Most common JRE version today?

I'm trying to develop an applet and I have trouble deciding on which version of the JRE to base it on.
I know of some machines still running JRE 1.4.2, perhaps due to enterprise IT policy. I was told the most common JRE I can assume to be the most widely deployed should be JRE 5.0 (1.5). And then JRE 6.0 the latest is already out since months ago.
Which option is the safest to ensure most users can run my applet successfully without having to upgrade/downgrade their JRE?
Thanks.

In my experience JRE1.4 is still quite in use.
On the other hand, Java 5 brings a lot of new and good stuff.
It's up to you to decide if you want/can live without the new stuff.

Most common Java Runtime used by Windows Users

I would like to know, what runtime environment is most commonly installed in Windows machines.
On my website I use applets, however, I do not know which version of Java to use. The latest version has close to zero users who have it installed - and i dont want to anger my visitors with PLEASE DOWNLOAD LATEST JAVA RUNTIME messages. however, what ive been using so far, 1.1.8, is positively ANCIENT!
i have been using that to be compatible with the MVM, but now i need additional features that come only 1.2 onwards... but do people have the JVMs for those versions?
which should be my target compilation for optimum results?
or should i just lump it and stick with 1.1.8?
bear in mind that my target consumer is the average browser who doesnt have any high tech knowledge/inclination
thanks

There are really too many considerations, but here's my take on it....
If you can write it to support 1.1.8 (although, technically, the MS JVM was really 1.1.4, but that won't matter much), then you could do that. Most of the people with the latest plugin versions will be using the plugin to run the applet anyway.
But if you have to do stuff with Swing and some of the newer API stuff for 1.2 or higher, then I personally don't think it's worth the hassle to include the swingall.jar for Swing in 1.1.8, or to try to write/find AWT components that are rich enough to mimic Swing. My feeling is that eventually, you have to move on, cut the cord, whatever.
IE/Windows isn't supposed to have the MS JVM anymore anyway. I haven't heard anything about MS putting it back in. Older systems (98, ME will, XP won't, especially after SP2) will still have it though. Netscape, Opera and Safari users will have to have the plugin anyway (except Netscape 4.x, which I hope no one's still using).
One of the bigger considerations tends (or tended) to be that the JRE/Plugin was a fairly large download. So for dial-up users, that's a problem. For broadband users, that's not a problem at all, and I think I recently saw an article claiming broadband has overtaken dial-up in the US. No idea about other countries though. As mentioned, it can be set up to auto-download and install.
If you are going to go with the plugin, stick with 1.4 for now, as more will have that then have upgraded to 1.5. Those that have, well, it won't matter.
And finally, a lot of PC manufacturers (Dell, certainly) have been installing the JRE 1.4 for the last 2 couple of years anyway.
Some people will certainly say that applets suck and aren't worth doing and there's no user support and all this stuff. Or tell you to try to use Flash, as the plugin has a larger install base.
Flash is certainly something usable, if you want to buy Flash. But there are things that Java can do that Flash can't. There are certainly things Flash is better at then Java applets. So it comes down to what the thing needs to do.

No JRE version found in launch file for this system

Hi,
I have an application which is launched by JWS.
When we use JWS from 1.4, it runs fine. But JWS from 1.5.0_15 gives the error "No JRE version found in launch file for this system"
In both the JWS(1.4 and 1.5.0_15)cases, we install JRE1.5.0_15 using the installer and used for invoking the application.
We invoke mailclient.jnlp, which inturn invokes the installer.jnlp and KanaJreInstaller.asp

We are using sun JRE(1.5.0_15) only. We extract Sun JRE and build it as KANAJRE.jar and signing.>I have never heard of KANAJRE. Would you care to post a link to the site, or should we just keep guessing? (My patience for random guesses is running out.)
>

Does it list it with the entire string "KANA1.5.0_15" or is is just listed as "1.5.0_15"?
Because this line from the JNLP file..
<j2se version="KANA1.5.0_15" href="KanaJreInstaller.asp"/>..had me convinved it was a non-Sun JRE. Not so much the href, but most especially the version attribute.
If it really is the Sun JRE, I would expect this to work.
<j2se version="1.5.0_15" href="KanaJreInstaller.asp"/>And as an aside. If this installer is giving you trouble and the app. requires the 1.5.0_15 JRE, why not simply the default Sun JRE installer? What advantages do you think this installer offers?

JRE version with Forms 10.1.2.3

I just finished installing the patch set 3 for Forms Services 10.1.2.0.2 to update to version 10.1.2.3. The purpose was for our users with Windows 7 IE 8 to be able to continue to use Forms.
I understand that this requires JRE 1.6.0_20. However, most machines still have 1.4.2_XX. I am able to use the updated version on my machine that is XP and IE 7 w/ the 1.4.2 JRE version. One of our users with IE 8 gets this message in the Java Console:
Java Plug-in 1.6.0_20
Using JRE version 1.4.2_12-b03 Java HotSpot(TM) Client VM
He has the new one installed but it forces use of the old one.
Does anyone have a suggestion in configuration with working around this issue for users that will use either version of JRE w/ this Forms update?
I think an answer would be to uninstall JRE 1.4.2 for users w/ IE 8 but we don't have admin control on our machines.
Not a critical issue but your advice/help is appreciated.

Phil,
When you upgraded, did you modify the formsweb.cfg to change the JRE requirement? If you didn't that would explain the message your user is getting:
Java Plug-in 1.6.0_20Using JRE version 1.4.2_12-b03 Java HotSpot(TM) Client VM>
As Chidu suggested, change the following lines in the Formsweb.cfg on the app server:
jpi_codebase=http://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/VerifyItem-Start/jre-6u22-windows-i586.exe?BundledLineItemUUID=D.uJ_hCujxcAAAErFOQkgqsv&OrderID=pYCJ_hCuGowAAAErCeQkgqsv&ProductID=mCuJ_hCyot8AAAEri7RGXQzG&FileName=/jre-6u22-windows-i586.exe

J2SE/JRE Version(s) on Clients

Hi All!
Can someone offer some guidance on what version(s) of J2SE/JRE we should have installed on our clients (PCs)? We have standardized on 1.4.2_13 and are moving to 1.4.2_15 for Vista support, but we've run into several situations where SAP is asking for us to also install 1.5 or 1.6, and we also have other vendors asking for various versons of J2SE/JRE. In the past we tried to use the same version as the version on the server, but we're finding this is hard to do.
Also, if you're running multiple versions, how do you manage cases where 2 browser apps want to use different versions since (at least with IE) it appears only one can be the default.
Thanks!
Jeff

Jeff,
Unfortunately, as you have realised, you're stuffed when it comes to IE and Java. Only one can be used.
We have to produce a certified list of apps that can be run against a common JRE. It looks like a neat matrix sheet and normally works around the lowest common denominator of JRE.
Unless SAP don't support you on older JRE versions, don't be bullied by them into upgrading.
Unless there is a very compelling reason (e.g. you need a patch that requires an upgrade) then I wouldn't change it, for simplicities sake.
I found this link to be of use though:

All jre versions now available for autodl.

A new jre autodownload servlet has now been put in production by Sun that can serve to java web start (and also the new OOPP plugin in 6u10) any veresion of the jre (from 1.4.2 on)
/Andy

When we use the following syntax in the JNLP file, an exception message of "Unable to launch 1.6...installer" is displayed.
{color:#339966}<j2se version="1.6+" initial-heap-size="64m" max-heap-size="128m"/>
{color}{color:#000000}Not too long ago, Java Web Start successfully retrieved the most recent 1.6 installer if the JRE version on the target system was under 1.6.
What has changed?{color}

Most commonly used format

Hello Everyone,
I have just made a promo reel for my girlfriend and I need some advice as to which format to export it in.
I need to do two things; firstly I want to save it as a file we can give to people on a memory stick or via my idisk. I am not an expert with file formats and this is going to be viewed by people with macs and PC's. Is there a format that is recognised more than all the others? I know the quicktime option is probably the best but then within quicktime there are many other options which I am not sure about.
Secondly (and im being a little lazy here because I haven't begun to learn DVD studio pro), if im planning on burning this to DVD, which format will DVD studio pro want to work with? (the footage is NTSC)
Thanks very much for any help.
Double_ohh

It must just be the film industry then. I deal with all sorts of codecs on a daily basis and every time anyone comes across a .wmv file in our company they complain (and we're mainly on PCs except for us in editorial).
We have done extensive research into which codecs are most common, easiest for a machine to run, maintains consistent color across platforms, and doesn't require additional downloads. We deal with everyone from super tech savvy people (we're in visual effects) to producers and directors that only check their e-mail and surf the web.
MotionJpegA and/or PhotoJpeg have zero color loss when compared to the original files. The codec has been around for quite a while so it will play even in older versions of Quicktime. The main drawback is that the file size can get quite large.
My girlfriend is in market research and consulting and she says they use .wmv files all the time. She also said they have had a few cases when they've sent the files to a client on a Mac only to have the client become frustrated because they had a hard time playing them back.
Codecs are a messy thing and certain codecs work best for certain situations. We have had more success with H.264 than Windows Media files but that is just our experience. If you plan on sending it mainly to PC users in a professional office environment then Windows Media will probably work great, if you plan to send it out to a professional creative environment on mixed platforms I would look at using something else.

I have been getting java.lang.ClassNotFoundException: ZeroApplet.class and java.lang.ClassNotFoundException: JavaToJS.class crashes with JRE version 1.6.0_26-b03-384-10M3425 VM executing a Java Applet. Is Apple aware of this problem? No longer supported?

My web page uses a Java Applet to allow my visitors to replay chess games; the Chess Viewer Deluxe applet was written by Nikolai Pilafov some time ago and has been working properly for some time (until recently). I don't monitor this part of my site regularly so I am not sure when it began to fail. On his web site [http://chesstuff.blogspot.com/2008/11/chess-viewer-deluxe.html] he has a link to check LiveConnect object functionality (which fails for OBJECT tags). His recommendation is to "seek platform specific support which might be available from the JRE developers for your platform".
I have been getting java.lang.ClassNotFoundException: ZeroApplet.class and java.lang.ClassNotFoundException: JavaToJS.class crashes with JRE version 1.6.0_26-b03-384-10M3425 VM executing a Java Applet. Until I checked the LiveConnect object functionality, I was unable to identify the source of the console error messages. This does seem to be the smoking gun.
Is Apple aware of this problem? Are these classes no longer supported? Has anyone else had this problem? You can attempt to recreate the problem locally by going to my web page: http://donsmallidge.com/DonSmallidgeChess.html

How to find out jre version installed ,using a java program?

Hello,
Is there any way to find out the installed JRE version using a java program ?
The requirement is as follows:
There is a html page with 4 steps to install a software. each step is a link, which upon clicking does its work.
the first step is to install jre 1.4.2_11 if its not installed in the system. But how can i find out whether jre 1.4.2_11 is installed or not ?
Thanks in advance

In your experience what are the most common errors in binding files when deploying?

As the title suggest I'm interested in discussing the most common errors in binding files when deploying.
Reason for this is that I'm currently working on a Powershell script that can parse a binding file and create a reader friendly report (rtf format) with various information.
But the main purpose for this script is to find common errors in the binding file used. And so far these are the ones I've thought of:
- Tracking enabled for either services or the pipelines they are using (if it's a binding meant for Prod).
- Orchestrations logical ports not having any ports bound to them.
- URI containing certain words that's not ok. For example if a binding meant for Prod contains the word "test" anywhere in the URI then that should be reported in the created rtf report. This also applies vice versa.
So now I need your help with coming up with more ideas on common errors that need to be looked after and reported on if found!
Additional features the report should contain:
- Listing the details of each orchestration, send port, receive port along with their associated receive location(s). To better understand and get a quick overview on exactly what settings are planned to be deployed. Especially the "TransportTypeData"
section which otherwise can be quite tedious to read.
- List each unique host instance, so that I can easier see directly which ones might need a restart after an import.
I'd appreciate if you can come up with any more features that should be included in this script.
/Christian @ IntegrationAdmin.com

Filter on send port not on the same line as the Filter tag.
This one is a nice one, I ran into it several times. Mostly after copy/paste of a port definition for a binding file, because Visual Studio is formatting after paste the XML in a way the filter will get invalid. This leads to a cryptic error
during importing the binding.

No jre version found in launch file

I'm using jdk1.5.0_03 (with all other versions of java removed from my system) and trying to run our web start app that specifies a version of 1.4.2*. After clicking the link to the jnlp file, web start contacts sun to retrieve 1.4.2*, then gives the dialog: "unable to launch FlowJo" (our app). On the details tab, it reports: "No JRE version found in launch file for this system".
When I launch the web start manager, under the user applications tab, I see 3 applications: our app, our installer, and Sun's j2re1.4.2_07 installer. It seems like Sun's installer is being downloaded but never executed.
Am I doing something wrong in my jnlp files? Both our app jnlp and our installer jnlp specify a j2se version of 1.4.2*. Below are the files and exception as reported from the web start dialog. I'm trying to set our app up for internal testing with web start, so I'm using a local ip. Our application uses a custom installer which has its own jnlp file (shown below in "launch file").
Any help is much appreciated,
Peter

Using tag OBJECT on a machine with multiple jre versions

Dear friends,
i guess that this question has been already answered, but i can't find the thread with all infos i need.
So please excuse me if i'm redundant.
This is my problem:
i have a web application that runs an applet, embedded in an html page;
by now the applet is loaded with the standard tag <APPLET>.
I found many Sun's official pages talking about the use of OBJECT tag to specify the jre version that is supposed to run the applet.
I tried many ways but i can't reach the way to avoid loading the applet with the latest jre installed on my pc.
Here is the code of my OBJECT:
<OBJECT NAME="client" CLASSID="clsid:CAFEEFAC-0014-0002-0009-ABCDEFFEDCBB" HEIGHT="38" WIDTH="335" >
                    <PARAM NAME="NAME" VALUE="client">
                    <PARAM name="type" value="application/x-java-applet;jpi-version=1.4.2_09">
                         <PARAM NAME="CODE" VALUE="it.fabio.client">
                         <PARAM NAME="CODEBASE" VALUE="/myapp">
                         <PARAM NAME="ARCHIVE" VALUE="mylib.jar">
               </OBJECT>The machines where the application is deployed have the 1.4.2_09 and the 1.5.0_03 jre versions, but my applet runs only on 1.4.2_09 version.
So i have to find a way to tell the browser which jre has to be called.
Thanks in advance for help.
Regards

Wait a second...there is more to that error message that I overlooked before.
There might be something other than just the way I set the CODE and CODEBASE parameters wrong here
Any ideas?

ITunes is a blank-slate...How do I load the most recent previous version of my library?

I "re-arranged" my files on my computer to free up space and now my iTunes is completely blank. No apps, no music, no ringtones. Nothing. How do I find and load the most recent previous version of iTunes? Since we went to the cloud I haven't actually plugged my phone in to sync it...I'm afraid it will ask me if I want to load what's on my phone into iTunes, and I just want my old iTunes back. Any ideas? TIA!

When you re-arranged your Files for iTunes, in your C:\Users\Your Username\Music\iTunes folder ->should be a iTunes library.xml, and a Itunes library.lib- if you moved those thats why your library is blank.
Simply go to File- Add folder to library-> locate your Music folder- click choose - and you library should come back

Most common JRE version today?
