I've just installed Eclipse on my new machine.

64-bit version, with 64-bit Java, 64-big JDK and 64-big JVM.

I've read here: http://wiki.eclipse.org/Eclipse.ini

However, my Eclipse.ini is all on one line like so:

-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120522-1813
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vmargs
C:\Program Files\Java\jre7\bin\javaw.exe
-Dosgi.requiredJavaVersion=1.5
-Dhelp.lucene.tokenizer=standard
-Xms40m
-Xmx512m


When saving, it says "Access is denied" I am the admin on this account, I am the only user account on this PC.

Does the above ini file look okay? That is where my javaw.exe is installed.

Rafy,

Squint harder at the eclipse.ini doc. You should instead have:

..
..
..
-vm
C:\Program Files\Java\jre7\bin\javaw.exe
-vmargs
..
..
..

Also, if you're going to develop in Java, you might just as well change
that path to point at an actual JDK (and not merely a JRE) because
you'll need it. However, you can point at your JDK via Window -> Java ->
Installed JREs whatever JRE is running Eclipse for you.

Hope this helps. Best of luck.

Im new too and trying to install the modelling-juno on windows 8

so trying to work from the folder extracted from the zip download. (c:\downloads\eclipse)

I add the
-vm
C:\Program Files\Java\jre7\bin\javaw.exe
and was shown an exit error 13
so
reading further
change to
C:\Program Files\Java\jre7\bin\client\jvm.dll
and get the OP's error
"Failed to load the JNI..."

or should i just copy both files to the eclipse folder?

INI
-startup
plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.200.v20120913-144807
-product
org.eclipse.epp.package.modeling.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
256M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
256m
--launcher.defaultAction
openFile
-vm
C:\Program Files (x86)\Java\jre7\bin\client\jvm.dll
-vmargs
-Dosgi.requiredJavaVersion=1.5
-Dhelp.lucene.tokenizer=standard
-Xms40m
-Xmx512m


So I wonder, since Java for Win8 is only the 32-bit version and I am trying to install the 64 bit version of Eclipse Modeling that there might be a conflict, is that a correct assumption?

Yup, that's right. You must pair Eclipse with the bitteness of your JRE.
If you're running a 32-bit OS, you can't run a 64-bit JRE and you can't
run 64-bit Eclipse.

I did instal the 64 bit win8 but apparently java doesnt install as 64-bit, which is frustrating since I am using Waterfox, a 64bit browser. Even my system information shows the 64-bit info.

This is from the Java FAQ:
Quote:

Why do I only get the 32-bit Java when I go to Java.com?
Java.com provides a Java version based on your browser and operating system (OS). If you are running a 64-bit version of Windows 8, you have access to 32-bit and 64-bit versions of Internet Explorer 10 on your system. The desktop version of the Windows 8 OS does not run in a full 64-bit mode (unless you have Enhanced Protected Mode in Internet Explorer 10 turned on), thus 32-bit Java is the default.


Quite obvious to me that Java did not read my system or browser correctly, but yet will not let me download or install a 64 bit version of it. We have a word for this kind of behavior in the gaming community - lame.

After more digging I found the right java version, seems the auto install just doesnt work right so have to download and install java, as they call it, offline mode.

And with that fixed, we have a winner. thanks

This is surprising to me, but then I don't do Windoz. So, you're saying
that no 64-bit Java will install on Windows 8? Radically surprising! No
wonder when W8 came out I told my wife she's headed next to Macintosh
(I'm a Linux guy myself).

Hope life gets better.
