How to make PHP support Java classes under Redhat 9.0

Recently in Linux, PHP support Java classes, I put the debugging notes after finishing the summary written out, I hope that the future debugging will help.

System environment:

Redhat 9.0

Apache-1.3.27

Mysql3.23-54a-11

Php-4.32

J2sdk1.4.1_03

Installation configuration:

1. MySQL is using Redhat9 's own RPM package, does not introduce installation, JDK installation is also very simple, we install JDK to/usr/java/j2sdk1.4.1_03 and set JDK environment parameters in/etc/profile.

2. Compile and install Apache

tar zvxf apache_1.3.27.tar.gz
cd apache_1.3.27
./configure –prefix=/usr/local/apache
–enable-module=so –enable-shared=max
make
make install

3. Compiling and installing PHP

tar zvxf php-4.3.2.tar.gz
cd php-4.3.2
./configure –prefix=/usr/local/php –with-mysql \
--with-apxs=/usr/local/apache/bin/apxs \
--with-java=/usr/java/j2sdk1.4.1_03
make
make install

Modify/usr/local/apache/conf/httpd.conf, find, add in this range

AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps

4. Configure PHP.ini

CP Php.ini.dist/usr/local/php/lib/php.ini

Vim php.ini

Modify the following:

[Java]
java.class.path = /usr/local/php/lib/php/php_java.jar
java.home = /usr/java/j2sdk1.4.1_03
java.library = /usr/java/j2sdk1.4.1_03/jre
/lib/i386/libjava.so
java.library.path =/usr/local/php/lib/php
/extensions/no-debug-non-zts-20020429
extension_dir = /usr/local/php/lib/php
/extensions/no-debug-non-zts-20020429
extension=java.so

Save exit.

cd/usr/local/php/lib/php/extensions/no-debug-non-zts-20020429 ln–s java.so libphp_java.so This step is very important oh!

To set environment variables:

Export Ld_library_path =/usr/java/j2sdk1.4.1_03/jre/lib/i386:/usr/java/j2sdk1.4.1_03/jre/lib/i386/server good! Restart Apache/usr/local/apache/bin/apachectl start

Test, write a test page test.php

<?
$system=new Java("java.lang.System");
//demonstrate property access
print 'Java version='.$system->getProperty('java.version').' <br>';
?>

Normal page should be able to display: Java version=1.4.1_03
