Here's one of the JSP example files that come with Polystyle. Polystyle comes with style files for: Allman/BSD, Ellemtel, GNU, Kernighan & Ritchie, One True Brace Style, Unix Kernel, Linux Kernel, Stroustrup, Sun Microsystems, and Whitesmith. Each example file come in various indent styles, such as 2-space, 1-tab, 4-space, and others. Your style is easily configured using the Configuration Tool. To define your style, you simply edit an example file however you like.

 * This is a recommended Polystyle JSP example.
 * Reformat this file as you like to define your personal style.
 *
 * Notes:
 * 1.) Formatting information for inline <jsp:directive> tags are defined
 *     in example.html.
 *
 * 2.) Polystyle does not format comments based on examples. It will always
 *     format comments the same way.
