evaluating string expressions in Java

All,
I am looking at usage of javascript eval method from within a java application to evlauate javascript expressions. Its works with JSObject, but the problem is I cant figure out how to obtain an instance of JSObject from a Java Class which is not an applet.
I dont want to use anything that will increase the size of the app. by more than 10 KB - why should I include complete JS engine if I all I want to do is eval!
Any help would be greatly appreciated !
thanks,
Y

There is nothing of the kind in the Java platform itself. You could write an expression evaluator yourself, or hunt down one that fits the bill; there are plenty around, varying from simple and small ones that consist of a single java file to complete scripting languages such as JavaScript, BeanShell, Jython or JRuby; see Programming Languages for the Java VM for more details than you ever wanted to know.
