java.lang.object error - the problem is solved

pacossOct 6 2005 — edited Feb 25 2009
i have installed jdeveloper 10 (unzip jdev10.exe, run jdevw.exe) and tried to create my first program following the tutorial, but...
i created workspace (workspace1), then added a new project (project1), and then tried to create a simple file-java class, the dialog box opened in which i should've chosen name (class1), package (mypackage1) and extends (java.lang.object) and also checked all three choices (public, constructor, main method). after i clicked ok an error is thrown:
'java.lang.Object is not a valid base class for this operation'. so, what's wrong?
