At my company, i am connecting the user's computer via remote desktop and adding a parameter like that;

Clicking Start->Settings->Control Panel->Java and opening "Java Control Panel". At the "Java" tab, clicking "View..."

At the "User" tab, double clicking to "Runtime Parameters" column and adding "-Duser.language=en" parameter. And saving the changes.

Normally, i am logging into the user's computer one by one from my computer remotely and there are lots of computers of users to do that.

How can i do that via command line from my computer?

Attached a jpg file about the parameter..

We are using JRE 1.6.0_07.
OS : Windows XP Pro SP3

Best Regards,

you can use Windows admin tools to modify the Registry of each PC directly.

look under HKEY_LOCAL_MACHINE\Software\JavaSoft\Java Runtime Environment

Thanks at first...

The user's regional setting must be our language (Turkish). But, for working a program here it must be English (United States).So, that parameter force jre to use English. However, it is still turkish at regional settings.

I couldn't find a key about that parameter in the registry at my computer which added the parameter.

oh, well based on your reasons for making the change, you're much better off adding the parameter to the launcher for that specific application (rather than the whole Windows platform).  If you're not familiar with the launching mechanism for that particular application, the Vendor should be able to advise how to add a startup parameter.

At the link you gave previous post, there is an example below;

java -Dfoo="some string" SomeClass

So, mine should be;

java -Duser.language=en {class}

but i dont know which class i will use..

is your application an applet? if so, check this link to pass runtime parameters

if yours is an application, how do you launch your application? webstart or batch script?

TAI-: you should be able to determine how the application is being launched.  That's the key here.  If you can't tell ask the software vendor.

4) At the 'System variablers' section, click New button
5) Add "_JAVA_OPTIONS"  to Variable Name section
6) Add "-Duser.language=en"  to Variable Value section
7) To see the change, log off and then log in to windows again.
