NOTE: Linux RPMs contain Security Enhanced Linux contexts. If you want
to install software on a SEL system (RHEL, Fedora, ...), please use
the RPM build system instead (rpmbuild --rebuild
php-java-bridge*src.rpm).  However, for a development system you can
switch off SEL and follow the instructions below.


Quick Installation from source code
-----------------------------------
mkdir dist

(cd automake-1.9; ./configure --prefix=$INST && make && make install)
(cd libtool-1.5.20; ./configure --prefix=$INST && make && make install)
(cd php-5.*; ./configure --prefix=$INST --disable-all --enable-fastcgi && make && make install)
(cd php-java-bridge-3.*; phpize && ./configure --with-java=/usr/java/jdk1.5.0 && make && make install)

Installation from source code (Solaris, FreeBSD, WinXP or Linux)
----------------------------------------------------------------

The following software components must be installed on your computer:

* an operating system. For example RedHat Enterprise Linux. If you
  build on Solaris, FreeBSD/MacOSX or WinXP, you also need the GNU
  toolchain (gcc, gnu make, autoconf etc.).

* a Java VM. For example IBM JDK 1.4.2 or GNU Java version 3 or above.

* optional: Oracle 9i/10g AS or IBM WebSphere 5/6.


The following instructions build the components:

* the apache web-server

* PHP as a apache module

* the PHP/Java Bridge as a PHP module and/or as a J2EE
  component (plugin) for IBM WebSphere or Oracle AS.

and optionally, if you want to run JSP and PHP from Apache/Tomcat:

* mod_jk with Apache/Tomcat.


# adjust the install directory
INST=/usr/local #INST=$HOME/bridge

# remove all old files under $INST
#rm -rf $INST

# set build path
export PATH=$INST/bin:$PATH 
export LD_LIBRARY_PATH=$INST/lib:$LD_LIBRARY_PATH

# stop the system http service 
su - -c "service httpd stop"

# adjust the java version
JAVA_HOME=/opt/jdk1.4.2
#JRE_HOME=/opt/jre1.6.0 # enable this, if you want to hard-code the JRE path

# The following software components are required during the build
# process: autoconf 2.57, automake 1.6.3 and libtool 1.4.3. If you
# don't have autoconf >= 2.57, automake >= 1.6.3 libtool >= 1.4.3, or
# versions which do not match, for example autoconf 2.59 and libtool
# 1.4.3, you must REMOVE THE OLD VERSIONS and compile and install
# these before proceeding:

(cd autoconf-2.57;  ./configure --prefix=$INST && make && su -c "make install")
(cd automake-1.6.3; ./configure --prefix=$INST && make && su -c "make install")
(cd libtool-1.4.3;  ./configure --prefix=$INST && make && su -c "make install")


#
# BUILD APACHE
# adjust apache MPM.  Prefork is standard behaviour in apache 1.3, worker
# creates worker thread pools which deliver content much faster.  But note:
# some third-party PHP modules may not be thread-safe.
#
MPM=prefork #MPM=worker

# compile and install apache 2
gunzip < httpd-2.x.y.tar.gz | tar xf -
cd httpd-2.x.y
./configure --with-mpm=$MPM --enable-module=so --prefix=$INST
make && su -c "make install"
cd ..


#
# BUILD PHP
#
bunzip2 < php-x.y.z.tar.bz2 | tar xf -
cd php-x.y.z
./configure --prefix=$INST --disable-all --with-apxs2=$INST/bin/apxs
make && su -c "make install"
# now activate php in the httpd.conf
su -c "echo 'AddType application/x-httpd-php .php' >>$INST/conf/httpd.conf"
cd ..


#
# BUILD THE PHP/JAVA BRIDGE
#
bunzip2 < php-java-bridge_p.x.y.tar.bz2 | tar xf -
cd php-java-bridge-p.x.y
phpize
./configure --with-java=$JAVA_HOME,$JRE_HOME
make && su -c "make install"
# now activate the bridge in php.ini
su -c "touch $INST/lib/php.ini && echo -e 'extension=java.so\n[java]' >>$INST/lib/php.ini"
cd ..

# TEST
# create a file phpinfo.php in the document root directory 
# of apache and start the http service
su -c "echo '<?php phpinfo() ?>' >$INST/htdocs/phpinfo.php; chmod +xr $INST/htdocs/phpinfo.php; apachectl restart"

# checking cli, should return "java running"
echo '<?php phpinfo() ?>' | php | fgrep java

# checking web, should return "java running"
wget -olog -O-  http://localhost/phpinfo.php|fgrep java

If the above test succeeded, copy the files "java.so",
"libnatcJavaBridge.so" and "JavaBridge.jar" (on Windows: php_java.dll
and JavaBridge.jar) to the extension_dir of your system php
installation and start the system http service again.

If something went wrong, for example if you have forgotten to set
JAVA_HOME or if configure failed because the installed autoconf
version is too old, you can only remove the build directory and start
from the beginning; removing the autom4te cache directories from the
build directory may be enough sometimes, but not always.



------------------------------------
Installation of Tomcat/mod jk
-----------------------------

Optionally you can install the tomcat servlet engine to serve .jsp
files

Download and extract tomcat into a directory, for example /opt/tomcat5
and set the environment variable CATALINA_HOME, for example:

export CATALINA_HOME=/opt/tomcat5


Download and install mod jk, for example
jakarta-tomcat-connectors-1.2.14.1-src.tar.gz, extract the file into a
folder and type the following commands:

cd jakarta-tomcat-connectors-1.2.14.1-src/jk/native/
./configure --with-apxs=$INST/bin/apxs && make && su -c "make install"

# now activate mod_jk in the httpd.conf, mount the tomcat webapps
# directory and ask tomcat to handle all .jsp files
su -c "echo -e 'LoadModule jk_module modules/mod_jk.so\nJkAutoAlias $CATALINA_HOME/webapps\nJkMount /JavaBridge/*.jsp ajp13\nJkMount /JavaBridge/ ajp13' >>$INST/conf/httpd.conf"

Start tomcat, for example with the command:

$CATALINA_HOME/bin/catalina.sh start


Copy the JavaBridge.war file (which you should have created when
compiling the PHP/Java Bridge, see flag "--enable-servlet" above) from
the modules directory into the tomcat webapps directory, for example
with the command:

cp modules/JavaBridge.war $CATALINA_HOME/webapps

Check if tomcat has created the $CATALINA_HOME/webapps/JavaBridge
directory, if not, please check the tomcat logs for errors.

Direct php to tomcat:
su -c "echo -e 'extension=java.so\n[java]\njava.servlet=User\njava.hosts=127.0.0.1:8080' >$INST/lib/php.ini"

Start or re-start apache, for example with:
su -c "apachectl restart"

Visit http://localhost/JavaBridge and run the supplied examples.

The php .ini file [java] section should contain only java.log_level,
java.servlet and java.hosts entries.  Example:

       [java]
       java.log_level="2"
       java.servlet=User
       java.hosts="127.0.0.1:8080"

The PHP/Java Bridge log output appears in the server log file, for
example in $CATALINA_HOME/logs/localhost_log.*.txt

---------------------------------------------
Compiling the bridge without autoconf
-------------------------------------

Follow these instructions to create a java.so or php_java.dll on
systems which don't have autoconf or if ./configure fails (because the
installed autoconf scripts are too old).

To create a windows php_java.dll you'll need:

* A Unix machine with a C cross compiler, for example
  386-pc-mingw32-gcc

* the standard windows includes in the ./include directory

* the MINGW includes in the ./include directory

* the php5ts.dll in the $PHP directory

* the configured php4 or php5 source distribution in the $PHP
  directory


To create a unix java.so you'll need:

* A unix machine with a C compiler

* the standard unix includes in the /usr/include directory

* the configured php4 or php5 source distribution in the $PHP
  directory


cd to the php-java-bridge* directory and type the following commands:

BRIDGE_VERSION="`cat ./VERSION`"
PHP_JAVA=""
COND_GCJ=0
EXTENSION_NAME=JAVA

# The java executable on windows or unix
#PHP_JAVA_BIN="javaw"
PHP_JAVA_BIN="java"

# The extension_dir on windows or unix
#EXTENSION_DIR="c:/php5"
EXTENSION_DIR="."

# The configured PHP directory, this directory must contain
# the php4ts or php5ts shared library and the header files
#PHP="../php-5.0.3"
PHP="../php-4.4.0"

# The directory which contains the system include files
# for windows (+MINGW include files) or unix
#SYS_INCLUDE="../include"
SYS_INCLUDE="/usr/include"

# The (cross-) compiler for windows or unix
#GCC=386-pc-mingw32-gcc
GCC=gcc

# create init_cfg.h and init_cfg.c
for i in init_cfg.c init_cfg.h; do 
sed "s*@PHP_JAVA@*${PHP_JAVA}*
s*@COND_GCJ@*${COND_GCJ}*
