Exception in using objectify in GAE

I am writing a GAE program which use objectify. I download objectify-4.0b1.jar form here and add modify WEB-INF/web.xml according to this. However, when I run my program, I got the following warnings. Another guy encoutered nearly the same problem as mine, but the solution may be different since I do use the latest jar file. It seems that com.googlecode.objectify.ObjectifyFilter can not be loaded. Anyone can tell me why?

I'm using the latest objectify with GAE 1.7.5 on eclipse.

Please copy the Objectify JAR file in the WEB-INF\lib folder of your project. This will make the Objectify classes available to the Web Container when it runs your application.
