You can have following type of errors in your JSP code: Checked exceptions: Achecked exception is an exception that is typically a user error or a problem that cannot be foreseen by the programmer. For example, if a file is to be opened, but the file cannot be found, an exception occurs. These exceptions cannot simply be ignored at the time of compilation. Runtime exceptions: A runtime exception is an exception that occurs that probably could have been avoided by the programmer. As opposed to checked exceptions, runtime exceptions are ignored at the time of compliation. Errors: These are not exceptions at all, but problems that arise beyond the control of the user or the programmer.

I have an ext form that I am submitting to my server. Due to a bug in my server code, an exception is being thrown and my web server's Error 500 page is being returned. The problem with this is my ext form is expecting a JSON response, but the Error 500 page is HTML, thus causing Ext to fail being unable to parse the '<' character. How can I handle this situation? I want to display a message to the user that an error occurred, but this Ext exception is causing my failure handler not being call, as well as the form's waitMsg to not go away.
