I'm playing around with trying to use the JDeveloper editor to write PL/SQL
code that I'd like to put into either a package or library for use with my
Oracle Forms.

In a properties setting I was able to add all the available Oracle libraries
as selected libraries. I specifically added Oracle Forms and Oracle9 iAS
libraries.

Yet when I try to compile a section of code like this:

v_Height := Get_Window_Property('WINDOW0',HEIGHT);
v_Width := Get_Window_Property('WINDOW0',WIDTH);

Set_Window_Property(FORMS_MDI_WINDOW,HEIGHT,v_Heig ht);
Set_Window_Property(FORMS_MDI_WINDOW,WIDTH,v_Width );
Set_Window_Property(FORMS_MDI_WINDOW,TITLE,System_ Name);

I'll get an error messages of:

GET_WINDOW_PROPERTY must be declared and FORMS_MDI_WINDOW must be
declared.

I had thought that since I was including the two Oracle libraries that
they'd be declared.

Do I have to specifically add what Oracle forms package the statements come
from or what? I created this code from within Oracle Forms where it did
compile and work so I know it has to be something my lack of experience
isn't picking up.

Thanks in advance.
