Compilation errors?
it looks like some packages weren't downloaded with everything else. Did you check to see if there is a package called javax.microedition.midlet in what you downloaded?
Reply:Check your classpath and path environment variables.


Your CLASSPATH env. var should point to wherever your class tree starts.
Reply:If you try to evaluate an expression containing a compilation error, it will be reported in the scrapbook editor.





For example, type and select the (invalid) expression System.println("hi") in the editor and click Execute in the toolbar.





The error message The method println(java.lang.String) is undefined for the type java.lang.System appears in the editor at the point of the error.
