I went to the Environment Variables in 'System' in the control panel and made 2 new variables. one for user variables and one for system variables, both name

JAVA_HOME and both pointing to

C:\Sun\SDK\jdk\bin

but for some reason, I still get the below error when running a java command...

BUILD FAILED

C:\Users\Derek\Desktop\eclipse\eclipse\glassfish\setup.xml:161: The following error occurred while executing this lin

C:\Users\Derek\Desktop\eclipse\eclipse\glassfish\setup.xml:141: The following error occurred while executing this line

Find JDK Installation Directory

First you need to know the installation path for the Java Development Kit.

Open the default installation path for the Java Development Kit

C:\Program Files\Java

There should be a subdirectory like

C:\Program Files\Java\jre6

Set the JAVA_HOME Variable

Once you have the JDK installation path:

1. Right-click the My Computer icon on

2. your desktop and select Properties.

3. Click the Advanced tab. Click the

4. Environment Variables button. UnderSystem Variables, click New.

5. Enter the variable name as JAVA_HOME.

11thanks. finally I realized that one has only to put the path to the jdk without /bin in the end (as suggested on alot of places). e.g.

C:\Java\jdk1.6.0_31 and NOT C:\Java\jdk1.6.0_31\bin ! salocinx Mar 20 '12 at 22:24

6God forbid there was an installer that did this step for you :) I just switched from the Enterprise version to the Community version and I was

convinced I downloaded the wrong thing because it was one-click on the Enterprise version :p w00te Apr 26 '12 at 18:25

Sometimes, the system varible changes does not take effect until you restart the windows. Andy May 30 at 9:42

What worked for me was adding the %JAVA_HOME%\bin to Path environment variable with the JAVA_HOME environment variable pointing to

the jdk folder

5+1 adding %JAVA_HOME%\bin to bath fixed my issue, and here I thought 'JAVA_HOME' would be enough on windows 7 Jakub Nov 29

Awesome, Thanks a ton. And yes, this is the correct answer - @Lucifer. Anand S Feb 19 '12 at 16:59

1Lucifer's comment about how to find the JAVA_HOME system variable, and YOUR comment about how to set the path, should solve this

problem for everybody. David Is Not Here Aug 31 '12 at 14:14

You need to set it to C:\Sun\SDK\jdk (Assuming that is where the JDK is installed - It is not the default) - Do not put the \bin in C:\Sun\SDK\jdk\bin. If

your app only runs when you are logged in as the current user then put it in the user variables - If it needs to run for all users on your system then put it in

System variables.

You might also need to add %JAVA_HOME%\bin to the path also (Also it depends on whether you run it from just the user or from all users, including

System)

http://javahowto.blogspot.com/2006/05/javahome-vs-javahome.html

Control Panel > Java, Java tab, click the View button. In Runtime Parameters, put:

-Djava.home=YOUR_PATH_HERE

Or when you execute Java you can add that command line switch to the command:

java -Djava.home=PATH SomeJavaApp

run eclipse as Administrator.

that solved my problem. I`m still digging for the logic behind it.

1I can't say I understand this exactly, but maybe eclipse is actually just giving the wrong error message here. When you run it as a non-admin, it can't

delete the .jar files or something and then falsely reports that it didn't find javac. Anyway, this solution worked for me too. Jess Jun 15 '11 at 23:02

In Eclipse: Window->Preferences->Java->Installed JREs

Use the search feature to make sure your latest Java installation is listed; then make sure it is the one that is checked. This should be a JDK not a

JRE.

You closed cmd and reopened it? Also it looks like you are pointed to the JRE not the JDK. Have you installed the JDK?

I have definitely installed the JDK and it's located in C:\Sun\SDK\jdk\bin which I have set java_home to. DerekApr 12 '10 at 2:43

I've even restarted.........a few times since........ DerekApr 12 '10 at 2:44

Still it seems to be looking in C:\Program Files\Java\jre6\lib\ c Can you do echo %JAVA_HOME% in your command prompt and see what it

reports angerApr 12 '10 at 2:46

in my command prompt, when I ran echo %JAVA_HOME%, it returned: C:\Users\Derek\Desktop\eclipse\eclipse\glassfish>echo

%JAVA_HOME% C:\Sun\SDK\jdk\bin DerekApr 12 '10 at 2:59

In what context are you running cmd.exe? angerApr 12 '10 at 3:13

While adding your Java directory to yourPATH variable, you might want to put it right at the beginning of it. I've had the problem, that putting the Java

directory at the end of the PATH would not work. After checking, I've found java.exe in my Windows\System32 directory and it looks like the first one

wins, when there are several files with the same name in your PATH...
