Hi,
InvokerServlet.java is a file which is internal to
the Java Web Server if i am *right*.I feel the error
is somewhere in the LoanCalculator.java file itself.
The classcast Exception could arise because of many
situations: One of them *primarily* being casting an
object to a subclass which is not an instance.
For example:
------------
1)A.java
public class A
{
}
2) B.java
public class B extends A
{
public static void main(String args[])
{
A a = new A();
B b = new B();
// Below piece of code compiles successfully but at
run time it gives a ClassCastException.
b=(B)a;
}
}
-----------
Take a look if you are doing anything like above in
your code.
