Different JRE Versions

Hi ,
We are running our application hosted in 10g Release 2 version 10.1.2.3.
As Only JRE 1.5.0.9 and above is supportable client software we are using 1.5.0.9 for our forms applications. However in one of our client place we have a Java application which uses 1.6 and above releases of JRE. Now we have 2 different versions of JRE installed in a PC. How to make sure only our forms application is using only 1.5.0.9 and not any thing else, because by default it picks up the highest version of JRE software installed in the client PC.
So in essence even if higher versions of JRE is installed in the client PC my forms application should pick up only the version i have mentioned in formsweb.cfg file and not any other version of JRE software installed in client PC.
We are forced to this option because there are some known issues if we run our application apart from JRE 1.5.0.9.
Request the forum users to participate and help me out of this.
Thanks

Hello.
We have a Oracle Forms application which also uses Discoverer Plus and Reports.

Need to run swing GUIs under different JRE versions

I need to run swing GUIs under different JRE versions. Where can I find information about how to use only classes which exist from version 1.1.7 and above?

Under 1.1.7, Swing (then version 1.0) was under com.sun.java.swing. The package name changed in Swing 1.1 b3/JDK 1.2 to javax.swing. You can see what classes were available under Swing 1.0 at http://java.sun.com/products/jfc/swingdoc-api-1.0.3/frame.html

I cant sleep....Running two different JRE versions........

Hey Guys,
I m sure u must be rocking !!! Let me come to the point !! I have following doubts...
1) Is it possible to run different JRE versions on the same machine...? This might be a real life scenario. For example u have java application-1 installed on ur machine which uses JRE1.4. Then u install another java application-2 which was built and tested using JRE1.5. That means u need to have both the JREs on ur machine and User might invoke both the application at the same time which needs respective JREs to be invoked.
If u smart guys guessed it that this guy is coming from .NET back ground and talking about Side by side execution, then u got it right. I m planning to shift the parties !!
2) If above answer is yes, then How can we achive it...?
Thank you guys !!

> I could not think of any better scenario on top of
my mind, But even the examples which I gave are
valid i guess, may be some people will agree with me
in the forum....
"I guess" and "maybe" are far different from "it is always better to not touch the old application and its JRE".
> But i dont understand why u think that these
examples are non sense !!
I work for a multi-billion dollar business in which the JRE of a critical application was upgraded without a problem. According to your suggestion, that's a mistake, but I have a hard time imagining what your justification for that position would be.
> Correct me if i m wrong
anywhere....I m very new to Java,
Considering some different scenarios is good for the imagination. Not to be too harsh, but perhaps counselling people that one should never upgrade the JRE of a business- or mission-critical application should wait until you have some actual experience. :o)

Different JRE versions coexisting

Hello everyone;
I need two have two different versions of jre coexisting within the same oracle instance. The platform is Tru64, Oracle 8.0.6 nad the two versions of JRE are JRE 1.1.8 and 1.2.8.
Has anyone tried something like this before?
Any input will be highly appreciated.

Different JRE Version requirements

I apologize in advance if this has been posted and answered already; I couldn't find the right combination of keywords to locate it...
The company I work for has two large partners that it works closely with. One of these partners Java programs require JRE 1.4.2 the other company's programs require at least JRE 1.5. To this point we have not been able to find any way to direct company A's java programs to use JRE 1.4.2 and company B's programs to use JRE 1.5 on the same computer. This has required that certain people be setup for company A and other people be setup for company B. Is it possible to force these programs to use the version of Java they're looking for on the same computer?
In one case these programs are a mix of Java applets and JNLPs, while in the other they are all Java applets.
TIA!

Try it and see, I've ran earlier version bytecode on new releases and also compiled old source on new JDK's without any problems before, but then your app is not my app and you may have used something or combinations of somethings that nobody else ever has and it yacks on you.
Never know until you try it.
BTW: I'm still running some of my 1.5, 1.4, 1.3, and 1.2 code on 1.6 no problems, but then not all of it is rocket science either.

Compile with different JRE Version

Hello!
Exists some problem compile application using JRE 1.5.0_8 and run with JRE 1.5.0_11?
Thanks a lot

Is any difference in decryption using Jsafe in different JRE versions?

Hi,
Result of Decryption using JSAFE will differ, because of difference in JRE?
Thanks,

If JSAFE is a any good then no! Of course, you could have used it wrongly then there might be a problem.

Running different JRE on the same system to measure JRE Performance

Hey there,
I want to run several java benchmarks on different runtime environments on the same system.
Now, I need to know what I have to consider that those machines do not affect each other?
What do I need to consider while installing those different runtime environments.
How do I have to set the classpath, etc. - I guess it shouldn't be set...
Are there any files in the operating system that could affect the different JRE versions, such as java.exe and javaw.exe in the Windows NT System directory? What do I have to do with those files?
And which would be the proper steps to reach a meaningful result?!
Right now I am using Windows NT, but I will also try to run some tests on Linux! So, I am open for any kind of help!
Thanks,
Marc

Hi Marc,
Have you considered installing one JRE at a time and running your benchmarks? Before installing the next JRE, uninstall
the existing JRE. Thus eliminating any possibility of
overwriting/corrupting any of the Windows NT System
directories or registry settings.

Multiple jre versions using same cache location

Hi,
i searched the web but couldnt find an answer.
I have a Terminal Server deployment with various installed jre Versions (1.6x and 1.7x) on the same Server as well as on different Server Silo Setups.
But for all Servers i configured the Cache Location to H:\Java-Cache (Homefolder of the user) in the deployment.properties file.
1. are there any Problems to expect when using the same Cache Folder for many different jre Versions (jre 6/7/8) ? Any knows issues about that ?
2. is it supported to share the same cache Location (for example D:\java-cache) for many users ? i cannot find ony official KB or Oracle Note about this.
There are a few Blog Article out there which describe to configure the Cache Location on a terminal Server to a local location like D:\java-cache shared by
many users. Does it depent on the Java webstart application if tha works well ?
Thanks a lot,
Marcus

Hi Tyler,
In my opinion, you could go ahead with first option - have multiple JRE's and maintain the environment variables accordingly.
This should not be a problem as the envrionment variable would take care of which JRE is used. Also as you have only another ABAP system on the same server, the other older JRE would only be required during the SAPInst operations. Non-existence of a Java system makes things simpler here

J2EE and related J2SE/JRE versions

I understand the difference between J2EE and J2SE/SDK/JDK, and JRE. However, I'm having trouble identifying what version of SDK each of the J2EE versions uses. Maybe they match up.
For example, if I have an old project someone says was built with J2EE 1.3 SDK, does that use J2SE/JRE 1.3? Does Java EE 5 use Java 1.5? 1.6? 1.4? (For example, if I'm setting Eclipse Compiler Compliance Level for a J2EE 1.3 project, what should it be?)

is there a way for me to know what Java version that would have been or could have been compiled against?No.
Edit: Slight clarification - the class files in the application contain a magic number that corresponds with the compiler target - so for any given class file you can determine what JRE was targeted at compile time. This can be different from the compiler version. Different classes in the same application may have been targeted to different JRE versions.
Are there any versions of Java that it could not be compiled against?No.
what version of Java does the Application Server on which this will be deployed support.The Application Server will be running on a JRE corresponding to a particular Java release. That JRE will support all versions of Java prior to the release. Code compiled on subsequent versions of Java can, if suitably written, be targeted to run on that version of the JRE and (depending on versions) may not need specific targeting to do so. Whether they in fact work or not depends entirely on what library calls they make.
What's the business requirement that drives this request?

How can I switch different JRE in one PC

I am sorry to post it in this forum because I post almost the same in JRE forum but I don't get any help there for 2 days.
My problem is that I have two systems to be used in different JRE enviroment.A system can only run in JRE 1.3 and B system can only run in JRE 1.5 enviroment.But I have to run both in one desktop(which use WinXP SP2),how can I do it . I tried some methods like below:
Method 1:
I Edited the registry using the cmd of regedit , edited some like these.But it did not work .
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{08B0E5C0-4FCB-11CF-AAA5-00401C608501}\TreatAs]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{8AD9C840-044E-11D1-B3E9-00805F499D93}]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{8AD9C840-044E-11D1-B3E9-00805F499D93}\InprocServer32]
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\JavaPlugin\CLSID]
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit]CurrentVersion="1.X"
[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment] CurrentVersion="1.X"
Method 2:This method is post in http://java.sun.com/j2se/1.5.0/docs/guide/deployment/deployment-guide/jcp.html#java as belows:
Example:
Assume you are running on Microsoft Windows with Microsoft Internet Explorer, have first installed version 1.4.2, then version 5.0, and you want to run 1.4.2.
Go to the j2re1.4.2\bin directory where JRE 1.4.2 was installed. On a Windows default installation, this would be here: C:\Program Files\Java\j2re1.4.2\bin
Double-click the jpicpl32.exe file located there. It will launch the control panel for 1.4.2.
Select the Browser tab. Microsoft Internet Explorer might still appear to be set (checked). However, when 5.0 was installed, the registration of the 1.4.2 JRE with Internet Explorer was overwritten by the 5.0 JRE.
If Microsoft Internet Explorer is shown as checked, uncheck it and click Apply. You will see a confirmation dialog stating that browser settings have changed.
Check Microsoft Internet Explorer and click Apply. You should see a confirmation dialog.
Restart the browser. It should now use the 1.4.2 JRE for conventional APPLET tags.
I tried this method but it did not work either.
By the way , the method I use to check whether the switch of JRE versions is work correctly is this :
1.Create a html file which contains OBJECT tag
2.Double click the html file and then check the information in the java console in the window's taskbar.
3.What the java console says is the JRE version I am using now
Is this check method right?
I found that many people confronted the same problem like me but they resolved it by the method of changing control panel, so I am doubt about the check method.
Can anybody give me some help?
Thanks a lot in advantage.

Some additional information:
I tried the method of changing control panel by JRE1.3's control panel to change current JRE enviroment to JRE1.3 (see http://java.sun.com/j2se/1.5.0/docs/guide/deployment/deployment-guide/jcp.html#java), and I found that in the IE->Tool->Intenet Option->Detail Setting Panel the JRE version used in IE had been changed to JRE1.3 really.But when I connect System A(which use JRE1.3) use IE,the started java console is still JRE1.5 and some applets can't run in the enviroment.

How to Launch an Integration Builder under two different java versions

How to Launch an Integration Builder under two different java versions     1
1. Situation     2
2. How To Do     2
2.1 jre preparation     2
2.2 Put them into the system     2
2.3 Execute a Java Web Start under jre 1.4.x version     3
2.4 Change Java Runtime Versions     3
2.5 Launch an Integration Builder     6
1. Situation
OS: windows 2000 pro English
Java version: jdk 1.5.x was already installed. (Its not permitted to change.)
I dont have any authorization to install any software on the PC.
But I need to use an Integration Builder.
I already knew URLs of an Integration Builder (http://<hostname>:50000/rep/start/repository.jnlp).
2. How To Do
At this moment, an Integration Builder (XI 3.0) can be launch under jre 1.4.x environment (on windows).
2.1 jre preparation
I download j2re-1_4_2_10-windows-i586-p.exe from http://java.sun.com/j2se/1.4.2/download.html
I installed it on my home PC and copied all files from C:\Program Files\Java\ j2re1.4.2_10\ into my USB.
2.2 Put them into the system
I pasted j2re1.4.2_10 folder from my USB into the windows 2000 pro system.
Finally, I could list up all of javaws.exe under this system.
c:\j2re1.4.2_10\javaws\javaws.exe
c:\Program Files\Java\jdk1.5.0_05\bin\javaws.exe
c:\Program Files\Java\jdk1.5.0_05\jre\bin\javaws.exe
c:\Program Files\Java\jre1.5.0_05\bin\javaws.exe
2.3 Execute a Java Web Start under jre 1.4.x version
I executed c:\j2re1.4.2_10\javaws\javaws.exe .
2.4 Change Java Runtime Versions
Go to File-> Preferences -> Java
As you can see, it indicates 1.5 version.
Click [FIND] button.
Click [NEXT] button.
Click the j2re1.4.2_10 folder.
Click [NEXT] button.
A JRE Finder is able to find javaw.exe automatically. Or you can indicate C:\j2re1.4.2_10\bin\javaw.exe directly.
Click [NEXT] button.
Finally, there are two Java Runtime Versions. Now you need to uncheck the Enabled column of 1.5 version and check 1.4 version.
Click [OK] button.
Well, in the General tab, I selected None for Proxies.
2.5 Launch an Integration Builder
In the Location field, I typed the URL of an Integration Builder jnlp.
http://<hostname>:50000/rep/start/repository.jnlp
SAP Integration Builder comes up inside Applications area.
Select it and click [Start] button.
If you click Environment-> Integration Builder (Configuration), you can launch Integration Builder: Configuration.

I am not getting anywhere with deploying my application or
applet.
I have set up my bc4j project. It contains all my VO info,
links, application module. (proj a)
I then have another project with DbInfo in it(has all my rowset
info), Multiple Frames, and my Applet.java file.
Actually I have an Applet.java file and a Application.java file
because I was seeing if both/either worked. Anyway they seem the
same, except for that extra window that comes up when you run the
applet.
I follow the steps in the oracle directions (from earlier post).
And all seems ok. But at ---->
[*] Select the subdirectory under myhtml where your applet's HTML
file
is located, and enter the directory path of the 'staging'
directory you
created in step 3 above, if different from the default.</li>
[*]Select the HTML files that JDeveloper created to run your
applet.</li>
[*]Select all of the Java source files in your project that make
up the
applet.</li>
I have no HTML file associated with my applet, at least that I
know of.
So do I need to create one, or should it of been done
automatically.
Also, I trying to figure out what will be the best way to deploy
my project. Applet or stand alone application is what my first
choices have been so far. I have read that there is some issues
with applets being served from a different server than the
database. So a stand alone application was my front runner, but
I haven't gotten either way to work yet.

Have you tried double clicking?
If this doesn't solve the issue, you might want to try using a different version of the browser and disable the pop up blocker on your browser.
