The JSP Command-Line Compiler

Chapter 4 Using JavaServer Pages 43

The cache has a Version file containing a version number that the server uses to

determine the structure of the directories and files in the caches. You can clean out

the caches by simply deleting the version file.

When the server starts up, if it does not find the version file, it deletes the directory

structures for the corresponding caches and re-creates the version file. Next time

the server serves a JSP page, it recreates the JSP class cache.

You can delete the version file simply by deleting it from the

ClassCache directory

as you would normally delete a file, or you can use the Java>Delete Version Files

page in the Server Manager to delete it. After deleting one or both version files, be

sure to restart the iPlanet Web Server to force it to clean up the appropriate caches

and to recreate the version file before the server serves any JSPs.

The JSP Command-Line Compiler

You can precompile JSPs for faster performance; this is recommended for

production servers. A command-line JSP compiler is included with iPlanet Web

Server. The JSP compiler is located under server_root

/bin/https/bin (make sure

this directory is in your path). The

IWS_SERVER_HOME environment variable must

be set to the server_root directory.

The format of the

jspc command is as follows:

jspc [options] jsp_files

The jsp_files can be one of the following:

The

options for the jspc command are:

files One or more JSP files to be compiled.

-webapp dir A directory containing a web application. All JSPs in the

directory and its subdirectories are compiled. You cannot

specify a WAR, JAR, or ZIP file.

-q Enables quiet mode (same as -v0). Only fatal error messages

are displayed.
