Java 6 (Mustang) GA Release

Does anyone know when the Java 6 GA release is scheduled, if at all? I looked at the JSR but it appears they haven't gotten there yet. We have a 1.3 application, which I would really like to rewrite. I read that 1.3 will be EOL upon this release of Java 6.

According to https://jdk6.dev.java.net/ under the news section:
"Beta 2 is out! and we are heading towards final release in late October. See beta2 notes from Danny and Mark. [June 15, 2006]"
But as we all know, deadlines are made so that they can be missed.

Java Desktop System Release 3 - Login problems

Hi all,
This is my first post here so apologies if I'm in the wrong area. I've recently installed Solaris 10 (5.10 Generic_118833-36) onto a V245. I wanted to see if I could get the gui desktop to work so I downloaded/installed Hummingbird Exceed on to my Windows XP workstation. Having launched Exceed XDMCP broadcast I could see my host in the list so I selected and clicked OK. I was instantly presented with the blue login shell, so good so far. In options, sessions I chose Java Desktop System release 3. When I tried to login as root the login shell just dies and disappears but If I use a non-root account it takes me all the way in to the desktop gui. The same thing happens if I use select CDE as the session type as well.
So my question is how do you login as root?
I gues it's a config file somehwere that needs a tweak but I've not been able to find anything helpful on Goolge so far.
Any help is most appreciated.
Thanks
Jon Barker

I just removed the locales using the same tool and I can log in now.
Does anyone have any idea why this is or the correct way to install extra locales ?
Thanks

Reg : JA310 : Java Web Dynpro Release 640

Hello All,
I'm following the SAP's JA310 Java Web Dynpro Release 640 Documentation as part of my learning.
In this Documentation I found some examples in which it says to open an already existing project with a pre-defined structure.
I guess SAP may have provided some CD with solutions of the Exercises along with this documentation .
I don't have that CD.
If any of u guys have this then I request you to send the content of that CD to my Personnel mail id : <b>[email protected]</b>.
Thanks in advance for ur understanding.
Regards,
Deepu.K

Hi,
there is no solution CD for the JA310 course.
The mentioned "open an already existing project" describes the process
of importing the project while sitting in the class, having access to
the WTS-infrastructure of SAP during the course.

Michael

Java se zip release

Dear All,
Does anyone know why has been the java se zip release removed from the download section? Long ago it was a possibility for experts to download the whole jdk in one archive. I need it because I'd like to try the java 6, but I use java 5, and i don't want any trouble after a new jdk install. Is it possible to get jdk 6 as a zip?
thanks,
Gergely

There is a solution, but it's not pretty. You can use a hex editor to find all the cab headers in the file ("MSCF"), and extract the individual cabs from the downloaded executable. Each cab will contain a portion of the JDK. The most important one is the cab that contains tools.zip, because it contains the compiler and most of the libraries. You don't need to worry about the length of the cabs so you can just copy from the header to the end of the file. The extra data after the end of the cab will be ignored.
Like I said, not pretty or easy, but if you really wanted to do it that way...
Alternatively, just install on another machine and then copy it to your machine.

Java ME 8 Released!

Exciting news: Java ME 8 Released!
Best,
-- Terrence

Hi Travis,
Right, there is no UI API in ME8 except for Line UI. We've working on defining the proper API but currently cannot say what that would be. Sure it will not be MIDP 3 UI, it was dropped as not relevant for embedded. LWUIT? almost likely not. As you can see we put a serious effort in converging Java SE embedded and Java ME embedded, so there is high chance that UI APIs are converged as well

Hi,
There is know problem with Java Desktop System, Release 2:
If you log in using accessibility features on the Java
Desktop System for the Solaris platform, the following
error dialog might appear: Error activating XKB configuration.
How can I solve this problem? Can I disable accessibility features (especially when I log in using NoMachine NX Client)?
Thanks,

Uploading file with Java: Java won't release the file.

I'm trying to upload .log files to a webbsite using a form. It uploads fine, that's not the problem. The problem is that I want it to delete the file afterwards to save disk space, but the application doesn't release it. I thought I might just be doing something wrong with the delete function, but even deleting it manually through Windows doesn't work. Any ideas?

And you're closing the inputstream to the file?Thanks, I knew it was something simple like that but I'd been staring at it so long I couldn't see it. I guess a fresh pair of eyes helps.

Announce: Generic Algorithms for Java, 0.3 release

The latest release of jga: Generic Algorithms for Java is now available at
http://jga.sf.net/
Included in this release are a collection of algorithms adapted from STL that operate over generic collections and iterations. What's included are the algorithms that do not attempt to modify the collection/iteration that they're given: in other words, all of the find/search/count algorithms. Also included are the complete set of functors and predicates that were present in the last release, with a few modifications for easier use.
The library is released under the LGPL, and includes the source for the library, the test framework, and a non-genericized version of the test framework that verifies that the library may be used without having the generic environment available.

A (similar, it seems) parameterized collections library for JSR-14 Java.I had looked at JUtil some time ago, and I'm not sure of the similarity: JUtil looks to provide a number of interesting (if somewhat specialized) collections. JGA provides functors & predicates, and STL-ish algorithms that operate on collections and iterators. Looks to me to be more complimentary than similar.
Mr. Ananian/Astaire's site is also the source of SinjDoc, the javadoc tool that I used to generate the javadoc at jga.sf.net, and with which I replaced the munge4doc.pl and mungedoclist.pl scripts that I had previously used and posted on this forum.

When is Java going to release it's own perfume?

Given the current penchant for threads demanding that Java be afforded ever-more-unlikely and unnecessary extensions, for no reason other than somebody thought of it whilst on the toilet, and the other current trend for one to be a total nobody (apparently) until one has ones own brand of perfume, I'd like to know when Eau de Gosling or whatever will be released. Dukes for the funniest response. Maybe

Simple Java question about releasing beans from memory

Hi,
I use many beans in my app. Is there a way to release them from memory, or destroy the object. I feel that its possibly eating my memory up over time. Most of my beans are in page scope. Some are in session scope. So the page scope ones should kill them at the end of execution of the page and the session ones should delete the object from memory when at the last page of the app where session is no longer needed.
Someone mentioed System.exit(1); but I have not found any clear documentation that this will free up the memory that it has used.
Thanks for your time. It is appreciated.

There is no way to explicitly force the memory to be released. The JVM garbage collection will take care of it when more memory is required. The programmer's responsibility is to ensure that there are no remaining references to the object. System.exit() ends the JVM so you do not want to use that. You can call System.gc() to request that garbage collection runs, but the JVM does not guarantee that it will.

Java application not release memory

I have java 1.3 or 1.4, my application start correctly.
I have set heap a 4Mb but process java begin consume ram, initialy start with 7MB after 12-15 hour the process have above 60% system mem (128Mb).
After 16-18 hour kernel kill process.
I have Ubuntu distribution
Thanks

it is difficult to address this question without having a knowledge of the application. Here are some suggestions:
(1) run the application from within Java Studio in debug mode. This will give you an idea of what is absorbing the memory. The idea here is to be able to watch your data structures grow. Any tool that allows you to do this will help. See http://developers.sun.com/prodtech/javatools/jsenterprise/index.html
for Java Studio Enterprise.
(2) the chances are very good that your application is creating some sort of Collection (Set, Hashtable, Vector, ...) and slowly adding to it. This is very common and a common cause of "memory leak".
(3) The garbage collector in Java frees memory as objects go out of scope. If the objects never go out of scope, they are never garbage collected.
(4) If you have these such objects or collections that must always be accessable, consider adding some caching mechanism (putting the data to disk) whereby keeping your datastructures smaller.
(5)Also, when you say "set the heap" I am assuming you used the -Xmx and -Xms command line options. If not, look into these.

Jave 1.4 Release

Does anyone know how the 1.4 project is coming along, and when the JDK 1.4 and JRE will be released?
I remember the date being an approximate "mid September" ... just looking for an update!
thanks,
Andrew

I remember the date being an approximate "mid
September" ... just looking for an update!You must have been mistaken - that's when beta 2 was supposed to arrive (which it did, of course). The alpha version should be released sometime in the last quarter; likely before the christmas, that is :)
