Re: force precompilation of JSPs
This reminds me of a script I have written. It deletes the work
directory for a given context and precompiles the JSPs. No need to fight
with JSPC :-)
I have attached it, simple but effective.

Subject: force precompilation of JSPs
Hi,
I am experiencing a slow down when I access a JSP page for the first
time after I deploy e web app.
Is there a way to force precompilation of these files as soon as the web
app is deployed ?
Thanks,
ionel

Re: force precompilation of JSPs
If you are using Tomcat. %TOMCAT_HOME%/bin/jspc can do this. read your Tomcat documentation for instructions. For other look at vendor specific documentation for clues. --Alen - Original Message - From: Ionel Gardais [EMAIL PROTECTED] To: Struts Users Mailing List [EMAIL PROTECTED] Sent: Tuesday, August 05, 2003 8:48 AM Subject: force precompilation of JSPs Hi, I am experiencing a slow down when I access a JSP page for the first time after I deploy e web app. Is there a way to force precompilation of these files as soon as the web app is deployed ?

RE: force precompilation of JSPs
I am using iPlanet where I use the following ant target to rebuild the
jsps
target name=compile.jsps depends=init,splash
description=Compile the jsp file for faster access
jspc
destdir=${webserver.cache.folder}
srcdir=${build.home}
compiler=jasper41
webapp basedir=${build.home}/
classpath refid=jspc.classpath/
include name=**/*.jsp/
/jspc
javac
srcdir=${webserver.cache.folder}
destdir=${webserver.cache.folder}
debug=${compile.debug}
optimize=${compile.optimize}
deprecation=${compile.deprecation}
classpath refid=jspc.classpath/
/javac
/target
or you can use this to do for each one
exec executable=jspc.cmd
arg line=${webserver.jspengine.jar} ${webserver.cache.folder}
${compile.jsp.file}/
/exec
javac
srcdir=${webserver.cache.folder}
destdir=${webserver.cache.folder}
debug=${compile.debug}
optimize=${compile.optimize}
deprecation=${compile.deprecation}
classpath refid=jspc.classpath/
/javac
jspc.bat
@echo off
java -classpath jar files org.apache.jasper.JspC -d %2 -v0 -die9 %3
jspengine.jar should be in classpath
best regards
Thiru
