EJBs are built for more than just a Java EE application server. They can also execute in aJava EE Web Profile container or plain Java SE environment (Java SE ! yeah – Easy JavaBeans !).
Here in this post we will learn how to handle Exception in jsp page using JSTL tags
Here is the sample code for this app…
index.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<body>
<strong>Exception Handling Example</strong><br>
<a href="<c:url value='Check.jsp' />" >Go to Exception Page</a><br>
<br>
<%-- The above line is similar to response.encodeURL("url") method of servlet --%>
</body>
</html>
when we click on Go to Exception Page it will send u too Check.jsp page contain the following code:
check.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<body>
<strong>Exception Handling Example</strong>
<br>
<c:catch var=”myexception” ><%—This is similar to try { }catch{} of normal exception handling –-%>
<strong>Inside the Catch Block : >></strong>
<br>
<br>
<% int x = 10/0; %>
</c:catch>
<%– the <c:chosoe> , c:when and c:otherwise is equivalant to if {}else {} statement !! thanx –%>
<c:choose>
<c:when test=”${myexception != null}” >
There was an Exception : ${myexception.message}<br><br>
</c:when>
<c:otherwise >
No Problem thanks!!
</c:otherwise >
</c:choose>
</body>
</html>

at int x=10/0; there is devide by zero exception which is catch by the above given block
