OC4J and php

Configuration

Every web application can specify a set of welcome-files.

In WEBAPP/WEB-INF/web.xml, make sure you have the following:

<welcome-file-list>
<welcome-file>index.php</welcome-file>
</welcome-file-list>

Note that running PHP from within OC4J can be not only interesting, but very slow compared to using JSP or servlets instead. Consider fronting OC4J with Apache or something else that can embed PHP directly to save the extra overhead of external process invocation.

In global-web-application.xml :

<servlet>
   <servlet-name>php</servlet-name>
      <servlet-class>com.evermind.server.http.CGIServlet</servlet-class>
      <init-param>
        <param-name>interpreter</param-name>
        <param-value>php</param-value>
      </init-param>
    </servlet>

Difference between php and php-cgi

File hello_world.php in C:\php\

<?php phpinfo(); ?>

In a command dos

C:\PHP>php-cgi.exe hello_world.php

Using PHP-Java Bridges with WebLogic Server

This is a free, open-source offering that wraps the Zend core engine. You can configure it to operate in the same way as the Zend Platform bridge shown above (that is, as a connection between an Apache/PHP configuration and a Java EE Server). This bridge also works in an additional configuration: It can be deployed as a Java servlet, as shown in Figure 2.

To install the SourceForge Java Bridge:

1. Download a version from the SourceForge site. We used php-java-bridge_3.2.1_j2ee.zip for this tutorial.
2. Open the zip file and extract JavaBridge.war.
3. Explode JavaBridge.war into a new folder in an Eclipse workspace. (We called it “JavaBridge”.)
4. Deploy the application to WebLogic Server.
5. Point a Web browser at http://localhost:7001/JavaBridge. The index.php will present several example programs that demonstrate the bridge.

Running SourceForge Java Bridge as a PHP servlet

In this configuration:

1. The PHP request arrives and is mapped by WebLogic Server to the bridge's PHP servlet.
2. The PHP script is passed to a php-cgi instance for processing.
3. The bridge passes calls to Java objects into the WebLogic Server JVM through requests to its Java Gateway servlet.
4. From there, access to JNDI resources happens in the usual way.

Helpful hints:

• In the servlet configuration, by default, this bridge shells out a CGI process for each invocation of PHP, which terminates at the end of the request. In an environment where more than an occasional PHP request is run, this can lead to performance problems. The bridge distribution contains instructions for configuring FastCGI, which will maintain a pool of PHP address spaces and dispatch incoming requests to idle ones; this approach avoids the overhead of operating-system process initiation and termination for each request. The challenge involved in setting up this feature varies among operating-system platforms.
