When we look at the directory structure of JBoss AS, we see that the modules are present under the "modules" folder.

When we navigate further in the directory, we see couple of modules under the parent directory and some other modules under "org" directory.

Is there any specific reasons for placing the modules under different directories.

For example, com/sun/httpserver module is under modules/org/jboss, and we have com/sun/xml under "modules" directory.

why is it that the httpserver modules placed under org/jboss.

Similarly there are other modules as well.
