I want to combine a bunch of utility functions in a single js file and call those functions in several other files.  Is there a capability in Rhino to achieve this?
 
Here is what I tried to do.
1) Created util.lib text file that has one simple utility function
function utilFunction1(str1){
 java.lang.System.out.println(str1+"\n");
}
 
2) Create .js file that utilizes scope to call the function in util.lib file
 
context = Context.enter(); 
sharedScope = context.initStandardObjects(); 
result = context.evaluateString(sharedScope, "util.lib", "<cmd>", 1, null);
fObj = sharedScope.get("utilFunction1", sharedScope);
functionArgs = "This is a test";
result = fObj.call(context, sharedScope, sharedScope, functionArgs);

3) When I run this in js shell, I see error:
js: "<cmd>", line 1: uncaught JavaScript exception: ReferenceError: "util" is not defined. (<cmd>; line 1)

If this cannot be done thro' Rhino, is there any other way in which this can be achieved?
 
Thanks
