Setting the kvem home system property

Hi guys i am experiencing a slight problem in this code that sets the system property for kvem home.It was working fine in netbeans 5.5 Beta version but after migrating the entire project to Borland JBuilder 2005 Enterprise the code report an error that it cannot find the method getProperties() in class System.Furthermore it also report a similar problem to the method random() in class java.lang.Math,it says it is not found.Can anyone related with this problem please help me.I am puzzled coz i don't know what to configure for this to work in JBuilder 2005.

//Setting the kvem home system property

Properties props = System.getProperties();

props.put("kvem.home","C:\\WTK23");

//Getting a random in

int x = (int)(Math.random()*20);
