java.net.ServerSocket is a restricted class

I am using SmartGWT 2.3.0 verion on Indigo and GAE as 1.5.2
When I started the app using run configuration of Eclipse for the sample project builtinds, I get the following error.

[Server@1c5822c]: [Thread[main,5,main]]: checkRunning(false) entered

Let me know if someone has a solution for this

The builtinds project uses SQLDataSource which cannot be used on GAE since there is no SQL support. You need to use the GAEJPADataSource and the GAE sample project. However, we are now recommending Amazon Elastic Beanstalk instead - it's just as a simple and has no such limitations.
