Compilation problems exampleServerSync.java

[perqa]

I am not a Java programmer, but I'm trying to compile exampleServerSync.java to get started using the WebSqlSync framework. The error log is attached below. I wonder about the two dependencies utils and models:
import utils.;
import models.;
As far as I understand, they are not standard Java libraries. I get an error message regarding utils, but not regarding models. I have added the jamon and gson jars to the lib/ directory.

Yes of course, it will not compile like that. It's just an example to read (not to run), a lot of dependency are missing.
