RE: Use JSPC
Ok, I tried the simple hello world jsp, with the same result.
Adding the path to my jars and/or classes lead to the same issue.
I also removed my tomcat 5.5.9 installed from windows installer to use the the
zipped archived (it contain a jspc.bat script) without success.
Another try was to use ant from command line, with the same result.
I cant figure out what I'm missing as I'm not so experimented in j2ee.
Anyway I'm still trying to make jspc work...

What I think is missing is the Webapplication classes in your classpath, so:
fileset dir=${webapp.path}/lib
include name=*.jar/
/fileset
fileset dir=${webapp.path}/classes
include name=**/*.class/
/fileset
But I didn't test this on my System.
But narrow it down I would do the following:
Just write a simple Hello world jsp and remove all other Jsps from your
application.
Try to get jasper working with this file, if it's working fine, then you
know an application specfic calls is not picked up.
If the Hello world jsp does not work, you know it's a Tomcat/JRE class
which is missing.

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.
Good luck!
Bernhard

Hi bernhard,
Just a few dumb questions on this, I still have problem to
generate servlets source files from jsp.
From a previous message you sent on this subject in another
thread I guess I have a classpath problem in my jspc task (
NullPointerException at
org.apache.jasper.JspCompilationContext.createCompiler(JspComp
ilationContext.java:220) with tomcat 5.5.9).
I think I have the correct values for getting tools.jar and
jasper jars in jspc.classpath.
So, should the webapp be placed in tomcat webapps directory
in order to allow jspc work ? or maybe it doesn't matter ?
Maybe someone have an idea on what I miss...

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.

If you have the generated java files, you can compile

RE: Use JSPC
Assuming an configuration problem on my PC to be the cause of my problem, I
did successively:
- desinstall tomcat 5.5.9 (there was one to test the web app)
- 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
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jasper-howto.html
target name=jspc
taskdef classname=org.apache.jasper.JspC name=jasper2
classpath id=jspc.classpath

validateXml=false
uriroot=${webapp.path}

outputDir=${webapp.path}/WEB-INF/src /
/target
First attempt, it still throw a NullPointerException (
java.lang.NullPointerException at
org.apache.jasper.JspCompilationContext.createCompiler(JspCompilationContext.java:220
) but I remarked a problem.
The ant task assume that the presence of tools.jar at:
pathelement location=${java.home}/../lib/tools.jar/
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 :
+build
+WEB-INF
+classes
my_classes_files
+lib
my_libs
+src
my_source_files
web.xml
+META-INF
context.xml
+some_jsp_directories
index.jsp
error.jsp
so I arrived to a conclusion: it seems that I have 2 left hands :o)

And remember to update your web.xml with the servlet and servlet mapping elements for the generated classes. It looks a bit daunting at first, but the examples on the Tomcat site will be a good help and once done, it it actually quite straigtforward.
