[Php-java-bridge-users] Zend Java Bridge

[<php...@li...>]

Currently my company is running the Zend Java Bridge that comes with the 
Zend Platform on our production webservers, I was just wondering if 
anyone out there could give me some pros and cons to using the 
php-java-bridge instead of the Zend Java Bridge? With the recent price 
increase in their platform we have started looking into other solutions. 
Any comments would be very appreciated.

Thanks

[Php-java-bridge-users] Cant make it run under Windows :(

[<php...@li...>]

I have installed:
 Apache HTTP Server 2.0.59
 PHP 5.2.0
 JDK 1.5.0_09

 and trying to install PHP-JAVA bridge v3.1.8 - with no success :(

 Here is exactly what I did (what I think should make the Bridge work):

 1) Extracted the JavaBridge archive, and then extracted JavaBridge.war.
 2) Copied WEB-INF/lib to my PHP extensions directory (e.g. c:\php5\ext) and

    then copied WEB-INF/cgi/java-x86-windows.dll to my PHP extensions
directory.
 3) Renamed the dll to php_java.dll
 4) Added the following lines to php.ini :

    extension_dir = "C:/php5/ext"
    extension=php_java.dll

    [java]
    java.java        = "C:/Program Files/Java/jdk1.5.0_09/jre/bin/javaw"
    java.java_home   = "C:/Program Files/Java/jdk1.5.0_09"
    java.log_level = 2
    java.log_file  = "C:/php5/log/java-bridge.log"

 5) Then, I restarted Apache, and executed a php-info file from my
web-servable directory ( phpinfo();).
    In the page, I can not see the Java table (no Java table at all). When I
tried to run some java
    classes from php, I got nothing. (There is an error logged in apache's
error-log, saying that the
    PHP was unable to load/find specified module [I dont remember the exact
form of the error-log, I am
    not sitting at the concerned machine]).


 Can someone help me please? Im running desperate now... :((
 Thank you.

the above message means that your class

it was compiled against an external library, but the
current runtime environment doesn't contain this
method.

You're probably using an old version of the library

[Php-java-bridge-users] java method call causes NoSuchMethodError in dependency of java function body

[<php...@li...>]

Hello,

I am calling successfully several java functions from php, but I have one 
function which produces the following error message:

Fatal error: Uncaught [o(Exception):"java.lang.Exception: Invoke failed: 
[o(PHP2JavaBridge5)]->getEcDatenForOnlineEc2((Ekunden)o(Ekunden)). Cause: 
java.lang.NoSuchMethodError: 
DAL.rmi.SecureTransporter.getEcDatenForOnlineEc(LDAL/PersistentObjects/Ekunden;)DAL/PersistentObjects/EcDaten; 
Responsible VM: 1.5.0_06@http://java.sun.com/" at: #-10 
DAL.rmi.PHP2JavaBridge5.getEcDatenForOnlineEc2(PHP2JavaBridge5.java:338) #-9 
sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) #-8 
sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)


The strange thing is that the method is existing and If I comment out the 
internals of the JAVA-function no error appears and the function can be 
called.

It seems that the Java function getEcDatenForOnlineEc2(..) can only be 
called from PHP, when
the JAVA function doesn't contain a specific line or if it's empty. (see 
below)

My PHP call looks like this and is working (or not working) in dependency of 
the JAVA code:

$this->EcDatenObject = 
$this->jbridge->getEcDatenForOnlineEc2($this->ekunde);


The not working JAVA function looks like:

public EcDaten getEcDatenForOnlineEc2(Ekunden ekunde) {

		EcDaten ec=null;

		try {
			ec=m_obj.getEcDatenForOnlineEc(ekunde);
		} catch (RemoteException e) {
		}
		return ec;
}

the working one looks like:

public EcDaten getEcDatenForOnlineEc2(Ekunden ekunde) {

		EcDaten ec=null;

		/*try {
			ec=m_obj.getEcDatenForOnlineEc(ekunde);
		} catch (RemoteException e) {
		}*/
		return ec;
}

The function call "m_obj.getEcDatenForOnlineEc(..);" which is called inside 
the JAVA function
makes an RMI Call to a server. This is working well for other RMI functions, 
don't know if that matters it's only for completeness.

Of course I tried also the JAVA function alone without calling it from PHP 
and it works perfect.

I can not imagine why the function call from PHP works only when I comment 
out my Java code.

I am already working for days to solve this problem...

Any help is appreciated.

Better:

I don't think there's an official way to clean the JVM
class loaders. The above java_reset() only works when
running within a J2SE or GNU environment. It doesn't
work when you use the recommended J2EE back end,
because J2EE uses its own class loading mechanism.

Hi.

Thanks for the answer. It looks like it's working now.

To set the instance (only once):
java_get_session()->put("DbEnv", $dbenv);

To read it from every PHP request:
$dbenv = java_get_session()->get("DbEnv");

Hi Ovidiu,

if you control the environment in which the bridge
runs, there are certainly ways to do it.

You could store the singleton in the application store
(see
http://php-java-bridge.sourceforge.net/documentation/PHP-API/html/java_8c.html#doc25).
Please also see the FAQ entry which describes how to
start a persistent JVM.

Since Java 6 RC on Linux, Solaris and Windows, users
can simply double-click on the JavaBridge.war file to
start a persistent JVM once.

[Php-java-bridge-users] Class file is cached?

[<php...@li...>]

Hi,

I ran a php file that just prints out some text to test the bridge. I 
then created a new class file with different text. The old text still 
shows! So I just deleted the class file altogether. But running the PHP 
file not give an error it just runs as though the file still exists. So 
I am thinking that it is cached somewhere. I tried the browser cache and 
the temp directories but found nothing.

Any ideas?

thanks

[Php-java-bridge-users] Persistent/shared java object in jvm between requests (not sessions)

[<php...@li...>]

Hi.

I'm trying to implement the following: Berkeley DB <-> JNI <-> Java
<-> php-java-bridge <-> PHP.

I would like to have only _one_ persistent Berkeley DB "Environment"
(a class instance) available to every PHP request (so this is not
something session-specific). The idea would be to somehow create an
instance of an object when the Java VM starts up, and then access it
from all PHP requests.

I need to have this common instance for caching, resource utilization
and concurrency purposes.

Is there any way to do this with php java bridge?

Thank you for your time,

Re: [Php-java-bridge-users] passing objects from PHP to JAVA

[<php...@li...>]

Hi Verena,

> Why did I capture the top-level environment? 

java_closure() without any arguments captures the
top-level environment, creates and returns a Java
proxy for it.

Of cause you could use 

invocable.invokeMethod(engine.get(objectBinding),...)

to call a method[1]. But if you don't have more than
one PHP class per php file, this shouldn't be
necessary; you can capture the object directly, which
has the advantage that you don't need to keep a
dictionary of additional symbol->object bindings.


> thought with engine.get("obj")

Yes. (you'll get a Java proxy for the PHP object).

Yes.

The above script is not invocable. The last line of a
invocable PHP script must contain:

java_context()->call(java_closure());


> java.io.IOException: Bad file descriptor
> 	at java.io.FileOutputStream.writeBytes(Native

Well, PHP simply terminates after a PHP script is
executed. To keep it, you must suspend it and pass
control back to the Java continuation. 

The java_context()->call(kont) 

calls the Java continuation with the PHP continuation
as its argument, so that the Java continuation can
call back into the PHP continuation kont whenever
necessary:

  kont.call(scriptEngine.getContinuation());

Of course the above PHP<->Java continuation passing
style is hidden behind the JSR223 interfaces. But on
the PHP side the java_context()->call() must exist,
otherwise the PHP script cannot be called from a
(potentially) remote Java script engine interface.

In practice, yes.

Just create one public PHP class per PHP file. Example
file my/foo.php, my/bar.php

foo.php:
class my_Foo { function toString() {return "foo";} }
java_context()->call(java_closure(new myFoo());

bar.php:
class my_Bar { function toString() {return "bar";} }
java_context()->call(java_closure(new myBar());


Now you need a XML file which describes your PHP
"beans", or simply hard-code the names in your code:

ScriptEngineManager m = new ScriptEngineManager();
ScriptEngine foo = m.getEngineByName("php");
foo.eval(new FileReader("my/foo.php"));
ScriptEngine bar = m.getEngineByName("php");
bar.eval(new FileReader("my/bar.php"));

// now you can call methods from the foo and bar 
// PHP classes


> No, it instanciates a JavaSript object which has one
> method called hello.

Interesting. I thought that unlike PHP, the JavaScript
object hierarchy is not orthogonal to the Java object
hierarchy.


Regards,
Jost Boekemeier

[1] In the old JSR223 proposal the invokeMethod() and
invokeProcedure() methods where called "invoke()".

Why did I capture the top-level environment? I thought with engine.get("obj") 
I get the PHP object returned and so the method saySomething is invoked on 
that object?
What is the correct syntax to invoke a method on MyClass()?

I tried this:
PhpScriptEngine engine = new PhpScriptEngine();
String s =  "<?php \n";
   s +=	"require_once 'MyClass.php'; \n";
   s += "java_context()->setAttribute( 'obj', java_closure(new MyClass()), 
100 ); \n";
   s +=	"?>";
engine.eval( new StringReader(s) );
Invocable inv = (Invocable) engine;
inv.invokeMethod( engine.get("obj"), "saySomething", new Object() );

and it results in this error message:
Nov 20 10:55:20 JavaBridge ERROR: An exception occured: java.io.IOException:

Yes, it sounds like, but actually I'm not sure how to do it. This faces things 
are about the web framework, aren't they? So how do I transform this to a 
J2SE app?
In the code example I can't see how to call a method on a previously 
instanciated PHP object. It only uses the invoke Method with 2 parameters 
(invokeFunction).

No, it instanciates a JavaSript object which has one method called hello. But 
if the only difference to this snippet and the possibiblities of the php-java 
bridge is the automatic call to java_close(), it is similar enough for my 
project.

Hi Verena,

the above code should work, it evaluates the php
script stored in the Java string s.

However, you'll get a warning that the instance of
MyClass is not a Java object. Use 

  java_closure(new MyClass())

instead. 

> Invocable inv = (Invocable) engine;
> inv.invokeMethod( engine.get("obj"), "saySomething",
> new Object() );

You will get a null pointer exception because obj is
bound to null, see the warning above. Furthermore you
have captured the top-level environment, but you
probably want to invoke methods from MyClass().

Frameworks such as Java Server Faces allow you to
define PHP beans and to inject these beans into the
framework:

http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bridge/examples/java-server-faces/helloWorld.php?revision=1.6&view=markup

  java_context()->call(java_closure(new helloWorld()))

  ||include("index.php");

The above code creates an instance of the PHP
helloWorld() class, creates a Java proxy for it and
then calls the framework (the java_context()->call
magic does this).

When the call() failed (which means that the first
request came in from the web server, and not from the
framework), we redirect to index.php, which forwards
the browser to the framework, which in turn evaluates
the PHP script. The script creates the PHP bean and
injects it into the framework. After that the
framework holds a reference to the PHP bean and can
call its methods:

http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bridge/server/php/java/faces/Script.java?revision=1.6&view=markup

return
((Invocable)((PhpFacesContext)FacesContext.getCurrentInstance()).getScriptEngine(this,
new URL(script))).invoke(name, args);

I think this is exactly what you want. The only
difference is that the above method calls out to a URL
instead of a local script file.
>         String script = "var obj = new Object();
> obj.hello = function(name) 
> { print('Hello, ' + name); }";

> Any chance todo something similar with PHP?

It is certainly possible to automatically call
java_closure(), when a php object is passed to a Java
procedure. But for several reasons we've decided to
require java_closure(php_object). Furthermore, if I
understand the above code correctly, the "new
Object()" above instanciates a Java object, not an
object from the js script interpreter.

Jost Boekemeier

[Php-java-bridge-users] passing objects from PHP to JAVA

[<php...@li...>]

Sorry, once again ;-)

I wrote this little part of a Java method for testing:

PhpScriptEngine engine = new PhpScriptEngine();
String s =  "<?php \n";
s +=	"require_once 'MyClass.php'; \n";
s += "java_context()->setAttribute( 'obj', new MyClass(), 100 ); \n";
s += "java_context()->call(java_closure()); \n";
s +=	"?>";
engine.eval( new StringReader(s) );
Invocable inv = (Invocable) engine;
inv.invokeMethod( engine.get("obj"), "saySomething", new Object() );

The resulting errors are:
java.lang.NullPointerException
	at java.lang.reflect.Proxy.getInvocationHandler(Proxy.java:636)
	at php.java.script.PhpScriptEngine.invokeMethod(PhpScriptEngine.java:202)
	at Bootstrap.main(Bootstrap.java:30)
Nov 17 16:30:28 JavaBridge ERROR: PHP Warning:  Argument is not (or does not 
contain) Java object(s). in - on line 3

The NullPointerException happens in the line where invokeMethod is called.
Line 3 of the PHP script is the one where setAttribute() is called. As I 
understand the error message text, it is not possible to set a PHP object as 
an attribute to the java context, but only Java objects?

Another thing I tried was:
String s =  "<?php \n";
s +=	"require_once 'MyClass.php'; \n";
s += "$obj = new MyClass(); \n";
s += "java_context()->call(java_closure()); \n";
s +=	"?>";
but there was the same NullPointerException.

This was inspired from the Javascript example provided by SUN here:
https://java.sun.com/javase/6/docs/technotes/guides/scripting/programmer_guide/index.html#invoke

        ScriptEngineManager manager = new ScriptEngineManager();
        ScriptEngine engine = manager.getEngineByName("JavaScript");
        String script = "var obj = new Object(); obj.hello = function(name) 
{ print('Hello, ' + name); }";
        engine.eval(script);
        Invocable inv = (Invocable) engine;
        Object obj = engine.get("obj");
        inv.invokeMethod(obj, "hello", "Script Method !!" );

Any chance todo something similar with PHP?

The SwingTest.php can also be found in the server/test
folder from the source download or here:

Re: [Php-java-bridge-users] setting the runtime path

[<php...@li...>]

Hi,

[setting base directory for java libraries]

please set

extension_dir=/path/to/php/extension/dir

java_require("foo.jar;bar.jar") searches for the
foo.jar and bar.jar libraries in extension_dir/lib.

I added a comment with a simple way to solve this problem. Now I can compile
the bridge with JDK1.6 RC and run the interactive shell as well as the
HelloWorld test.

Thanks again for all your help!
