I set up a bean with an id of “exceptionResolver” made it an instance of org.springframework.web.servlet.handler.SimpleMappingExceptionResolver. Then I define two properties, “defaultErrorView” and “exceptionMappings”.
As I understand it this should catch any exceptions thrown in my web application and forward to the view I’ve specified.
This is not happening, all I get is the standard tomcat 500 error page with stack trace. what am I doing wrong? Additionally, I’m using spring 2.5.5 and all of my controllers/dao/etc… are defined using spring annotations.
Here’s a spit out of my stack trace.
