in the Cookie class, compiling it, and using jar.exe util in my SDK to update the new class into the jrun.jar file. I blogged it here:
http://www.codersrevolution.com/index.cfm/2008/7/15/No-Cookie-For-You-Second-Solution
My problem is I'm not sure if what I did conforms to the license for ColdFusion. Technically JRun is a closed source program I am not allowed to modify, but all I changed was a open source class from Sun. I didn't even need to decompile anything.
I have Googled in vain, but I can't seem to find any information that applies to modifying pieces of open sourced code contained inside of a closed source application.

I'm unclear on whether you are implying that I didn't want to hire a lawyer or that I didn't want to read the licenses myself and make a decision. If you meant the former, you're darn right. I'm not paying anyone a dime to satisfy my personal acedemic curiosity concerning a random project I've been messing with in my spare time that isn't related to to any job or business decision. I'm simply looking for information because that's I do when I don't understand how something works. First, I Google the hell out of it and if I can't turn up satisfactory answers (or any at all) I find an applicable forum and ask there.
If you were implying the latter (that I didn't want to read the licenses myself) then you haven't been reading my posts. I stated to jschell that I have no problem attempting to figure out a license agreement on my own. In fact, I have read the ColdFusion agreement from Adobe before posting here. I talks about modifying the software, but I still don't think it is crystal clear about whether third part code falls under it's own license AND Adobie's or just its own license. Then that is the point at which you must do one of the following
1. Consult a lawyer.
2. Decide to allow for a liberal interpretation (thus you can use the code) and understand that you personally are liable if your interpretation is wrong.
3. Decide to allow for a conservative intepretation to avoid liable on your part.
Regardless of what anyone says here it won't remove your own liability.
>
The source for the java.servlet.http.Cookie class stated that it is release under the Apache license 2.0 whcih I read up on. I will admit I'm not actually sure how to tell the exact verison of the Java Servlet API classes that JRun is built on other than to cross reference which version of the servlet API came out with which version of Java, but that is a suspect method. I have been programming for more than 8 years, but I'm relatively new to the Java landscape.
I'm not looking for handouts here. I know this was a tough subject and I was prepared for NO ONE to respond and I would have been ok with that. I have no problems making decisions on my own and I have no intention of passing the buck to anybody.
Here's the thing though. A useful response is one that states some facts (or opinions), references a similar peice of software for comparison, a court case, or provides a few links to some open source-type websites were I might find more information about my issue.
Telling me to hire a lawyer and chastising me for "pass the buck" is doing about as much good as Linux snobs telling people to RTFM.
Wrong.
A lawyer is the best and most correct answer.
And it is the first answer that should always be given with these sorts of questions.
If you choose not to accept the best and most correct answer then that is up to you.
I understand that a large number of people on public forums are lazy sponges who wish someone would just post all the code they need, but assure you I am not that person. I'll admit I don't know much about open source and I'm not sure where to start looking since I seem to have a scenario which is not really discussed much on the web. All I am looking for is information and sincere help.And presumably you also understand that we certainly can't give you legal advice but also it would be foolhardy for you to accept it as well.
You learn by reading many license agreements and reading as much about legal situations involving computers and related technical cases as you can.
And until you are comfortable making such decisions yourself without asking then the only useful answer is ask a lawyer.

Do I need to pay anything to Adobe if I inject java script using some open source library?

Hello,
I want to restrict PDF reader to achieve Digital Rights Management (DRM).
Do I need to pay anything to Adobe if I inject java script to achieve so using some open source library?
Basically I want my PDF documents to be restricted such that I can:
Limit printing
Prevent screenshots
Restrict access by license expiry date
Restrict distribution of downloaded PDF (i.e. the document should run on specific machine only)
Restrict copy and paste within PDF document
I came across below links from which I suspect Adobe expects one to pay if he/she attempts to restrict reader functionality in some way?
http://www.adobe.com/devnet/reader/topic_drm.html
http://www.adobe.com/devnet/acrobat/overview.html
Am I correct in my assumption?

I think it is a vain hope to imagine you could implement DRM via JavaScript. Remember it can be turned off.
Printing is either enabled or disabled according to document security.
Working with PDFs does not require permission from Adobe but
* adding functionality to Adobe Reader definitely does; a DRM development license is a major investment.
* if the file is Reader-enabled, all third party tools will disable that.

New Open Source Project - Java, Struts, EJB

There is a new open source project called Centraview. This is an open source CRM/SFA application which can provide a business a full view of their enterprise from lead generation, sales, contact management, project management and integrate into accounting. The development has been going on for more than a year now and they've now taking this open source, so there is alot of opportunity for Java developers to get involved with project that really takes advantage of Java technology. The system is built on the Struts framework and utilizes JBoss as the EJB container, the back-end database is MySQL although there is some initiatives to look at DB abstraction. Anyway here's the link:
http://sourceforge.net/projects/centraview/
Anyway I decided after examining Centraview, that we're not going to be building our own, but using Centraview and it's nice to know we can take part in development and understand the inner workings, so we never limit ourselves.

Presumably you mean GUI and not web.
I have used AutoIt to drive GUI window applications.
[http://www.autoitscript.com/autoit3/]
Seemed pretty easy when I used it. It had a recorder.
On windows I believe you can also use "script host" and the newer powershell but I have used those.
You could also look at the java Robot class or whatever it is called.

I Need Information about Open Source Java Client/Server Instant Messaging

I need your valuable help and collaboration with the following issue:
I need to know where can find a robust Open Source Java Instant Messaging Client/Server Application.
I thank in advance for their valuable time. And for the attention and the collaboration lent to me.

I was going to mention that right off, but since the OP is clearly unaware of the search engines on the Web, I thought I'd give him a hand. Jabber works pretty good - I tried it a while back and some of the clients were ... quirky.

Open Source News group in java

Hi all
Not sure where to post this.I am looking for an open source news group one similar to java forums where users can post comments on my application and stuff.Is there anything of such kind which
is open source so that i can save time rewriting a similar one.I googled and tried some other sites but attempts were in vain.
thanks,
Sree

DrClap,
I see what you are saying but i don't think my company allows me to do that since its an in-house tool and i don't have much idea about how confidential they might consider posting
things on an external server.So i'm planning if i could get an open source project or library which does that i could provide the space and stuff needed for it to work.
thanks
Sree

JAVA ME version Open Source

I hope I can download this from ORACLE website and use this code as open source code. Is this correct?
Thanks & Regards,
Tushar

How about this ?

Open-source java polling/survey software??

Hello,
Does anyone know of a good open-source java polling software (web-based)?
Thanks in advance,
Julien.

javacardsign is a signing applet, and yes it tries to be pkcs15. With respect to opensc compatibility we still have to test and see what else remains to be done, but currently we have other priorities, so this will take time.
Regarding 7816 compatibility, you are absolutely right, this is too general. What is meant is that
a) the instruction set is iso7816-4
b) crypto operations are according iso7816-8
c) if personalised with our host application the file system contains iso7816-15 compliant structures
Cheers

Open source java desktop applications

Hi all,
Can someone direct me to a simple open sourced java desktop application (not from java tutorial).
I had no luck finding one myself. It seems to me there isn't many out there. I found open workbench but thats too complex for a beginner like me.
regards,
Sebastian

I had no luck finding one myself. It seems to me
there isn't many out there. You mean like Eclipse? I took me 1 ms to think of that one. I'm sure there are many, MANY more... Did you try Google?

OPEN SOURCE JAVA GAME

Hi, my name is Dydra and I have been programming an MMORPG in java this last two years. I want to publish an open source Java game to start a new generation of cross platform games, but I can´t do it by myself xD. So I want to share what I have done so far with everyone interested in programming games so that everyone can help making this game.
All the code is not mine: some parts are from the book Killer Programming Games. I adapted the 3D MMO engine of that book to an 2D engine and customized some things.
If anyone can tell me how to make this an open project here at sun forums, please tell me xD.
Here is a youtube link with the game working so far:
http://www.youtube.com/watch?v=CvNtx_pibwM
PM me or email me if interested: [email protected]

Do you know the best part? It is almost finished. The things that need to be finished are:
-Leveling up and stats (no big deal)
-GUI (like menus and invetaries. no big deal too)
-NPC (this may be the most complex part)
- Shop and Players Party/Trade
-Drops
THE REST OF THE GAME IS DONE! I already did a map editor with custom map objects and will be used to place Non Agressive NPCs. I also made a custom set up of menues and skills. To have a skill or item into the game you just need to open your wordpad and write the img file and what the item does (damage, heal, equip, instant spell, etc).
I need help to improve animation of the sprites, skills, improve the GUI ( I did it all myself but it's kinda crappy, you know) and the NPC. As I want it to be a PVP oriented game because there is no real RPG PVP oriented game. Most PVPs are MMOFPS like GunZ.
I eben have the host for the server! jajajajaj
Need your help guy!!!! Di you hear me!!!??? jajaja
Thanks for responding, I hope you'll join my PvP cause xD
