custom 503 error page thrown from servlet java

This is pretty simple and straightforward. I want to throw a 503 error from the servlet side.
response.sendError(503);
When this is thrown, I need it to hit a custom error page. Basically a 503 error page itself, but with a few modifications.
Say I have 503.html
, and I added
<error-page>
<error-code>503</error-code>
<location>/503.html</location>
</error-page>
in web.xml
.
I created a war file, with a servlet which throws the 503 error, and web.xml
with this content. I kept the 503.html
in the parent folder location. (Should I keep it elsewhere ?)
I deployed the app in WLS, but this custom 503.html
is not getting hit. I am getting the generic 503 error.
Am I missing something?
My code is below:
webapp1.war
->web-inf
->web-inf->classes->prject4->Class1.class
->web-inf->jsp->error->custom.html
web.xml
<?xml version="1.0"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>
<servlet>
<servlet-name>Class1</servlet-name>
<servlet-class>project2.Class1</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>Class1</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<error-page>
<error-code>503</error-code>
<location>/WEB-INF/jsp/error/custom.html</location>
</error-page>
</web-app>
class1.java
public class Class1 extends HttpServlet
{
private ServletConfig config;
public void init(ServletConfig config)throws ServletException
{
this.config=config;
}
public void service (HttpServletRequest request, HttpServletResponse response)
throws IOException
{
response.setContentType("text/html");
ServletOutputStream l_out = response.getOutputStream();
response.sendError(503);
}
}
