Developing JSP files

Learn about JSP files.

JSP class file generation
At runtime, the WebSphere® Application Server JavaServer Pages (JSP) engine loads JSP class files from either the WebSphere Application Server temp directory or a web module's WEB-INF/classes directory. The JSP engine first searches for a class file in the temp directory and then it searches in the web module's WEB-INF/classes directory.
Web container configuration for JavaServer Pages static file access
Packages and directories for generated .java and .class files
By default, the .java files for all JavaServer Pages (JSP) files are generated with the package statement, package com.ibm._jsp;. The JSP engine's class loader knows how to load JSP classes when they are all in the same package. The .java files are located in the filesystem within a directory structure mirroring the JSP source directory structure.
JSP batch compilation
As an IBM® enhancement to JavaServer Pages (JSP) support, IBM WebSphere Application Server provides a batch JSP compiler that allows JSP page compilation before application deployment. The batch compiler validates the syntax of JSP pages, translates the JSP pages into Java™ source files, and compiles the Java source files into Java servlet class files. The batch compiler also validates tag files and generates their Java implementation classes.
Global tag libraries (deprecated)
JavaServer Pages (JSP) tag libraries contain classes for common tasks such as processing forms and accessing databases from JSP files.
