About catching exception??

Question

Can anyone help me? I want to create a utility class which catches different sorts of exceptions and pass programmer generated messages through the request object back to the servlet controller which instantiates the utility class whenever an exception occurs.The contoller caches the exception in it's try-catch block and then instantiates the utility class.But how to pass the exception to my utility class and catch it again there and generate more user friendly messages??

Answer 1

My utility class contains catch blocks for all types
of exceptions.I want to catch the exact exception and
create user friendly messages there only.If I pass
exception object from the controller to the utility
class how to make it's catch blocks catch the passed
exception??I understood what you said, but that's not how you usually do it, but you can if you want:
// Code from some method
        try {
            throw new IOException("Test");
        } catch (Exception e) {
            Utility.handleExeption(e);
// The utility class
class Utility {
    public static void handleExeption(Throwable t) {
        try {
            throw t;
        } catch (IOException ex) {
            System.err.println("IOException " + ex);
        } catch (Throwable ex) {
            System.err.println("Throwable " + ex);
}Note that you probably don't want to catch throwables. It was just to show that it can be done.
