Hi,

I have updated the examples page. I think this

=> http://php-java-bridge.sourceforge.net/pjb/examples/source.php?source=PhpThreads.java

is what you want.

Hi André,

I think the issue was that java/Java.inc was missing in the PHP include path. See my other message.



Regards,
Jost Boekemeier



      

Hi André,

okay, I will comment out the java.security_policy=On in the java.ini.

BTW: Which Java VM is it? The "policy==" syntax is valid (http://java.sun.com/j2se/1.4.2/docs/guide/security/PolicyFiles.html), but some JVM implementations (GNU Java?) may not recognize it.


> The "Djava.security.policy==" issue was commited
> at bind.c v1.92 [0]

It happened when I switched on the policy in the java.ini file:

-----------
        * VERSION, php-java-bridge.spec: Version 5.2.2.3 released

2008-09-21  Jost Boekemeier  <jostb@intern>

	* java.ini: Use a very restrictive security setting.
-----------



> I will adapt the packaging to include the Java.inc and
> JavaRaw.inc files.

Java.inc is everything PHP users really need. Java users who want to call PHP libraries from Java also need the JavaProxy.php within the PHP web application. I would simply install the entire java/ folder into the PEAR include path (/usr/share/pear?). (http://php-java-bridge.sourceforge.net/pjb/docs/php-api/ric_README.html)


> What about the "jce.jar" issue?

I think it's a misunderstanding. Unlike other VM implementations Java doesn't have a "GAC", a single repository for Java packages. GNU used to use /usr/share/java, Sun introduced /usr/java/packages/lib/ext in Java 1.6. java_require() searches both locations, then $HOME/lib and then PHP_INCLUDE_PATH/libname/libname.jar.

I think we should sidestep these Java class loading issues by always requiring a Tomcat back end. -- This would automatically eliminate the java.security.policy issue mentioned above and probably other (GNU-/Kaffe-/...) JVM releated issues; the Tomcat maintainers have much more experience with the different JVM implementations than we have.

Unfortunately I can't nuke the java.so and require a Tomcat back end because of *BSD kernel issues[1]. But for Debian/Ubuntu it may be a viable alternative, I think.

Jan Wagner ( waja AT cyconet.org) bring to attention some problems.
The "Djava.security.policy==" issue was commited at bind.c v1.92 [0]
The cvs log message does not contain the reason.
Could it be reverted to "Djava.security.policy=" without side effects?

Hello,

thank you for your answer.

My script doesn't use Java, but the PEAR package "XML/fo2pdf.php" does.

The script exited after running:
$options = @new Java("org.apache.fop.apps.CommandLineOptions", $options)
(from fo2pdf.php)

As Patrick said, FOP 0.95 is not compatible with "XML/fo2pdf.php",
therefore I should hack this package or will use the Apache FOP 
embedding Fop2PDF.java from:

http://xmlgraphics.apache.org/fop/0.94/embedding.html#ExampleFO2PDF

Apache FOP is a Java library which converts XSL-FO to PDF; it is invoked 
via the Java Bridge from PHP.

I run a system (on FreeBSD, but platform doesn't matter) which uses PHP 
5.2 and Java Bridge 4.0.8a to call FOP 0.20.5. We don't use the PEAR 
library XML_fo2pdf like you do, but the code is very simple and thus 
similar.

I've attempted to use FOP 0.95, but in short, FOP broke compatibility 
between 0.20.x and 0.95. We continue to use 0.20.5 in production simply 
because it works and there's no need to upgrade. Considering that 
XML_fo2pdf is out of maintenance by about five years [1], odds are it 
just doesn't work with FOP 0.95.

If you have any true need for FOP 0.95 over 0.20.x, you will need to 
hack XML_fo2pdf. If you do take the time, I'd suggest posting your patch 
to the PEAR website when you're finished.

Cheers,
Patrick van Staveren

I can edit the PEAR include path in php.ini. But what is the path to
be included?

What do you mean with this? Your script doesn't even use java() statements, so how can this be a PHP/Java Bridge problem?

Hello,

I've installed PHP-Java-Bridge 5.2.2
and would like to create a PDF file using FOP and PHP.
OS: Solaris 10
FOP: version 0.95
PHP: version 5.2.6
Java: jdk1.6.0
Apache: Server Version: Apache/2.2.9

when I run fop form the command line, the PDF file was created.
./fop test.fo test.pdf

But when I created a PHP file, let's say mytest.php as following:
---------------------------
<?php
 
include_once ("XML/fo2pdf.php");
 

 
$pdf = new XML_fo2pdf( );
 
$pdf->tmpdir = "/tmp";
 
$pdf->run("/tmp/simple.fo", "/tmp/simple.pdf");
 
$pdf->printPDF();
 
$pdf->deletePDF();
?>
---------------------------

I could not see any PDF file in my browser after checking the PHP page
http://my-server/mytest.php

The script exit after executing $pdf->run("/tmp/simple.fo", "/tmp/simple.pdf");
without any errors or warning (I've checked the apache log file, php-java-bridge.log file,phperror logfile)


I have tried the runFromFile and runFromString (in fo2pdf.php) methods they behave the same way.

My question is : is PHP-Java-Bridge 5.2.2 working with FOP 0.95 and PHP 5.2.6, Java_1.6.0 ?
Any help would be appreciated.

BTW, the same script (PHP) is working with:
FOP: 0.20.4, PHP-Java-Bridge-4.0.8a, Java jdk1.5.0_06 (I mean the PDF file has been created).

Hi again,

sorry for the misunderstanding.

> I'll need to use php classes in java to escape rewriting for now.

JSR 223 examples can be found here: https://scripting.dev.java.net/

A specific JSR 223 example is here: http://php-java-bridge.sourceforge.net/pjb/examples/php%2Bjsp/source.php?source=script_api.php -- The example is written in PHP which in turn accesses Java, which in turn accesses PHP through the JSR 223 API, which in turn accesses PHP by invoking java.lang.Thread.run() method, which in turn is backed by a PHP run() implementation; essentially running 5 PHP threads from Java, concurrently writing to a shared output device.

Hi Andrè,

is it possible to install a Java.inc into the PEAR include path on debian?


Regards,
Jost Boekemeier





      

Hi,


> I'd like to peruse the PHP classes generated by

> can I find these files?

they are generated "on the fly" by the PHP standard library. The generated classes are just tags which extend the generic "Java" class; they don't have any features of their own.


Regards,
Jost Boekemeier



      

I'd like to peruse the PHP classes generated by java_autoload. Where
can I find these files?

I get the following error when I did what you suggested:

Fatal error: require_once() [function.require]: Failed opening
required 'java/Java.inc' (include_path='.:/usr/share/php:/usr/share/pear') in
/home/kratib/www/d6/sites/all/modules/sheetnode/sheetnode_xls.import.inc
on line 20

Should the include_path look different than this?

You can find examples in the JSR 223 API documentation.


      

Hi,

static final values do not exist. I guess you mean final class features.

They can be accessed as usual, provided that they are accessible:

java_autoload("foo.jar;bar.jar");
use com.FooClass as BAZ;

echo BAZ::type()->VERSION;



Regards,
Jost Boekemeier



      

Hi,

the java/Java.inc should be in PHP's include path.

require_once("java/Java.inc")

should be sufficient.


Regards,
Jost Boekemeier



      

Hi,


> he is not finding EngineFactory, nor even in the import
> path.

who is he? :) The EngineFactory is in the php-servlet.jar, the standalone jsr 223 classes don't need it and don't reference it.

Try to run java with the -verbose option to see which component references the missing class.


Regards,
Jost Boekemeier





      

I can't find the way to access static final attributes of a Java class
through PHP. Can anyone tell me the syntax to do so? I use java_autoload
to load the required jars.

TIA,
Karim

Sorry for posting yet another n00b question, but I really searched in
vain through the documentation and the Web for answers.

I installed php-java-bridge_5.3.2.1.2-1_i386.deb on Ubuntu 8.10.
Installation went fine and now the following process runs every time
Apache starts:

java -Djava.library.path=/usr/lib/php5/20060613+lfs
-Djava.class.path=/usr/lib/php5/20060613+lfs/JavaBridge.jar
-Djava.security.policy==/usr/lib/php5/20060613+lfs/javabridge.policy
-Dphp.java.bridge.base=/usr/lib/php5/20060613+lfs
php.java.bridge.Standalone LOCAL:@java-bridge-47fa
3 /var/log/php-java-bridge.log

Now I'm trying to use the bridge from PHP, but I don't know how to
access Java.inc, which is stored inside JavaBridge.rar. Is the process
above exposing a Web listener that I can access? I tried playing with
the java.ini file, setting java.socketname, java.servlet and java.hosts
but the process above only runs if I use the default ini settings. As a
workaround, I extracted the Java.inc file from the JavaBridge.jar file
and included it explicitly. My code worked fine then.

I'd like to keep using standalone mode, but without having to extract
the needed .inc files. How to do that?

TIA,
Karim

Hello,

I have a project that require java interpreter.

But I've made some part of the project in php.

I'll need to use php classes in java to escape rewriting for now.

It's difficult to find exemple of php code call from java.

The simple code on the web site does not work on my machine telling that 
he is not finding EngineFactory, nor even in the import path.

I do not need apache or web tools, just being able to run php command 
line script in java and being able to use php objects.

Thanks in advance for your help.

David
