Only if you access it through the servlet. Just direct
your browser to port 8080 or set up mod_jk to forward
everything to Tomcat.

Well it's quite simple. If you call 

 http://localhost:8080/JavaBridge/sessionSharing.jsp

tomcat creates a servlet from the JSP file and i
nvokes it. For PHP requests this is similar:

 http://localhost:8080/JavaBridge/sessionSharing.php

invokes a servlet which creates the HTML pages and
then delegates to PHP to fill in the content.

If you call

 http://localhost/sessionSharing.php

then Apache (or IIS) renders and returns the HTML
page.
Tomcat doesn't even see this request.

This shouldn't be a problem. Just replace the JSP
logic with PHP and you're done.

James,

The project you are working on definitely sounds like the type of =20
case study I want to see for the Web site to show other users (and =20
potential users) what can be done with PHP and Java using Jost's php/=20
Java bridge.

Contact me when you are ready to share your project results.

Re: [Php-java-bridge-users] Problems w/ java_context() under Tomcat 5.5

[<php...@li...>]

Hi,

> Am I doing something wrong when calling the
> java_context() function?

java_context() returns the current Java context. It is
a JSR223 context if JSR223 is available. A servlet
context, from which the servlet request, response, ...
can be obtained, if PHP is running within a J2EE
environment. Or a remote context when Java is accessed
through a Apache or IIS front end or from a PHP
command line binary:

<?php

require_once
   ("http://localhost:8080/JavaBridge/java/Java.inc");

$ctx = java_context();
$res = $ctx->getHttpServletResponse();
?>

In the above example $res is always null, unless the
initial request came in through the tomcat port 8080. 

What do you want to do with the ServletRequest and
ServletResponse objects anyway? When PHP is invoked
from the command line or running within Apache/IIS,
there's no servlet involved which could hold resonable
values for the HTTP "GET/PUT/POST" method or URL
parameters.


> I first tried to use
> java_context()->getHttpServletResponse
[...]
> [o(RemoteContext)]->...
> *() but that returned null.

Yes. RemoteContext always returns null for
getHttpServletResponse etc. See
http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bridge/server/php/java/servlet/RemoteContext.java?revision=1.1&view=markup


> I then tried calling
> java_context()->getAttribute

This will not work either. The JSR223 functionality is
only available if the bridge is running in a JSR223
environment:

ScriptEngineManager m = new ScriptEngineManager();
ScriptEngine e = m.getEngineByName("php-invocable");
e.eval("<?php function f($p) {return 'hi '.$p;}?>");
Invocable i = (Invocable)e;
Object o = i.invokeFunction("f", new
Object[]{"Java"});
System.out.println(o);

=> hi Java



Can you please explain what you want to do?

Jost Boekemeier

Your right it does only fire up one instance of the VM under the apache 
process, with a number of threads below that.

Thank you again.

[Php-java-bridge-users] Problems w/ java_context() under Tomcat 5.5

Am I doing something wrong when calling the java_context() function?

I first tried to use

Not really. It should start only one Java VM, attached
to the HTTP server.

It uses a thread pool. Please see our FAQ for details.
Is there a problem with this?

Re: [Php-java-bridge-users] PHP Segmentation fault after install

[<php...@li...>]

Hi,


> I am experiencing problems when trying to install

> Linux w/ PHP4 and Java5.

Please use the compiled java.so for RHEL3 instead. The
last release was 2.0.8:

http://sourceforge.net/project/downloading.php?group_id=117793&use_mirror=mesh&filename=php-java-bridge-2.0.8-1.RHEL.i386.rpm&155133



> installation, any command line
> statement is terminated with a "Segmentation fault"
> message.

This sounds as if it crashes in the MINIT function,
because all variables are set to 0. We know that some
gcc versions have (had?) a strange bug which caused
this. It is (was) probably a bug in the optimizer: -O0
fixes this, so does a reboot(!) and recompilation.
Someone has reported this on FreeBSD and sent us the
java.so created before and after the reboot. In the
first java.so the init section was missing.

Can you please open a problem report and attach the
created java.so at the end of this ticket?

Please also report the gcc version and the conditions
when this problem appears and the hardware you use.

Jost Boekemeier

[Php-java-bridge-users] PHP Segmentation fault after install

[<php...@li...>]

Hi,
I am experiencing problems when trying to install the bridge on Red Hat EL
Linux w/ PHP4 and Java5.
Dowloaded the latest source archive (v 3.2.1-1), successfully compiled and
installed the bridge as superuser (no compilation or installation errors).
However, this seems to break my current PHP installation, any command line
statement is terminated with a "Segmentation fault" message.
For example:

[root@db php.d]# php
Segmentation fault

Commenting out the "extension = java.so" declaration in java.ini fixes PHP
again, so I conclude it must be a problem with the bridge:

[root@db php.d]# php --version
PHP 4.3.9 (cgi) (built: Nov  2 2006 16:39:38)
Copyright (c) 1997-2004 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies

FYI, I am running on:
Red Hat Enterprise Linux ES Release 4
PHP 4.3.9
Apache/2.0.52
Java 1.5.0_10 with Tomcat 5.5.20

Did anyone experience similar issues? Please help!
Many thanks,
-Stefan

Hi James,

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.

[Php-java-bridge-users] FYI: PHP/Java Bridge 3.2.1 released

[<php...@li...>]

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

Hi JJ,

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:
http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bridge/java_bridge.c?r1=1.47&r2=1.48&sortby=date

Re: [Php-java-bridge-users] coredump on running the CVS with php5 and sunjava

[<php...@li...>]

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.

Jost Boekemeier

[Php-java-bridge-users] accessing a headless component

[<php...@li...>]

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

[Php-java-bridge-users] PHP5.2.0 not install.

[<php...@li...>]

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.

Re: [Php-java-bridge-users] coredump on running the CVS with php5 and sunjava

[<php...@li...>]

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?

Re: [Php-java-bridge-users] Windows setup problems

Hi Peter,


> 3.0.7 (we use 3.0.8), loading libraries from a

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.

Re: [Php-java-bridge-users] coredump on running the CVS with php5 and sunjava

[<php...@li...>]

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.


Regards,
Jost Boekemeier

Re: [Php-java-bridge-users] 3.0.7a compile from source problem

[<php...@li...>]

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. :)
