Packages and directories for generated .java and .class files
By default, the .java files for all JSPs 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.
If the JSP engine configuration parameter useFullPackageNames is set to true, the .java files are generated with the package statement
Package _ibmjsp.<directory structure in which the jsp is located>;The usage of full package names enables the configuration of a JSP as a servlet in web.xml. See JSP class loading settings for more information. The table below gives examples of packages and directory structures for generated .java and .class files.
