Install PHP/Java Bridge

If you are using a RedHat Linux system (RedHat Enterprise or Fedora), you can download a 32-bit RPM package from the home page and enter the rpm-I php-java-bridge-v.x.y-z-i386.rpm to install it. If you are using a 64-bit system and a 64-bit virtual machine, you need to install a 64-bit RPM package. For other systems, see the following introduction.

(1) before installing PHP/Java Bridge, make sure you have installed:
Java1.4 or later,
Gcc3.2 or later,
Apache1.3 or later,
Autoconf2.57 or later, Done
Libtool 1.4.3 or later, Done
Automake1.6.3 or later,
GNU make Done
Php4.3.2 or later

You can run the java-version, gcc -- version, apachectl-version, libtool -- version, automake -- version, make null -- version, autoconf -- version and php-config commands? To determine the version of these packages.

(2) Download the source code of PHP/Java Bridge
Http://www.sourceforge.net/projects/php-java-bridge

(3)
Decompress: cat php-java-bridge_v.x.y.tar.bz2 | bunzip2 | tar xf?

(4)

Run the following command in the extracted directory php-java-bridge-v.x.y:

Phpize &./configure -- disable-servlet -- with-java =/opt/IBMJava2-14 & make CFLAGS = "-m32"

Generate a module for a 32-bit JVM.

(5) install the generated module
Su-c 'make install'

(6) PHP/Java Bridge can be run as sub-component of the WEB server. add the following line to php. ini, or write this line to a file java. ini. copy ini to the directory that contains the description of the php module, such as/etc/php. d /.

Extension = java. so
[Java]

(7) restart the apache Server:/www/apache/bin/apachectl restart

(8) now you can test web installation. Copy test. php to the root directory of the site (for example,/var/www/html) and access it through a browser. You can see that the bridge module is activated and running. Bridge will start as the server starts.

Test. php

Phpinfo ();

Print "\ n ";

$ V = new java ("java. lang. System ");

$ Arr = $ v-> getProperties ();

Foreach ($ arr as $ key => $ value ){

Print $ key. "->". $ value ."
\ N ";

}

?>

Installation on Windows:

1. decompress php-java-bridge_2.0.4-win32-php5.zip and copy all files to C: \ php.

2. double-click c: \ php5 \ JavaBridge. jar or execute java-jar JavaBridge. jar in the command line.

3. php-cgi test. php> result.html (test. php source code can be found in the previous example)

4. open result.html with a browser to view the running result.

The test program first outputs all the options of the php environment, and then creates a Java object and returns its related information.

Running result:

Here, we can freely communicate with Java objects and implement the bridge between PHP and Java.

5. modify your php. ini (C: \ Windows \ php. ini) and remove the semicolon before extension = php_java.dll.

Note that php also comes with a php_java.dll located in C: \ php \ extensions, which is different from that provided by php-java-bridge. To avoid errors, set extension_dir in php. ini. by default, extension_dir = "./" points to the C: \ php directory.
