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

Hello,
I uploaded php-java-bridge Debian 4.0 package files to the project "Files" area.
The needed source files for building your own Debian package were uploaded too.
Please, read the release notes at the site.
Please, send packaging suggestions and corrections.

AFAIK there is no "php_java.dll" file packaged with
PHP 5.2.0. The last supported version was 4.2.x, see

http://pear.php.net/bugs/bug.php?id=7679

and the documentation that's part of the PHP download.

Yes. But this shouldn't be an issue. Even in the worst
case (one round-trip for each statement) our pure PHP
implementation is still faster than a comm. via SOAP.
Furthermore this issue only exists with the C based
PHP
version. The Java based PHP version can (and does) 
optimize the code through the JIT.

But back to the documentation issue; 
I think the real problem are the users who blindly
download a compiled php_java.dll from
http://pecl4win.php.net/ext.php/php_java.dll and 
expect that it somehow works; without looking at 
the documentation.

More (i.e. redundant) documentation doesn't help imho,

users won't read it anyway.

Jost Boekemeier

The project team is pleased to announce a new and snazzy Web site for  
the php/Java bridge project.

         http://php-java-bridge.sourceforge.net/pjb/index.php

The new Web site features better organization of all of the work Jost  
has compiled over the years and will include some new sections to  
highlight examples of using the bridge, case studies from our user  
community, and upcoming platform-specific installation guides.

If you are currently using the php/Java bridge in a production  
environment at your business or educational institution, and would  
like to have your project featured on the Web site send me an email.   
It's a great way to share with others in the community how you have  
used Open Source to solve real-world challenges.

Please send any Web site feedback you have, including typos, bad  
links, and suggested new content, to jon...@us....

As with all open-source projects, your input and participation is  
what makes the community work. Please help us by participating in the  
user discussion forums/mailing list and become a supporter.

Hi,

PHP/Java Bridge version 3.2.1 is now available.

It contains only bug fixes for problems reported since
the 3.1.8 release.  Please see 

  http://php-java-bridge.sourceforge.net/NEWS

and

  http://php-java-bridge.sourceforge.net/ChangeLog


for details.

The protocol hasn't changed (and it will not be
changed in future releases), so that ver. 3.1.8
clients can be used with a 3.2.1 server and vice
versa.


Regards,
Jost Boekemeier

This fix should only be necessary for the worker MPM,
which has been disregarded by the PHP folks (due to
security issues probably). On productions systems
please use the prefork MPM instead; see the INSTALL
document for details.


> Is it such a correction and isn't there problem?

Thank you very much for the bug report! 
Fixed in CVS head:

Hi Vivek,

interesting.  Can you please open a problem report
(please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)

and attach the created java.so, the core dump and an
strace (if possible) there?

A trace can be obtained with e.g.:

strace -s 1024 php test.php 2>php-java-bridge.trace


> It would be great to see the bridge shipped as a

Debian packages will be available with php-java-bridge
version 3.2.1, which will be released soon. Until then
please use the binary from the FC5 RPM, please see the
FAQ (on php-java-bridge.sf.net) for details.


Regards,
Jost Boekemeier

Hi,

How can I access a headless java component running in JBOSS using
php-java-bridge. PHP and Java are running on different servers. Is it
possible to use the java component in jboss from a remote server through a
php script.

Thanks & Regards
Vamsi

Hi.

It was possible to compile it by changing "zend_exception_get_default()" 
of source to "zend_exception_get_default(TSRMLS_C)". 
Is it such a correction and isn't there problem?

distributions do not still ship php 5.2.0 until then please support the 
older versions. It would be great to see the bridge shipped as a 
package. esp debian package.

http://php-java-bridge.sourceforge.net/java/README says
"WARNING: THIS IMPLEMENTATION IS 10 TIMES SLOWER THAN THE C
IMPLEMENTATION"
Does it still holds for the "PHP 5.2.0 and the pure PHP/Java Bridge 
implementation"?
If so, then why is the C extension "obsolete" or why the decision to 
abandon it?

out of curiosity; why doesn't it work and where is
that documented?

Since 3.0.8 the extension_dir\lib is no longer scanned
by the dynamic loader, but the static loader should
have loaded the jar files during VM startup.

Hi Vivek,

> test core dumps.

my crystal ball tells me that you use PHP/Java Bridge
version 3.2.1 on Linux, upgraded from 3.1.8 via "cvs
update". :) When doing a "cvs update" please make sure
to rebuild the sources from the templates (the .in
files).  The scripts don't do this automatically,
without a "make distclean && rm -rf autom4te.cache"
you will get a mix of old and new code.

Can you please open a problem report (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
and append the following information:

* the OS

* the PHP/Java Bridge version (whether from CVS or
tarball)

* the PHP version

* the config.log and config.status


As a workaround please use PHP 5.2.0 and the pure
PHP/Java Bridge implementation instead. -- In future
versions we will remove the obsolete C extension
module from the J2EE download, and leave it to the
distributors to create a customized or optimized
extension for specific PHP versions.

Jost Boekemeier

I have compiled the bridge with php5 and sun java without problems . but 
on inserting it into php.ini both apache and the comand line test core 
dumps.

I can help you with debug. if you can let me know how to get them.

Hi,
   
  you can't compile php-java-bridge-3.0.7a against the new 20060613 API. I think that's why Jon suggested to use php-java-bridge-3.1.8 instead. :)

Yes i can use the pure php version, but the native one is much faster.

Hello,
how can i access a public static method, from a public abstract class =
from my PHP code? I'm trying to access the ApplicationContext from =
Spring Framework, to get access to messages...

public abstract class WebApplicationContextUtils {..
public static WebApplicationContext =
getWebApplicationContext(ServletContext sc)=20
...
}

This - below - is generating errors:

$wu =3D new =
javaClass("org.springframework.web.context.support.WebApplicationContextU=
tils");
$sc =3D java_get_context()->getServletContext();
$ac =3D $wu->getRequiredWebApplicationContext($sc);

Thanks,

I'm working with php-java-bridge-3.0.7a_j2ee on Windows XP with jdk1.5.0_10=

I have tried factoring the cmd into parts.
phpize seems to work.
the configure command produces many very similar blocks like this:

cd . && /bin/sh ./config.status Makefile depfiles
config.status: creating Makefile
config.status: executing depfiles commands
make[2]: *** No rule to make target `ltmain.sh'.  Stop.
checking for ANSI C header files... (cached) yes
checking....
.
.
with the checking statements continuing. Is this a problem? The command
completes with no summary error.

the 3rd and final command, make, quickly bails with the error on its  
first compile attempt (java.c):

WOW!

I just figured out my problem.

In my exception handler i was doing this:

System.out.println( "Exception: " + e.getMessage());
System.exit(0);

I was closing things down myself!

Thanks anyway!

Hello,
I tried to generate a debian package from cvs tree, but it fails to compile
even from "normal" compilation.
It keeps recursively adding compiler flags until being manual abort.

./configure --with-java=/usr/lib/jvm/java-1.5.0-sun
--prefix=/home/temp/temp_sourceforge/php-java-bridge-3.2.1/debian/php-java-bridge

make

Please see the partial build log at
http://paste.debian.net/17835
 (expires Thu 7th Dec 13:22)

It seems do not having server makefile...

See the aborted build log at
http://paste.debian.net/17836
 (expires Thu 7th Dec 13:31)


Also, if one have any debian control files suggestions sent at a previous
message, please send to the list.
regards.
