Open Source and Java Packages

Ok. I'm creating an open source massively multiplayer role-playing game. A game, basically. Me and my team are trying to figure out what package to make the root. It was suggested that we use "org.fiverings" (Five Rings being the name of the game, for now), but we don't own the fiverings.org domain name. Now, one of our team has argued that if someone else buys that domain name, then we are invading their space, and could get into major legal issues.
So how are we supposed to choose a root package name? Are there any conventions dealing with this? We're doing the project on SourceForge (you can get to the hosted page at <http://fiveringsrpg.sourceforge.net>), and so does that mean that we can extend SourceForge's package (like: net.sourceforge.fiveringsrpg)? Or, because we don't exactly own that domain, are we restricted?
Thanks to any replies on conventions, and thanks to all that check out the game and post something in our non-Dev forum.

for commercial projects it is common to use
com.company.product....
replace com with org/net or stateprefix if u wish.
But you could also start with any other prefix. And you can always change this afterwards (if you use sth like Forte For Java then the IDE can handle this renaming of packages without changing code by hand).
And I dont think, that when u use org.fiverings, that the owners of fiverings.org could put a legal on u.

Help needed regarding some open source and good media streaming server

Hi
I am searching for some open source and java based media streaming server which can facilitate live video streaming. Can anyone please suggest me some good streaming server.
Thank you.

Some observations:
(1) The use of the Configuration.createRootApplicationModule() API is recommended only for console programs, not web applications, but it should work ok as long as your use of the appliation module is completely stateless (which from the code it looks like it is since you release the AM back to the pool on each request.)
(2) You mention "Stateful" mode, but Configuration.createRootApplicationModule() only supports stateless mode, so you are effectively using Stateless mode.
(3) You are passing true as the 2nd argument to Configuration.releaseRootApplicationModule() which means you are asking to immediately remove the application module instance from the pool. This will hurt the scalability of your application since each request will need to be served by creating a brand new instance of the application module.
(4) You are explicitly calling disconnect(). This is not necessary.
I would recommend:
(1) Changing your 2nd argument to releaseRootApplicationModule() to false
(2) Remove the explicit call to disconnect()
(3) Given your usage pattern, I'd recommend calling viewobject.setForwardOnly(true) before calling viewobject.executeQuery() and iterating over the results. This will avoid any caching of the fetched view object results. Also ensure you've read section "27.2 Tuning Your View Objects for Best Performance" of the ADF Developer's Guide for Forms/4GL Developers guide on the ADF Learning Center at http://www.oracle.com/technology/products/adf/learnadf.html for more performance tips
For example, if you are fetching 65 rows, make sure the fetch size of this view object is at least 66 so you can retried all the rows in one DB roundtrip.

Logging with whereabouts using open source and freeware

You can find the html version of this at:
http://www.acelet.com/whitepaper/loggingWithWhereabouts.html
Logging with whereabouts using open source and freeware
The purpose of logging is to find out what had happened when needed. When the
time comes to read log messages, you want to know both the log message and its
whereabouts (class name, method name, file name and line number). So you need
to hard code whereabouts.
But hard coded whereabouts are very difficult to maintain: when you modify your
source code, line number changes; when you copy and paste a line, its class name
and method name change. If whereabouts are wrong, you introduce bugs in your logging
logic and the log messages are useless at the best.
This article shows you an example of using freeware Redress tool to rectify whereabouts
programmatically in your Makefile or Ant build file. So your whereabouts are always
correct for both Java and JSP source file.
Redress tool is part of SuperLogging at http://www.ACElet.com. SuperLogging also
provides an open source wrapper Alog.java, which redirects log method calls to
your favorite logging package. Redress tool can rectify whereabouts information
on all Alog's method calls in your application. So, if you call Alog's log methods,
these calls will be rectified by Redress.
JDK 1.4 introduces a new utility package java.util.logging. The example in this
article is based on JDK logging. Log4J is a cousin of JDK logging. Log4J users
should have no difficulties to modify this example for Log4J. Both JDK logging
and Log4J are excellent logging software for single JVM.
Note: Redress tool rectifies method calls on Alog, not JDK logging. You need to
call Alog instead of JDK logging in your application.
Source code of Alog.java

Hi;
I found this code and would like to share it with you :
JCoDestination destination = JCoDestinationManager

if (function == null)
throw new RuntimeException("RFC_FUNCTION_SEARCH not found in SAP.");
function.getImportParameterList().setValue("FUNCNAME", "*");
function.getImportParameterList().setValue("GROUPNAME", "*");
try {
function.execute(destination);
JCoTable funcDetailsTable = function.getTableParameterList()
.getTable("FUNCTIONS");
int totalNoFunc = funcDetailsTable.getNumRows();
if (totalNoFunc > 0) {
for (int i = 0; i < totalNoFunc; i++) {
System.out.println("Function Name: "

} catch (AbapException e) {
System.out.println(e.toString());
return;
System.out.println("RFC_FUNCTION_SEARCH finished");
It is working and retrieving FM.

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.

ATI Radeon drivers problems (both open-source and proprietary)

Hi 2 All!!
I have a problem with my ATI Radeon 9000-series. The open source drivers (xf86-video-ati) don't work very good for me, my monitor's fresh rate isn't "at-top" and the monitor projection is slightly translated to the right (say 8-12 pixels). So I've tried to build the official drivers with ABS, all is gone successfully, except for some worrying warnings, but I thought that it's normal. I have a customized kernel, build through ABS... So, when I've tried to load the fglrx module it says:
# modprobe fglrx
FATAL: Error inserting fglrx (/lib/modules/2.6.27-ARCH/video/fglrx.ko): Cannot allocate memory
Please, help me! My machine is slow, I can't run any OpenGL-accelerated application, even Quake III!!! If you can suggest me how to improve the performance and how to resolve problems with open-source drivers, it also would be very good... Thank you and sorry for my poor English please.

I had some problems with installing ATI drivers recently (could not build fglrx module, not even manually, I had to change some installation script), but with latest driver version (8.11 I think) from ati.amd.com was everything fine (I have Radeon 9600 Pro)
Try to do this (and write here the output)
glxinfo | grep vendor
fglrxinfo
In both cases, it should write something like OpenGL...: ATI... if there will be MESA or DRI, that means that you don't have loaded your fglrx module.
If fglrxinfo output will be something like: no permission for...(should be first or second line of the output), then write this somewhere in your xorg.conf:
Section "DRI"
Mode 0666
EndSection
run:
modprobe -a fglrx - and give here the output. If there will be none, run:
lsmod | grep fglrx - to see wheter fglrx module is really loaded in kernel
if you will have no module, you can install one, type:
cd /lib/modules/fglrx/build_mod
sh make.sh
cd ../
sh make_install.sh (as root)
and post any warning or error here at forum, drivers (but not fglrx module) are installed at /usr/share/ati
After installing drivers, you also need to configure your system (notice your system that it's there), commands:
aticonfig --initial (for editing your xorg.conf)
aticonfig --overlay-type=Xv (acceleration support in xorg.conf)
Showing your xorg.conf file here is also good idea, here is mine (sections Device and Screen):

Portal development with open source and without any of the Oracle products

Hi would like to know whether is there is any portal framework (pure java) available to develop portal application where I can integrate JSF, RICHFACES, GWT and .NET applications. I dont want to use any of the oracle products. Please help

You come to an Oracle specific forum and ask whether or not you someone can recommend you a portal product without needing oracle technology...
Sorry but that does not exist because java is also oracle so if you want a portal without wanting to use oracle than you will have to go for .net or php or something like that because java is oracle...
Don't you think it's a bit odd asking such a question on the official Oracle forums? It's like going into a BMW garage and asking if you can have a free car that has nothing of the BMW technology inside...
oh wait... 1 April, damn...

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 thought it was straightforward and I didn't feel that lawyers were necessary. But you didn't seem to want to do that."
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.

Java source and class locked, unable to drop or replace

Because Oracle 9i does not come with an FTP implementation, I installed the apache.commons.net package into the database, and implemented static java wrappers to allow me to publish the code.
After thoroughly testing the code under JDeveloper, I deployed the code to the database.
The code hung, establising a lock on one or more classes. Besides not knowing how to debug and java packages inside the Oracle database (eg, why did the code fail in the first place?), I have no idea how to unlock the source or class of my java objects.
How does one find what process is locking the java source and/oir class?

Try something like:
select s.username, pr.pid, pr.spid from
x$kglpn p, x$kglob o, v$process pr, v$session s
where p.kglpnhdl = o.kglhdadr
and pr.addr = s.paddr
and p.kglpnuse = s.saddr
and o.kglnaobj = dbms_java.shortname('fully/qualified/ClassName');

Drop java class and java source

Hi,
When I query user_objects I get some java class and java source objects
select * from user_objects where object_type like 'JAVA %';
How do I drop these java source and java class objects from the database
I tried using the following command
drop java class /4a524d89_AutoTransliteratorPk
drop java source AutoTransliteratorPkg
But I get error ORA-29501: invalid or missing Java source, class, or resource name
Please someone help me in dropping these objects
thanks

was the java source all caps or was it exactly AutoTransliteratorPkg. If its exactly AutoTransliteratorPkg then try this
drop java source "AutoTransliteratorPkg"

How do we create self-signed certificate using java packages

Hi All,
I require some information on creating self-signed certificate using java packages.
The java.security.cert.* package allows you to read Certificates from an existing store or a file etc. but there is no way to generate one afresh. See CertificateFactory and Certificate classes. Even after loading a certificate you cannot regenerate some of its fields to embed the new public key – and hence regenerate the fingerprints etc. – and mention a new DN. Essentially, I see no way from java to self-sign a certificate that embeds a public key that I have already generated.
I want to do the equivalent of ‘keytool –selfcert’ from java code. Please note that I am not trying to do this by using the keytool command line option – it is always a bad choice to execute external process from the java code – but if no other ways are found then I have to fall back on it.
Regards,
Chandra

I require some information on creating self-signed certificate using java packages. Its not possible because JCE/JCA doesn't have implementation of X509Certificate. For that you have to use any other JCE Provider e.g. BouncyCastle, IAIK, Assembla and etc.
I'm giving you sample code for producing self-signed certificate using IAIK JCE. Note that IAIK JCE is not free. But you can use BouncyCastle its open source and free.

�Is Sun System Instant Messaging a Multiplatform Open Source Application?

This Because I am searching a highly Compatible Open Source WEB Enable Client/Server Application or a robust Multiplaform Instant Messaging System for Academic Purposes.
I searching to obtain a WEB Enable Instant Messaging Application Open Source in Java like MSN Messenger Client/Server for Academic Purposes?
I find Jabber as an alternative Instant Messaging solution but the clients and servers Applications there aren't highly compatibles.
I thank in advance for their valuable time. And for the attention and the collaboration lent me.

I believe there are currently two open source J2EE 1.3 compliant appservers:
JOnAs http://jonas.objectweb.org/
JBoss http://www.jboss.org/
Both have beta versions of their J2EE 1.4 offers. If what you are looking for is not actually open source but simply free as in beer, then Sun's appserver is a rather attractive option. It's already J2EE 1.4 certified because it is the J2EE 1.4 reference implementation. You can download it as part of the J2EE SDK from here http://java.sun.com/j2ee/1.4/download-sdk.html

Open source / Commercial version, it's up to you! Why not for ESB products

Please comment this forum and help us to get Sun's support for Open ESB as we can get it for open-Solaris or Glassfish.
Thanks
Paul

http://www.pymma.com/eng/People/Blog-Paul-Perez-Chief-Architect
Jonathan Schwartz new policy
Few years ago, Jonathan Schwartz replaced Scott McNealy as SUN Microsystems CEO. Swartz's first decision was to convert Sun into an Open-Source company. Consequently, Solaris OS, Application Servers and even the Java language were opened and their sources published. At present, Sun is viewed as a major Open Source actor.
Sun�s new sales philosophy proposes, on one hand, its best products in an open-source format and on the other hand, commercial support and hardware. The best examples of this new philosophy are Open-Solaris and Glassfish. You can download these products, use them and test them. After you have built applications with these tools and wish to move into a production environment, you can buy support from Sun.
Open source or Commercial version, it's up to you!
Alternatively, you can as well buy commercial versions at the first place. Even if open sources and commercial versions are slightly different than the open-source ones, more than 95% of their code is originated from the same development branch. Example : SUN proposes its queue messaging system with two similar versions, respectively named �SUN QM� and "Open-MQ". The only difference is the amount you pay for the technical support.
Everyone can find advantages in this sales policy on Sun products: companies and developers try and develop for free and can rely on Sun support in production. As a matter of fact, Sun uses these �free� products as Trojan horses to conquer new market shares, penetrate new companies and sell Sun hardware.
Why not for ESB Products ?
Unfortunately, there is a small issue in this picture: Sun's ESB platform is the exception in this sales policy. In Fact, Sun proposes two different tools for ESB developments. The first product. "JCAPS", is a commercial product inherited from Seebeyond. The second product, "Open-ESB" is based on JBI specifications (JSR 208) and was developed from scratch about 2 years ago.
Alas, JCAPs and Open-ESB are definitely two different products.
JCAPS ignores JBI specifications
JCAPS connectors are based on JCA specifications and not on JBI.
Open-ESB development process is based on Web services specifications, JCAPS not.
JCAPS and Open-ESB developments are not compatible.
Hundreds other differences can be found between the two products.
We can understand that for a while, for technical, marketing or business reasons, a company supports more than one product lines with the same functionalities. IBM does it and Oracle buying BEA will do it also.
However, there are several things that Pymma would like to understand:
Why the download of JCAPS is only available for authorized JCAPS Partner ?
Why SUN does not provide support for open-ESB as it does for Glassfish, Open Solaris or Open MQ ?
Why JBI or Open-ESB are never mentioned at most ESB seminars organized by Sun Centres in the UK ?
Why Sun marketing, Gurus or consultants are prolix about JBI in the public lectures and technical forums, and at the same ignore Open-ESB when they advice companies ?
Is the policy of Jonathan Swartz policy only applicable for Java Legacy applications (Application Server, Message queuing�)? not for ESB tools ?
Of course, we already asked these questions to SUN but we never got clear answers.
Thanks for clarifying Sun's position
Many companies believe in JBI and their developers spend time and energy working on Open-ESB . These companies would certainly be interested to hear Sun's explanations on the above questions. They probably want to be sure that Open-ESB will not be just a prototype for the new JCAP version (only reserved for SUN JCAPS Partners). They certainly want to be credible by proposing SUN's professional support on Open-ESB as they do for Glassfish and Open-Solaris. After, they only need from SUN to clarify its position and give a clear prospective for the future of JBI and Open-ESB. We hope that through this blog Sun will hear us and we will give us clear answers.

Hi Leonie,
My iPhoto is iPhoto 11, version 9.4.2. I believe my Aperture is the latest version but I don't know how to verify that when I can't open it. I regularly accept any updates.
How I restored my Aperture Library: I opened Aperture, clicked on Time Machine, and navigated to the Aperture Library that had been backed-up earlier in the day. It took a while to restore.
When done, I opened Aperture (yes, at that point I could still open it). It opened up on the still-empty Library, and I had to manually change it to the restored library, every time I opened aperture after that. This was annoying, so, I then went to FINDER and deleted the empty Library. I probably shouldn't have done this; I noticed it had the words "current default" in its filename.
From that point on, FINDER shows the restored aperture library (actually two restored aperture libraries, since I accessed Time Machine a second time to restore an even older backed-up version) but of course, not the empty Library that had had "default" in its filename. And... I can no longer open Aperture.
Hope you can help me, thanks so much,
Glensdaughter

Open Source Video Chat

Open Source Video Chat
After thousands of questions and forum posts, we decided to release the RVC project open source. RVC is a random video chat (aka. chat roulette) software, includes audio, video and text data streaming over both Cirrus – real time media flow protocol (RTMFP) by ©Adobe Labs – and the open source Red5 media server (RTMP). Most custom made chat roulette websites are powered by or built on RVC 4+ source code.
Project home
The project is hosted at Google Code: http://code.google.com/p/video-chat/
SVN, use: svn checkout http://video-chat.googlecode.com/svn/trunk/ video-chat-read-only
Source Code
Latest (up to date) source code can be found here (download packages may be weeks older):
https://video-chat.googlecode.com/svn/trunk/
The developers, site owners and forum members, who worked close with us, may remember, we did not stop the development since the first release (Feb. 28, 2010); we will further develop RVC Open Source and kindly ask you to join us with posting your ideas and contribution in order to create a better random video chat that is available to everyone, for free.

Hi,
I'm in the same situation. Do you ever found a solution? I only need direct communication, point to point, chatrooms or something are not needed but nice to have.
Skype is not a solution neither is Google Hangouts.
I came across Mumble. I thought at first you can create channels for yourself on public servers but unfortunately not. Most servers won't allow you to create a channel for yourself. So your best bet here is to run your own server (which means additional expenses for me).
Ekiga seems nice but there is no iOS client.
The closest thing so far is Linphone, which has clients for Linux and iOS, but you need a SIP account somewhere.
Any experiences with this?
Thanks for any input.

Is JSF technology based on open source?

Hi,
Does any one know if JSF is based on any open source technology? Like struts?
Because my company projects use Struts technology, they want to switch to other
non-open source technology, does JSF suit for this purpose?
Thanks for your valuable advice,
Raymond

Most of Java itself is Open Source. The JSF API is open source and can be found at https://javaserverfaces-sources.dev.java.net and as BalusC mentioned, you can access Mojarra's source code as well from there. The MyFaces implementation is also open source.
Does your company want something that is not open source? Or do they want something they can count on with a company to stand behind it? A product with real release cycles and a person they can call for support? If that's what they really want, JSF is a good choice. Particularly if you choose GlassFish (which includes JSF) -- or more likely the Sun Java Systems Application Server version: http://www.sun.com/software/products/appsrvr/index.xml) which is fully supported by Sun MIcrosystems. This should give your company the confidence they need in a fully supported product. BTW, there are tools and other supported products (portal, access manager, JBI, etc.) that integrate very well with this solution if you need them. Check it out.
Good luck!

Don't give up just because there are other options out there.
Adobe is only giving up the free tool for education purposes, or unemployed developer. You didn't say if you were one of those.
I believe over time there will be plenty of room for alternate IDE approaches that support the Flex Framework; and in fact there are quite a few options already out there.
