How to create a common error page using JSP?
JSP gives you an option to specify Error Page for each JSP using page attribute. Whenever the page throws an exception, the JSP container automatically invokes the error page.
Following is an example to specifiy an error page for a main.jsp. To set up an error page, use the directive.
<%@ page errorPage = "ShowError.jsp" %>
<html>
<head>
<title>Error Handling Example</title>
</head>
<body>
<%
// Throw an exception to invoke the error page
int x = 1;
if (x == 1) {
throw new RuntimeException("Error condition!!!");
}
%>
</body>
</html>
We will now write one Error Handling JSP ShowError.jsp, which is given below. Notice that the error-handling page includes the directive . This directive causes the JSP compiler to generate the exception instance variable.
<%@ page isErrorPage = "true" %>
<html>
<head>
<title>Show Error Page</title>
</head>
<body>
<h1>Opps...</h1>
<p>Sorry, an error occurred.</p>
<p>Here is the exception stack trace: </p>
<pre><% exception.printStackTrace(response.getWriter()); %>
