I'm trying to work with JAVA in Eclpise (Helios) and I'm running on Mac OS X 10.6.7. When I try to open a new Java Project it tells me that I don't have any JRE installed.

Using terminal it says that the current javac -version is 1.6.0_22. Now, I read about specifying a path in Eclipse->Preferences->Java->installed JRE to Library/Framework/JavaVM/Versions/1.6/home the problem is that after "Versions" I'm finding only "aliases" and not folders. If I click on that, it tells me that the alias is not working.

So I'm stuck here: anybody has a solution?

I found a solution so I would like to share. Actually nothing worked, I ve also called Apple and they had no idea. So I ve downloaded Windows 7 and installed it on my Mac with bootcamp. Now everything works fine.

I saw this post solution!

It helped me solve my problem I had on my mac after a fresh install of leopard. Seems like these variables have to be set manually or so.

Click on project--> Build Path-->Configure Build Path...-->Libraries tab-->Click on Add Library button. Select JRE System library than select JRE if not found than you can specify your own JRE.I think this might help.

What is the PATH to the JRE file? Not something else, but the ~JRE~ (Java Runtime Environment) As needed for http://www.boonex.com/trac/dolphin/wiki/RayMediaServerInstallation

On my macbook pro I had the same problem: in an imported Java project, some libraries cannot found (like java.time).

I've tried some tutorials but at the end I solved installing the last JRE version and removing all old versions from System/Library/Java/JavaVirtualMachines

Hoping to be useful

The answer is to get the Eclipse-Oxygen. After watching a bunch of youtube videos and trying above hints nothing worked, I kept getting

'Launching HTTP Preview at localhost' has encountered a problem. Could not find JRE executable.

Then I saw this post where Nitin Dahyabhai writes it is a Mac-specific bug that is fixed for Eclipse-Oxygen

I uploaded Eclipse-Oxygen (Eclipse IDE for Javascript and Web Developers) using eclipseinstaller by Oomph--- and LO and BEHOLD preview of my html page was immediate, no set up required!

Sorry if it doesn't work on a mac (got no way to check), but since it's a Unix system:

in the terminal, execute which javac

Strip /bin/javac from the output and you have the path that eclipse needs

  • @Jordan ok, but /usr/bin/javac is probably just a symbolic link. So you need to do `realpath /usr/bean/javac` and do the above with the output. See [this page about `realpath`](http://www.cyberciti.biz/faq/unix-linux-bsd-find-real-physical-path/) – Sean Patrick Floyd Nov 11 '11 at 13:08
  • Huh. Looks like OS X doesn't even have the `realpath` command (although there's a man page for it, oddly). Using `ls -l` shows that it points to `/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/javac` so I suppose it'd be `/System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/` But I think that's not the correct path for OS X anyway; tried it in Eclipse and it doesn't seem to work. – Jordan Reiter Nov 11 '11 at 13:44
  • @Jordan no, I'm pretty sure /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/javac is another symbolic link. try ls -l on that, too – Sean Patrick Floyd Nov 12 '11 at 14:10
