Cannot open Eclipse [Java Path Issue] [message #908224]

Hi,

I have a problem with eclipse.
I've download and installed ''jdk-7u7-windows-i586'' and extracted ''eclipse-jee-juno-win32-x86_64''
I want to start coding and I chose the game Runescape as a test subject/first step.
Everytime I try to open eclipse this message pops up ; (see attachment)

Any idea on how to fix it? I've tried creating the path and copied the javaw.exe from my Java directory but another error popped up.

-Thank you in advance.

Roro,

You're asking questions in the middle of the night (in Europe and
certainly after working hours in NA) and expecting answers in less than
3 hours? Did you actually install an appropriate JDK on your machine?
In any case, copying just the *.exe isn't sufficicient because that exe
isn't going to find the libraries it needs. You should use the -vm
argument (which you can also put in the eclipse.ini so you don't have to
keep specifying it) to point at where the exe actually is.

What is the right way to install JDK?
I installed it by default, it's in C:\Program Files (x86)\Java\
The -vm didn't work whatsoever.

When you get a JDK from Oracle, you install it. It sets things up in
(at least on my machine):

c:/Windows/System32

You can try java.exe -version there to see which one is there. That's
the one used by default. If it's not the right one, it's not going to work.

An alternative to specifying the -vm arguments (what exactly did you
try?) is to copy the jre folder to the folder that contains your
eclipse.exe. If you want the JDK source, be sure to copy the JDK's
src.zip into that jre folder too.

Try specifying the full absolute path name of the javaw.exe.

NetBeans is a piece of cake, however, it's not what Java application
developers use to develop software in.

Have you looked at http://wiki.eclipse.org/Eclipse.ini

There's more than 1 javaw.exe

There's 2 javaw.exe

One in C:\Program Files (x86)\Java\jdk1.6.0_33\bin
The other in C:\Program Files (x86)\Java\jdk1.6.0_33\jre

What do I do next?

P.S.
I had eclipse and used it once (months ago) I didn't have this problem.

Oh god...thank you so much.
I can't believe I fell for this.
I actually believed I downloaded the 64bit, but it seems not.
