-help
Enables quiet mode (same as?-v0). Only fatal error messages are displayed.
-v?
Verbose mode.?
-d?dir
Specifies the output directory for the compiled JSPs. Package directories are automatically generated based on the directories containing the uncompiled JSPs. The default top-level directory is the directory from which?jspc?is invoked.
-l
Specifies the name of the JSP on failure.?
-s
Specifies the name of the JSP on success.?
-p?name
Specifies the name of the target package for all specified JSPs,overriding the default package generation performed by the?-d?option.
-c?name
Specifies the target class name of the first JSP compiled. Subsequent JSPs are unaffected.?
-mapped
Generates separate?write()?calls for each HTML line in the JSP.
die(#)
Generates an error return code (#) on fatal errors (default 1).?
-uribase?dir
Specifies the URI directory to which compilations are relative. Applies only to explicitly declared JSP files.?
This path is the location of each JSP file relative to the?uriroot. If this location cannot be determined,the default is?/.
-uriroot?dir
A directory containing a web application. All JSPs in the directory and its subdirectories are compiled. You cannot specify a WAR,or ZIP file. You must first extract such files to an open directory structure.?
-compile
Compiles the generated servlets.?
-genclass
Generates class files in addition to Java files.?
-webinc?file
Creates a partial servlet mappings in the file.?
-web.xml?file
Creates a complete?web.xml?structure in the file.
-ieplugin?clsid
Java Plug-in?classid?for Internet Explorer.
classpath?path
Overrides the?java.class.path?system property
xpoweredBy
Add the X-Powered-By response header.?
-trimSpaces
Trims spaces in text templates between actions and directives.?
-smap
Generates SMAP info for JSR 45 debugging.?
-dumpsmap
Dumps SMAP info for JSR45 debugging into a file.?
-compilerSourceVMrelease
Provides source compatibility with specified JDKTM?release.
-compilerTargetVMrelease
Generates class files for specified VM version.?
For example,this command compiles the?hello?JSP file and writes the compiled JSP under?hellodir:
jspc -d hellodir -genclass hello.jsp
This command compiles all of the JSP files in the web application under?webappdir?into class files under?jspclassdir:
jspc -d jspclassdir -genclass -webapp webappdir
To use either of these precompiled JSPs in a web application,put the classes under?hellodir?or?jspclassdir?into a JAR file,place the JAR file under?WEB-INF/lib,and set the?reload-interval?property to?-1?in the?sun-web.xml?file.
When a JSP is compiled,a package is created for it. The?package name starts with?jspc. For example,the generated package name for~/SOURCE/JSP/myjsps/hello.jsp?is precompiled as?jspc -webapp ~/SOURCE -d ~/test1/test2/test3. The generated servlet is located in?~/test1/test2/test3/org/apache/jsp/JSP/myjsps/hello_jsp.java?and defined in?org.apache.jsp.JSP.myjsps. The path for?hello.jsp?is derived from the directory in which the JSP is located.
In another example,the same?hello.jsp?is precompiled using the?—p?option,and is precompiled as?jspc -webapp ~/SOURCE -d ~/test1/test2/test3 -p app1.app2.app3. The generated servlet is located in~/test1/test2/test3/app1/app2/app3/JSP/myjsps/hello_jsp.java?and defined inside package?app1.app2.app3.JSP.myjsps. Note that the package specified with the?-p?option (app1.app2.app3) overrides the standard?org.apache.jsp?but does not affect the package derived from the directory in which the JSP is located. Also,note that the?-d?option does not affect on the generated package name.
For information about the various JSP configuration parameters you can use,see the section?jsp-config?Element. The JSP compiler uses the default values for parameters that are not included in the file.
