[solved] 32bit Sun JVM on 64bit Arch

Hello,
Does anybody know an easy way to install 32bit Sun's JVM on 64bit Archlinux?
I know that I can download installation script from Sun's website but I want to make this JVM available to all users and install it in some clean way --- making somehow Arch package from the Sun's installer would be nice.
Maybe I could use the ABS tree, there is a JRE and JDK there, but I don't know how to compile them to 32bit versions and make x86_64 packages of them.
THX in advance.

Yes - just use my package here. I've used it for quite some time now, and it works perfectly. One small note - it's expected to be the only JDK on your system (no parallel 64-bit version). I did it that way because I haven't had the time to make something like Gentoo's 'java-config' or 'eselect' utilities. However, it does work with everything, even Eclipse.
Good luck!

[SOLVED]Compiling 32bit C programs on a 64bit arch

Hi guys, for the first time I decided to use 64bit arch on my machine and so far no complains (I don't think there will ever be). I'm a student of computer engineering and I use C to code some projects but I haven't found a way to compile 32bit programs on my 64bit arch. Everybody says "just add -m32 flag to the compile step" but I think this is not all I have to do (it doesn't work if I just do that).
To prove it I have created a simple "hello world" in C:
#include <stdio.h>
int main(){
printf("Hello, World");
return 0;
When I try to compile it, I just run
gcc -m32 hello.c -o hello
But all I get is
In file included from /usr/include/features.h:399:0,
from /usr/include/stdio.h:27,
from test.c:1:
/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory
compile finish
Needless to say it doesn't create the hello executable. Is there some packages I have to install in order to have this happen?

Well, you could see that something "-32" is missing so you are searching for 32 bit stuff that is not installed.
There's a tool called pkgfile which searches in the repository database for a file name and tells you which package it is in.
In this case, stubs-32.h

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?

[Solved] 32bits app on 64bits system

Hi,
I get the following message when trying to execute the anubis program :
$ anubis
bash: /usr/bin/anubis: Aucun fichier ou dossier de ce type
(which means No such file or directory)
The file exists so I guess the probem is that anubis is a 32bits prog and my system is arch64.
According to the wiki it is possible to execute a 32bits app on a 64bits system if I install the lib32 libraries.
So which library should I install ?
WIll these solve my problem ?

I have been trying to install 32bit packages on my 64bit Archlinux.But when ever I issue a command eg:Pacman -S lib32-glibc I get an error "Target not found".I have enabled the
[multi-lib] respository.I know that it shouldn't be a problem once you enable the respository.I must be missing out something here.I have searched for lib32 packages with the command "pacman -Qs lib32" but all in vain, there aren't lib32 libraries installed :-(.
Any help will be appreciated.
Thanks

Oracle 10g + Solaris + 32bit Sun Hardware

Does Oracle 10g (which has a default 64bit Solaris installation) work on solaris + 32bit Sun Hardware? thanks

Hi,
yes, it does work on a 32 bit hardware, but you need a 64 bit version of Solaris.

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?

jstack shows the same error with a very similar exception. I have found that other people is having this problem but I have found no fix avalaible on the Internet. ( see, for example, http://www.javalobby.org/java/forums/m91812587.html#91812522 )
 
Other applications like jconsole work perfectly. Any alternative tool may solve the problem,
 
By the way: I am using:
O.S. : Linux Mandriva 2006 
JVM: java version "1.5.0_06" 
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode)
 
Thanks in advance,

guys,
I was fiddling around to test jmap,
here are the things that worked for me.
$ jps

8214 Jps
7045 Main

$ jmap -J-d32 -heap 7045
It seems only the Main pid will work and not all others .......
post your suggestions.

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!

Cannot print with sun jvm

Hi all.
I am having trouble with printing.
Printer icon in browser is red crossed, saying: can't print (no browser privileges)
This is happening with sun java virtual machine, in both iexplorer and mozilla.
(all three of them latest version). Disabling sun jvm and using ie with native
ms jvm works fine.
I'm using Win XP Sp2, firewall enabled, everithing up-to-date.
Sun Java console says:
Secure Global Desktop 4.00.903: Can't print Can't Print (No browser privileges):java.security.AccessControlException: access denied (java.io.FilePermission <<ALL FILES>> execute).
Printing not possible. Please inform an Administrator.
This is happening after upgrading from 3.30.929 -> 3.42.947 -> 4.00.903.
In case it matters, server is RH 9.
Any tip would be appreciated.
TIA
Alan.

Solved.
Some of the files at /opt/tarantella/var/docroot/java
were not publicly readable.
A permissions denied error was appearing in apache's error log.
Changing files from 0640 to 0644 solved the problem.
Another solution could have been adding the group ttaserv to
my apache user, to allow my apache to access all tta webserver
related files. But I won't do it by now unless other problems
arrise.
Hope this could help someone else.

Alan.I am using my own web server, RH's default apache, and installed tta's

When tested against tta's webserver this problem does not occur.
Anything to update in my own apache config? Everything was working fine
in tta 3.30.

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."

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

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.

Sun JVM works, Microsoft VM gives an error

I've got this applet:
import java.awt.*;
import java.applet.Applet;
import java.net.*;
import java.io.*;
public class Standen
extends Applet {
private URL sourceFile;
private BufferedReader inFile;
private String lines="";
public String getScores(String bestand) {
try {
 sourceFile = new URL(getCodeBase(), bestand);
getFile();
 getMostRecent();
catch (Exception ex) {
return "";
return lines;
private void getFile() throws Exception {
URLConnection link = sourceFile.openConnection();
inFile = new BufferedReader(new InputStreamReader(link.getInputStream()));
lines = "";
String line = "";//lezen van bestand
do {
if (line != "") {
 line = line.trim();
lines = lines + line + "\n";
line = inFile.readLine();
while (line != null);
inFile.close();
private void getMostRecent() {
 String term = "<mostrecent>";
 String eindTerm = "</mostrecent>";//Tag met mostrecent
 String vergelijkLines = lines.toLowerCase();//Hoofdletters maakt niet uit
 int plaatsTerm = vergelijkLines.indexOf(term);//plaatsen opzoeken van de tags
 int plaatsEindTerm = lines.indexOf(eindTerm);
 plaatsTerm = plaatsTerm + term.length();//Tag zelf niet meenemen
 if(plaatsTerm!=-1 &&plaatsEindTerm!=-1) {//alleen als de tags voorkomen
 lines = lines.substring(plaatsTerm,plaatsEindTerm);//tekst kopieren
 } else {
 lines="";//anders niks teruggeven
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(""))'.
