How to import java packages into js file

Question

I was wondering how to import my java packages into a js file, and then call the class methods on the created object.

The reason I need to import is the desire to get data from a connection to my database regarding dates, and I have a class that allows me to do this. So I need to import the package, then create a class object, and then call the methods on my object.

I would be grateful for your help, Thanks, John

Calling java methods from javascript is not possible.

JSP file:

function doSomething {
   <% SomeClass.someMethod(); %>
}

<%!
class SomeClass {
  public static void someMethod() {
    // 
  }
}
%>

someMethod will not start when doSomething is called, but it will work when jsp generates a response.
