Adding All Subfolders of a Folder to the Classpath

Is there a way to specify a folder and have all the class files in that folder's subfolders loaded?

I don't understand the question. If I add the folder /java/classes/ to the classpath then everything under there is on the classpath. If you had /java/classes/my/package/A.class and looked for my.package.A you'd find it. If you just looked for A then you wouldn't. What am I not understanding?

sorry. youre right about packages (like in jars).

what if you arent using packages?

root

root/1/a.class

root/1/b.class

root/2/c.class

root/2/d.class

root/3/e.class

root/3/f.class

instead of doing

java -cp root;root/1;root/2;root/3 Program

is there a

java -cp (everything in root) Program

eh. its not a big deal. im just prototyping this idea (a home project) and whipping something up that will be in flux for a while.

anyway, itll require a bunch of folders (the number of which will change a lot). so instead of jarring the project every night or having some obnoxious list of classpaths i was hoping there was a lazy option ; )

java -cp (oh hell just grab everything) Program

Well if you need alazy option. You can write a program to traverse through the folder structure and generate a batch script which set the class path and execute your classAnd then you can execute that batch script using the Runtime.exec

Haha, not a totally bad idea actually.But if i went that route couldnt I just use a URLClassloader to load the classes directly rather than create the BAT and all that.

Yes you could. Why do you want to add the classes to the classpath? What's the design? Is it a plugin type of thing?

I think it will be hard to implement if you allow several "roots" at different depths. How will you know if a folder is a root, or part of a package name?
