What is path to JVM?

I'm trying to install a tool that requires that "the JAVA_HOME environment property is set to match the top level directory containing the JVM you want to use."
The example they give for bash is
JAVA_HOME=/whatever; export JAVA_HOME
And I can run that command without errors. However, I can't figure out what the path should be. I found an old post saying it should be /Library/Java/Home, but when I tried to run the shell script to build the tool, it said JAVA_HOME wasn't set.
I also tried /System/Library/Frameworks/JavaVM.framework and /System/Library/Frameworks/JavaVM.framework/JavaVM, but it still said JAVA_HOME was not found.
I can't tell whether the path is wrong, the command I used to set JAVA_HOME didn't work, or something else is wrong. Does someone know the path is 10.6.2 for sure? That would really help me figure out where I'm going wrong.

Sorry I don't know what the path should be, but is this tool run from Terminal or is it a GUI Mac app (i.e. launched by Finder)? Remember that setting a Terminal environment variable only affects programs started from that Terminal session, and setting a Terminal var will have no effect on a GUI app (even an app started from the command line with 'open', AFAIK). A script started from Terminal would read the Terminal vars, but if it's installing a GUI app it might be smart enough to look at the GUI environment.
To read your Terminal envr vars, just type 'set' at the Terminal prompt. If you do this in a new Terminal session, check the list to be sure your original Java install didn't already set JAVA_HOME. If so, and your new tool is a GUI app, just copy the Terminal var to the GUI environment.
To access your GUI envr vars see [Environment Variables|http://developer.apple.com/mac/library/documentation/MacOSX/Conceptua l/BPRuntimeConfig/Articles/EnvironmentVars.html] in the +Runtime Configuration Guidelines+ or take a look at [http://stackoverflow.com/questions/135688/setting-environment-variables-in-os- x].
As to what the path should be, it's probably the directory your Java installer wants to use when it asks you if you want to install in the default location or not. I guess you could run the installer up to that point and then cancel after you copy that path. If all else fails, find the JVM(s) and try the parent directory.
Btw, I'm not a Java programmer, only working from what little I know about OS X envr vars. So after you get JAVA_HOME set correctly, please don't keep the thread open to ask why the tool is making bad coffee, ok? We have some Java experts around here, but another Subject line would be the best way to get their attention.
Hope that helps!

What Version of Sun JVM has JDeveloper been qualified with?

We have a bug that appears in Java 1.5.06.
Code worked in 1.5.02.
Issue is in the swing library event handling.

What is virtual in jvm

hi friends.
i have a basic doubt. why java runtime mechanism is said to be virtual machine. Virtual means imaginary. what is dummy in jvm.
by vinod

It is virtual, because it hides the differences between each platform.
When you develop a java program, you don't have to worry about whether it is run on an Intel processor or a Sparc processor, Windows or Unix.
The Java program, presents the java developer with a "virtual machine", as opposed to a specific platform and processor.
Ps. Virtual does not mean imaginary. In this case, it means a common interface to many platforms.

Owen

What's in the JVM Process's Memory Space?

Hello
I'm noticing the following behavior on an NT system. On
application startup, I see
Total Heap 9 MB
Used Heap 5.5 MB
java.exe memory (from NT Task Manager) 36 MB
After a "login" operation which loads a few more
classes:
Total Heap 12.5 MB
Used Heap 8.2 MB
java.exe memory (from NT Task Manager) 53 MB
Heap memory leaks have been ruthlessly suppressed
(thanks to OptimizeIt and careful programming). The
behavior I do not understand is that the NT process
(java.exe) increased in size by 17 MB when the Java
heap increased by only 3 MB. The .jar file in which the
application resides is less than 1 MB, so this 14 MB
growth can not be attributed to new classes being
loaded.
Does anyone know what is going into the process
memory space of java.exe? It tends to grow larger
and larger.
Should I even care? Do I want a large allocation of
process memory for java.exe, or will that hamper
performance of machines with less physical memory?
Posts on related topics in this forum have sometimes
advocated allocating a lot of memory to the JVM with
-X options.
Thanks

Hello
I am facing exactly the same problem on NT. However, on 2000 Server this problem doesn't seem to exist. Are you, by any chance, using JNI? We are extensively using JNI in our Servlets and found that there is definitely some momory leak there. We could not figure out any substantial leak at Java end. In NT's "Task Manager" java.exe is always listed first and very rarely the memory usage seems to come down. On 2000 Server the performance is far better.

What would make a JVM memory size 1.9GB ?

This is on Solaris 2.6, JDK 1.2.2_05a, JDK1.2.2_07, possibly JDK 1.3 (it crashed).
WLS 5.1, SP8. With inline_instrs_jit=0.
This is the [heap] segment shown by /usr/proc/bin/pmap. This is native heap, it is
NOT the Java Heap.
I know it could be the Type 2 db drivers - but I doubt it.
With JDK1.3 we set -XX:MaxPermSize=128m - it crashes after an hour.
One part of the application creates its own threads for some parallel processing.
Is this a known
problem with the JVMs?
Any help is much appreciated.

Thanks for your attention -
We create lots of threads - up to five threads for each DB hit (i didn't

The multi-threading will be disabled/removed and tested later on today.
Both 'top'

I've read articles on the bea newsgroups about WL hanging on to threadreferences
so that the threads could not be GC'ed, but it sounded more like a customer's

Right now we are running with the 1.2.2_05a 'Debug' JVM with -verbose:gc

Eclipse can't find the path to JVM

I tried running Eclipse and got an error that said that it looked for Java in /usr/share/eclipse/jre/bin/java and couldn't find it, so it can't run.
I'm pretty sure both the JVM and JDK are installed, although running 'java' and 'javac' result in "bash: java/javac: command not found".
Thanks.

Do you have the files /etc/profile.d/{jre,jdk}.sh? Do they get sourced when you log in? They should. They are the ones that set up the various paths required to run java. I'd also have a look at /etc/profile. It should contain this part, that sources all files in /etc/profile.d:
# Load profiles from /etc/profile.d
if test -d /etc/profile.d/; then
for profile in /etc/profile.d/*.sh; do
test -x $profile && . $profile
done
unset profile
fi

Can't change path to JVM

Hello all,
I recently installed the latest JDK (jdk1.5.0_14), but when trying to start a server the path defaults to a previous JRE path (jre1.6.0_03), and so I get the error that there is no server VM in that directory.
I've added the JDK path to the environment variable (the original JRE path was not there at all), and even changed all references in the registry.
In the Java control panel I've added the JDK's VM paths (both the root bin and jre folders) for the JNLP on the USER tab, disabling the other JVMs, but can't do anything on the SYSTEM tab.
I'm inexperienced with Java so apologies if I haven't made any sense, or its a simple fix. I'm at a loss to know where it's picking up the path from, and any help would be appreciated.
Thanks
Matthew
**Edit. So actually not the latest JDK, just the one that was recommended. Can you run a JDK older than a newer installed JRE?**
Edited by: MattLeach on Feb 18, 2008 8:00 AM

1. which server are you using?
2. your server is referring JRE right, while installing the server you was gave the JRE path right, so try to change you JRE location in your server configurations, then your server will point to right JRE,

What the path tutorials don't tell you

Well I just learned about the multicolor paths. Not in any tutorial I've read yet.
And now Path times 2..
What I'm trying to do is learn the cintiq, and the ins & outs of the different PS functions. I'm currently hitting walls using PATH's to draw a simple lamp.. Base path 1, and shade - path 2.
Ok made the base, saved that path..This part's pretty much done. But I make many different layers, and want to draw a lot of those layers with the pen tool as paths.
Started a shade path [work path], went to stroke it, and the stroke, fill, new path, etc.. icons were all dead. Couldn't stroke it, fill it, or make new path. Actually I think the make new path button did work [once]. Still can't stroke the shade.
So, back to needing help that isn't that easy to find in the PS help.

Lots of free tutorials here:

What is technology behind jvm ?

can anyone tell me what are all technologies used to create JVM
means language etc.
please tell me the meaning of these lines
The Java programming language originated as part of a research project to develop advanced software for a wide variety of network devices and embedded systems. The goal was to develop a small, reliable, portable, distributed, real-time operating platform. When the project started, C++ was the language of choice. But over time the difficulties encountered with C++ grew to the point where the problems could best be addressed by creating an entirely new language platform.

There are varying JVMs for the varying platforms and from varying vendors. Which one are you interested in? And, once you know that, ask them.
If you are asking what the "standard" is, there isn't one, and it doesn't matter, regardless of what you may think of that answer.

What migration path from 10.g AS tiers to Fusion Middleware 11g AS tiers ?

Hi all,
We have purchased Oracle AS Enterprise Edition 10g a couple of months ago and
we are currently running the following tiers :-
- one Forms & Reports 10.1.2 AS instance,
- one infrastructure 10.1.4 instance for OID/SSO,
- one OC4J 10.1.3 instance for ADF applications deployment.
What would be the new tiers et their respective downloads to migrate to 11g with AS EE licences acquired and protected under OTS without having to purchase any new products or options ?
-Portal,Forms,Reports,.. 11g for Forms & Reports. (seems clear in the download list).
-What about ADF 11g deployment ? What to download ? (seems to be Web Logic Server in the Required Additionnal software section but not sure)
-What about OID/SSO ? What to download ? (it seems Forms & Reports 11g will work with OID/SSO 10.1.4 but what about ADF 11g apps deployed on WLS ? it is also going to be able register with 10.1.4 ?
Any clarification will be most welcomed.
Thanks.
Jean-Marc
Edited by: GCC team on Jul 2, 2009 4:23 PM

If you open the project in the 11g preview it will automatically update the metadata and generate the deployment XML in the new format. Alternatively you should be able to open the 10.1.3.3 metadata in the 11g preview's runtime.
The biggest issue you may encounter in the upgrade besides replacing the libraries and ensuring you are using JDK5 is the removal of the code deprecated in previous releases.

What career path to take after CCNA??

Hi All
I completed my ccna 2 years ago.I am working as 2nd line IT support but have no experience to any of the cisco products.Because all of the switches are allready configured and company dont let you touch the stuff unless you have experience.Because i need to renew the certification at the end of the year i am thinking shall i go for ccna security or not?
I have tried applying for all the cisco jobs but no luck so far??Please help........

You are in a proverbial spin-cycle: Which comes first, the chicken or the egg?
Companies won't hire you because you are not CCNA, for example. Now that you are CCNA they won't hire you because you don't have any experience. You can't have any experience because no one will hire you.
Unfortunately, in our line of work, we always require someone who has "certification" because we won't spend endless time explaining the concept of IP subnetting, for example. However, this does not stop anyone who claims to be CCNA/CCNP and designs a rack-full of HP servers and a 3750E as top-of-rack switch and hoping the PoE can power up the servers. Or someone who claims to be CCNA but doesn't know how to erase a config of a router.
Short story is this: Unless you can gain a foothold to the IT industry, studying for more certification is a waste of your time. I mean, CCNA Security is nice-to-have but unless you have three years of experience under your belt, it doesn't really mean much.
