Please explain the directory structure required to execute a jsp program? I have package named package1 . This contains a class named class1. I created directory as folder "Webroot" The Webroot folder contains 2 subfolders named "WEB-INF" and "src" and 2 jsp pages. The src folder contains a subfolder named "package1".This package1 contains the file "class1.java". WEB-INF contains further 2 subfolders named "classes" and "lib" and a "web.xml" page. The "classes" folder contains further a subfolder "package1"."package1" further contains "class1.class" file. The program does not execute. Please tell where is the mistake??
