RE: jasper jsp precompilation error
This method was added in Servlet API version 2.3.
Can you check if you are using that version ?
Have a look at whats in your classpath at JSP precompilation time !!!

Subject: jasper jsp precompilation error
Hi
I am trying to do JSP precompilation as described at
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/jasper-howto.html. I can run
the application fine if I do not precompile, but when I do attempt to
precompile the JSP, I get the message:
BUILD FAILED

I am using Tomcat 5.0.30 Ant 1.6.2.
Does anyone have an idea what I should do? Below is my ant target XML.

AW: JSP Precompilation

JSP precompilation, jspc, NullPointerException
Hi,
I try to get the precompilation working with tomcat 5.5.7 under Windows NT.
I use the following target:
target name=jspc
taskdef classname=org.apache.jasper.JspC name=jasper2
classpath id=jspc.classpath

validateXml=false
uriroot=${webapp.path}
webXmlFragment=${webapp.path}/WEB-INF/generated_web.xml
outputDir=${webapp.path}/WEB-INF/src /

And I'm getting a NullPointer Exception (see below), looks like the Jasper

Anyone has a clue why this happens?
Thanks for your help

Sounds odd. For debugging - try using Mozilla (or Firefox). For Mozilla there is a utility for viewing the header sent and received. Firefox also has one called the webdeveloper toobar which can also do the same.

Coding In Paradise: Tomcat JSP Precompilation is SLOW!!
The entire JSP compilation process, using Ant and the jasper2 ant task, takes about 30 minutes! This is far too long.

Why not hit every URL with curl or wget before deploying and include Tomcat's work directory with your deployment? How does that compare for speed?

Given the definition of IncompatibleClassChangeError[1], it sounds like
you have a rogue JAR or classfile somewhere in the classpath. If you're

Check the various endorsed dirs, as people sometimes put JARs there

Also, this looks odd:

JSP Precompilation in Tomcat 5.0.26
Hello:
I am attempting to upgrade from Tomcat 4.0.6 to 5.0.26 (embedded in
JBoss 3.2.5). However, following the upgrade,
I can no longer seem to precompile my JSPs as I did before. The
following build.xml extract worked fine in 4.0.6:
jspc srcdir=${srcDir} destdir=${jspDir}
package=${pkgName} verbose=2
compilerclasspath=${env.CATALINA_HOME}/jasper-compiler.jar
include name=**/*.jsp /
classpath
pathelement
path=${env.CATALINA_HOME}/servlet-api.jar/
pathelement
path=${env.CATALINA_HOME}/commons-logging.jar/
pathelement
path=${env.CATALINA_HOME}/jasper-compiler.jar/
pathelement
path=${env.CATALINA_HOME}/jasper-runtime.jar/
pathelement
path=${env.XERCES_HOME}/xmlParserAPIs.jar/
pathelement path=${env.XERCES_HOME}/xercesImpl.jar/
pathelement path=${srcDir}/WEB-INF/lib/taglibs.jar/
/classpath
/jspc
Follwing the 5.0.26 upgrade, this now produces errors such as the
following:
[jasperc] org.apache.jasper.JasperException: Unrecognized option:
-v2.
Use -help for help.
I have also unsuccessfuly tried the apparently new, Tomcat 5
recommended
way of precompiling as follows:
taskdef classname=org.apache.jasper.JspC name=jasper2
classpath
pathelement path=${env.JAVA_HOME}/lib/tools.jar/
fileset dir=${env.CATALINA_HOME}
include name=*.jar/
/fileset
fileset dir=${env.CATALINA_HOME}/
include name=servlet*.jar/
/fileset
fileset dir=${env.CATALINA_HOME}/
include name=commons*.jar/
/fileset
pathelement path=${srcDir}/WEB-INF/lib/taglibs.jar/
/classpath
/taskdef
jasper2
validateXml=false
uriroot=${srcDir}
webXmlFramgment=${srcDir}/WEB-INF/generated_web.xml
outputDir=${jspDir}/
This produces the following error
java.lang.IncompatibleClassChangeError: Implementing class
What am I missing and/or not doing in the new version? What does
this error mean in this
context and how can I get more information about it (for example
what class is being changed
in an incompatible manner)? This is a stock Tomcat 5.0.26/JBoss
3.2.5 installation.
I'd appreciate any and all tips on what to investigate or how I
might track this down
and resolve it.
Thanks!

JSP Precompilation using Jasper

On using, EmptyStackException is thrown. Can anyone
provide me any suggestions ?

JSP Precompilation / JSPC / JSP servlet mapping
Hi, I've set my Tomcat 4.1.24 installation to production mode, i.e. I've set 'development' to false, 'reloading' to true and 'fork' to true in CATALINA_HOME/conf/web.xml. I have some JSPs that are modified from time to time. My questions are: 1a. Why is the package name for java files generated from a JSP compilation different when using JSPC and when you let Jasper compile the JSP when you access it (especially for JSP in directories in a context)? 1b. Can you use JSPC to precompile JSPs into the work directory without having to wait till they are accessed or using something like UNIX's wget to 'touch' the file and force a compilation? 2. How exactly does Jasper precompile JSPs into the work directory? Can one write an Ant build file to precompile JSPs in a context to the work dir the same way Jasper does? 3. If you've precompiled your JSPs and mapped them in web.xml would Jasper precompile them and reload them if they are subsequently modified? 4. What are the advantages of mapping JSPs in web.xml as opposed to having Jasper compile them in the work directory?

Re: JSP Precompilation / JSPC / JSP servlet mapping
Then, the declarations and mappings for the servlets which were generated
during the precompilation must be added to the web application deployment
descriptor. Insert the ${webapp.path}/WEB-INF/generated_web.xml at the right
place inside the ${webapp.path}/WEB-INF/web.xml file. Restart the web
application (using the manager) and test it to verify it is running fine
with precompiled servlets. An appropriate token placed in the web
application deployment descriptor may also be used to automatically insert
the generated servlet declarations and mappings using Ant filtering
capabilities. This is actually how all the webapps distributed with Tomcat
are automatically compiled as part of the build process.
This is the part that is very unclear. Please explain the use of the
webXmlFragment and how it can be used to place the mappings into a web.xml.

Please explain the use of the webXmlFragment and how it can be used to place the mappings into a web.xml. See Ant's Filter task documentation. Basically, you take your web.xml as you have it (without any of the precompiled jsp information) and add a token like @jspServletXml where you want the fragment placed at. Then define a filter in your build xml (using jspServletXml and webXmlFragment) and copy your existing web.xml to a new location (with filtering=true) -- this replaces @jspServletXml with jasper2's generated xml. Disclaimer: I don't use this method because the Ant tasks don't do what I need it to do (I need to support builds with precompile for multiple appservers). Instead, I manually enter all information for our precompiled jsps in the web.xml and use a different script for running jspc. justin Justin Ruthenbeck Software Engineer, NextEngine Inc. justinr - AT - nextengine DOT com Confidential See http://www.nextengine.com/confidentiality.php - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: JSP precompilation and including webinc.xml in web.xml

I got the complete precompilation process to work, but I gave up on trying to
reference the include file with an entity reference. It just doesn't work.
What I was able to do was write an XSLT stylesheet that takes the main
web.xml and the generated include file and generates a new web.xml that
incorporates both files. It uses the Ant style task to do the
transformation.
A slight wrinkle is that the generated include file is not a fully
well-formed XML file, in that it doesn't have a root element. So, in order
for the XML parser (used by Ant) to grok it, I had to write a simple
well-formed wrapper that references the include file with an entity reference.
It's ironic that I'm using the same mechanism in this process that I gave up
with using inside of Tomcat.
I'll show all the pieces of my solution here.
This is the excerpt from my build-war Ant target related to this:

Following this is the includeWrapper.xml file, which references the generated
include file. Note that I have to reference a path of web-inf/webinc.xml,
which is the path to the generated file in my build tree (not my deploy tree).
I'm using Ant 1.4. In Ant 1.5.1, there is apparently some new features in the
style task that allow the specification of an alternate EntityResolver that
would allow me to avoid hardcoding the name of the directory the file is in.

And finally, here is the stylesheet (webmerge.xsl) that does the
transformation:

then all the remaining elements of the main file (which will be

Re: jsp precompilation
You might want to look at a mixture between JSPC (Tomcat) and Ant I'm searching a script ( bash-unix and/or bat-windows ) You should then use Ant and create Ant tasks that you need (if you need to write some...) that would : - generate java files from jsp - compile generated java files use JSPC (why not within Ant ? I don't remember if JSPC has a task on its own but you can write one if it does not, or use a simple shell-command task) - compile servlet java files Use Ant and the JDK you're working with - create the .war Definitely, you should use Ant ;-) http://jakarta.apache.org/ant Cheers Denis -- To unsubscribe: mailto:[EMAIL PROTECTED] For additional commands: mailto:[EMAIL PROTECTED] Troubles with the list: mailto:[EMAIL PROTECTED]

In Tomcat's ./bin dir there is jasper.sh, this is how you invoke it:
${CATALINA_HOME}/bin/jasper.sh jspc MyPage.jsp
This will produce MyPage.java
- compile generated java files
javac -classpath ${CATALINA_HOME}/common/lib/servlet.jar MyPage.java
- compile servlet java files
javac MyServlet.java
- create the .war
mv MyPage.class ${MY_WEB_APP_HOME}/WEB-INF/classes/path/to/my/package/
jar cf MyWebApp.war ${MY_WEB_APP_HOME}
Or be advanced - make a build.xml for Ant and do it that way.
