mod_jk README for HP-UX 11

This README explains how to build mod_jk on HP-UX 11 systems.

There are two build scripts for HP-UX:

build-hpux.sh         Use if you have the GNU gcc compiler
build-hpux-cc.sh      Use if you have the HP ANSI C compiler

The first package is for use with the gcc compiler.  It produces 32-bit
code that should run on both PA1.1 and PA2.0 based architectures.

The second script is for use with the HP add-on ANSI C Complier package.
This will not work with the stripped down cc version that ships with
HP-UX.  That compiler is just for kernel rebuilds.  If you do not have
the HP ANSI C compiler package, then obtain gcc and use the first script.

PREREQUISITES

This script requires that GCC 2.95.2 be installed and in your path.
You should also have the GNU binutils installed.  You can obtain
the binary depot files for these at:

http://gatekeep.cs.utah.edu/

Before running the build script, verify that APACHE_HOME and
JAVA_HOME are set correct in the script.

BUILDING MOD_JK

The build script should be run as root as follows:

# sh build-hpux.sh

After the script completes you will need to modify the Tomcat
server.xml file to tell it to generate the auto configuration
for mod_jk.

To do this, edit $TOMCAT_HOME/conf/server.xml and add the following
after <AutoWebApp dir="webapps" host="DEFAULT" />

       	<ApacheConfig />

The next time you startup Tomcat, it will generate
TOMCAT_HOME/conf/jk/mod_jk.conf-auto with the necessary
commands to use Tomcat through Apache.  Tomcat will automatically
add any webapps that it finds in its webapps directory.

See the Tomcat Users Guide and Release Notes for more information.


TROUBLESHOOTING

If you experience problems using the build script, make sure that your
apache installation matches your system.  Apache's apxs is a perl
script that is configured when you compile apache for your system.
If you are using a binary install of apache, it will most likely not
be configured correctly for your system.

NOTE: Most apxs errors are due to the use of an Apache binary
      installation.
      BUILD AND INSTALL APACHE FROM SOURCE.  IT'S NOT THAT HARD!

The best solution is to build apache from source as follows:

Download apache from http://httpd.apache.org
Put the source file in /usr/local/src

# cd /usr/local/src
# gzip -dc apache_1.3.17.tar.gz|tar xvf -
# cd apache_1.3.17
# ./configure --prefix=/usr/local/apache --enable-module=most /
  --enable-shared=max
# make
# make install

This will build apache and install it into the /usr/local/apache directory.


Note:

In order to build mod_jk for HPUX11 using GCC, support for JNI was removed.
This should not affect Apache 1.3 installations since it is not recommended
to run mod_jk in In-Process mode under Apache 1.3.

If you wish to include support for JNI, you must build mod_jk with the
HP ANSI Compiler using 64-bit mode.  The second build script listed at the
top of this document will work.
