php-java-bridge-users Mailing List for PHP/Java Bridge

I am new to the php-java-bridge and am experimenting with it. There  
is probably something obvious that I am not seeing, but I cannot get  
a simple example Java to PHP application bridge working. I used the  
latest Debian packages which are using version 4.0.8a of the php-java- 
bridge. I can see via phpinfo() that php-java-bridge is installed and  
running via Apache2.2 right now. The following application works fine  
(I got it from the examples page):

Java:

public class HelloWorld {
	private String hw = "Hello World";

	public String getHelloWorld() {
		return hw;
	}
}

PHP:

<?php

java_require('http://192.168.1.128/java/HelloWorld.jar');
$myObj = new Java('HelloWorld');

// display Hello World
echo (String) $myObj->getHelloWorld();

?>


However, if I change the Java and PHP to the following, then I get  
the following exception output:

Hello World
Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: Invoke  
failed: [[o:HelloWorld]]->setHellowWorld([o:PhpParserString]). Cause:  
java.lang.NoSuchMethodException: setHellowWorld([o:PhpParserString]).  
Candidates: [] Responsible VM: 1.5.0_11@http://java.sun.com/" at: #-5  
php.java.bridge.JavaBridge.Invoke(JavaBridge.java:1106) #-4  
php.java.bridge.Request.handleRequest(Request.java:342) #-3  
php.java.bridge.Request.handleRequests(Request.java:388) #0 [internal

projects/java_bridge/HelloWorld.php(9): Java->setHellowWorld('Hello  
world, on...') #2 {main}] thrown in /home/jhodapp/projects/ 
java_bridge/HelloWorld.php on line 9


Changed Java (throws exception):

public class HelloWorld {
	private String hw = "Hello World";

	public String getHelloWorld() {
		return hw;
	}

	public void setHelloWorld(String incoming) {
		hw = incoming;
	}
}

Changed PHP (throws exception):

<?php

java_require('http://192.168.1.128/java/HelloWorld.jar');
$myObj = new Java('HelloWorld');

// display Hello World
echo (String) $myObj->getHelloWorld();

$myObj->setHellowWorld((String) "Hello world, once again.");

?>


Once I add my own method in the Java source, it no longer seems to  
work. I'm compiling this via "javac HelloWorld.java" and making a jar  
via: "jar cvf HelloWorld.jar HelloWorld.class"

Is there something wrong with my setup? The site seems to be good at  
helping you get setup with php-java-bridge for your OS environment,  
but lacks good documentation from that point.

Thanks,

Hi,

I assume your setup is like this:

http://www.onjava.com/pub/a/onjava/2004/03/31/clustering.html

If I understand this correctly, the management node
must detect the failure of one of the cluster nodes
and   switch it off.

I haven't tested the bridge in a cluster environment
(we should do this, though); the bridge is a standard
web application so that the operation mode of the J2EE
environment should be completely transparent.

Which cluster algorithm do you use? Do you use
sessions? How do you store the sessions?


Regards,
Jost Boekemeier
