I downloaded and installed jdk7 on my mac and wanted to find out the actual content of it so that I can install it in eclipse. There is no jdk 7 related content in /System/Library/Java.
You need to let know eclipse where the JRE 7 is, and you can do in this way :
Go to Preferences pane of eclipse
Open Java on the left pane
Click on Installed JREs
Add Button ---> Standard JVM and Next
Insert : /Library/Java/JavaVirtualMachines/jdk1.7.0_06.jdk/Contents/Home in the JRE Home TextBox
Next and Save the configuration
You need to add JDK 7 to the list of installed JREs in Windows-> preferences -> java -> installed JREs.
It is located in /Library/Java/JavaVirtualMachines/...
So in /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home you can find the bin folder, lib folder etc.

I am using Eclipse Luna (Java EE IDE). I need to add jdk because my project is been converted to maven. Whenever , I install maven console gives an error
No compiler is provided in this environment. Perhaps you are running
on a JRE rather than a JDK?
So i used Preference>installed jre's. However , when i am trying to change JRE to JDK by using Search button in Installed jre's. It shows me only JRE not JDK. Although , i am providing JDK path.
In short , I need to change my environment to JDK.
Thanks. Please help me out
In the preferences screen, remove the JRE listed there.
Add > Standard VM + Next > Directory + navigate to the jre directory inside jdk folder and Finish
If done right then JRE Home should look like "C:\Program Files\Java\jdk1.8.0_05\jre", NOT "C:\Program Files\Java\jre8"
Next, make sure you have the new JRE System Library listed under the Libraries tab in Java build path and in the Java Compiler (right click on project > properties) you define enable project specifics and set Compiler compliance level to the version you want.
Hope it helps.
Just open: Window-> Preferences ->Installed JREs and press SEARCH. Chose a folder and eclips find all avaliable jre and sdk.
I recently downloaded eclipse Kepler and JDK 1.7 to my Debian-machine and setup eclipse to be in
/usr/local/bin/eclipse
and the JDK to
/usr/share/
When I work in terminal, I can start it just fine.
Now, I wanted to add a link to GNOME 3 applications menu. So I cat one of the files, and changed it accordingly. When I click on the icon in the applications-menu I am displayed with
"either a JDK or JRE must be present in eclipse/jre. java was not found in PATH".
Can I go around putting the JRE into the folder? How can I adjust the PATH when I use the applications-menu?
Add your eclipse.ini file:
--launcher.GTK_version

I install jre and jdk, then install Eclipse, I want to create new java project and run it with jdk. For another program I need rename jkd on jskd, in tip JRE in eclipse I can't choose jsdk, how to change this?
It's really difficult to understand what you are asking but it you want to select a JDK in eclipse:
Window -> Preferences -> Java -> Installed JREs -> Add -> Check your JDK
If you mean which JRE you want to use for your project, in eclipse this can be configured by going to the "project" menu > "properties" > "Java building path". In the "Java building path" you can define the "JRE system library".
I have a mac and I recently installed Java 7 on it. However, my question is, how do I let Eclipse (Juno) know about this installation. I went to the preferences menu and selected Java > Installed JREs to get to this screen
I've clicking the add button but I'm not sure what I need to add:
I would have thought that I should add the .jdk file but it eclipse doesn't like that.
For the latest version (07) you can type in /Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk/Contents/Home/
instead of using the directory... button
I've instaled the Java for Developer package provided from Apple for 10.7 and java apps are running fine
but eclipse cannot find the JDK root path and I cant either.
Anybody any ideas?
You can download the 10.7 Lion JDK from http://connect.apple.com.
Sign in and click the java section on the right.
The jdk is installed into a different location then previous. This will result in IDEs (such as Eclipse) being unable to locate source code and javadocs.
At the time of writing the JDK ended up here:
/Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home
Open up eclipse preferences and go to Java --> Installed JREs page
Rather than use the "JVM Contents (MacOS X Default) we will need to use the JDK location
At the time of writing Search is not aware of the new JDK location; we we will need to click on the Add button
From the Add JRE wizard choose "MacOS X VM" for the JRE Type
For the JRE Definition Page we need to fill in the following:
JRE Home: /Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home
The other fields will now auto fill, with the default JRE name being "Home".
You can quickly correct this to something more meaningful:
JRE name: System JDK
Finish the wizard and return to the Installed JREs page
Choose "System JDK" from the list
You can now develop normally with:
javadocs correctly shown for base classes
source code correctly shown when debugging
On newer versions of OS X you should find ALL JREs (and JDKs) under
/Library/Java/JavaVirtualMachines/
/System/Library/Java/JavaVirtualMachines/
the old path
/System/Library/Frameworks/JavaVM.framework/
has been deprecated.
Here is the official deprecation note:
http://developer.apple.com/library/mac/#releasenotes/Java/JavaSnowLeopardUpdate3LeopardUpdate8RN/NewandNoteworthy/NewandNoteworthy.html#//apple_ref/doc/uid/TP40010380-CH4-SW1
I have just ran into the same problem after updating. The JRE that is downloaded by OSX Lion is missing JavaRuntimeSupport.jar which will work but can wreck havoc on a lot of things. If you've updated, and you had a working JDK/JRE installed prior to that, do the following in Eclipse:
1) Project > Properties > Java Build Path > Select broken JRE/JDK > Edit
2) Select "Alternate JRE"
3) Click "Installed JREs..."
4) In the window that opens, click "Search..."
If all goes well, it will find your older JRE/JDK. Mine was in this location:
/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
For Mountain Lion, Apple's java is up to 1.6.0_35-b10-428.jdk as of today.
It is indeed located under /Library/Java/JavaVirtualMachines .
You just download
"Java for OS X 2012-005 Developer Package" (Sept 6, 2012)
from
http://connect.apple.com/
In my view, Apple's naming is at least a bit confusing; why "-005" - is this the fifth version, or the fifth of five installers one needs?
And then run the installer; then follow the above steps inside Eclipse.
You can download jdk6 here http://support.apple.com/kb/DL1573
Wish it helps
