In JSP, you can use JSTL tag

<c:catch var="exceptionObject">

</c:catch>

This tag will catch the exception and will assign the implicit exception object to the var defined as attribute above. Then you can use this var to get message or more information about the exception. This var will be object of Throwable which is superclass in Exception hierarchy.

When ever Exception accoured redirect the cantrol to the Error page
<%@ page ErrorPage="error.jsp" %>

In Error page add the bellow line of code
<%@ page isErrorPage="true" %>
<%
out.println(" ");
PrintWriter pw=request.getWriter();
Exception.getPrintStakeTrace(pw);
out.println(" ");
%>

Example:

The exception will be thrown inside the catch:

<% int x = 5/0;%>

The exception is : ${catchException}

There is an exception: ${catchException.message}
