Configure JDK and PHP to call java classes in linux

In linux, configure JDK and PHP to call the java class-general Linux technology-Linux programming and kernel information. The following is a detailed description. Original: zhuzhu
For work purposes, you must configure PHP to call the java class in linux. I searched the internet and found a lot of information, but the system and JDK versions of each person are different. Therefore, debugging fails during configuration. After two days of installation and debugging, I finally got a lot of experience and lessons. It also reminds people who need PHP to call the java class.

Contact PHP and JAVA, of course, php-java-bridge.

System Environment: CentOs5.1 + apahe2.2.8 + PHP5.2.6
Jdk version: jdk-1_5_0_06-linux-i586.bin (rpm-ivh package name for. rpm packages)
Php-java-bridge: php-java-bridge_4.0.1.tar.gz

1. Install JDK

1. Make it executable: chmod + x jdk-1_5_0_06-linux-i586.bin, get jdk1.5.0 _ 06 (located under/usr/local)

2. ln-s jdk1.5.0 _ 06 jdk

3. Configure the environment variable vi/etc/profile
Add or modify:
JAVA_HOME =/usr/local/jdk
PATH = $ PATH: $ JAVA_HOME/bin
CLASSPATH =.: $ JAVA_HOME/lib

Note: there cannot be spaces before and after "=. If there is a space, an error occurs during terminal connection:
-Bash: JAVA_HOME: command not found
-Bash: CLASSPATH: command not found

Modify the original export statement:
Export JAVA_HOME CLASSPATH PATH USER LOGNAME MAIL HOSTNAME HISTSIZE INPUTRC

4. Test: # java-version

Output:
Java version "1.5.0 _ 06"
Java (TM) 2 Runtime Environment, Standard Edition (build 1.5.0 _ 06-b05)
Java HotSpot (TM) Server VM (build 1.5.0 _ 06-b05, mixed mode)

Indicates that the installation is successful.

Ii. Install javabridge

1. decompress:
Bz2 version: tar jvxf file.name.tar.bz2; gz version: tar zxvf file.name.tar.gz
I used tar.gz version: # tar zxvf php-java-bridge_4.0.1.tar.gz to get php-java-bridge_4.0.1

2. configuration & Compilation:
#/Usr/local/php/bin/phpize &&. /configure -- with-java =/usr/local/jdk1.5.0 _ 06 -- with-php-config =/usr/local/php/bin/php-config & make

3. install: # make install
Generation:/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/(directory names may vary)

3. Configure PHP. INI
