New to Java

Hello, I have just installed Eclipse 3.3 on Ubuntu. When I click on File...New...Java Project, and name my project, the project appears on the left with a small red box indicating an error. The two errors indicated are:

"The project cannot be built until build path errors are resolved"
"Unbound classpath container: "Default System Library in project "Test""

When I right click on the project and on properties, there is another error:

"Build path entry is missing: org.eclipse.jdt.launching.JRE_CONTAINER"

I tried to click on "Properties..."add library", and add the JRE system library, but when I click next the window does not move to the next screen. Anyone know how I can create a new project without these errors. Thanks.
