RE: Pre-compiled JSPs?
Hi,
You need to insert in your web.xml the reference to the precompiled
servlets. Jasper can generate a web.xml fragment when turning JSP into
servlets. You can then insert the fragment into your web.xml
Something like this with ant:
!-- turn jsp into servlets --
jasper2 verbose=0
package=your.package
validateXml=false
uriroot=${webapp.path}
webXmlFragment=generated-web.xml
outputDir=${webapp.path}/WEB-INF/src /
!-- Load the precompiled snippet into a property --
loadfile property=precompiled
srcFile= generated-web.xml
encoding=ISO-8859-1 /
!-- Now replace the web.xml with a predefined snippet --
!-- copy web.xml --
replace file=web.xml value=${precompiled}
replacetokenlt;!-- jsp-servlets will be inserted here - do not remove
this line --gt;/replacetoken

Subject: Pre-compiled JSPs?
Hi everyone,
I have a fairly elaborate problem but hope that some people out there
can help with it.
I am trying to take a large webapp and create pre-compiled JSPs. We
already compile the java into class files, then package in JARs, then
finally a WAR, but we would like to be able to package the JSPs into a
neat package, too.
The first hurdle was trying to circumvent the issue of when JSPs include
each other and a bean is used in both JSPs but can only be declared once
when the JSPs are combined. Thus, you have to leave out the bean
declaration in the second JSP but then it will not compile on it's own
because it has no knowledge of the bean. Fortunately, in the recent
Tomcat releases, it's possible to use the flag
'errorOnUseBeanInvalidClassAttribute' to ignore this problem.
Once the JSPs have been turned into Java classes by Jasper2, it's not
too hard to compile them into class files. But how do you deploy these
compiled classes so that Tomcat knows to use them? If the Whatever.jsp
file doesn't exist, how does Tomcat know where or how to find the
compiled JSP file? Should I put them in a JAR and deploy somewhere? Do I
need to change the web.xml or similar to inform Tomcat about this?
If anyone has any suggestions, advice or solutions to this, I would be
eternally grateful! :)
Thanks,
Richard.

Hi Nicolas,
what jspc basically needs, is acces to all the internal
tomcat libraries,
as you see from the ant script:
${tomcat.home}/bin/*.jar
${tomcat.home}/server/lib/*.jar
${tomcat.home}/common/lib/*.jar
As well as all the libraries from you web application.
So what I did was just installing (unzipping) Tomcat on my
deployment
machine, just in order to the able to do the precomplation. I
think you can
also just download the deployer distribution
(http://jakarta.apache.org/site/downloads/downloads_tomcat-5.cgi) this
should contain all the stuff you need for the deployment. But
I don't have
experience with the deployer application.
Conerning you web application: You need to include all the classes and
libraries in the classpath as well, but it doesn't have to be under
${tomcat.home}/webapps it can be anywhere on your deployment machine.
Maybe what's missing is that you have to include the /WEB-INF/classes
directory too in your ant script.
It's not in mine because I only use jar files in my webapp.

RE: Use JSPC
Hurrey! I finally succeed to solve my problem. The way is not very orthodox but
at least jsp are turned into servlets.
So I removed the classpath/classpath from the jasper taskdef markup and
added the needed jars at hand into eclipse ant configuration.
For the one interested the concerned jars are :
- commons-logging-api.jar
- commons-el.jar
- jasper-compiler.jar
- jasper-runtime.jar
- tools.jar from jdk
Moreover I included the folder of my class files.
It seems that the troubles came from the addition of classpath markup in jasper
taskdef. Maybe a conflict with a previously added jars in ant classpath as I've
seen lot of people using jspc without problem.

- desinstall jdk 1.5.0_03 and an anterior jdk 1.4
- install jdk 1.5.0_03, with standard directories option
- install tomcat
After that I did a copy/paste in my build.xml of the jspc task found at

The ant task assume that the presence of tools.jar at:

But the jdk 1.5 on windows install the following directories :
C:
+Program Files
+Java
+jdk1.5.0_03
+jre1.5.0_03
and make point ${java.home} to c:/Program Files/Java/jre1.5.0_03 and so cannot
find tools.jar at ${java.home}/../lib/tools.jar
ok, no problem. As I didn't want to modify the copy/pasted task from
jasper-howto, I decided to use the jre shipped with jdk at c:/Program
Files/Java/jdk1.5.0_03/jre.
So I removed the jre from system, added the registry key for 1.5 - removed
during jre desinstall - that point to the correct JavaHome, RuntimeLib and try
again with a corrected ${java.home}.
Unfortunately this second attempt failed too. NullPointerException is back .
Aargh.
For information, I set ${tomcat.home} to C:/Program Files/Apache Software
Foundation/Tomcat 5.5 and the webapp.path is set to the directory
c:/eclipse/workspace/myWebApp/build which has the following structure :

When I launch the task, I got the following error on a jsp file:
org.apache.jasper.JasperException:
file:C:/eclipse/workspace/MyWebApp/web/jsp/login/index.jsp(18,0) The
value for the useBean class attribute myapp.jspbean.IndexJspBean is
invalid.
The error in the index.jsp file come from the line:
jsp:useBean id=indexJspBean scope=session class=
myapp.jspbean.IndexJspBean /
As I thought that I should give to jspC a reference to the Bean, I tried
to package the Bean in a jar file, put it in library directory and then
uncommenting the reference to the libray directory in the previous ant
file sample, but I got then the following error:

BUILD FAILED: C:\eclipse\workspace\MywebApp\build.xml:158:
org.apache.jasper.JasperException
I'm using the task shipped with tomcat 5.5.4.
Have anyone an idea about what I'm missing ?
