Exception Trap

Configure it in your WEB-INF/web.xml like this:

<servlet>
  <servlet-name>ExceptionTrap</servlet-name>
  <servlet-class>com.rexsl.core.ExceptionTrap</servlet-class>
  <init-param>
    <param-name>template</param-name>
    <param-value>/com/foo/exception.html</param-value>
  </init-param>
</servlet>
<servlet-mapping>
  <servlet-name>ExceptionTrap</servlet-name>
  <url-pattern>/trap</url-pattern>
</servlet-mapping>
<error-page>
  <exception-type>java.lang.Throwable</exception-type>
  <location>/trap</location>
</error-page>

Every exception will be caught by this servlet and rendered as "service not available" HTML pages. Read javadoc for more information.
