JDK/JRE 1.4 ORB and Runtime support

Does anyone using JDK 1.4 CORBA stuff know whether or not one has to run the ORB process in order for a CORBA
client (which is actually a WL 5.1 stateless session EJB) to connect to a CORBA Server running Orbix? Is ORB daemon and use of servertool support for "CORBA servers" or are one (or both) of these required for JDK 1.4 CORBA clients. Need to know before suggesting upgrade to JDK 1.4, since I want to make sure I understanding issues for supporting production deployment.

No you does not. ServerTool is required when you want to made your server persistant. So since your server is connected to an Orbix ORB you do not have to.

JDK + JRE installation from AUR, and OPENJDK6 removal...

Seems to me most of the discussion about this is outdated, so here I go:
I have been running into some issues with programming Arduino. Replaced my avr-gcc with avr-gcc svn, but to no avail. So now I'm going for the standard distribution package of Arduino on most, if not on linux, systems (MACOSX, Windows) that uses JDK and JRE from Sun Oracle. Got the PKGBUILD tarballs from AUR and successfully built my own JRE install, but here is my issue:
[denizen@FIDO-ARCH jre]$ sudo pacman -Rdu openjdk6 && sudo pacman -U jre-7-3-x86_64.pkg.tar.xz
checking dependencies...
warning: removing openjdk6 from target list
there is nothing to do
resolving dependencies...
looking for inter-conflicts...
:: jre and openjdk6 are in conflict (java-runtime). Remove openjdk6? [y/N] y
error: failed to prepare transaction (could not satisfy dependencies)
:: eclipse: requires java-environment
:: netbeans: requires java-environment
So I'm assuming I need JDK as well, but when I build JDK from AUR I get:
[denizen@FIDO-ARCH jdk]$ makepkg PKGBUILD
==> Making package: jdk 7-3 (Fri Sep 30 00:45:39 PHT 2011)
==> Checking runtime dependencies...
==> Missing Dependencies:
-> jre
==> Checking buildtime dependencies...
==> ERROR: Could not resolve all dependencies.
So has anyone done this without issue already? Am I missing a step or command? I'm at a loss at the moment.

Now, can you tell me how to recycle the JDK packaged in the JRE AUR PKGBUILD script fetched from the internet? Its such a bother having to download it again when I already have a viable copy.
Edit: What I mean is reuse the JDK package gotten from Sun Oracle which currently resides in the src dir of my JRE AUR package build. I tried copying it straight to the src folder of the JDK builder, but to no avail... currently looking through makepkg wiki...

Install JDK/JRE 1.4.2 *after* JDK/JRE 1.5

Hello,
I've installed the latest JDK/JRE 1.5, but for various reasons I need to install the latest version of JDK/JRE 1.4.2.
I'm using Windows XP SP2, and the Firefox browser is my default web browser.
Is this possible without creating a mess? In other words, will the 1.4.2 JDK/JRE installer recognize that a later version of the JDK/JRE is already installed and not replace such common components as the Control Panel applet with the earlier version? And will I be able to easily specify what version of the JRE the system should be executed with Java programs, jars and applets, as that Java Control Panel is supposed to allow?
I really want JDK/JRE 1.5 to be the usual system default, but allow occasional temporary changes via the Java Control Panel. I would
change over to the JDK 1.4.2 by altering the JAVA_HOME to point to the appropiate directory and placing %JAVA_HOME%\BIN at the head of the PATH.
Will this work?

I've installed the latest JDK/JRE 1.5, but for
various reasons I need to install the latest version
of JDK/JRE 1.4.2.So do it.
Is this possible without creating a mess?Yes. Though you can of course only use one plug-in and only have one in your path.
In other
words, will the 1.4.2 JDK/JRE installer recognize
that a later version of the JDK/JRE is already
installed and not replace such common components as
the Control Panel applet with the earlier version?No, I doubt that. But you could install them the other way around, uninstalling 1.5, then then first installing 1.4.2 andf then 1.5 again.

JDK/JRE Version support for Oracle Lite

Hi,
We have developed an application using jdk 1.4.x which also using Oracle9i Lite 5.0.2 release as a database. Application behaves normal except while closing it throws java exception (Exceptio Guard Page Exception) error.
Is it because of the JDK Version we are using? What is the JDK/JRE version level supported by Oracle Lite.
Thanks
Krishna

Right
I got the same problem too.
When my program and oracle 9i lite is running under JRE1.3.1, everything is ok.
However, when i migrate the jre to 1.4.x, the program must fail and report DLL exception after closing.
So trouble~!

TZupdater for the Java Runtime Environment for jdk/jre 1.6

B"H
Hi,
I need the TZupdater for the Java Runtime Environment for 1.6, unfortunately the only one that I can find on the Oracle/Java site is :
Java Time Zone Updater Tool 1.3.57
The TZUpdater tool is to enable an Oracle JDK 7 or JRE 7 user to patch their installation with the most recent timezone data
Can someone please point me to the relevant link for JDK 6 or JRE 6
Thank you in advance
Yechezkel

Hello Yechezkel,
You download any version from this link
Timezone Data Versions in the JRE Software
This gives the JRE Update Release release and the corresponding TZUpdater Version

can sun jdk 1.5 for webstart and sapjvm co-exist on the same server?
please refer this thread.. it helps with some notes for your reference

Can OC4J 10 and OC4J11 support jdk 1.6?

Can OC4J 10 and OC4J11 support jdk 1.6?

No not really. You will have to check above mentioned Oracle's certification matrix to make sure Oracle Application Server supports desired JDK on the platform you have.

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"

Have you any idea of what is happening with "jrew" in memory ?
We have had this problem for six month and we are totaly out of idea.
If you can give us any idea, we'll appreciate a lot.

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

Is javamail part of JDK/JRE

Can any one tell me whether JavaMail is part of JDK or JRE. If so, what is the purpose of providing it separately

But JDK may be providing some mailing utilities,
right? How is this utility different from the one
provided by JavaMail. What exactly is the advantage
of using JavaMailThe only thing the JDK provides for mailing is a very
old sun.* class that you're not supposed to be using
and that has very, very limited capabilities.
The advantage of using JavaMail is that it was designed
for sending mail and it supports everything you need to send
(and read) the most common types of email.

Iwcadmin error with JDK/JRE version

hi,
I encountered this problem when executing iwcadmin utility ./iwcadmin -V in SJM on Sun Solaris , an error prompt displays "
Java runtime at /opt/ca/sharedutils/JRE/1.4.2_09 is below minimum requirement of 1.5.0
Please make sure the Java runtime at standard location meets the
minimum requirement, or set JAVA_HOME to point to an installation that does.
here is the OS and other JDK / JRE path available in the system.
other jdk5 : /usr/jdk/jdk1.5.0_16/ or jre5 /usr/jdk/jdk1.5.0_16/jre
uname -srv
SunOS 5.10 Generic_137137-09
How can I make it use the jdk5/jre5 or at least temporarily during my user session?

Not sure which shell you are using but ....
CSH: set JAVA_HOME=/usr/jdk/jdk1.5.0_16
KSH or BASH: export JAVA_HOME=/usr/jdk/jdk1.5.0_16
then just invoke "iwcadmin"

JDK/JRE release announcement list?

I've looked high and low, but cannot find anywhere that is a definitive e-mail release announcement distribution point for the JDK/JRE (announcements only, not a bunch of additional "newsletter" content). [email protected] doesn't have such a list, and I can't find something similar on SDN or via searching java.sun.com.
Am I simply overlooking something?

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

SDK, JDK, JRE,

Hi everyone,
I'm very very new to Java etc. I want to learn JSP/Servlets.
Now I see I need to install software, I see things as SDK, JDK, JRE what is this all? What do I need?
I tried to find the info but there is so much information I'm not sure what I'm looking at. So I thought if there is any expert here that can clearly explain what the difference is between SDK, JDK, JRE.
Thank you very much!!
Regards,
Steven.

JDK:     When you download Java, you will get a couple of tools: the compiler, a tool to generate documentation, a tool to change security settings and a tool to run compiled Java programs (class files). All of these tools bundled together is called the Java Development Kit (JDK). If you want to create your own Java program, this is what you need. Later we will show you where you can get the JDK, and how you should use it.
SDK:      Since the introduction of JDK version 1.2, a different name is used for the Java Development Kit: Java 2 Software Development Kit (SDK).
JRE:      The Java Runtime Environment (JRE) is part of the JDK. It contains only those tools that are needed to run java programs. It does not contain the compiler. Therefore it is a lot smaller than the JDK. If you develop a Java program for someone else, you are allowed to give him the program and the JRE so he can run your program. Officially you are not allowed to distribute the JDK, but anyone can download it freely from internet. The JRE for Windows also contains the Java plugin.

To get Java set up, follow the tutorial "First Cup of Java":

Difference between JDK/JRE

Guys,
I need to know the difference between JDK and JRE? When should one use JDK and when one should use JRE. What is the advantages/disadvantages of using one over other.
Cheers,

Shutt up guys... one person is to know some thing about JDK/JRE, and you.....
Any way
Hi tnischal!
Your question was about JDK/JRE
JDK = Java Development Kit
JRE = Java Runtime Environment
JRE is a comolete Setup of J2sdk1.4.1(LatestVersion of JDK(1.4.1) with other requirements to use this version included JDK1.4.1,JavaWebStart,SunJVM,Java2PlatForm, and all other needs for it.
while JDK is only the Software Development Kit. Previous versions of JDK than V1.4.1 did not need the all Runtime Environment for JDK, You just copy the JDK Folder in your machine and use it
But you can't use JDK1.4.1(fully) without other requirements of use it.
Hope you got the difference now.

Difference between JDK , JRE J2EE

Hi
Would anybody just show the difference between JDK , JRE , J2EE , and J2RE
Thanks alot

JDK - Java SDK from Sun
JRE - Java Runtime Environment
J2EE - Java 2 Enterprise Edition
Basically, JDK is J2SE, Java Standard Edition. You need this to develop and to compile standard Java software. JRE allows only execution without any special components. J2EE is extension to J2SE. It contains Business or Enterprise components like Java Beans.
