This is neither documented nor recommended. It is only used to create a clean environment
during the feature tests.

java_reset() already displays a warning message. I think we should throw an non-catchable error
in the next release if it is used outside of a test environment.

sort of. The cache algorithm applies before the dynamic proxy proxy is resolved; 
the cache sees a ProcedureProxy, not a DynamicProxy.

Yes. However, I have attached a patch which solves this problem.

Thank you very much for reporting this issue!

Just a quick question -- you do recommend using
java_reset() after our PHP script is done calling Java
code, so as to release memory (for use by other
processes)?

Hi again, Jost!

Just so you know, I still haven't tried out your
suggestion to save the log and send it to you.  

Off the top of my head, it might have to do with the
fact that there is a third-party application
(MediaWiki) taking up memory that slows down PHP-Java
bridge code.  

I'll keep you posted.

the bridge  caches the first istance of Obj that i create without any
particular interface, and when i try to create a new istance of Obj
with IVisit interface, the bridge uses the cached version anyhow. Is
it right?
then, if i create the first istance with all the interfaces i need, i
should have no caching problem. right?
if i'm right, i don't need a new version.

maybe, it would be nice to compare the proxy passed as argument and
the cached one
checking their interfaces too (i suppose  the bridge checks the class only)


thank you a lot for paying me attention!

my best greeetings

Hi,

> are you sure that you call the right code?

it's the cache problem I've mentioned before.  Is that really a problem in practice?
If so, I could prepare a version 3.2.1b, which switches off the cache when one of the arguments
is a proxy for a dynamic proxy.

Hi,


> Guys, I'm having serious memory leaking problems and I want to make sure I
> have PHP/Java Brigde properly configured and that I'm using it correctly.

can you please be more specific?  Memory leaks in the back end or in PHP?

The old C implementation[1] does have some memory leaks. But this isn't a problem since the 
Zend memory manager takes care of them. 

If there are memory leaks in the back end, please see our FAQ how to debug
memory leaks in your code.


Regards,
Jost Boekemeier

[1] The C implementation prior to 4.1.8. Since 4.1.8 the C implementation simply
compiles the pure PHP implementation into obcode and uses that.

Hi,

are you sure that you call the right code?

According to your log java_get_closure() is called with only one argument:

> Jul 28 01:41:50 JavaBridge DEBUG: 32fb4f@10b9d04 --> <I v="0"
> m="makeClosure" p="I" >
> Jul 28 01:41:50 JavaBridge DEBUG: 32fb4f@10b9d04 --> <L v="1" p="O" />
> Jul 28 01:41:50 JavaBridge DEBUG: 32fb4f@10b9d04 --> </I>

Since the bridge doesn't have any information about the type, "Object" is assumed.

Hi Jörg,

You don't need a dll. The PHP/Java Bridge is written in pure PHP and pure Java. 
Please see the README for details.

Only PHP 4 needs such a dll, because it implements certain features 
which were not available in PHP 4 and earlier versions.

i have only one:
<?php
require_once("http://localhost:8080/JavaBridge/java/Java.inc");
java_require("/var/www/prove");

$o = new Obj();
$o->exec();

class Obj
{
	var $a = 'pluto';
	
	function __construct(){ $this->a='paperina';}
	
	function exec()
	{	
		try {
			$obj = new Java('ObjPassing');
			$a = java_Cast($obj->testMe(),'string');
		
			$obj->visit(java_get_closure(new Obj()));
			$obj->visit2(java_get_closure(new Obj()));
			
			$obj->visit(java_get_closure($this));
			
			$obj->visit(java_get_closure(new Obj(),null, new JavaClass("IVisit")));
			
		}
		catch(JavaException $ex)
		{
			$exStr = java_cast($ex, "string");
   			echo "\nException occured; mixed trace: $exStr\n";
		}
	}
	
	public function eccolo() { }
}
// suppress the warning message from the use of reset.
@java_reset();

?>

PS: even if i don't know why, i've noticed that i manage to call the
rigth method if the exec method of my class is only:
function exec()
{	
	try {
	  $obj = new Java('ObjPassing');
			
	   $obj->visit(java_get_closure(new Obj(),null, new JavaClass("IVisit")));
			
	}
	catch(JavaException $ex)
	{
		$exStr = java_cast($ex, "string");
		echo "\nException occured; mixed trace: $exStr\n";
	}
}

If I wanted to use the Pure PHP Implementation I would need to install

Guys, I'm having serious memory leaking problems and I want to make sure I
have PHP/Java Brigde properly configured and that I'm using it correctly.

I have just activated the PHP/Java Bridge log in debug mode. I would
appreciate any help you can provide to help me on the troubleshooting.

If anyone can provide an MSN Messenger, YIM or GTalk contact so that we can
work live would be a great help.

Thanks,

Hi Jost,

thanks for all your answers. I follow your last answer and i delete the 
php.ini in the cgi folder. The same behavior. Then i upgrade the bridge 
from 3.2.1a to 4.2.1. But unfortunately i cant find the 
java-x86-windows.dll for copy into the php/ext folder. Then i take the 
php-4-java-x86-windows.dll and renamed it to php_java.dll. This is not 
working. I am afraid it is incorrect what i done.
ok.

i dont know it is the best way. I see the php-webapp running in my 
apache.  i see also a call into java. I thought, wow it is great.
I'm afraid i need now help from professionals. I dont know it is ok i 
ask in this forum - Can you help me as professional-consultant to solve 
the problem?

regards Jörg

Hi Jörg,

> unfortunately runs the php-app not in the tomcat

then you'll need to use the JSR223 interface to call your PHP scripts running in the web server.
This will not necessarily slower than a PHP FastCGI server attached to the web context, but
certainly much more inconvenient as it requires an external web server and
that the web server is configured to run PHP.

PHP > 5.2 now prefers the php.ini from the current ("cgi") folder over the system php.ini. 

Please remove this file from the cgi folder.


Version 4.2.1 and above change the current working directory when the 
system php executable is used to avoid this problem.

The php version they used issnt the same as i installed. I installed 
5.2.3 in C:\Programs\PHP\php. If i run php-info i see that 
C:\Programs\PHP\php.ini is used, but the version is 5.1.3-dev I think 
the version they be used is located in the cgi folder!?
But  some librarys can`t  loaded: may logfile:
PHP Warning:  PHP Startup: Unable to load dynamic library 
'C:\Programs\PHP\ext\php_imagick.dll' - Die angegebene Prozedur wurde 
nicht gefunden.
This dll is present and the folder is correct. (It works without the bridge)

What is the reason?

Hi Jost!

I got your message about sending you the debug log.  I
was kind of tied up today (and maybe tomorrow).
Hopefully, I can send you the log by Monday at the
latest.  

Btw, I forgot to tell you, I'm using an external
application (MediaWiki).  This calls a PHP script that
calls Java code.

Here is a rough time profile:

1) MediaWiki loads a new article (no PHP script)
   - 0 to 2 seconds
2) MediaWiki loads article that contains PHP script
that calls Java code using PHP-Java Bridge
   a) For the first time - 12 to 18 seconds         
   b) Succeeding times - 1 to 4 seconds 
      (not 5 seconds as I reported to you last time)

Meantime, could you point me out to websites that
explain how Apache and PHP work together, and also the
Java VM, so I can better understanding of PHP-Java
Bridge?  

Thanks!

Filip

this is a great idea. i think this could be the solution. The 
prerequisite is that the php-webapp is correct running via the bridge in 
the tomcat. unfortunately runs the php-app not in the tomcat. I reduced 
my system to the absolutly mimimum. I installed php version 5.2.3. If i 
configure the system as you decribe in
PHP5, PHP/Java Bridge & Apache on XP PRO + SP2 and examples 
(http://www.dsl.uow.edu.au/~sk33/php5java.htm)
the Bridge is running and if i call phpinfo then i see the correct 
version 5.2.3
If i configure as PHP5, PHP/Java Bridge & Tomcat on XP PRO + SP and 
examples (http://www.dsl.uow.edu.au/~sk33/php5jsp.htm)
the bridge isnt running. In this case, i wondering the the php version 
is 5.1.3-dev. why used this install not the installed version?

A question to you, it is posible to get you as consultand to solve this 
case in our project?

Hi Jörg,

first of all thank you very much for your feedback.

I assumed that you wanted to connect your framework (typo3) with another,
java-based framework running in a different web context, but within the same
tomcat container.

1) So you have typo3 running in the Apache front-end connected to an associated back-end 
running in tomcat. 

2) A second, unspecified application is running in tomcat, associated with the Apache 
front-end via mod_jk.


The second application should parse the request parameters and call the first application which
should generate the response.

Isn't it possible to direct all requests to the second app and then use
requestDispatcher.forward(...) to let typo 3 generate the response?

The call graph would be:

 apache --mod_jk-> tomcat app#2 --forward-> php/java bridge -> response

Hi Philip,

>    I don't use CGI.  Does that automatically mean my Apache can maintain a pool of instances?

yes. Some other component must cause the delay.  Do you load the Java libraries from a shared 
network folder so that the dynamic classloader doesn't cache the libraries?

Can you please set the log level to 5, open a problem report (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233) and append the log at the
end of the ticket?

We'll look at this issue asap.

i dont know exacly what you mean with another web application. I have a 
Apache / Tomcat (mod_jk). First webapp is a pure php-system (typo3 cms). 
The requests is not forwarding via mod_jk to the tomcat. In this webapp 
i install the bridge (WebInf Folder and java folder from the

This method retrieve the parameters and use it. But the response is

Hi Jost!

Sorry, I forgot to give you information about my environment: 

32-bit Intel Machine
Windows XP + Service Pack 2  
WAMP Version 1.6.5 which includes:
   * Apache 2.0.59
   * PHP 5.1.6 (Using Apache 2.0 Handler as Server API)
JDK 1.5.0.10
PHP-Java Bridge 3.2.1 J2EE

> I assume you mean the DynamicClassLoader. (DynamicLoad may also mean > that you start the bridge and the JVM as a sub component for each incoming
> request).

Yes, I meant the DynamicClassLoader.  

> Do you start Java as a sub component of apache or IIS or as a separate
> component, for example via the Tomcat servlet engine?

I installed PHP-Java Bridge following instructions here:

   TITLE: PHP5, PHP/Java Bridge & Apache on XP PRO + SP2 and examples
   URL: http://www.dsl.uow.edu.au/~sk33/php5java.htm

In that setup, I suppose I start Java as a sub component of Apache (?).

>> 3) The system loads the Java Virtual Machine (JVM). 

> Only if the JVM is running as a sub component of Apache ... AND if Apache ... > cannot maintain a pool of PHP instances, which is usually the case with CGI. 
> (emphasis mine -- Filip)

You mention two conditions:

   1) the JVM is running as a sub component of Apache

   The answer appears to be YES.

   2) Apache cannot maintain a pool of PHP instances, which is usually the case with CGI

   I don't use CGI.  Does that automatically mean my Apache can maintain a pool of instances?

   If that is the case (i.e. the second condition is not met), then the system SHOULD NOT be loading the JVM every time a user requests for a PHP script.

>> 4) The system loads all Java libraries needed by the PHP script.

> Only if the JVM is running as a sub component OR Apache/IIS and PHP is 
> running in CGI mode. (emphasis mine -- Filip)    

Only if the JVM is running as a sub component --- TRUE
Apache/IIS and PHP is running in CGI mode --- FALSE

TRUE or FALSE = TRUE, the system does load all Java libraries needed (e.g. log4j, dom4j, etc.) per request unless they're already in the cache (?)

>> What happens exactly with "static loading"? Is this sequence of events accurate?
>>

So do you think this is the solution to my problem (slow loading per request, esp. the first)?

> The only exception are CGI or console scripts. 

By 'console scripts', do you mean command line scripting (that doesn't use a web server)? 

Thanks again!

Hi,

> DYNAMIC LOAD method.  

I assume you mean the DynamicClassLoader. (DynamicLoad may also mean that you start the bridge
and the JVM as a sub component for each incoming request).


> It works but the web page that contains the PHP script loads very slowly
> (15-20 seconds) the first time, but a bit faster the succeeding times (5 seconds).

5 seconds is too slow. This may mean that you are starting a new JVM for each invocation.

Do you start Java as a sub component of apache or IIS or as a separate component, for example
via the Tomcat servlet engine?

> What the Java code does is supposedly simple, it reads a short string value from a relational
> database, and passes it to PHP script to display.  Oh, but the Java code requires a lot of
> libraries like log4j, dom4j, asm, xom, etc. (more than 20 of them).

Does't matter, the DynamicClassLoader caches them.

>   What happens exactly with "dynamic loading"?  Is the sequence of events below accurate?

[depends on what you mean with "dynamic loading".

>   1) User requests for a web page that contains a PHP script that calls Java code.

Apache/IIS keeps a pool of PHP instances. When the client browser requests a PHP page, the
web server activates the PHP instance and passes it the script. The PHP/Java Bridge creates
an XML document from the script and forwards it to the Java VM (usually started via a local
Servlet Engine).

>   2) The system loads all Java base classes (libraries).

When your script contains a java_require(...) call, the DynamicClassLoader resolves and loads
the Java libraries and caches them.


>   3) The system loads the Java Virtual Machine (JVM). 

Only if the JVM is running as a sub component of Apache or IIS and if Apache or IIS cannot
maintain a pool of PHP instances, which is usually the case with CGI. 


>   4) The system loads all Java libraries needed by the PHP script.

Only if the JVM is running as a sub component or Apache/IIS and PHP is running in CGI mode.


>   What happens exactly with "static loading"?  Is this sequence of events accurate?
> 
>   0) User starts up the welcome page of a web application. 
>       The system loads all Java base classes (libraries) AND 
>        the Java Virtual Machine (JVM).

Well, the JVM is usually started as a separate component. Or in the MINIT method invoked during
the startup of Apache or IIS. This means that one VM is usually attached to the web server.

The only exception are CGI or console scripts. If you use the C implementation, it will start
a new JVM for each invocation. If you use the PHP implementation, it will throw an error if no
persistent JVM is running on the given port#.
