I've never used JBuilder 4.0 Professional and have run into an annoying problem.  To test the IDE I create two Classes an object
and a class to call the object.  Worked great.  Then I create another class within the same project (it displayed my name) ran
it and decided to delete it.  After deleting it from the project I ran the project again and I get the error:

\bin\javaw -classpath "C:\Documents and Settings\Mike Parish\jbproject\Chapter5\output;C:\JBuilder4\jdk1.3\demo\jfc\Java2D\Java2Demo.jar;C:\JBuilder4\jdk1.3\jre\lib\i18n.jar;C:\JBuilder4\jdk1.3\jre\lib\jaws.jar;C:\JBuilder4\jdk1.3\jre\lib\rt.jar;C:\JBuilder4\jdk1.3\jre\lib\sunrsasign.jar;C:\JBuilder4\jdk1.3\lib\dt.jar;C:\JBuilder4\jdk1.3\lib\tools.jar"  chapter5.HelloMike 
java.lang.NoClassDefFoundError: chapter5/HelloMike

Exception in thread "main" 

CLASS HelloMike does not exist!  How do I remove a class from the project without this problem repeating it's self?  Have I 
configured JBuilder incorrectly.  I'm running on Window 2000.
