Javasoft vs. sunsoft JDKs

Can anybody clue me in on the differences between javasoft and sunsoft JDKs.
According to the platform certification detail, Javasoft is specified for
some platforms, Sunsoft for others.
I am trying to do an install on a SPARC platform w/ Solaris 8, which already
has a Java2 installation. When I do a java -version, I get the following
detail...
java version "1.2.1"
Solaris VM (build Solaris_JDK_1.2.1_04c, native threads, sunwjit)
Is this the Javasoft or Sunsoft JDK??? The platform certification detail
indicates that Sunsoft JDK 1.2.1_04 is required for this platform, and I
think I MAY be in compliance, but I'm not sure.
Any help or insight is appreciated.

I'm not 100% sure, but it use to be javasoft releases are reference
implementations & sunsoft releases are
production implementation.

Yes, you are on certified JDK.

TUNING WLS on E10K

Hello,
does anybody have any general suggestions concerning the tuning of
several wls clustered instances on an E10K.
Are there any upper marks for heap and stack sizing which limits the
scalability of each weblogic instance?
OS : Solaris 2.6
Oracle RDBMS : 8.0.5
java-version : 1.2.2_05
Any help is appreciated.
Thanks in advance

You are better off running many instances of WL each with no more than 512M
(probably 256M) than one big instance of WL with 3Gig.

Install JDK in D:\Apps\1.3.1, but classpath=C:\Program Files\JavaSoft\JRE\

I installed the 1.3.1_01 JDK at D:\Apps\1.3.1, but a second copy of the hotspot jvm is installed at C:\Program Files\JavaSoft\JRE\1.3.1\bin. I can find no way to prevent the JDK install program from doing this (w2K sp2).
I wouldn't care, but many programs keep using the C: version. My PATH variable only points to the D: directory, but if I open a cmd window and type java it runs the C: copy. When I installed JEdit 3.2.2 it starts up saying java.home is C:\Program... and I should add tools.jar to my classpath. Well, tools.jar is in my CLASSPATH. It points to the tools.jar on my D: drive!
Does anyone know what is going on? How can I get all programs to point to the java.exe version that is specified in my environment variables?
Thank you in advance,
Kevin

Under Windows, some programs assume that Java is started by %Windows_Dir%\System32\Java.exe. This version will look in the registry to get the current version of Java. The key it checks:
HKEY_LOCAL_MACHINE\Software\Javasoft\Java Runtime Environment\CurrentVersion
In my case, this key says 1.4, so it goes into the 1.4 registry key and finds this:
JavaHome=C:\Program Files\JavaSoft\JRE\1.4
So that's where it generally comes from.
If you explicitly run the java.exe from a specific Java install directory, it will use that directory as the home though.

Memory problem with jdk/jre 1.1.8

My name is BERGMANN Yannick.
I'm working for IRM in Li?ge and we developped an application (user interface for an industrial measurement system) in Java (JDK/JRE version : 1.1.8).
We have a big memory problem with this application :
- This user interface is running on a WINDOWS NT PC with 128MB.
- This is the command to lanch our application :
C:\Program Files\JavaSoft\JRE\1.1\bin\jrew.exe" -ms32m -mx32m -cp "\Program Files\HMI\HMI.zip;\Velocis\Add_On\Jdbc\raima.jar;\Program Files\Swing-1.1.1\swingall.jar" be.irm.hmi.kernel.HMI -t15 -d"Velocis rdstcp" -newdb -mf1m -mr20
- When our application is running, everything seems to be OK in memory for it. The garbage collector seems to work properly and our application has always at least 5MB free memory (We use the java instruction "Runtime.getRuntime().freeMemory()" to know this).
- But when we look in the "Windows NT task manager" for the "jrew" application, the memory increases ALWAYS.
- After 5 days our application is completely frozen and blocked ...???
- here is a memory map of our Windows NT PC :
     "jre.exe"     "commit total"     "commit limit"     "commit peak"     "physical total"     "physical available"     "physical file cache"

We had a memory problem with a swing applet in our company. The major reason for this was that we added new components in a JTree and removed them later again, and the components we removed were never garbage collected. This was because with these components we added different listeners, and we didn't remove the listeners after we didn't need the components anymore. After we corrected this, the components where garbage collected.
Perhaps it's a similar problem you have, or I have no idea. Check that you remove actionlisteners, mouselisteners etc from components you want to be garbage collected.
You could also test your application with OptimizeIt to see what objects you create and how many you get of them over time: http://www.vmgear.com

'Software\JavaSoft\Java Runtime Environment\CurrentVersion' Error

Hi Friends,
I've JDK1.5 installed and everything was working fine till I installed JBuilder(i guess which uses JDK1.4).And now when i try to compile my programs from command prompt ,i get the following error.Please help.
D:\>java MailExample
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.4', but '1.5' is required.
Error: could not find java.dll
Error: could not find Java 2 Runtime Environment.
[/code

I noticed the JBuilder is using JDK1.4.So JBuilder is written in Java itself.
..while i had
JDK1.5 on my system.So I guess,during installation,it
changed the registry settings to point to
JDK1.4.....can i just set the path..instead of
renaming the folder???I would not expect an IDE to change the system JDK without permission. You can change the path (and any CLASSPATH) settings. However
(1.) Most IDE's would retain their own classpaths so you might need to look for these.
(2.) JBuilder presumeably contains many classes using many API's. Java is not not 100% backwards compatable. It may be worth checking the JBuilder site to see if anyone else has had the same difficulties before you do too much. I am guessing that they have some sort of noticeboard or forums. If not you can always change back later!!!

Relocation of JDK & drastic performance slowdown?

Hi there, and thanks in advance for any suggestions:
We are experimenting with redistributing the JDK (1.4, when released -- working with b2 a/t/m, will upgrade next week) as part of our product within our directory structure. With the Windows version of our product we are experiencing some bizarre, drastic performance slow-downs in XML-related operations (parsing, transformation) when using Tomcat 3.2.3, at least, and possibly other Java-based software, with this "embedded" JDK.
All of Tomcat's pre-requisites (TOMCAT_HOME, JAVA_HOME env vars) are being set correctly, and I've also examined the the JavaSoft and plugin registry keys very carefully and made sure they are getting re-populated correctly on the target (installation) machine, naturally with new paths where needed. Nothing has actully been done to this JDK, mind you, other than the aforementioned relocation.
...Of course, if that wasn't vague enough, we sometimes see irrational slowdowns in apparently random installations when we are using a normally installed JDK/Tomcat combination. We are trying to nail down exactly what yields what, but that's just going to take time. Could this have to do with mis-matches with the XML-related stuff in Tomcat's jaxp.jar and JDK 1.4's new XML stuff?
So, any ideas? Thanks much.

I assume that you have checked to be sure that no exceptions are being written to the application server log file? There are non-fatal exceptions that I have seen that are "masked" to the user but can be seen in the logs that can occur. I do not know if that is possible in your server combination. Just a thought of another place to look.

JDK 1.4.2 and scr-directory

Does anyone know from where I can download the src-directory for JDK 1.4.2 ? I downloaded JDK 1.4.2 from the javasoft.com and got all directorys except that one.

Plug-in stopped working in Internet Explorer after upgrade to JDK 1.4.2

I've been struggling with this one for a week now with no success, hope someone can help. I have Windows 2000, SP4, IE5.5, everything was working fine with the initial installation of JRE 1.3.2, then upgrades to 1.3.4, 1.3.7, 1.4.1 and finally 1.4.2. An applet forced an install of 1.3.1_07, and it stopped working, I uninstalled both 1.3.1_07 and 1.4.2 and reinstalled 1.3.1_07, and since then I get a dialog with the message:
Cannot load class sun/plugin/JavaRunTime.
The Bridge was installed at <C:\PROGRA~1\JavaSoft\JRE\1.37DB1~1.1_0> but the class is not there
Modify the registry key to reflect the new bridge location
The key is HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Plug-in
or change your CLASSPATH to include the new directory
Please consult the documentation for more information
And the dialog title says "Java(TM) Plug-in 1.4 Fatal Error"
BUT 1.4 is uninstalled and totally GONE!
I have uninstalled and reinstalled numerous times, numerous versions of JDK/JRE, always with the same basic result. Any attempts to install 1.4.x (either JRE or JDK) give this dialog PLUS a series of little dialogs with the header "asdas", and the message "register failk". I've looked through the forums and buglists for this same problem and found a few mentions of it, but there never seems to be any solution given.
And by the way, Mozilla 1.4 works perfectly with all the plug-in versions I've installed.
I'm beginning to believe there's a conspiracy....

I found my own solution to this one after many more hours of frustration. I found that there was a toolbar applet installed in Internet Explorer that started its own private JVM, and that JVM was being seen by the plugin code for 1.3.1_07. Apparently there was some conflict between what the plugin code expected and what that private JVM (not sure what version it was, the code had no mention of it) had to offer, which caused the crash dialog. Uninstalling the toolbar (and its parent application) solved the problem. I may do further testing to see if there are any plugin versions that do work with this particular applet.
It is also still a mystery why this problem only cropped up after installing and uninstalling 1.4.x version of the plugin, but I didn't keep close track of the whole sequence so it may have been coincidental.
Hope this helps someone.

JAVA_HOME, JRE and JDK

Does anyone know what JAVA_HOME should be pointing to if only the JRE in installed? What it should be pointing to if the JDK is installed?
On Windows, I notice that c:\program files\JavaSoft gets created after install. For which install does that happen? For the JRE and JDK install? Should JAVA_HOME be pointing to that directory?
I couldn't find any java.sun documentation about the role of the JAVA_HOME env var. If anyone can piont me to some, that would be appreciated. :-)
Version: 1.3.1
Thanks in advance.

Dear dinogg
Does anyone know what JAVA_HOME should be pointing to

actually it is for jre but when u install jdk it also install jre if you notice there is a part setting up java runtime environment
I couldn't find any java.sun documentation about the

not sure where you can find it

However it seems the "default java" part of the JDK installation is broken on that machine given the missing registry key error. A reinstall of the software is probably a safer option.

JDK installs JRE in 'default' folder (only)

The JDK (j2sdk-1_4_2_04-windows-i586-p.exe) installs both the JRE and the JDK.
However, there is an issue if you intend to install the JDK in a folder other than the default, which is: 'c:\program files'. In that case, the JDK installs correctly, but the JRE will still install in 'program files' regardless. This creates potential conflicts with some programs, and the 'Java Home' variable in the registry will be incorrectly reflected as within 'program files'.
If you need to install the JDK in a directory other than the default, you can work around this issue by first dowloading and installing the JRE by itself. Select 'custom' install and indicate the name of the folder where you want the JRE installed. Then download and install the JDK.
If you have already installed the JDK and there is already a 'java' folder under 'c:\program files', first uninstall the JRE using Control Panel's Add/Remove Programs, and then download and reinstall the JRE by itself. Select 'custom' install and indicate the name of the folder where you want the JRE installed.
When the installation is complete, check that there is no 'java' folder under 'c:\program files'.

You seem to under a misunderstanding of the install process defaults.
However, there is an issue if you intend to install
the JDK in a folder other than the default, which is:
'c:\program files'. The default directory for the SDK (Software Development Kit, used to create Java programs) is C:\j2sdk1.4.2_04
In that case, the JDK installs
correctly, but the JRE will still install in 'program
files' regardless.The default for the JRE (A public version of the runtime, used to run Java programs outside of the development environment) is C:\Program Files\Java\j2re1.4.2_04
This creates potential conflicts
with some programs,Not unless one of thes "some programs" has been created in a non-standard manner that I'm not aware of.
and the 'Java Home' variable in
the registry will be incorrectly reflected as within
'program files'.This is done so that Java programs can find the public JRE that they need to run.
If you need to install the JDK in a directory other
than the default, you can work around this issue by
first dowloading and installing the JRE by itself.
Select 'custom' install and indicate the name of the
folder where you want the JRE installed. Then
download and install the JDK.
If you have already installed the JDK and there is
already a 'java' folder under 'c:\program files',
first uninstall the JRE using Control Panel's
Add/Remove Programs, and then download and reinstall
the JRE by itself. Select 'custom' install and
indicate the name of the folder where you want the JRE
installed.
When the installation is complete, check that there is
no 'java' folder under 'c:\program files'.The following is quoted from the Installation Instructions for this version:
"Private vs. public J2RE - Installing the Java 2 SDK installs a private Java 2 Runtime Environment and
optionally a public copy. The private J2RE is required to run the tools included with the Java 2 SDK. It has
no registry settings and is contained entirely in a jre directory (typically at C:\Program Files\j2sdk1.4.2\jre)
whose location is known only to the SDK. On the other hand, the public J2RE can be used by other Java
applications, is contained outside the SDK (typically at C:\Program Files\Java\j2re1.4.2), is registered with
the Windows registry (at HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft), can be removed using
Add/Remove Programs, might or might not be registered with browsers, and might or might not have
java.exe copied to the Windows system directory (making it the default system Java platform or not)."

List of available JDK/JRE

Is it possible to retrieve list of available JDK/JRE in java(swing) application ?

Hi There,
Right, there is no prebuilt method available. But, if you want you can have a look at registry key
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit
HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment
You will get all the required information.
Hope it helps
