How to Set Environment Variables in Windows

Hi Guys,
You know that we can retrieve the environment variables using System.getProperty("JAVA_HOME"); like this. It is easy.
Can anyone tell me how to create an environment variable using System class or is there any alternate java API to create environment variable. Please let me know.
My requirement is that I want to create the environment variable as follows
DEV_HOME
D:/Java/DEV

Are you talking about Java System properties (get and set through System.get/setProperty) or Environment Variables (read-only, get through System.getenv)?
You can set the former, not the latter (unless you start a new process through Runtime.exec(), for which you can specify a custom environment.

Path and ClassPath:
PATH
In Windows 9x you would set it up in the autoexec.bat file
ie.
SET PATH=%PATH%;c:\jdk1.4.2\bin\;
where c:\jdk1.4.2\ is the path where you installed Java.
In Windows 2000 and XP
Right click on My Computer->Properties->Advanced Tab->Environment Variables... Button.
If you see a PATH in System Variables, click that and edit it. If you don't, you will need to create a new System variable.
It should look something like this:
%SystemRoot%\system32;%SystemRoot%;c:\jdk1.4.2\bin\;
Any querry email me to [email protected]

Hi,
set the env file in profile of unix user.
if your shell is bash shell, then edit the user .bash_profile with env file. If your's is bourn shell, edit the user .profile
for example,
i have PROD as the database SID
/oraprod and /applprod are the base mount points of database and application tiers respectively.
erpserver is the hostname of R12 (single node)
(1) Database Tier:
login as oracle user
$vi .bash_profile
. /oraprod/db/tech_st/10.2.0/PROD_erpserver.env
save the file
(2) Application Tier:
login as applmgr user
$vi .bash_profile
. /applprod/apps/apps_st/appl/APPSPROD_erpserver.env
save the file

How to set Environment variables........???

I installed j2sdk in my system.....
i want to know how to set env variables...?

Which ones, what for? Did you check whether some are already set?
Forget about the classpath variable, if you want to add that. Use the command-line arguments.
And which OS?

Setting Environment variable in windows xp

Hi all,
I am trying to run a java program in textpad, which is installed in windows XP, but i am getting the following error.
java.lang.NoSuchMethodError: main
Exception in thread "main"
Can anybody tell me, how to set the environment variable in the control panel.
Thanx,
Guddu

java.lang.NoSuchMethodError: main
Exception in thread "main"This error is NOT caused by an environmental variable mis-configuration. It means you did not define a main method correctly, or you are trying to run a class as an application and it is not an application.public static void main(String[] args)

How to set environment variable?

Hi,
I just succeeded starting up an external executable by using nativeprocess.
Now I have to set the portnumber as an environment variable.
After setting this portnumber, I can send queries to the executable.
But I don't now how to set this environment variable.
You can see my try in bold:
Starting the executable (an extract of the code):
public var portnumber;
file = file.resolvePath("C:\\Program Files\\CM Synergy 6.3\\bin\\start_dbase.exe");    #start executable
process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, getportnumber);    #get portnumber as output of the executable
The next step is to define the variable portnumber:
file = file.resolvePath("C:\\WINDOWS\\system32\\cmd.exe");
processArgs[0] = "/C";
processArgs[1] = "set";
processArgs[2] = "portnumber=";
processArgs[3] = portnumber;
When I try to print out all environment variables, portnumber is not in:
file = file.resolvePath("C:\\WINDOWS\\system32\\cmd.exe");
processArgs[0] = "/C";
processArgs[1] = "set";
If I replace the last executable with my real command (running the query), the executable is giving the error that my portnumber is not set.
Is it possible? I have also tried it with setx.exe. Even running a python script where I set os.environ is not working.
I have the feeling that the command is executed but that the variable is not remembered for the next executable.

Hello Martin,
Thanks for your input. I have tried what you suggested but it didn't work. I will post my source code. Perhaps I'm doing something wrong. After setting my variable portnumber, I would normally run a query. Instead of running the query, I'm writing out the environment variables. Unfortunately, portnumber is not in the list . I also tried using "setx" insetad of "cmd.exe set" but without any difference.
    public var portnumber;
    public function run_query():void
        var file:File = new File("C:/WINDOWS/System32/cmd.exe");
        var si:NativeProcessStartupInfo = new NativeProcessStartupInfo();
        si.executable = file;
        var processArgs:Vector.<String> = new Vector.<String>();
        processArgs[0] = "/C";
        processArgs[1] = "set";
        nativeProcessStartupInfo.arguments = processArgs;
        var process:NativeProcess = new NativeProcess();
        process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
        process.start(si);
    public function set_portnumber():void
        var file:File = new File("C:/WINDOWS/System32/cmd.exe");
        var si:NativeProcessStartupInfo = new NativeProcessStartupInfo();
        si.executable = file;
        var process:NativeProcess = new NativeProcess();
        process.start(si);
        process.standardInput.writeUTF("set portnumber="+portnumber+"\n")
        setTimeout(run_query, 1000);
    public function onOutputData(event:ProgressEvent):void
        var process:NativeProcess = event.target as NativeProcess;
        textReceived.text += process.standardOutput.readUTFBytes(process.standardOutput.bytesAvailable) + "\n";

Your files should come in a folder with the name "Javax" and subfolders right?
What you can do is to paste the file "Javax" in your folder of your JDK installation.
For example, I have installed my JDK in C:\Java\jdk1.3
I added one new folder in C:\Java\jdk1.3 called classes.
Then I would put the Javax folder in classes.
PS : We add one new folder called classes so that in future when you want to add new classes you can just into this folder.
Then in your enviroment settings, simple point to C:\Java\jdk1.3\classes;.;
This works for me. Hopefully you will no problems!

How to set environment variables in mac mavericks for all users

Can someone here tell me the file to set JAVA_HOME environment variable for all users?
Thanks!

nara999999,
the file in which to set the environment variable depends upon the login shell of each user. Presuming that every user has bash as his login shell, and that the environment variable will be needed only in interactive shells, then the file to edit will be /etc/bashrc; if the environment variable will also be needed in non-interactive shells, then /etc/profile should be edited instead (and this will also cover users with either sh or zsh as their login shell). If ksh is used as a login shell, then /etc/ksh.kshrc will need to be edited. If csh or tcsh is used as a login shell, then /etc/csh.login will need to be edited.

Mountain Lion: how set environment variables

Am I correct that for Mountain Lion, if not earlier, the only way to set environment variables at the system level is to use (or create) a file /etc/launchd.conf that contains commands such as:
setenv CATALINA_BASE /opt/local/share/java/tomcat6
(That does seem to work as expected.)
If so, how does one do this by referencing the value of something else, e.g., to set JAVA_HOME? I tried
setenv JAVA_HOME $(/usr/libexec/java_home)
but then in Terminal if I run
echo $JAVA_HOME
I just get back $(/usr/libexec/java_home).
By contrast, if I put that same setenv JAVA_HOME $(/usr/libexec/java_home) command into my ~/.profile, then the result of echo $JAVA_HOME is the actual value referenced, namely, /Library/Java/JavaVirtualMachines/jdk1.7.0_15.jdk/Contents/Home.

launchd is not a shell and does not peform expansion. You have to use literal expressions. But you can also modify the bash environment system-wide by editing the file /etc/profile.
But sudo emacs /etc/profile won't let me edit this file: it's read-protected, emacs says.
What permissions should I give it? Right now it's in group wheel, owned by root but with Read permission only.
P.S. And is it really a good idea to edit /etc/profile -- assuming I can suitably set the permissions to do so? Apple goes out of its way to try to hide this file: /etc is a link to /private/etc, e.g.

How to set a variable value on the BPC Data Manager

Hello BPC Experts,
I'm creating a BPC10 NW version demo environment for our prospect customer.
I made a data manager to import BW data into BPC model from BW cube.
I need to import just one month data into BPC from the BW cube that has more than one month data.
When I run the data package manually, I can select a member of the time dimension prompt and I can import specific month data I want.
But, in a case where the program (data manager) runs by JOB monthly,
I can't select a member of the time dimension prompt manually.
So I want to know how to set a variable value to the time dimension prompt from a system date etc. automatically.
Are there any way to set a variable value to the time dimension prompt on the data manager automatically from a system date?
Or, do you have any other solution to import just one month data into BPC from the BW cube that has more than one month data by the data manager running on JOB ?
(without selecting a member of the time dimension prompt of the data package manually)
Thanks in advance,
Keisuke

How to set a variable in portal session using web dynpro java.

Hi,
I have created a web dynpro application, which is running inside portal. I have created a role called "R1". Inside role R1, i have created 3 workset W1, W2 and W3. and inside each workset i have some pages and iviews.
My requirement is when user logins to the portal , and when he clicks on role R1 for the first time, a login page should come (so that we can do revalidation), and when he enters his password again in that login page , then only workset W1, W2 and W3 should be visible/accessible to him and after successful revalidation, if he clicks again on role R1, in that particular portal session, than that login page should not come.
for this, i thought i will set a variable in portal session, whenever user successfully revalidated himself, and if after successful revalidation he clicks again on role R1, i will check in doinit method of webdynpro whether variable is set or not (which i already set on successful revalidation), and if it is set then i will do Donavigation else i will present login page to the user.
Can anyone tells me how to set a variable in portal session using web dynpro java.
thanks
