SUN JVM CodePage

Hi there
When executing an console application, the portuguese characters does not appears correctly. Is there any way to configure JVM code page or anything like that ?
Thanks .
PS: using windows xp

By console application, I assume you mean an application that displays output on the DOS command prompt on Windows?
If that is the case, then you are seeing a well-known problem - the fact that the JVM codepage is the Windows codepage (for Portuguese it would be 1252), while the DOS command prompt uses codepage 850.
The only way to "fix" that (that I have found) would be to perform a codepage conversion on your own when the application runs as a console application. If that is the only way it executes, you are in luck, since you can just always perform the conversion. You can get the console.encoding value using System.getProperties().

BEA-280101 warning while using Weblogic 10.3.3 on SPARC 64bit sun jvm

Hi all:
I got this warning when start Weblogic 10.3.3 on SPARC 64bit sun jvm

I have checked that Native I/O is enabled,but it seems JMS can't find correct .so file
Any idea? Thanks in advance!

We are also getting the same error on a Linux 10.3.3 installation with 64bit jrockit

Is that the correct driver? This is a default weblogic installation, what is missing so it uses the correct I/O method?

MSJVM to Sun JVM for Internet Explorer

Hi,
Currently I am using an applet in a jsp.
This applet is for authentication purpose.
Now currently we want to test it with
sun JVM instead of MSJVM. Could you
please tell what needs to be done.
thanks
radki_j

Just install the Sun JRE version you need and register it to handle the Applet tag which is an option in the Tools->InternetOptions section of IE.

Create Shopping Page gives Javascript Error - Sun JVM in a DMZ?

Hi SDN
We are running on SRM 5.0, with server at 5.5 and we have just implemented SP 11. Since then, our users running IE with the Sun JVM 1.4.2_10 are getting a JavaScript error everytime an applet loads on their page (in this case, it is the applet within the Document & Attachments section). Moreover, our portal is being hosted on an SSL secured server within our DMZ, in conjunction with a Provencia IDS System, Blue Coat hardarware, RadWare, ...etc.
The only way we can make that page work, is by disabling the Sun JVM and use the MS Version of the JVM. At that point, no issue with the applet on our SSL Secured Portal. Even funnier, is that when I'm calling directly the Portal Server (without the SSL proxy), even if i run the Sun JVM, I'm not getting the error. Since we have over 1000 users, it woulde be aimpossible to have all of them making that change... We need to make that work.
Have you ever experienced something like that? If yes, what have you done to fix it? Any suggestion, OSS notes
Thanks in advance
Eric L.

I am having almost the same issue. This is what my java console throws "load: class com.sapportals.portal.epcf.EPCMfactory not found."

IE doesn't recognise Sun JVM..

I stuffed up my IE 6.0 installation .... I can't recall what I changed but the browser doesn't recognise my JVM anymore. Applets won't download...... I did all the obvious as explained on the relevant Sun and MS websites, such as:
- reinstalled JVM 1.4.x
- configured browser using via Java, Internet Control Panels (uncheck the MS JVM, etc.)
- flushed temp internet files
- rebooted
I am getting desperate for any help..... Thanks in advance.

Hello All,
I've been looking into this problem for quite a while now and I'm not sure if it is only 1 problem or two.
On some machines Java appears to be disabled. This is fixable by uninstalling and re-installing either the Sun JVM (as robby_h mentions) or by re-installing the MS JVM (which is a little hard to find).
The second problem I have seen is where the Sun JVM still starts as does the Applet, but the database connection we use doesn't work. It appears to be substituting 127.0.0.1 (the local machine) for the Host in the connection string. I'm not sure if this is the only effect but it does cause a major problem for us as some of our clients are unable to use our e-commerce sites and a lot will not be reporting the issue to us.
I have been working on finding a way to solve the problem. It's not pretty but removing Java (both MS JVM and Sun JVM) completely and then re-installing it has worked so far. I've tested it on win 2k and XP home machines.
I am not sure where the problem actually is. I believe that it's something to do with IE which is changed (probably a/some dll files) when Java is installed. This would explain why in some cases installing a different version of the Sun JVM might work as if the dll files are different then they will overwrite the bad dlls and hence solve the problem.
robby_h, have you tried re-installing the latest Sun JVM since you got it working with 1.3?
If it is a problem with a corrupt dll then I have no idea which one it is. Anyone know how to find out?
Alastair.

Issues with migrating to SUN JVM

Hi
Chapter 4 of the "Microsoft Java Virtual Machine Transition Guide for IT Professionals" [part of the documentation for "The Diagnostic Tool for the Microsoft Virtual Machine"] contains[under a discussion of disabling Java] :
(a) '... the Sun JRE, which "impersonates" the Microsoft Java Virtual Machine in IE ...';
(b) 'Some Java plug-ins install in a Windows system by "impersonating" the Microsoft Java Virtual Machine using the same registry entry and Class ID in installation ... Be cautious when installing JREs that impersonate the Microsoft Java Virtual Machine ...'.
Can anyone provide more information about this "impersonation" and what to be "cautious" about?
In particular:
(1) Does the impersonation only affect interpretation of applets under Internet Explorer plus any direct HTML references to the associated registry entries [and not any direct executable references to the Microsoft Java VM]?
(2) Does the Microsoft Java VM have to be retained [even if another JRE is installed] to support any direct executable references to it?
When I run "The Diagnostic Tool for the Microsoft Virtual Machine" on a Windows 98SE system, its VM Dependency Report has many entries for Micrsoft library modules - eg IEDETECT.DLL - and its Visual J++ Class Report has many entries - eg C:\WINDOWS\SYSTEM\MSHTML.DLL.
There is no information about whether such dependencies are critical - the modules may have alternative paths if the MSJVM is not installed.
At this stage, I suspect that Microsoft is not going to issue updates to such modules [Windows 98 is no longer fully supported] and therefore it would be unsafe to remove the Microsoft Java VM.
Chapter 4 also mentions a "TreatAs" subkey, and recommends removing it. Does the Sun JRE install or rely on such a subkey?
Chapter 6 says that "The use of Microsoft extensions is easy to find in current J++ source files ..." but is there any way that users without access to such source files can find which executable modules are dependendent on the entries shown when I run "The Diagnostic Tool for the Microsoft Virtual Machine" and look at its Visual J++ JAVAREG Report [which lists CLSIDs and associated Java classes for msjava.dll].

HI Owen,
JVM dependent web Applications are not working with IE after migrating to SUN JVM from MSJVM
steps I followed are as follows.
1)uninstalled MSJVM using MSJVM removal tool
2) Install SUNJVM 1.4.2_07
os used is windows xp sp2.
I did checked SUN JVM in Internet options.
Then I tried to test JVM dependent web apps on this they are not working. sometime JVM was attempting to upgrade to a newer version.
But strangely it started working when I followed follwong steps.
1) Install SUNJVM 1.4.1 (initial) - this version actually works proper with Documentum
2) Uninstall SUNJVM 1.4.1 from Add/Remove Programs AND Remove the two Java Folders from Registry, under the Software Folder
3) Reboot the pc
4) Install SUNJVM 1.4.2_07
5)checked SUN JVM in Internet options.
Can Some one help me to know the reason for both not wokring and working.espl working since deepending on this I need to decide on how to migrate to SUN JVM
Thanks
Nagaraj
History:
My client is having MSJVM on their PCs I had suggested to migrate all these MSJVM dependent apps to SUN JVM. In this process I wanted to test these MSJVM apps with SUN JVM. while setting test lab I observed above mentioned behaviour.

It works fine on my computer with the sun jvm, but it doesn't seem te work if you have the microsoft vm installed. I still want to make the applet compatibel for other people. What can I do about this?

There is a way to enable the IE Java console - try googling for instructions. There's a good chance the console displays an error message. Or if it doesn't, add debugging println's to pinpoint where something goes wrong.
The MS JVM is old and has bugs, including security bugs. If the users of your applet are in any way important to you (such as paying customers), try to get them to dump the MS JVM. They are opening themselves up to worms and such nastiness.
By the way, ' if (line != "")' isn't right, you need 'if (!line.equals(""))'.

9i FORMS and SUN JVM 1.4.2_03

Hi,
We are planing to upgrade our IE browser with SUN JVM 1.4.2_03 virtual maching and our forms are not working when we access it from the update browser.
They are working fine with the IE browser and Microsoft JVM.
We are getting FRM -92050 error when we want to use SUN JVM and the same forms working fine with Microsoft JVM.
It is been causing business issues so any early help will be much appriciated.
Advanced Thanks,
Santosh

Hi,
actually I don't know what exact does cause the problems, but the last version of Java 1.4 Plugin I got to work is 1.4.1_02.
If you look at the Java panel of the Plugin you should find a couple of file not found messages spilled out.
Not sure if Java Plugin 1.4.2 already has been certified with Forms. I think that not.

Forms 10g rel 1( 9.0.4 ) vs SUN JVM 1.5

Hello:
From SUN site you can read :
"Changes in 1.5.0_06
The full internal version number for this update release is 1.5.0_06-b05 (where "b" means "build"). The external version number is 5.0u6.
Security Enhancements
Prior to this update, an applet or application could specify the version of the JRE on which it would run. This has changed. All applets are executed with the latest JRE version. Unsigned Java Web Start applications that specify a version other than the latest trigger a warning, requiring explicit user permission before the application will run. Signed Java Web start applications are not affected. "
Assuming that our customer will use SUN JVM , NOT Oracle JInitiator.
We have seen that if in a client machine it is installed SUN JVM 1.4.2_10 ( certified ) AND SUN JVM 1.5 or newer.
there is NO WAY to force Forms 9.0.4 applications to run with SUN JVM 1.4.2_10.
In spite of doing the following settings at formsweb.cfg
# Parameter related to the version of the Java Plugin
jpi_mimetype=application/x-java-applet;jpi-version=1.4.2_10
when you run forms 9.0.4 applications from a browser in that machine, SUN JVM 1.5 is mandatory used by the browser.
It seems that IT IS IMPOSSIBLE to tell 9.0.4 to use SUN JVM 1.4.2_10 because SUN prevents it according to the above documentation .
Q1) I thank your comments on this
Then, when you look for certification info:
a) you can get this info for Forms 10g R2
http://www.oracle.com/technology/products/forms/htdocs/10gR2/clientsod_forms10gR2.html
b) you can get this info for Forms 10g R1
http://www.oracle.com/technology/products/forms/htdocs/10g/clientsod_forms10g.ht
ml
Q2) What are ORACLE plans about certification of SUN JVM 1.5 AND Forms 10g Rel 1 ( 9.0.4 ) ?
Thanks in advance,
Fernando Rey

Hi Guys,
I am currently testing our portal with a number of JRE version or Jinitiator and the SUN JRE.
I found some very useful information about changing the registry of the local PC to re-enable specific versioning, see info, below.
I have tested this and it does work, but you need to be careful with Sun JRE versions to ensure that you are on 1.5.0.7 or higher.
Another useful link is this discussion over on the sun forums.
http://forum.java.sun.com/thread.jspa?threadID=730855
Good Luck
Scott
We have found a conflict with the Sun JRE 1.4.2.6 and version Sun JRE 1.5.0.6
To get around this conflict a registry key has to be added onto the users PC and the user needs to remove 1.5.0.6 and install 1.5.0.7 or higher. To make matters worse the auto-update feature in version 1.4, if left enabled, will update the user to 1.5.0.6 even thought the latest release from the sun web site is 1.5.0.8 !
Therefore can you add this registry key onto the automated install of the Sun 1.4.2.6 setup as per the instructions below.
Troubleshooting Conflicting JPI Versions on the Desktop:
Per oracle note 368775.1, JRE 1.5 will not allow static versions. In other words version 1.5
may override your required version of 1.4.2. They call it a security feature, but it can reek
havoc with oracle forms. This section addresses a possible workaround.
If your users either need to run JPI 1.5 for any reason, here is the workaround to force
BANNER to use ONLY version 1.4.2.
If you launch forms and in the java console it shows version 1.5.X, perform the following
steps.
1. Make a backup of the windows registry
2. Edit the registry
3. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\
4. Create a new directory by highlighting the key above and pressing <RIGHT
CLICK>/<NEW KEY>
5. Rename the key to [Java Deployment]
6. Highlight the new key created in step 5 and press <RIGHT CLICK>/<NEW KEY>
7. Rename this new value to [Policy]
8. Highlight the new key created in step 7 and press <RIGHT CLICK>/<NEW DWORD>
9. Rename this DWORD to “EnableSecureStaticVersioning”
Re-launch forms and verify via the java console that the desktop is returning 1.4.2.

Microsoft JVM vs Sun JVM

We have an application that requires only Microsoft Java VM be running in our IE browsers, so we cannot run Sun Java VM at the same time. Is there a workaround that will allow users to view Discoverer output? I am still investigating utilizing Discoverer as we have an enterprise license, so my choice of client viewers is still undecided.

Because of Microsoft's strong commitment to the Java platform, we have had to discontinue support and certification for the Microsoft VM. The only two JVMs supported and tested for Discoverer Plus are JInitiator and the Sun JVM.
Thanks

Dynamic versioning of Sun JVM

Hi,
I have already read the Oracle about Sun JVM dynamic versioning for Oracle Forms but am still confused. I'm migrating Forms 9.0.2 to 10.1.2.0.2 and would like to use Dynamic versioning of Sun JVM with Sun JVM 1.4.2_06 as a minimum version. What should I put for the following parameters?
jpi_classid
jpi_download_page
jpi_codebase
jpi_mimetype
Thanks.

THE SUN JVM IS NOT INSTALLED

when i open a page with java on it, it is not viewable. instead, i get this error message: THE SUN JVM IS NOT INSTALLED: CLICK TO INSTALL
so i click to install, but download is 108MB. i was told by a friend that all i need is a 14MB download, but dont know how to find it.
another friend told me that i need J2SDK, but that's a 165MB download. then i emailed Sun, and they said i just need JAVA VIRTUAL MACHINE and not J2SDK, but when downloading JAVA VIRTUAL MACHINE, i get JAVA RUNTIME ENVIRONMENT SE v 1.4.2_06 with 108MB.
other things i tried downloading:
-J2SE SDK which is supposed to be 14MB and i keep getting JAVA2RUNTIME ENVIRONMENT SE v1.4.2_06 which is 108mb.
j2re-1_4_2_xx-windows-i586-p-iftw.exe.
-J2SDK SE v 1.4.2_06 by clicking:
For Windows, choose "Windows Online Installation" for the quickest download and installation on a machine connected to the Internet. The default download size is 48.6MB, which is the maximum download. The size may decrease if features are deselected, to a minimum of 14.3MB.'
but what downloaded was not 14MB, it was 165MB.
I need java only for viewing certain parts of pages, nothing more, so 165MB seems crazy. i try to install only certain parts by checking 'do not install this now', but it gets installed anyway. there seems to be no way to only install a portion of the download. and the strangest thing is that i once had java, so where did it disappear to?
how can i just get the 14 mb download. i've tried EVERYTHING.
can anyone help? i've spent HOURS being challenged by this.

you just solved the problem, caffeine! you're the man (or gal) !!!!!
i clicked on: Online Installer and downloaded: http://jdl.sun.com/webapps/download/AutoDL?BundleId=9811
which is now (in properties on the install icon), noted as j2re-1_4_2_06-windows-i586-p-iftw 1.35 MB.
FYI: add/remove programs still says 108MB.
i'm still having a bit of trouble understanding this concept (could be my ADD) so to clarify...you saying that Add Remove Programs contains only an estimate of the size of an install program after installation, not the download size. i just assumed they were the same size. An install program is usually compressed. During installation, files inside the install program are uncompressed and copied to the appropriate locations on your hard drive , meaning that even tho i am downloading something of 1.35MB, those 1.35MB are compressed, and so when i uncompress them (by installing them on machine) the file size is increased? how can 1.35MB increase to approx. 108MB? and in the end, is this taking up 1.35MB or 108MB on my hard drive. (you say 108 is an estimate. but 1.35 is so different than 108, what kind of estimate is that?)
and finally,
- why do some friends have this noted as 14MB in THEIR add/remove programs.
- why do i have 1.35 and not 14MB (which is what most people have).
Most of the files for the JRE are copied to C:\Program Files\Java\j2re1.4.2_06. If you want to see the size of that folder and its contents right click on the folder (j2re1.4.2_06) and select properties. when i go to the actual folder, it says 33.7 MB. now i'm doubly confused as i thought it was 1.35MB.
By the way I believe you have downloaded and installed the JRE 1.4.2_06. yes i have, but i dont think i need the whole Java Runtime Environment just to view apps, do i? whenever i click on a download (like yours, for instance) the link leads to download of JRE 1.4.2_06. how can i get rid of what's not needed. again, i only need JAVA TO VIEW JAVA APPS.
are you exhausted yet??? (sorry, i really am trying to understand this).
thanks soooooooooo much caffeine!

Stack overflow error with Sun JVM

We have an application that was running on MSJVM. Recently we migrated to SUN JVM. After the migration, we get the error message - "Stack overflow at line 0 " at random, while loading applets.
Any solutions to this problem will be greatly appreciated.
Thanks
Nabeel

Where do you see the error message (Java console, ...?)
Googling for "stack overflow at line 0" hints that the problem may be related to JavaScript. Is there JS on the web pages that elicit the error? The JVM upgrade might be a coincidence.
