Hi,
For the above query i wanted to know whether i can access the system property explicitly through following code:
Properties p = System.getProperties();
		p.put("check_value", "true");
		System.setProperties(p);

now the property is returning null when i access it in different process/application with 
System.getProperty("check_value").

is there any way by which we can set the system property which is accessible to all the processes

That is not possible in Java. Your only solution as far as I know is to
call an external program, such as the system shell, and use that to set
environment variables. Java only holds a copy of the properties, so no
matter what tricks you try, you will not be able to affect the outside
world.

Liebe Gruesse,
