Hi Anthony,

yes, 5.1.x rejects the php_java.dll because the
windows dll was compiled against the 5.0.x series. You
should find the reason in the (apache or IIS) HTTP
log.

Please either use a php 5.0.x version or, if you know
how to compile the dll on windows, you can also
compile it against 5.1.x or 6.x yourself. A
php_java.dll compiled against 5.1.x can also be found
here: 

 
http://php-java-bridge.sourceforge.net/snaps/php-java-bridge_3.0.6.zip

According to the log you've attached, the php module
was able to contact the backend run the test.php at
least once; probably when you've used the php5.0.x
version that comes with the php-java-bridge-3.0.6
download.


The next version 3.0.7 will ship with two php_java.dll
binaries, one for 5.0.x and one for 5.1.x.  

I think this is not the final solution; if one patchs
the ABI header, the java extension works with all php
versions, from 5.0 to 6.0 (at least on Linux). But php
module loader always rejects the dll if the PHP and
module ABI versions do not match *exactly*. It might
be possible to use the zend module loader instead,
this loader can load modules without excessively
checking the ABI version.

I will check this for version 3.0.7 or 3.0.8, see
PR1420806
(http://sourceforge.net/tracker/index.php?func=detail&aid=1420806&group_id=117793&atid=679233).
 

Until then please either use php5.0.x or the 3.0.6
snapshot with the php5.1 binary.


If this doesn't solve the problem, please open a bug
report, please use:

The problem is even I have used LoadModule mode or CGI mode for PHP 5.1.2,
it failed in either case:

For LoadModule case:
* I could be successful to start the standalone JavaBridge.jar but, in
test.php, dl() cannot be run and display error ( I am confused with your
explanation that the error is wrong),.

For CGI configuration:
* The JavaBridge.jar could be started and result.html shows it is running.
However, when  I test it with test.php, this time, there is no error from
dl() function but, it displayed my Java server IS NOT running from the
phpinfo(). At the bottom of the page, it complained that I have not put
the .dll properly. Afterwards, I have read through the code and
java_get_server_name() failed in the if-then block.

Please advise for my problem. Thank you.

Anthony

Hi,

> I have tried to run PHPJavaBridge on Apache 1.3.X
and PHP 5.1.2.

the zip file from
http://php-java-bridge.sourceforge.net/snaps/php-java-bridge_3.0.6.zip
should solve this php ABI problem, please see 
http://sourceforge.net/mailarchive/forum.php?thread_id=9495948&forum_id=42415
("Re: Anyone have a compiled php_java.dll for
php5.1.1") for details.

The error message "dl() [function.dl]: Not
supported..." is wrong, of course. The test.php should
display the original error message.

I will change the test.php for the next version 3.0.7.



Thank you very much for this bug report!

Thanks! That zip file fixed my dll issue.

I have to use a secure transcation engine (VEserver) shipped as "DebiTechSe=
rver.jar". All our sites are written in PHP. I have tried different solutio=
ns from README / INSTALL with no success. Recompile PHP isn't an option (ra=
ther swicthing OS instead). This is my last resort... See if any can come u=
p with an answer.


Setup:
* Debian "sarge" (kernel 2.4.27-2-686-smp)
* Apache2 2.0.55
* PHP 5.0.5
* Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
* PHP/JavaBridge 3.0.6


What I've done:
* Downloaded php-java-bridge-3.0.6-1.FC4.i386.rpm and extracted all files t=
o a temp dir.
* Copied java.so, JavaBridge.jar and libnatcJavaBridge.so (?) to /usr/lib/p=

Hi,

I have been looking forward to be able to use the Java bridge you
provide as a replacement for the ext, but it appears that all Windows
binaries provided are only for PHP5 (5.0.x binary as noted in the
INSTALL.WINDOWS file). Is there any way to get this running for PHP4?
I tried several of your 2.0.x distributions ... I have no need at this
point to switch to PHP5 and the production system is PHP4 (and
probably will be for a while)

--TJ

Hi,

the PHP/Java Bridge 3.0.7 will contain a php5.1/php6
php_java.dll in the j2ee download (the separate
windows download will vanish).

> Apparently, bridge 3.0.5 has a dll that only works
for 
> php 5.0.x for windows.

The PHP code refuses to load the dll because it thinks
the ABI is too old.  At least for the PHP/Java Bridge
module this sanity check is obsolete; the bridge only
uses stable official API's and it never ever accesses
globals directly (due to a limitation in our
cross-compiler: if it has to access global vars, it
calls zend_eval_string(code), that's a little bit
slower but it works work with all future versions of
php).


> Did anyone compile it for windows?

->
php-java-bridge.sf.net/snaps/php-java-bridge_3.0.6.zip

BTW: Please use php 5.1.2 instead of 5.1.1.

Jost Boekemeier

Hello,
  I'm developping a web using php.I'm using php5 and apache to develop my  web.  I want to use java for some tasks, so I'm very happy to know  that there is a support for intergrating php and java. I try to install  it after your instruction but I fail.  Please give me some advices.
  Thanks

Hi Curtis,

> I don't want to use an app server as this is just a
utility 
> application.

well, at least on unix the bridge runs more than 2-3
times faster when it is deployed into a application
server or servlet engine.

The reason is that the bridge uses the servlet for
activation only and then switches to a pipe
communication channel which is 1.5 times faster than
fastest unix domain socket implementation and more
than two times faster than local tcp sockets backed by
shared memory. 

> java.class.path = c:\php5\ext\php_java.jar 
> java.java_library =
C:\jdk1.4.2\jre\bin\server\jvm.dll
> java.java_library.path = C:\php5\ext

These settings might confuse the bridge, please remove
them.

> like this: javaw -Djava.library.path=c:\php5\ext

Can you please type:

  java -jar JavaBridge.jar INET_LOCAL:9267 5
Bridge.log

(please avoid backslashes, they have a different
meaning in java)
and check if your php_java.dll is indeed the
php_java.dll from the PHP/Java Bridge and not its
predecessor, the ext/java extension

After that php-cgi.exe test.php >result.html should
display that the backend is running.

> All that happens is winzip opens up with the jar
file.

This shouldn't happen if you have just installed a jdk
which associates .jar with java. -- It's not java's
fault that some public domain programs destroy the
created java file associations. :)

In any case, the following should always work:

c:
cd \php5
.\php-cgi.exe -n -q -dextension_dir=ext test.php
>result.html

The result.html should display "java running" and the
java command  used to start the backend. You can cut
and paste the complete command to a command shell,
please do not convert slashes into backslashes.

If this doesn't work for some reason, please open a
bug report, please use:
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233.
We'll then look at this issue asap.

Hi,

in version 3.x the java_session() only works when it
is the first java statement within your script. This
is a technical problem, when the tomcat response is
written, it is no longer possible to call
request.getSession(). Version 2.0.8 contained code
which allocated a new servlet instance in this case.

I have created a problem report for this, please see
PR1405042 for details
(http://sourceforge.net/tracker/index.php?func=detail&aid=1405042&group_id=117793&atid=679233)

This problem will be fixed in version 3.0.6.

However it is better to aquire a session handle as
early as possible. For example the following code is
problematic:

echo "test";
$session = java_session();
=> "Error response header already sent"

$s = new java("java.lang.String", ...);
$session = java_session();
=> null; "Tomcat response headers already sent"

Jost Boekemeier

I'm having issues getting the bridge to start with php 5.0.4 without running the bridge from the command line like this:

I don't want to use an app server as this is just a utility application.

Here are my settings and versions

java status 	not running 
java server 	localhost 



Any suggestions?  I don't know what to do about the java status as "not running".  The following instructions from the install.windows file make no sense on a windows machine with winzip loaded: Double-click on c:\php5\JavaBridge.jar. Or deploy JavaBridge.war (from the J2EE download) into your servlet engine or java application server and re-start it.

All that happens is winzip opens up with the jar file.  I don't know what point the author is trying to get across, but it ain't gonna happen on winders!

It says that if the above succeeded...  
But what if it doesn't?  

Thanks, I'm a little frustrated trying to get this running because I want to integrate the saxon xslt engine so i can get xslt 2.0 functionality (anybody making an extension?) and get on with my REAL development.  I'll go ahead and start developing as it stands now, but I'd like to see the bridge run when apache starts.

Your time is much appreciated.

Hi,

> java.servlet=User

java.servlet=On

should work.


> java_session() always returns NULL

the C/S protocol has changed from version 1.x to 2.0
[1]. Have you upgraded the backend to 3.0.5, too?

Can you please set the java.log_level to 5, open a
ticket (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
and attach the PHP/Java Bridge log (should be in the
J2EE Server's log file) at the end of this ticket?

Thank you very much for this bug report!


Regards,
Jost Boekemeier

[1] The [O]bject response now carries information
about the object's class and a cache value, both are
null at the moment. I think the code could be
rewritten so that 2.0.8 can work with a 3.x backend
and vice versa.

Hello,
 
I'm having troubles with 3.0.5 bridged with J2EE (Tomcat Application
Server). First of all, if I set
 
java.servlet=User
 
in my php.ini file, then I'm facing the same problem as before, regarding
the protocol violation error (403 forbidden).
 
If I change it to java.servlet="/JavaBridge/foo.php", then it works, but I
have another rather annoying problem :
 
java_session() always returns NULL, with or without parameters.
 
My code hasn't changed, only the bridge version (switched from 2.x to
3.0.5).
 
Any idea ?
 
Thanks,
 
Cedric
 

Apparently, bridge 3.0.5 has a dll that only works for php 5.0.x for 
windows.

I have php5.1.x installed. I don't know how to compile the dll and was 
wandering if it was available somewhere. Did anyone compile it for windows?

Hi,

AFAIK it is possible to run the bridge on a virtual server with memory 
limitations (i.e. < 40 MB per process) by including the -Xmx swtich in the 
java.ini and running the JVM as a separate process.

Is it also possible to compile the bridge with memory limits? Where do I set 
the -Xmx switch for
compilation?

Thank you!

Hi,

the following procedure can be used to install the
PHP/Java Bridge binary on a x86 debian based
distribution (debian, ubuntu, ...):

# Install java, for example /opt/IBMJava2-141

# Install the PHP/Java Bridge on debian
dpkg -i /media/cdrom/pool/main/r/rpm/*
rpm2cpio php-java-bridge-3.0.5-1.RHEL.i386.rpm | cpio
-iduv
cp -vr usr/share/doc/* /usr/share/doc
cp -vr usr/lib/php4 /usr/lib/php4/20020429/

# test
php /usr/share/doc/php-java-bridge-3.0.5/test.php4

The above procedure has been tested on Debian "Sarge",
but it should work on any x86 based Linux
distribution.


> tried to change "automake" to automake-1.6 in the
configure.gnu

Unfortunately it is not possible to compile the
PHP/Java Bridge on  Debian stable, this operating
system is much too old, sorry.


However, the generic install procedure (i.e. compiling
everything, from apache, autotools, php to php/java
bridge) does work on Debian, too.
Please either follow the INSTALL instructions or
please install the precompiled binary as described
above.


Regards,
Jost Boekemeier

Hi PHP / Java bridgers

When I try to configure version 3.0.4 I got the output below, with the
error at the bottom.

I have installed automake 1.6.3 as /usr/bin/automake-1.6 and I have
tried to change "automake" to automake-1.6 in the configure.gnu file,
but it didn't change anything.

Any clues?

Hi,

> I get [o(String):"555-555-6573"]

this is described in the NEWS and here:
http://cvs.sourceforge.net/viewcvs.py/*checkout*/php-java-bridge/php-java-bridge/documentation/API/html/java_8c.html#a60

The motivation was to make the following possible:
$s=new java("java.lang.String", '${12}');
$s=$s->substring(2);
$s=$s->substring(0, $s->length()-1);

echo "This is $s";
=> This is 12

echo $s+1;
=> 13

This "lazy evaluation" makes it possible to make the
java communication _much_ faster. In bridge version 2
we had to wait for a full round-trip for each
statement. 
Since version 3 we can simply create a zval proxy and
delay the java evaluation until PHP5/PHP6 calls
__toString() or __cast().

You may argue that echo $s should behave exactly as
echo "$s" and that the [object:"..."] notation should
be used by var_dump() only. But currently (in the
current PHP5/PHP6 code base) var_dump($s) and echo $s
both call __toString() to display objects.
So if we want to change the behaviour, we must change
this in PHP, I think.


> Session serialID 2f0 expired

That's a bug in the bridge 3.x codebase, see
PR1397154. 
I have just fixed it and committed it into the CVS
head. 


Can you please try the current snapshot
(http://php-java-bridge.sf.net/snaps)?


Regards,
Jost Boekemeier

I am having difficulity understanding this behavior. I looked in the docs 
with no success.

In bridge2.8, I make this call $javaObj->getAddr() and I get 555-555-6573

In bridge3.0.4 I get [o(String):"555-555-6573"]  for the same call.

It seems like I have to type cast it to a string. Can someone enlighten me 
why this is? Or am I missing something?


I am also getting this error once in a while for the same screen. It comes 
and goes randomly:

Fatal error: Uncaught [o(Exception):"java.lang.Exception: Invoke failed: 
[o(JavaBridge)]->deserialize((String)o(String), (int)o(Integer)). Cause: 
java.lang.IllegalArgumentException: Session serialID 2f0 expired."] thrown
