Using PHP 5.2.9 here, but function php_stream_input_read() in
php_fopen_wrapper.c is identical to the 5.2.5 one.

Before opening a bug (been there, done that) I should carefully check
what you say, but I cannot do so right now - leaving for vacation
tomorrow next and lots of loose ends to fix here at work.

Anyway I modified the Swing application to redirect the JSON-RPC call to
a "standard" Apache + mod_php 5.2.9 configuration (no Jetty no Java) and
php://input works perfectly - as well it should, since we are using that
machine as a SOAP services endpoint, consuming RAW POST data all the
time.

Will need to double check the C dode ...

Hi Massimo,

I will add a jsr223 tutorial to our web site.

The bindings are complete. The reason for the new script-api.jar was a
degression in version 5.4.4.2; I have cleaned up a little bit too much,
leaving the standalone script engine w/o a urlreader path, even though it
has been documented in the api doc. The path was re-introduced in 5.5.1.

Please see the jsr223 api documentation  for details.

The X_ headers and the java_getHeader() are internal and shouldn't be used
in general. The line I have given is an exception. You can wrap it in a
function and use 'if called_from_java() java_context()-call(java_closure())'
if you want.

> I still don't quite grasp how to use java_closure(

That's the core idea of the bridge. These calls never return but call others
ad infinitum.

Jost Boekemeier

Thank for the advice, I will try your code.
It may be me, but I would never have tried what you suggest; I can't
find documentation about the several X_JAVABRIDGE_* constants and their
intended usage, nor was I aware of the java_getHeader() function.
Moreover, I still don't quite grasp how to use java_closure() and
lastly, I believe several methods of the ScriptEngine API are still to
be implemented ... is this correct?

Hi Massimo,

You are right, when calling fopen("php://input", "r") PHP version 5 may
crash or hang. Please do not use it until this PHP5 bug is fixed.

I have looked at php 5.2.5. In php_fopen_wrapper.c line 81 it reads the
raw_post_data and then increments the SG(read_post_bytes) even though it
hasn't read anything. The result is that SG(read_post_bytes) is twice the
CONTENT_LENGTH size, causing all sorts of strage side effects later on.

In your particular case it calls SAPI.c sapi_read_post_data() which reads
the input up to CONTENT_LENGTH bytes. Then you call php_fopen_wrapper.c
php_stream_input_read() which reads nothing but increments
SG(read_post_bytes) again. And finally sapi_cgi_read_post() is called from
sapi_deactivate() to consume any remaining input. The remaining input is
calculated as (unsigned)(CONTENT_LENGTH-SG(read_post_bytes)) which is
4294967296-CONTENT_LENGTH due to an overflow.

If you post that much data, it will work, I guess... :)

Do you report this bug to the PHP maintainers?

Jost Boekemeier

I found it helps a lot to give structure and order to the

to setup and start/stop, and has a small footprint. Last but not least,
it keeps a door open for more advanced functionality I may need in the

I am currently trying to connect the Swing application with Jetty-hosted
PHP scripts via JSON-RPC, since the (RAW POST based) protocol is quite
efficient and easy to implement, both in PHP and in Java.

Sadly though, while I can readily access the RAW POST data via
php://input and can also write the JSON string received from Java to a
file, I see the fastcgi is unable to output the response ... looks like
the communication channel is corrupted somehow as soon as I fopen it for
reading.

On the grounds that I may be violating the standard way of interacting
with a servlet, I've been struggling the past few days to solve the
problem by using java_context() methods and properties, but without
success so far ... I'd appreciate some advice.

Hi Massimo,

The servlet can handle POST, but I haven't tried to open the input stream.
However, if I understand you correctly, you want to invoke PHP application
methods from a java desktop application. Sure, you could use json or even
invent your own text-based communication protocol, but why not use the php
java bridge to handle the communication?

Here's a simple php script which acts as a receiver. It waits for java
requests and invokes methods from the closed-over environment:

<?php require_once("java/Java.inc");

class MyClass {
      function hello() { return "hello"; }
      function world() { return "world"; }
}
if (java_getHeader("X_JAVABRIDGE_INCLUDE", $_SERVER))
java_context()->call(java_closure(new MyClass()));
?>

And this is the Java part, which uses the jsr223 API to call the remote
methods:
import java.io.*;
import java.net.*;
import javax.script.*;

public class JsrTest {

    public static void main(String s[]) throws Exception {
ScriptEngine e = new ScriptEngineManager().getEngineByName("php-invocable");
e.eval (new php.java.script.URLReader(new URL("http://localhost/jsrtest.php
")));
System.out.println(((Invocable)e).invokeFunction("hello", new Object[]{}));
System.out.println(((Invocable)e).invokeFunction("world", new Object[]{}));
((Closeable)e).close();
    }
}

I have tested the above code using Java.inc from
http://php-java-bridge.sourceforge.net/pjb/java/Java.inc and JavaBridge.jar
from http://php-java-bridge.sourceforge.net/pjb/java/JavaBridge.jar.

Hi,

older versions used to support unix-domain socket communication on certain
operating systems. Since version 5.4.4.2 this path is broken:

>From PROTOCOL.TXT:
*" It is possible to send the header even though the connection has
already been established. The bridge will ignore the header if the
second byte is not 0xFF."

*
However, 0xFF seems be uses to implement a short path for the
Servlet/JEE/Tomcat container now (btw: the buf[1] should really be buf[c+1],
but that doesn't matter, as c is guaranteed to be 0 at the beginning of the
communication). In order to support unix domain socket communicationn again,
we need to add a method "parseHeader()" to the IDocHandler interface, so
that we can move the code implementation below to the servlet context and
use the old code implementation from the cvs in the standalone context. Oh,
and PROTOCOL.TXT should document this properly.

  235 		case 0177: if(in_dquote) {APPEND(ch); break;}
  236 		    // the header used to be binary encoded
  238 		    bridge.out.write(0); bridge.out.flush(); // dummy write:
avoid ack delay
  239 		    int len =(0xFF&buf[c+2]) | (0xFF00&(buf[c+3]<<8));
  244 		    byte shortPathHeader = (byte) (0xFF&(buf[1]));
  245 		    if(shortPathHeader != (byte) 0xFF)  // short path: no
previous PUT request

Hi Massimo,

> I have to build a standalone, multiplatform PHP application that needs

Is it a standalone web- or desktop application? Since you mention swing, I
assume you want to write a desktop app.

I would start by writing the Java GUI skeleton and then add PHP
functionality to it, please see
http://php-java-bridge.sourceforge.net/pjb/standalone.php for an example.

*I* would write the entire application in java. PHP makes sense for
short-lived scripts, but I wouldn't use it to drive the entire desktop
application. -- I think PHP 5.3's new reference counter can reclaim certain
cycles, but I wouldn't trust it.

If you want to use PHP as a plugin only, use the JSR 223 API.

Why do you need jetty for a desktop application?

Hi Jost & all,
 
I have to build a standalone, multiplatform PHP application that needs
to use a number of java classes in both the "business" logic (e.g. the
cryptography package from Bouncy Castle) and the graphical user
interface (3rd party UI components).
 
While being proficient in PHP the same cannot be said for Java, so I've
being researching a good "hybrid" solution to get the job done and am
currently focusing on a Java Swing front-end calling a PHP-equipped
Jetty (http://jetty.mortbay.org/jetty/) on localhost.
 
Specifically, I'd like to visually create the GUI with the NetBeans IDE,
register the appropriate Event Listeners and implement all non-trivial
(or forcibly Java) event-handling code in PHP, and I am struggling to
understand strengths and weaknesses of the available options ...
following is the list of alternatives I've come up with until now:
 
1) Just make an HTTP request from the event method to a PHP script on
the Jetty back-end, where PHP can interact via PJB with any needed Java
classes or simply make use of all its built-in functionality to generate
a response. This solution implies I have to manage all response data and
interface navigation in Java; also, there won't be any continuation
passing between the Swing front-end and the PHP back-end, resulting in a
somewhat less efficient interaction;
 
2) Write Java code using JSR 223 and PJB to call PHP classes/methods on
the Jetty back-end. Still need to write Java code, nonetheless it looks
like a better solution performance-wise: problem is, to date I didn't
manage to call PHP user functions/classes from such an application - I
can run the phpversion() sample provided, but that's it. Probably my
fault, anyway I'd welcome a more complex example;
 
3) Expand the example in
http://php-java-bridge.sourceforge.net/pjb/standalone.php so the Swing
application makes HTTP calls to Jetty's PHP scripts. Instead of
returning a response like in 1), the PHP code interacts with
appropriately exposed application methods. I believe one could, to a
point, even control the interface navigation from PHP in this way.
 
Are there other alternatives to consider (I may be missing even the
simplest, most elegant solution)?
 
Regards,
Massimo

Hi,

$pageHeight and $pageWidth are java objects.

Since Java doesn't automatically convert objects into php values, you must
do this explicitly. For example with:

(int)(string)$width;

Please see the php java bridge api for other possibilities to convert
objects into values.

We managed to identify that "xdebug" plays a part.

When we enable:
zend_extension="/usr/lib/php/20060613/xdebug.so"
It triggers the Segmentation Fault.
If we disable it, it works fine.

We were using xdebug version 2.0.4. We just upgraded to 2.0.5. and the same
"Segmentation Fault" happens.

For now we will disable xdebug and contact their developers.

Could you maybe see if you can reproduce this problem on your PHP 5.2.6
deployment? To install xdebug you just need to run:
-------------------
pecl install xdebug

Could someone please post/link/email the 4.2.2 binary (not 5.4.2.2), as 
I need it for a project? Thanks in advance.

Hi,

There's a new document:

But if PJB needs Tomcat then no options are left.
If PJB can run without Tomcat let me what shall I do. I will test the pilot
application we developed without Tomcat. If it works then we can plan our
main application in different way.

Please let me know how can I make the required jasperReport jar files
available to PJB for instantiation of jasper report classes. Right now I
have
put all of then in Tomcat Lib Dir.

Thanks and best regards. Raja.

Hi,

I think a Java module system similar to SML/NJ's would be useful. The RICE
people have had a proposal for this, but it required real generics (current
Java 1.5 generics are pure syntax and not very useful).


> Is it possible to include the bridge as a Maven2 dependency?

May be. But if it requires any changes to the JavaBridge code, these changes
must be distributed separately.

Hello!

Is it possible to include the bridge as a Maven2 dependency?

As I'm managing all my projects lifecycles + dependency lookup through maven,
I would be really happy to simply add the bridge as dependency to my projects.

kind regards,

Raja,
 
The way we did it with tomcat is explained here:
http://www.theserverside.com/tt/articles/article.tss?l=IntegratingBIRTwithPHP
some additional notes are posted here:
http://www.birt-exchange.org/devshare/deploying-birt-reports/743-calling-birt-from-php/#description
 
To do it stand alone I just copied the stand alone directory to my php site and created a new directory in it with BIRT libs.  Right clicked on the JavaBridge.jar and selected the open with Java.  Then wrote php pages to access it.  Very simple.  Here was one the example pages I used.  As you will notice way to many jars.  I really did not need them all but wanted to check if this would be an issue.  With BIRT you can turn on/off pieces of the engine.  I also had some issues with the version of BIRT using static variables so I had to add a work around.  This has since been fixed.

Thanks Jason,

I also think in same direction, but since we dont have any experience in 
deploying java application
we need exact comands and directory where to place the required jars. can u 
please give us
method for how to start STANDALONE JavaBridge with which user and directory 
where to place
all required jars so that those are available for java_Require method. We 
need to test difference
between Tomcat version and Standalone method. As far as scalability is 
concerned at later dates
is there are complaints about speed or other issues we can very well switch 
back to tomcat version.
If u foresee any issues in this approach let me know.

Since already u have got Birt working without tomcat please tell me what u 
did I work on similar lines.

Thanks and best regards

Raja

Hi Andre,

Thanks. I have just re-tagged the current head (2009-07-31 10:42 UTC) as
ROOT_Release-5-5 and Release-5-5.
