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

Hi André,

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

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

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.
-----------

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.

Hello,
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?

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

What about the "jce.jar" issue?

Regards.
Andre Felipe

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

cheers,

Al

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
