Applets can read certain system properties by invoking System.getProperty(String key)

 java.version       Java version number 

 java.vendor        Java vendor-specific string 

 java.vendor.url    Java vendor URL 

 os.name            Operating system name 

 os.arch            Operating system architecture 

 file.separator     File separator (eg, "/") 

 path.separator     Path separator (eg, ":") 

 line.separator     Line separator 

 java.class.version Java class version number 

But applets are prevented from reading these system properties (for security reason):

 java.home          Java installation directory 

 java.class.path    Java classpath 

 user.name          User account name 

 user.home          User home directory 

 user.dir           User's current working directory 

To read a system property from within an applet, simply invoke System.getProperty(key) on the property you are interested in.

 String s = System.getProperty("java.vendor");
