Project Facet Java 6.0 not supported

I just watched a webinar about how to use POJOs with the eclipse plugins,

I downloaded the eclipse plugin and tried to reproduce the steps outlined in the video.

I created my jsp then tried to run it on the server but when trying to configure a server to run it on it said

'Project Facet Java version 6.0 not supported.'

What do I need to do to get it working?
