I installed the complete IDE package and the RAP target. After that I wanted to try the "Hello world" example, as you can found here example, but I dont' have the class BasicEntryPoint, which is described in "Create the application UI". After "Launch the application" which is also explained in the example, I get the error:

What's wrong? I feel like the example description is wrong...

I'm also new to RAP and run into the same issue. And I agree with you, that this "Hello World" example is incomplete. The solution you can find here (you have to create this class manually (BasicEntryPoint)):

RAP Entry Point

Additionally you have to add the entry point to you configuration (plugin.xml):

   <extension
     point="org.eclipse.rap.ui.entrypoint">
  <entrypoint
        class="org.examples.rap.helloworld.BasicEntryPoint"
        id="entrypoint1"
        path="/rap">
  </entrypoint>
