Hi,

In chapter 7 there is an example of a Java-Application "BookApp". When I compiled the code, and wanted to run it I got the error :

"Exception in thread "main" java.lang.NoClassDefFoundError : BookApp

My code looks like :

public class BookApp{

    private String title;

    public String getTitle(){
        return title;
    }

    public void setTitle(String title){
        this.title = title;
    }

    public static void main (String[] args){
        BookApp myBook = new BookApp();
        myBook.setTitle("Beginning JSP Web-Development");
        System.out.println(myBook.getTitle());
    }
}

Java-code and compiled class are in the directory \com\wrox\library.

this seems to be a classpath problem. Check your classpath and make sure it is setup properly.
