Re: RequestDispatcher and [contentType] question...
Yansheng Lin wrote: Hi, You are confused with request and response. The request is shared by the forwarding jsp and the forwarded jsp, not the response(well kind of, but not until it's being generated). You will have to explicitly set the response contentType to utf-8 in the forwarded page. -Yan I see what you mean. How I put it together in my mind--naively I can't say--is that the servlet begins constructing a response buffer to the request and the contentType gets set by res.setContentType(). Shortly following this, the request and response are forwarded for additional processing by a JSP page. Upon which the response buffer is cleared as it has not been committed. Since no attribute to the page directive is provided in the JSP, the default behavior is to set the contentType to text/html;charset=ISO-8859-1. The response returns to the controlling servlet and gets committed to the client, having overwritten the original call to setContentType. Lesson learned: if one forwards control to a JSP page, the page directive must set contentType and/or pageEncoding, either electively or by requirement, otherwise the JSP defaults will supersede any work done prior to the forwarding of the request.

Windows XP, TC 4.1.29 and logging question (catalina.out)...
List, I must be too close to the problem, having a background in managing Tomcat on Linux, I can't seem to figure out what is so drastically different about Tomcat on Windows that logging doesn't behave the same. Specifically: c:\%tomcat_home%\bin\startup.bat runs in a separate window (expected) but only the following logs are being generated: localhost_examples* localhost_admin* localhost_log* 'catalina* is conspicuously missing. However, the Logger is defined in the server.xml file! There is some standard out logging going on, but not to a file. What directive am I missing? The archives didn't seem to answer my question directly. The server.xml file seems to implied that the global logger could be overridden, but I have not explictly stated any such overriding the server.xml is out-of-the-box. Many thanks in advance.

My current experience is has been the x.42 builds will work in x.47+ of Apache (I'm using x.42 on my Windoze boxes with success against x.48 of Apache currently).

Successful build of mod_jk2 on Mac OS X Panther
List,
I have successfully built mod_jk2 on Mac OS X Panther (10.3.2).
I document my success at:
http://forums.serverlogistics.com/viewtopic.php?t=644
*where comments are welcome.* NB: My success in part may be due to using
ServerLogistic's Complete Apache 2.0.48 distro, so it is somewhat
specific to this Apache build, however, I intend to extend my experience
with an Apache build from source on Mac OS X, something that I have done
serveral times on Linux.
For posterity and convenience, I'm including my notes posted at
ServerLogistics here:
How did you build mod_jk2 for Mac OS X? I answer my own question but
solicit review and feedback as IANAUD (I Am Not A UNIX Developer). I
made best guesses about what should be done to fix build errors I
encountered from my experiences with building software on Linux.
!!! I have not tested this build in a test or production environment
very extensively.
Make sure you have installed the Developer Tools for Panther. You will
find these on the XCode CD.
The following guide may require that you have installed Complete Apache
2.0.48 from ServerLogistics.
[Complete Apache 2.0.48]
http://www.serverlogistics.com/apache2.php#download
1. Download and unpack the JTC source. Where you download it to is
not important, but will be referred to later as ${JTC_SRC_ROOT}.
Code:
% tar xvzf ${JTC_SRC}.tar.gz
[JTC_SRC]
http://jakarta.apache.org/site/sourceindex.cgi
2. Download and unpack the PERL Compatability Regular Expression
Library. Again, I will refer to it as ${PCRE_SRC_ROOT}. I used v4.4. It
is stated on the home page (1/7/2004) as the most recent version.
However, FTP has a v4.5 available.
Code:
% tar xvzf ${PCRE_SRC}.tar.gz
[PCRE_SRC]
http://www.pcre.org/
3. PCRE builds out-of-the-box on Mac OS X Panther. I built the
default configuration save support for UTF-8.
Code:
% cd ${PCRE_SRC_ROOT}
% ./configure --enable-utf8
...
...
% make
% make install
This installs the pcre libs in /usr/local/lib. One can use the
--prefix=[DIR] flag during configure if wanted. ./configure --help
explains this and much more.
4. I originally said something about the Apache Portable Runtime.
APR is included with Complete Apache 2.0.48. See note above about
installing Complete Apache2 before continuing further.
5. Fix ${JTC_SRC_ROOT}/jk/native2/buildconf.sh. Mac OS X does not
have the libtoolize tool, but a generic libtoolize. vi/bbedit the
first line and replace libtoolize with glibtoolize.
Code:
% cd ${JTC_SRC_ROOT}/jk/native2
vi buildconf.sh
6. Run the fixed buildconf.sh.
Code:
% ./buildconf.sh
7. Now you're ready to run the configure script.
Code:
% ./configure \
--with-apxs2=${APACHE_ROOT}/bin/apxs \
--with-tomcat41=${TOMCAT_ROOT} \
--with-java-home=/Library/Java/Home \
--with-jni \
--with-pcre
[from Tomcat User and Jakarta Tip]
http://marc.theaimsgroup.com/?l=tomcat-userm=105103815630094w=2
The configure script is going to create a bunch of Makefiles. The
Makefiles do not seem to account for the idiosyncroacies of Mac OS X
Panther. You have to find references to -lcrypt. The -lcrypt flag is
not supported in Mac OS X. These functions are builtin to the OS and
found in unistd.
[lcrypt flag support notes]
http://developer.apple.com/technotes/tn2002/tn2071.html#Section17
Also, configure is going to build a libtool in the current
directory, but the Makefiles are going to reference the libtool found in
/Library/Apache2. I don't know why. So we need to edit this variable too.
8. Two files are of interest... ${JTC_SRC_ROOT}
/jk/native2/server/apache2/Makefile and ${JTC_SRC_ROOT}
/jk/native2/server/apache2/Makefile.in. Find the JK_LDFLAGS and remove
-lcrypt references.
Also replace the LIBTOOL value with LIBTOOL=../../libtool .
9. Now you're ready to make.
Code:
% cd ${JTC_SRC_ROOT}/jk/native2
% make
10. Hopefully you should have a successful build.
11. At the end of make there is a request that one invoke libtool to
finish with:
Code:
libtool --finish ...
This has never work for me so I just manually copy the files.
Code:
% cp ${JTC_SRC_ROOT}/jk/build/jk2/apache2/mod_jk2.so
${APACHE_ROOT}/modules
% cp ${JTC_SRC_ROOT}/jk/build/jk2/apache2/jkjni.so
${TOMCAT_ROOT}/server/lib
Double check your module permissions!
12. The rest of the configuration is well documented at Jakarta.
I'm very interested in feedback and will attempt to answer questions
when possible.

Re: How to set the user runnig tomcat ? ( + start/stop problem)
Julien, If I can just provide you some feedback, at least if only to let you know that someone is reading and following this thread. :) I'm am trying to do the same, not on Linux but Mac OS X. I'm very interested in this as well. That said, allow me to provide some comments on your post: Julien Oix wrote: I used to run a tomcat 4.1.18 rpm on a linux top box, where I put the TOMCAT_USER variable in a tomcat4.conf file ( nobody user in my case ...) As an RPM, the tomcat4.conf file probably provides variables that are passed to the init.d scripts for startup and shutdown. Now i try to upgrade to 4.1.29 full archive (jakarta-tomcat-4.1.29.tar.gz) and I didn't see any doc's on configuring this variable .. As noted, the tomcat4.conf file is a Linux convention, likely for convenience. This file is not going be in the binary distribution of Tomcat from Jakarta. I would like to request a copy of both the conf file and the init.d script loaded by the RPM. It may provide clues valuable in your quest and my quest on Mac OS X. In Mac OS X, similar to the init.d scripts, a script is placed in a StartupItems folder and executed as root. However, as one might guess, this results in the process being owned by root. I have not found a working method of changing this, including, as you suggest below: Is the only solution to execute the startup.sh script as the running user ? ( the command line under a root session could be : su - nobody -c $CATALINA_HOME/bin/startup.sh ) Thus, the reason I request the conf and init.d script files. Valuable clues may be found in each that could help us both. Another problem: I start tomcat with the method up in the message: [EMAIL PROTECTED] # su - nobody -c $CATALINA_HOME/bin/startup.sh Using CATALINA_BASE: /var/tomcat Using CATALINA_HOME: /var/tomcat Using CATALINA_TMPDIR: /var/tomcat/temp Using JAVA_HOME: /usr/java/java [EMAIL PROTECTED] # ps -aux -- gives the process ran by nobody ...

Starting Tomcat as nobody...
I have been devouring /Tomcat: TDG/ by Brittain and Darwin. I have regularly been using Tomcat for years, but some of security tips found in this book are valuable gems indeed. One such as installing Tomcat as a low- or non-privileged user like nobody. I know about the nobody user, starting Apache in this fashion however is handled for by the binary, first as root to bind to port 80, then as nobody for requests. (I'm aware of the work going on with commons-daemon, it is covered in TC:TDG. However, I'm more focused on getting a binary install of Tomcat running as nobody.) Specifically I'll quote the book here... First, switch to the user that you'd like to run Tomcat as. This will ensure that all of Tomcat's files will start out with the correct Unix file permissions. For security reasons, you sohuld probably run Tomcat as the nobody user or create a new tomcat user with similarly low privileges. We suggest settin that user's login shell to /bin/false and locking the user's password so that it can't be guessed. Later, under notes on installing on Mac OS X, the authors offer a directory listing showing a Tomcat install under the nobody user. Okay, so I know the su - [username] -s [shell] command. But how do I log in as a user without knowing, or the user having, a password? My best first guess is, su as root then: % su Password: #su -m nobody -s /bin/bash Thoughts? Okay, say the above is legit and Tomcat installed (tar -zvfx ...) as said user. Now, how do I start Tomcat as said user? It seems defeatist, at best, to have to login as root to start Tomcat. If I set permissions say 750 (rwxr-x---, this permission is shown in the aforemention Mac OS X directory listing) when I login as a administrative user... I'm doing development here, so maybe this is overkill, but developing closer to the production environment could be argued as a good thing.

BTW: In this case it doesn't matter if you use mod_jk or mod_jk2, both are capable of doing this kind of loadbalancing. Ralph, thank you. I have a working production environment using the UBeans tutorial. But I think I was looking to update its design a bit. If I have the following servers, REED and DOUTRICH, then I need to *update* my worker.properties file as such: #-- # Tomcat Server One: REED #-- worker.TomcatREED.port=8009 worker.TomcatREED.host=10.102.1.4 worker.TomcatREED.type=ajp13 # Specify the load balance factor when used with # a load balancing worker # Note: # lbfactor must be 0 # Low lbfactor means less work done by the worker. worker.TomcatREED.lbfactor=100 #-- # Tomcat Server Two: DOUTRICH #-- worker.TomcatDOUTRICH.port=8009 worker.TomcatDOUTRICH.host=10.102.1.5 worker.TomcatDOUTRICH.type=ajp13 worker.TomcatDOUTRICH.lbfactor=100 I think I had questions about the use of port and host properties. But your suggestions seem to validate what I was thinking needed to be done. Since the loadbalanced Tomcats are on distinct servers I can use 8009 on DOUTRICH and 8009 on REED. I have to make sure that my host properties is distinct! (I would likely change them for distinguishing reasons however.) I could drop this config (with a little more detail into each apache (one on REED and one on DOUTRICH) and the tomcats would find each other.

Excellent resource BTW. It noted, as both Tim and Yoav caught, that when RequestDispatcher#forward is part of an executing method in the caller, control is indeed returned! D'oh! CNJ2EE offered two workarounds: One: as noted, return explicitly from the executing method OR Two: explictly use out.close() in the called resource. (not useful when the called resource is static HTML with a JSP extension to support HTTP POST I guess) As in all the earlier notes I had run across, and the source of my confusion, RequestDispatcher#forward is stated as passing control *permanently* to the called resource. The use of permanently may not be best. It brings to mind Vizzini's use of inconceivable and Inigo Montoya's observation: You keep using that word.

RequestDispatcher anomolies (Tomcat v4.1.24)
List,
I'm having some trouble with using a RequestDispatcher, it works and
doesn't work.
#doPost( req, res )
...
50 Customer customer =
51 Customer.findCustomer( emailAddress, custData);
52
53 if(( customer == null ) ||
54( password == null ) ||
55( !password.equals( customer.getPassword() ))) {
56System.out.println( one );
57gotoPage( /move/accounts.jsp, request, response );
58System.out.println( four );
59 }
60
61 customer.setStartDate( request.getParameter( startDate ) );
...
69 // branching code for other forwards
70 HttpSession session = request.getSession( true );
71
72 session.setAttribute( customer, customer );
73 if( request.getParameter( rooms ) != null ) {
74 gotoPage( /move/roomCount.jsp, request, response );
75 } else if( request.getParameter( floors ) != null ) {
76 gotoPage( /move/floorCount.jsp, request, response );
77 } ...
#gotoPage( url, req, res )
private void gotoPage( String address,
HttpServletRequest request,
HttpServletResponse response )
throws ServletException, IOException {
RequestDispatcher dispatcher =
getServletContext().getRequestDispatcher( address );
System.out.println( two );
dispatcher.forward( request, response );
System.out.println( three );
}
Basically, the idea is if the user forgets to enter a username or
password, the servlet should forward--via gotoPage( url, req, res )-- to
accounts.jsp. This blows up with a NPE at line 61 everytime (the lookup
for the customer returns null, so the NPE is expected). Looking at
standard out I see:
one
two
three
four
This shows that the test for null passed and the call to gotoPage worked
as expected but passed through and continued to process the page, null
reference be damned.
Yet, if the user correctly completes the form, all is fine and the
dispatcher created in gotoPage works as expected. Standard out looks like:
one
two
What am I doing wrong that the dispatcher does not like in the first
instance? /travel/accounts.jsp is available.
TIA,
Tim
PS: for those paying attention this code is loosely based on work by
Marty Hall in /More Servlets and JavaServer Pages/

That's why pages like this: http://www.wdvl.com/Authoring/Java/Servlets/request.html that say Any code written in our DispatcherTest servlet after rd.forward(request, response); will not execute as the request is already forwarded are not always to be trusted. Thank you for the link and the test code. Adding a return indeed fixed the problem. My trust in the behavior described in the examples seen in both text and web resources was a little to much. I have to say, the behavior seems almost identical to the described behavior of RequestDispatcher#include since control is given back to the forwarding servlet.

getResourceAsStream and relative paths in web.xml
List,
I'm following a twist on some advice that I got from Yoav Shapira. But
in playing to learn more I ran across something that I have not been
able to solve from reading the documentation.
I want to put the relative path to a user=password property file in the
web.xml. Given:
#web.xml
...
servlet
servlet-nameProtectedPage/servlet-name
servlet-classcoreservlets.ProtectedPage/servlet-class
init-param
param-namepasswordFile/param-name
param-value/WEB-INF/lib/passwords.properties/param-value
!-- want to avoid making this absolute to the file system.
i.e. c:\path\to\file; naturally this is ugly and not
portable.
--
/init-param
/servlet
...
So I got this to work:
...
public void init(ServletConfig config) throws ServletException {
super.init(config);
try {
this.passwordFile = config.getInitParameter( passwordFile );
this.passwords = new Properties();
passwords.load( config.getServletContext()
.getResourceAsStream( passwordFile ) );
} catch( IOException ioe ) {}
}
...
*But* this did not work, which I guess is a relative issue:
...
public void init(ServletConfig config) throws ServletException {
super.init(config);
try {
this.passwordFile = config.getInitParameter( passwordFile );
this.passwords = new Properties();
passwords.load( new FileInputStream( passwordFile );
} catch( IOException ioe ) {}
}
...
Can someone summarize why the second example does not work with relative
paths? I understand why the first one does.
TIA
Tim

Re: getResourceAsStream and relative paths in web.xml
1. Certainly, using a FileXXX class will attempt to interpret the init parameter value (/WEB-INF...) is an absolute path, because that's how absolute paths are defined for files. Thank you again Yoav. The recommendation then is to skip trying to use a FileInputStream (because the String provided is absolute to the file system not servlet context, i.e. /WEB-INF/lib/x.props is intepreted as from root on *NIX and C:\ on Windoze). Additionally config.getServletContext().getResourceAsStream( file ) works in and out of war packages.

CATALINA_BASE --help
Gurus, I'm trying to get a better understanding of the CATALINA_BASE variable. Here is my dilemma (with ASCII art): I have a load balanced Tomcat (v4.0.6) configuration on Win2k using mod_jk + Apache 2. It's all working in a production environment. However, on occassion, about once a month, I have to update a JSP page (don't ask). I have to do this twice...once for each Tomcat instance's webapp. It dawned on me the other day when R'ingTFM that CATALINA_BASE may have been designed for exactly this reason. But the configuration text is confusing. So, do I elect one instance as the master, the other slave? Using CATALINA_BASE set to the master's otherwise CATALINA_HOME? The directory hierarchy then might look something like: /---+ | +tomcatMaster/ || |+webapps/ || |+myWebApp/ | +tomcatSlave/ | +webapps/ | +...otherwise.empty... ## somewhere in Windoze or Linux # setenv CATALINA_BASE /tomcatMaster ## Is this the correct understanding and use?
