JSP exception object

JSP exception implicit object is instance of java.lang.Throwable class .

It is used for exception handling in JSP. But it can only be used in error pages, which means a JSP page should have isErrorPage to true in order to use exception implicit object.

Example of exception implicit object:

index.html

<html>

<body>

<form action="first.jsp"> 
Enter First No:<input type="text" name="firstnum" />

Enter Second No:<input type="text" name="secondnum" /> 

<input type="submit" value="Get Results"/> 

</form>

</body>

</html>

first.jsp

<%@ page errorPage="error.jsp" %> 
<% 

String n1=request.getParameter("firstnum"); 

String n2=request.getParameter("secondnum"); 

int n1= Integer.parseInt(n1);

int n2= Integer.parseInt(n2);

int r= v1/v2;

out.print("Output is: "+ r);

%>

error.jsp

<%@ page isErrorPage="true" %> 

<%= exception %>
