How do I use GenericFilterBean to require filter properties

[scott69taylor]

I'm try to use GenericFilterBean to set a required property in my ServletFilter. The problem is I'm not sure where I'm suppose to call the addRequiredProperty() method. In my subclasses constructor?

In my example, I have servlet filter that specifies a param name of "urlPrefix" in the web.xml. My filter extends GenericFilterBean and I've added a setUrlPrefix(String) method. In the constructor I have:

{
 super();
 addRequiredProperty("urlPrefix");
}

But when I deploy my web application I get an error message. If I remove the addRequiredProperty, my filter starts okay, but the setUrlPrefix isn't called.

What am I doing wrong?
