I've got the same problem as you today, And no answer from the web can solve it. However, I fixed it at last.

In fact, there is nothing wrong with the setup, it is right to import those jars through "Add External JARs". The real problem is the location/package of you java code. I found that you have to put your .java file in the default package. For example, you will get errors if you put your java code in a package like com.xxx.yyy.ccc, below is an image which shows the right location/package you should use(see WTF.java). After doing that, you program will be able to run.

However, that is how i fixed my problem, i'm not sure that could work for everyone..
