Setting System Class Path

[Natraj Gudla]

Hi,
Using the System.setProperty(key,value) , i can change the class path of the system..But is it permanent, or till the program execuutes...as i have seen that the class path changed with the help of setProperty is non-existent after the program terminates....Is there any way by which i can effect the changes in the windows classpath...

Changing the classpath system property absolutely does not change the environment variable $CLASSPATH / %CLASSPATH%. If you want a java program to change the classpath that other programs (or this one) will use in future executions you probably have to use some file I/O on the startup script of that program and change the -cp argument.
