When I compile my applets, I can import my own classes from other
subdirectories as long is my CLASSPATH is set correctly. But my applets will
not run from a client machine because my imported classes are not found at
runtime.
Must these custom classes that I import be in the same directory as, or a
subdirectory of my applet?
If so, then what about class reusability? Must I copy a custom class to
every subdirectory where an applet uses it? This would certainly make things
tough when making changes to a class because I'd have to make sure I
re-copied the changed class to all other subdirectories which need it. The
original Java classes are certainly reusable. All I ask is to be able to do
the same thing with my classes.
Let me ask this ... What have you done with custom classes? For example, if
you were to do what I'm doing -- subclassing the Canvas class, to create a
TextBoard class which displays scrollable text, then where would you place
this TextBoard class so that it could be re-used by any applets that wanted
to instantiate it? I don't mean where to place it for compilation purposes,
but where to place it so that it can be used at runtime when someone across
the internet connects to your server and runs the main applet.
Maybe even as a better question, I should ask how? -- how do I make the
applets find my custom classes at runtime? (I thought the CLASSPATH
environment variable was supposed to take care of this too, but obviously it
doesn't) I really don't want to make identical copies of a class for
different applets because this would defeat class reusability.
I've asked this question before. What I received was a response saying I
should use the codebase tag to try and take care of this problem. I haven't
been able to do that since my applet and imported classes are in separate
subdirectories. Now I'm looking for a straight answer, no guessing, no
beating around the bush ... Must my custom classes reside in the same
directory as the applet which calls them at runtime?
