Re: precompiling JSPs -- how to resolve references normally resolved by apache?
Unless you have a directory ${TOP}/web/html/jsp/jsp your uribase/uriroot
probably aren't right.

Hi,

The problem I have run into is that we are using apache +

Inside some of our servlets and JSPs, they refer to other
jsps using the absolute URL /jsp/ which works in deployed

one JSP we have %@ include file=/jsp/Header.jsp %
I setup the tomcat-4.1.30 ant jspc task and it was giving a
NPE. Then I tried the Ant Jspc optional task, and it gave
me an error message:
the file '\Status.jsp' generated the following general
exceptionn: org.apache.jasper.JasperExeption:

Is there any quick and dirty way to get the JspC to resolve
the /jsp/*.jsp urls to *.jsp or is there no way?
My alternative is to try to change all the /jsp/*.jsp
references to *.jsp everywhere we do an %@ include % or
jsp:include/ or jsp:forward/. I think that would be ok
since those directices are handled on the tomcat side. Changing
it would be kind of messy since we have a ton of JSPs in a
large directory hierarchy, so some of those /jsp/Header.jsp
references would have to be changed to ../../Header.jsp, etc.
I know I can't get away from the /jsp mapping completely
because we have URLs and HTTP redirects which depend on it.

Re: precompiling JSPs -- how to resolve references normally resolved by apache?
Jon,
Thanks for your help. The uribase and uriroot were not set correctly.
Here is the final version that I got working. I had one additional twist
that
I needed to copy the JSP files to another location first using the ant
copy
task.
I set uriroot to the webapps root {dir}/html, and then jasper2
automatically
found the JSP files in the subdirectories under jsp/** and correctly
resolved
the references /jsp/**.jsp inside the JSP files.
Once it works, it's great. But it several hours of frustration because
tomcat4.x jasper often just print NullPointerExceptions instead of an
error message. So you have to guess what is wrong.

Precompiling JSPs fails
Hi, Im using Tomcat 5.5.9 and JDK 1.5.0_02. Im trying to precompile the
Liferay Pro Portal 3.2 JSPs using the ant build script found on the apache
web site:
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jasper-howto.html#Web%20Appl
ication%20Compilation
modified to add jars placed in common/lib/ext. JAVA_HOME is set to
/usr/java/jdk1.5.0_02.
When I run the ant script, I get a NullPointerException. Below is the
script I am using and the output from the ant command. Any idea what I
might be doing wrong?

Precompiling jsps in different directories does not produce right servlet mappings (jasper issue)
Hi all,
I have tried to google to find solution to my problem, but had no luck,
and thus I am writing to this list.
Also, I tried to search through archives and did not hit on any solution
yet.
I am using these two tasks (shown at the end of this email) in the ant
file with Tomcat version 4.1.31 for precompiling jsps.
I am using this because I want my jsps to be precompiled and also
because I want the web.xml file to
be populated automatically with all the servlet mappings for the jsps.
It works fine for all the jsp files which are under the directory
${basedir}/web (one specified as uriroot for the jasper2 task).
But I have a jsp in directory as file
${basedir}/web/level1/level2/bookreg_error.jsp.
For this jsp file, the class is built in the right hierarchy,
the class file is in location
${basedir}/war/WEB-INF/classes/${app.name}/level1/level2/bookreg_error.c
lass. (which is what i expected)
But the servlet mapping is still as follows (which I did not expect) in
the generated_web.xml file.
servlet
servlet-namesic.bookreg_error_jsp/servlet-name
servlet-classsic.bookreg_error_jsp/servlet-class
/servlet
servlet-mapping
servlet-namesic.bookreg_error_jsp/servlet-name
url-pattern/bookreg_error.jsp/url-pattern
/servlet-mapping
There is actually no class called sic.bookreg_error_jsp but only class
is sic.level1.level2.bookreg_error_jsp.
Instead I was expecting the generated_web.xml file to have following
entry.
servlet
servlet-namesic.level1.level2.bookreg_error_jsp/servlet-name
servlet-classsic.level1.level2.bookreg_error_jsp/servlet-class
/servlet
servlet-mapping
servlet-namesic.level1.level2.bookreg_error_jsp/servlet-name
url-pattern/level1/level2/bookreg_error.jsp/url-pattern
/servlet-mapping
Can somebody please help me here. Normally, I think jsps should all be
in one directory.
Does this org.apache.jasper.JspC assume that all jsps should be only in
the uriroot level to create the servlet mappings.
Thanks in advance...
Shweta

Re: Precompiling JSPs
Here's my problem with JspC task:
does not factor in class or taglib dependencies, or jsp:include
references.
Quote from the page mentioned below!!
I need these things factored in or else you cannot run javac on these *.java
files.
Thanks,

You should read up on the JspC task:
http://ant.apache.org/manual/OptionalTasks/jspc.html
The JspC task will compile your jsp file to a java servlet (.java) file.
Then you can run javac/ to get your class files.
You will need to download the jasper-compiler.jar and jasper-runtime.jar
files.
I currently do this in ant:

project I've done for years. I should probably go learn ANT or
some other build technique but for now I want to do this the
command line way. I'm not even sure if ANT will do what I want.
I want to have my .jsp files made into .java files (easy) then
compiled into .class files (hard) before starting my Tomcat.
That way I can see any syntax errors in my .jsp files.
If I do this at the moment I get a load of errors where one JSP
which is included in another uses variables which are only
declared in the major one.
Is there a way to compile the .java files the way Tomcat does
(which takes account of included .jsp's)?
Does ANT create .class files?
Thanks in advance.
Andoni.

Andoni, Justin Ruthenbeck helped me with this situation. Direct your browser to: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper-howto.html and look at Web Application Compilation.

RE: Precompiling JSPs
You should read up on the JspC task:
http://ant.apache.org/manual/OptionalTasks/jspc.html
The JspC task will compile your jsp file to a java servlet (.java) file.
Then you can run javac/ to get your class files.
You will need to download the jasper-compiler.jar and jasper-runtime.jar
files.
I currently do this in ant:
Here is what my project for compiling my jsps looks like:
project name=PW_JSPS default=build basedir=.
target name=build
property name=JSP_ROOT value=${WEB_MAIN}/src/java/jsp/
property name=JSP2JAVA_DIR value=${WEB_OUT}/jsp2java/
mkdir dir=${JSP2JAVA_DIR}/

Thanks, Rossen.
However, I still have two problems when I run the above.
1. The resulting .class file does not have the XXX$jsp.class naming that
results from having Tomcat compile it on-the-fly. Thus, Tomcat doesn't use
my pre-compiled tax.
2. Also, I'm having trouble with variables being shared across pages, i.e.,
pages that define a variable, and then use the same variable in an included
page. This is valid, but the precompilation bombs on this.
TIA,

some doubts abt precompiling jsps.
Hai all, As suggested I can precompile the jsps to classes,but the problem is 1)With jspc I am able to parse the jsps to java files.Now I can compile.But tomcat follows its own naming convention when compiling the jsps to classes upon request(if it is not precompiled).Shall I have to follow the conventions in to make tomcat recognize it.But one solution sugested is $./jspc.sh -webxml $TOMCAT_HOME/webapps/urcontext/WEB-INF/web.xml -d $TOMCAT_HOME/webapps/urcontext/WEB-INF/classes -webapp $TOMCAT_HOME/webapps/urcontext/ It parses the jsp files in the context urcontext to java files to my classes folder now I have to compile it. It generates the web.xml file which maps the jsp request to a compile servlet. According to my understanding each web application will have one JSPServlet instance and depending on the request the corresponding pages will be shown as the output stream of JSPServlet.(This is what I infer from the extension mapping in the ROOT web.xml file).If I generate the web.xml which points to each request to each servlet,It will lead to many servlets instanaces instead of one JSPServlet. Any other solution . kamesh jayachandran -- I would suggest you to read through the following book and files: * Kernighan Pike, The Practice of Programming * Documentation/CodingStyle * drivers/net/aironet4500_proc.c and consider, erm, discrepancies. On the second thought, reading KR might also be useful. IOW, no offense, but your C is bad beyond belief. - Al Viro
