Open source applications runnig on WLS

Does anyone know or have statistics of any OS or GNU busniess type applications (sorry I know this not a good description) that run or are running WLS.
I am participating in a building management system XiBMS application that runs on Jboss. I would consider altering the build process to make a version to run on WLS but would the developers contributing to the project be expected to shell out for licenses? If I remember correctly WLS comes with a limited developer license (limit on number of connections) but is there anything else I should be aware of?

I don't really understand your first question, but you might want to look at Beehive (http://incubator.apache.org/beehive). It is an Apache project that runs on WebLogic (as well as other servers), although it is a framework (not sure if that qualifies as a "business type application")
Yes. Development licenses are free (with the restrictions you are aware of). You can even download the BEA Platform for development purposes at http://www.freetodevelop.com
You only have to pay for deployment licenses.

Porting open source application to SAP WAS

Hi,
I'm porting jZForum ( http://www.jzforum.org ) to integrate it with SAP WAS and SAP Dictionary instead of internally used
HypersonicSQL database. I mainly changed obtaining connection to the database directly through JDBC:
jdbc:hsqldb:hsql://localhost:1476
into connection obtained through JNDI with Spring Framework (more precisely through org.springframework.jndi.JndiObjectFactoryBean class) :
jdbc/MY_DATABASE
with connection pooling parameters:
initial connections: 1
maximum connections: 50
maximum time to wait for connection: 120
expiration: yes
connection lifetime: 600
cleanup thread: 300
Unfortunately ported jzForum seems to "hang on". I see in Log Viewer (Visual Administrator) log that it is quering database with a lot of SELECTs,
I assume that it is indexer which on startup is indexing all objects from the forum to speed up searching this objects in the future.
After about 2-3 minutes hanging on, application shows generated page, but every subsequent request to
the server cause hanging on in the same way.
I assume that it might be the case that application is obtaining through JNDI connection to the database, but is
not releasing it. I have examined entire jzForum code, and closed all unnecesary Connection in final Java statements,
but it unfortunately didn't help.
Original jzForum (not ported to SAP Dictionary) works on SAP WAS just perfectly.
Have someone else experience with porting open source application from some database (eg. HSQL) to SAP Dictionary ?
Maybe it is a problem with Spring Framework implementation ? Maybe it is a problem with wrongly configured connection pool ?
I have no idea at the moment. Every help will be appreciated.
Kind regards,
Marcin Zduniak

Hi Marcin,
from what you are describing, the port to JNDI obtained connections and your "research" in visual admin uncovered some issues with the original code ( not closing open connection ).
My attempt to explain your difficulties:
1. Working with hsqldb in direct mode, where hsqldb connection are obtained by driver.getConnection(), works well, becuse GC "reclaims" unused but not closed
connections. Things seems to work out this way.
2. Getting connections through JNDI involves a datasource with its associated db pool. Not closed connections are then "trapped" in the pool as long as is specified by the "connection lifetime" DS parameter. Things get worse by the time, becuse the application leaks constantly connections.
Remedy for the problems described in 2:
- middle term: fix the application: here spring might be useful, consider using its JDBC support classes!
- short term: set the connection lifetime to a small value to let pool reclaim the unclosed connections
Hope it helps a bit,
Gregor

�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

X11 and open source applications issues

I have a brand new iMac 20 w/ OS X 10.4.8/ Core Duo 2.16/ ATI X1600 w/ 256 mb vram/ 1 gb of system ram. I have been using open source systems for almost two years and would like to continue to use some of the applications which are provided for Macintosh. When attempting to install any of the X11 applications, I get a message saying that I need to have X11 installed in order to install and run the apps. I downloaded the Apple X11 1.0 installer because I did not see X11 on my system. When trying to install it, I got a message saying that it could not be installed because there is a more up to date version already installed.
So, the installers for applications such as, Open office and Gimp Shop, do not see that I actually have X11 installed and they will not install because of it. I do not know enough about OS X to work through this issue.
Any help will be greatly appreciated.
Thanks,
zeusx64

I did not see another version of X11 but I did go into the installation of the optional items and did not see it listed. I am fairly well versed in using computers, so I am not a complete noob but I am fairly new to Mac itself.
I have FreeBSD experience, which in itself, gives a bit of X11 experience.
That said, I have already looked for needed packages to install, tried to install and as I said before, I recieved the message during the attempted install of X11, which said I already had a more up to date version installed.
If I have by chance missed something along the way, feel free to provide a link to the needed package.
I am open to learning all that I can and realize that we all are in a never ending process of that learning.
Thanks for the replies and I hope we can figure out what I have not on my own.
I will check my mail when I am at home after work.
Thanks again.

Open Source Applications ? List them?

Is it possible to submit your app to the AppStore as a GNU licensed
open source app? It must be, because WordPress have done it. The GPL
is included in their Xcode project file here:
http://iphone.wordpress.org/
But I am wondering how they did it?
Did they need to do any special lobbying etc, to get it through?
I previously thought you couldn't publish open source through AppStore.
Are there any others?
Let's make a list of open source iPhone apps in this thread!

You couldn't release open source due to the old NDA that has since been lifted. "Barcodes" is an app i've seen recently say it was open source.

Open Source AIR App Wanted

I'm not sure if this is the right forum but I am looking for
AIR developers who might be interested in creating an open source
application based on the Tweetworks API. Call it Tweetworks
desktop. I think it would be a great project for the AIR developer
community.
Here is a link to the API:

Hi I have added the following to my application.xml file
<x>0</x>
<y>0</y>
The application now open is the top left hand corner of the screen but I would like it to open to the top right hand side of the screen.
I also need to make the application sit on top of other windows
How do I do this?

Viewing open source code

I would like to know a website or book that I can actually see the source code that has been developed for the Java open source code. This would help me tremendously in understanding how everything is put together. Does anyone know of this source?

That would vary from application to application. You talk as if there is one "Java Open Source" application out there that we could point you to the source of. Of course there are many many many different applications out there, and there isn't one answer for you.

I am using UPK developer 12.1.0 single user. My sofware has crashed and needs reinstallation. Please suggest how can I take back up of my source files. I am unable to open the application and i can not locate the library backup folder on my local machine.

Combine supported files is not automatically opening and closing source applications?

On my Vista 64 machine, suddenly, the "Combine supported files in Acrobat" has begun malfunctioning. Instead of automatically opening and closing the source application (such as MS Word), Acrobat opens the application and then asks to save a new PDF file for each source file and stalls out the conversion. This problem is not happening on my Win XP machine. I have used the 'Repair Acrobat Installation' function but the problem is not corrected.
Thanks for any suggestions.

Just to close out this thread, the bug was fixed with the latest version of Acrobat Pro Extended (9.3.3).

Can I distribute the open source SWF compiler with my application?

I'm unclear reading the documentation if there is a difference between Adobe's official Flex SDK, and the open source version?
Can I distribute the open source SWF compiler with my application?
I have a flash application that users can change the fonts being displayed, if they supply the fonts in a compiled SWF. I found I can let the user select a font from their computer system, and using the mxmlc command I can easily generate a SWF with the font, which can be loaded by my application so the font will be part of the run time application when played on systems without that font already in the System fonts.
I was wondering if I could distribute the open source SDK so that I could compile these font SWFs for the user so they would not have to get involved in complicated Flash development. The audience is non Flash audience.
I tried using SWFMill but the fonts don't seem to work as they do with the mxmlc compile.
Thank you,
Scott Kerr

Moreover check also the compatibility of your open source license with MPL

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 Sourcing an iPhone Application acceptable under the License Agreement?

I've read through the licensing agreement, but I'm still not convinced either way. I want to make my iPhone application's source code available on the internet and set up a project page and SVN repository on a site such as Google Code. I wouldn't be distributing my signing keys and would be the single source for submitting the app to iTunes. Is this allowed under the License Agreement?

(Disclaimer: IANAL, I'm just a smart guy who's worked on GPL projects.)
That isn't the relevant part of the iPhone license agreement. The GPLv2 (which is probably the most important open source license for this question, as it's both very popular and has restrictions on mixing with proprietary code) does not encompass headers and libraries that are part of the operating system. That's how people can write open source Windows and Mac applications--believe me, Microsoft would not be pleased if someone contacted them and said that since Gaim was open source, they had to release the source code to the Win32 API. So the GPLv2 would not attempt to "annex" anything provided by Apple, and thus it wouldn't violate that section.
What may be relevant is the iPhone license section concerning confidentiality. If the class, method, function and constant names are considered "Apple Confidential Information", you would be in violation of the contract if you distributed code that revealed them. I rather suspect that nothing in the Foundation or Core Foundation frameworks could be considered confidential, as information about them is freely available to anyone who has the Mac OS X Core Library, which is distributed with every copy of Leopard. UIKit, Core Location, etc. are another story; I personally think that the fact that the APIs are included in the free SDK ought to preclude considering them confidential, but Apple might think differently.
In other words: you're definitely safe using LGPLv2 libraries. If the code would also compile with the Mac OS X SDK, you're almost certainly safe releasing it under the GPLv2*. If the code uses UIKit or other frameworks documented in the free SDK, you may be safe releasing it under the GPLv2. If you release any code that uses APIs that only licensed developers have access to under the GPLv2, you're probably totally screwed.
The GPLv3 is much stricter, and so the story there might be different; for example, I think it may have key-releasing requirements that would conflict with the contract. I don't really know much about it, though.
\* Remember, the original copyright holder can create alternate licensing arrangements for specific people. So he can say "anyone can use this code under the GPL, and as a special exception, it can be linked against FooCorp's non-GPL software". But to use anyone else's GPL code, you'd have to get all of the authors of that code to agree to the same exception. Alternately, you can just release your own code under the LGPL instead and then it's all good.

Need information on open source testing tools for ADF web applications

Hi experts,
I need to investigate on new feasible open source Java testing tools for testing ADF web applications. I have tried to google a lot but getting confused.
My requirements as as under:
1. The tool must be open source.
2. It should be easy to understand and to work upon by the tester and developers.
Selenium based testing approach is already in place for testing the application but need to search for tools other than Selenium which shall prove suitable for testing ADF applications. Kindly let me know your inputs / suggestions.
Thanks a lot in advance.

Hi,
Have a look at JMeter http://jakarta.apache.org/jmeter/index.html
1. The tool must be open source.It is.
2. It should be easy to understand and to work upon by the tester and developers.I guess it is.
There are some specifics in configuring it for ADF, but Chris Muir wrote a nice blog about how it's done, check it out http://one-size-doesnt-fit-all.blogspot.com/2010/04/configuring-apache-jmeter-specifically.html

I haven't tried ICEFaces or JBoss seam or Apache MyFaces, so I can't really compare them.
ICEFaces appears to be a nice framework/tool from looking at their site, even though it's open source I think one has to pay for support, you might want to take that into consideration while making your decision.
Apache MyFaces, is fully community driven - so you get free support from the community.
I don't know about JBoss seam.

Employ open source framework to existing web application

Hi everyone,
Existing application model:
MySQL, Tomcat, Java 6 SE, so no EJB.
Own MVC model used (no framework).
Own data access layer model (no framework).
Because this is a corporate application, the UI experience
can not be broken (in terms of new beautifuly deployed pages
vs old existing pages - developed around 8 years ago). Application
run on balanced Tomcats, so it's getting more and more difficult
to synchronize all information.
Question:
Is there a way of smooth transition from own developed MVC
and DAO to open source frameworks to leverage some of the work
required to do manually as it is currently, like validation,
access like hibernate instead of manual creation of DAO objects ... ?
Also, it would be nice to have some reach user interface framework
employed but I don't know how it would be achieved not to break
the look and feel (all pages would have to be done at the same time,
and we are talking here about hundrets of existing screens developed
in different technologies).
Application consists of few millions of lines - so it's a real challange.
Thanks for all tips.
