Stable\Right JDK version for today Applet!

Dear All,
I have some ideas would like to consult you about :
I'm building a heavy-applet (for big customer) which uses swing, high-qualitiy image and audio processing and many see & hear technologies.
Last time we discuss with customer that we will run that applet with JDK 1.4 and later only, after 1 or 2 years running the applet we found out that
90% of bugs come from 10% users who still using old JDK1.4.xx and JDK1.4.1_xx.
So should I discuss again with custome that we just support the applet running with JDK1.4.2 and later only.
I guess 5% of users will not happy for that
(many reasons : don't want to upgrade to latest JDK, company constraint...),
- About the plaform (multi-plaform is supported)
- About the browser (we support all browsers which could allows java plug-in)
Could you please tell me some good reasons that we should use JDK1.4.2 or later for such applet
or still support for JDK1.4 and later because ...(your idea)?
I just would like to find out more information for this case of business.
Thanks,

Well, I've to support Java-1.1 and up which is REALLY painful - since 1.1 browsers are typically so buggy that you cannot rely on what the API provides.
After some time you get a feeling what could work and what does not and you to do your best.
To benefit from newer APIs introcduced in later versions of java we use reflection, e.g. our applet switches dynamically to VolatileImage-Backbuffer if running on 1.4+, we also have 3 implementations for doing http-connections 1.1, 1.2, J2ME and use our self-written selrialization framework which does not rely on reflection.
Painful but we get great compatibility.

What's the right JDK version for windows vista SP1

Hello guys,
I’m trying to install SQL Developer on my old Windows Vista SP1 but as soon as I run it I got a message: Cannot find a J2SE SDK installed at path C:\Program Files\Java\jre6
I was reading a post and this problem could be solved by installing the JDK. I went to the Java Archive Download website (http://www.oracle.com/technetwork/java/javasebusiness`/downloads/java-archive-downloads-javase6-419409.html) and I downloaded 3 versions but none of them are working. There’re tons of them and I really don’t know which one should be the one to be installed in order to get the SQL Developer working. Any chance someone can help me solve this issue?
These are the errors I got when I run the installers:
Jdk-6u26-windows-i586 – error: D: \Java JDK\jdk-6u26-windows-i586.exe is not a valid Win 32 application. Size of the file downloaded: 7140KB
Jdk-6u26-windows-x64 – error: The version of this file is not compatible with the version of Windows you’re running. Check your computer’s system information to see whether you need an x86 (32-bit) or x64(64-bit) version of the program, and then contact the software publisher. (I was quite careless downloading this version cause I know my computer is 32-bit or x86) size of the file downloaded: 69,043KB
Jdk-6u37-windows-i586 – error: D: \Java JDK\jdk-6u37-windows-i586.exe is not a valid Win 32 application sizeof the file downloaded: 67,756KB
Thanks loads

This one should do it.

I suspect an issue with your download if you are getting the invalid application message

Downloading the right iBooks version for iPad 1: solution!!!

Hi,
I needed the right iBooks version for my iPad 1. What I did was: I used my iPad 1 to go to the app store. Once there I looked up 'iBooks'. When I tapped on it to download it it asked me if I wanted to install an older version. I tapped OK and it installed the older version compatible with my iPad.
Done!!!!

No, this won't work. For how to do it see Re: can you download a previous version of ibooks??

Setting different JDK versions for Different webapp in Tomcat

Hi All,
I have 2 web-applications in Tomcat 5. Now for Java I have j2sdk1.4.2 & j2sdk1.3..
Now One of my application needs j2sdk1.4.2 while other can run only with
j2sdk1.3.. (This is an old project & there are java class package norms - like every class should be in a package to import it now. But earlier it was not strict).
Means this is absoulte for me to run one application with version 1.3 while other with 1.4.
But I can set Java_Home env. varibale only once. How can I tell my each web-application to take thier own jdk version in compiling & running.
Is this allowed in J2EE/Web-Containers.
Please suggest if there is any such setting which makes it possible.
THanks you all in advance...
Manoj :confused:

wouldn't matter if you could.
The package enforcement is NOT something from J2SDK 1.4 but from the version of Tomcat used.
Each Tomcat instance will use the same JVM for all webapps running inside it. You'll need a separate Tomcat instance of an older version for the older webapp (or better yet change it around to the new rules).

Pack200 and versioning for classic applets

Is it possible to use the pack200 format and jar versioning with classic applets? I would imagine the answers are resp. yes and no but the docs don't say AFAICT and experimenting is very very time-consuming.
Thanks in advance

Java version for signed applets

Hello,
I was told I must use jdk 1.3 or 1.4 to sign an applet. We want to use 1.1.8 so that it is not necessary for the client to download a plug-in.
I have 2 questions.
1) Is it possible for me to install 1.4 on my machine locally, generate the CSR and keys, then use those to sign an applet running under and compiled using 1.1.8?
2) If we do upgrade to 1.3 or 1.4 but still compile our applets under 1.1.8, is it possible to sign the applet in this situation?
Thanks so much for your help!

Or is there a way to generate a CSR using javakey
instead of keytool since javakey is supported by
1.1.8?I'm not sure about javakey as I have not worked with it. I once made an applet that was signed for both MSVM and the SunVM.
I used the cabsigner from MS Java SDK to sign the cab and the jarsigner to sign the JAR. :)
Then I specified the archive parameter to the signed jar and the <param name="cabbase" value="signedcab.cab"> in the HTML file.

Which version for Swing applet

If you wrote the applet yourself, you should make sure that the plugin has at a minimum the same version number as the JDK that you used to compile the applet.

JAVA_HOME=C:\bea103\jdk1.6.0_17
See if this helps.

JAVA version for NWDS

Hi ,
I am planning to install NWDS (2004s) on my local machine , I want to know the JAVA version that i can use , Will the NWDS work with JAVA 1.5 ??
Regards,
Tarun.

Hi Tarun,
sure, a JDK 5 compiler defaults to source and target level 1.5 and will thus produce classes that are not compatible with a 1.4 runtime ("Unsupported major minor version 49.0"). What's your motivation for wanting JDK1.5? I'd rather go the other way and use a CE IDE for 04s and then use the lower JDK version for the DC build, at least for the Java compiler.
Regards,
Marc
