<% } else { String url = response.encodeRedirectURL("index.jsp"); response.sendRedirect(url); } %> Having to break the <% ... %> block to use the jsp:forward is ugly and makes it harder to read due to indentation, among other things. So, can I do the forward in the Java code without use the JSP tag? Something like this would be ideal: <% String errorMessage = SomeClass.getInstance().doSomething(); if (errorMessage != null) { session.setAttribute("error", errorMessage); someObject.forward("error.jsp"); } else { String url = response.encodeRedirectURL("index.jsp"); response.sendRedirect(url); } %> java jsp jsp-tags forward share|improve this question asked Oct 28 '08 at 23:15 Chris Carruthers 2,10952130 It's the breaking up of code that makes scriptlets unmaintainable over time. That's why the push was made to use tag libraries and JSTL in the first place. It's easier to see it all as akin to HTML than <% for // %> some text <% do something %> other text <% end for loop %> more text. –MetroidFan2002 Oct 29 '08 at 6:29 add a comment| 3 Answers 3 active oldest votes up vote 28 down vote accepted The someObject you are looking
either inside the page or outside the page (such as in a called JavaBean). This section describes the JSP error processing mechanism and provides a simple example. Using JSP Error Pages Any web.xml error-page exception-type runtime error encountered during execution of a JSP page is handled using error.jsp example the standard Java exception mechanism in one of two ways: You can catch and handle exceptions in a Java

scriptlet within the JSP page itself, using standard Java exception-handling code. Exceptions you do not catch in the JSP page will result in forwarding of the request and uncaught exception to http://stackoverflow.com/questions/245236/jspforward-in-java-without-using-jsp-tag an error page. This is the preferred way to handle JSP errors. You can specify the URL of an error page by setting the errorPage parameter in a page directive in the originating JSP page. (For an overview of JSP directives, including the page directive, see "Directives". ) In a servlet 2.2 environment, you can also specify a default error page in http://docs.oracle.com/cd/A87860_01/doc/java.817/a83726/basics6.htm the web.xml deployment descriptor with instructions such as the following:

Author: Deron Eriksson Description: This Java tutorial describes how to create a JSP error page to handle exceptions. Tutorial created using: Windows XP || JDK 1.5.0_09 || Eclipse Web Tools Platform 2.0 (Eclipse 3.3.0) || Tomcat 5.5.20 Page: 1 2> When an exception is thrown in your web application and it is not caught, you will typically see the result featuring the exception displayed in your browser window, as shown here: Rather than displaying the above default page when an exception occurs, you can redirect the user to a custom-written error page for a particular type of exception. You can do this via the error-page element in web.xmlW, in which you can specify an exception-type and the location of the resource where a user should be sent if an error occurs. In this example, I specified the exception-type as java.lang.Throwable so that all exceptions would be sent to the error.jsp page.
