Others have asked this question but the answer is usually the same and not helpful to my problem. I installed JDK, and added C:\Program Files\Java\jdk1.7.0_25\bin to the path system variable. I checked, jps.exe is in that directory. I restarted my computer but still have had no luck. When I run jps I get the error:
'jps is not recognized as an internal or external command, operable command or batch file'
When I run C:\Program Files\Java\jdk1.7.0_25\bin\jps.exe on the command line it works fine. Working in Windows 7.
Mildly obvious mistake, but I realize that I had spaces in between the directories in my path and that caused them to not be recognized. So I had %OTHER_PATH%; C:\Program Files\Java\jdk1.7.0_25; %ANOTHER_PATH%, which I just had to switch to %OTHER_PATH%;C:\Program Files\Java\jdk1.7.0_25;%ANOTHER_PATH%
Your JDK bin directory does not exist in PATH variable.
To add this you need to do below steps.
Go to "Control Panel >> System >> Advanced system settings >>
Environment Variables
Click 'Path' from System variables
Click Edit.
Now add the path "C:\Program Files\Java\jdk1.8.0_72\bin"
Now open command window and write jps. It will work now.
In addition to the above solutions, still if you have issue with jps command, Please check whether the default system installed java(JRE) path is already available in the Path variable.
My case i faced the same issue and observed the following path already available in the path variable.
"C:\Program Files (x86)\Common Files\Oracle\Java\javapath"
So I had to change the position(move up) of my new JAVA_HOME path, new JAVA_HOME path is above the default oracle javapath.

I want to use elastic search with my PHP application.
after running service install command , I am getting fallowing error.
C:\elasticsearch-0.90.10\bin>service install
JAVA_HOME points to an invalid Java installation (no java.exe found in "C:\Progr
am Files (x86)\Java\jdk1.7.0_25\bin"). Existing...
Open up and Look into the service.bat file:
It searches for:
%JAVA_HOME%\bin\java.exe
hence your %JAVA_HOME% should not include bin in it.
A workaround if you do not have privileges to set up the environmental variables:
open the service.bat file,
a) Remove the line:
if NOT DEFINED JAVA_HOME goto err
b) Replace %JAVA_HOME% with your java jdk path, something like: C:\Program Files\Java\jdk1.7.0_51
Note: This is just a workaround which works all the time.
from your error message we can see your JAVA_HOME points to
C:\Program Files (x86)\Java\jdk1.7.0_25\bin
while it should point to
C:\Program Files (x86)\Java\jdk1.7.0_25
I think the error message is fairly descriptive , you should look in this folder
is java.exe there ? If not then your JAVA_HOME environment variable to point to the correct installation
heres a page showing how to do that
https://confluence.atlassian.com/display/DOC/Setting+the+JAVA_HOME+Variable+in+Windows
1st hit on google.
Either JAVA_HOME points to the wrong location or you don't have Java installed. Check and see if there's an install of Java in the location specified.
Also note that the JAVA_HOME variable should point to the root of the Java install not the /bin folder. This is being added by the program you're executing.
To change the JAVA_HOME variable to test further use the following in the command prompt:
set JAVA_HOME=c:\xxxx
Once you've established the correct value to use this can be permanently changed in Control Panel>>System>>Advanced System Settings>>Advanced>>Environment Variables
set JAVA_HOME=C:\Program Files (x86)\Java
Above must fix the issue, I came across the same issue while installing the elastic search.
i gave a try by giving "bin" part of path but it did not work, so i just give the top folder "java" in path, it worked.
Just to add my own experience.
i was setting JAVA_HOME using tab autocompletion.
It ends up something like "C:\Program files...:" and it didn't work saying that it cannot find the java program. I solved typing the JAVA_HOME path in the set command without using tab completion. The problem was probably related to the " in the env variable
I'm running Windows 8 and I can not get javac to work.
I have set my PATH in environmental variables to
C:\Program Files (x86)\Java\jdk1.7.0_17\bin
I have tried both with and without ';' but to no avail.
I recently had this issue on my desktop and adding ; worked but it's not in this case.
I have made sure that javac does exist in the bin too.
Any suggestions on fixes would be greatly appreciated.

And the exact error is: 'javac' is not recognized as an internal or external command, operable program or batch file.
As far as I can see you have the JRE in your PATH, but not the JDK.
From a command prompt try this:
set PATH=%PATH%;C:\Program Files (x86)\Java\jdk1.7.0_17\bin
Then try javac again - if this works you'll need to permanently modify your environment variables to have PATH include the JDK too.
Go to my computer;
Right click properties;
Go to advanced system settings;
Go to environment variables;
In user variables for user click on new(top new button, not on system variables);
Set variable name as: Path
Set the value of that variable to: C:\Program Files\Java\jdk1.7.0_76\bin
Click ok;
Click ok;
Click ok.
Now you're set. Type javac in cmd. All javac options will be displayed.
EDIT: As #MediaMaker pointed out, after completing the above steps, you need to open a new command prompt for it to work.
Easiest way: search for javac.exe in windows search bar. Then copy and paste the entire folder name and add it into the environmental variables path in advanced system settings.
I'm searched many answers that suggest me to type in cmd:
set path = "%path%;c:program files\java\jdk1.7.0\bin"
but this is WRONG!
the right solution is that you leave "set" and just type
path = %path%;c:program files\java\jdk1.7.0\bin
P/s: of course you have to replace "jdk1.7.0" folder by your current java version folder. This works well on win 7 32bit, but I think it also works on win 8 - try it!
Start off by opening a cmd.exe session, changing directory to the "program files" directory that has the javac.exe executable and running .\javac.exe.
If that doesn't work, reinstall java. If that works, odds are you will find (in doing that task) that you've installed a 64 bit javac.exe, or a slightly different release number of javac.exe, or in a different drive, etc. and selecting the right entry in your path will become child's play.
Only use the semicolon between directories in the PATH environment variable, and remember that in some systems, you need to log out and log back in before the new environment variable is accessible to all environments.
You don't have jdk1.7.0_17 in your PATH - check again.
There is only JRE which may not contain 'javac' compiler.
Besides it is best to set JAVA_HOME variable, and then include it in PATH.
do this:
1. run CMD (WIN+R then type in CMD)
2. Type this:
set PATH=%PATH%; java installation path\bin
Replace "java installation path" with the directory JDK is installed in, such as C:\Program Files (x86)\Java. Be sure to add the \bin after the JDK directory, because this points to "javac" and "java" (BIN stands for "binaries")
This way, you can run the Java compiler from anywhere. It is impossible to CD to the JDK directory because it has a space in Program Files, and DOS will not let you CD to these directories.
My javac command is not working.
"javac is not recognized as an internal or external command, operable program or batch file."
-java version WORKS
I've tried setting classpath successfully in command prompt. SET CLASSPATH "C:\Program Files\Java\jdk1.7.0_09\bin";
Ive adding it in environment variables. ;C:\Program Files\Java\jdk1.7.0_09\bin ;C:\Program Files\Java\jre7\bin
Ive checked the bin folder java.exe is there aswell as javac.exe.
^ Tried all of these still doesn't work. I've also restarted command prompt still does not not work.
Why is not working?
You're using the correct path apparently, but you should assign it to the PATH variable, not to the CLASSPATH variable.
You're trying to set the access path to the executable files, not to the class files.
Just do this
In the same dialog, make sure that JAVA_HOME exists in your user variables or in the system variables and it is set to the location of your JDK,
e.g. C:\Program Files\Java\jdk1.5.0_02 and that %JAVA_HOME%\bin is in your Path environment variable.
Just set JAVA_HOME to
C:\Program Files\Java\jdk1.7.0_09
After adding the path to the jre7\bin-Folder to the PATH-Variable, you need to restart your Computer in most cases.
Did you tried to create a JAVA_HOME variable? The value should be the path of the java without the bin.
Also, try to open Eclipse.
If nothing helps, the last thing that you can do is install netbeans, it will configurate everything.
I'm new to java and eclipse. I even saw this type of query on this website. But I have applied all those methods and it was also helpful. But when I try to open eclipse, it is not opening:
This is my path for java
C:\Program Files (x86)\Java\jre6
this is where my eclipse is
C:\Users\New folder\eclipse
But when I run the eclipse I'm getting an error
"A java rumtime environment(JRE) or java development kit(JDK) must be
available in order to run eclipse. No java virtual machine was found
after searching the following location: C:\Users\New
folder\eclipse\jre\bin\javaw.exe javaw.exe in your current path"
Please tell me the possible solution.
Thanks in advance!
If you have installed jdk then Eclipse won't have any issue to start. I think you just have installed JRE to run java programs. You need to install JDK.
To check whether you have installed JDK. Check Path C:\Program Files (x86)\Java. Your Java directory should contain directory jdk1.6.., If you don't have this directory there, search it at other places. If you did not find directory then you didn't install JDK.
Download JDK from here.
You should set JAVA_HOME and JRE_HOME variable. http://www.javawebonline.com/java-se-programming/beginners/java_home-jre_home-environment-variables/
And another suggestion is you should move your java home to another location and test your path to java such as
C:\Java\jre6
instead of
C:\Program Files (x86)\Java\jre6.
Go to C:\Users\New folder\eclipse
Open eclipse.ini file with text editor and add the javaw location there
( right after -vm part ) like so:
-vm
C:/Program Files/Java/jdk1.6.0_33/bin/javaw.exe <--- change to your path
-vmargs
Open the command prompt by pressing Windows+r, type cmd and press Enter.
Type javac and check the output.
If it gives all the options and usage, then you have configured the PATH vairables correctly, or else you have not set them up correctly.
Try it by checking the value at the command prompt.
NOTE
You need to open a new command prompt each time you change the environment variables.
If you have two Program Files folder in your C: drive
such as
C:\Program Files
C:\Program Files (x86)
then try to put your java inside
C:\Program Files
instead of C:\Program Files (x86)
It seems you are running 64 bit eclipse in 64 bit operating system. If you are running 64 bit eclipse then you need 64 bit JDK. Please install 64 bit JDK and run eclipse.
What can I do when I keep receiving the error
'javac' is not recognized as an internal or external command, operable program or batch file
when I want to compile my jar or .class file?
Thanks
Make sure %JAVA_HOME%/bin is on your %PATH% (or $JAVA_HOME on the $PATH in *nix).
It means that it is not in your path. You have the following options:
1) Change to the directory where javac lives before calling it.
2) Use the full path to javac when making the call, e.g. C:\java\jdk1.6.0_12\bin\javac ...
3) Add the javac directory to the PATH environment variable
This just means that javac isn't in your PATH variable.
On Windows, you just have to add the folder that contains javac.exe to the PATH environment variable (Win+Pause/Break).
On Linux/Mac/Unix, just append that directory to $PATH in .bashrc or similar.
The error that you are seeing is generated by Windows, and isn't specific to Java. That error means that you typed a command and Windows could not find the command by that name.
The easiest way of rectifying the situation is to ensure that Java is properly installed in your system's PATH.
First, ensure that you have a JDK installed (and not just a JRE). Your next best bet is to add an environment variable called JAVA_HOME and point it at the base install directory for the version of Java that you installed.
Next, modify your PATH environment variable by prepending the string %JAVA_HOME%\bin; to whatever is already in your PATH. If you look at the contents of that directory, you will see that javac is in there (along with a number of other Java development tools).
You have to install JDK (which includes javac compiler) and ensure that it's in the path. See http://java.sun.com/javase/downloads/index.jsp
Common Error Messages from SUN Tutorial page
Step 4 (Update the PATH variable) of the JDK installation instructions explains what you should do to make it so that you can just type javac in the command prompt window.
The link below gives a step by step explanation on how to set up java_home and path variables.
JAVA_HOME setup
Even if I had
JDK installed
JAVA_HOME defined
%JAVA_HOME%\bin present in my %PATH%
I still had this error. I resolved it by eliminating the JRE from my path variable. It was put before JAVA_HOME, has no javac. It seems Windows can't find javac in JAVA_HOME\bin in this case.
For Windows
Control Panel > System...Then click Advanced System Setting (left pane)...then popup window will open...then click Environment Variables...Then another window will open...click New and add enter information below
Variable name: PATH
Variable value: C:\Program Files\Java\jdk1.7.0_45\bin [*make sure this is the right path for you]
Then it should work
Check whether you have JDK installed; if not installed, Install
If JDK is installed, navigate into the bin folder of the installation, and try to execute javac.
If javac executes, proceed (+:
If javac does not execute, check your system path, and java path, and return to 2 above!
