# Standard App Server Directory Structure

A typical application server will be installed with a directory structure such as the following:

Within this structure only some of the subdirectories are of interest to a developer.

The `cobol` directory may still exist for some applications (for example, CCB), but that is now obsolete as all COBOL programs have been converted to Java for edge applications running on OUAF 4.5.0.x.

The `splapp` directory contains all the main application files, including the deployed custom jars (`cm.jar`) and Web server files (for example, JSP, Javascript).
