Ant: [Php-java-bridge-users] problems with own classes

[Jost B. <jos...@ya...>]

Hi,

It could be that some google caches still link to the
forum.  I guess they will disappear over time.  --
Sorry for the inconvenience, but it was difficult to
manage both, the forum and the mailing list.

I think there were issues with old Sun JDK/JRE's on
linux during the transition to NPTL.  But since
1.4.02_02 this shouldn't be an issue anymore.

The servlet API is an optional package. The J2EE
download contains it, but not the standard SDK.  One
has to link to servlet.jar or j2ee.jar explicitly.

I don't know what your library does, but it could well
be that it requires a servlet environment.  In this
case please create a JavaBridge.war and deploy it into
e.g. tomcat.  

If it doesn't require a servlet, you can just download
the sun j2ee distribution and copy j2ee.jar to
/usr/share/java.  


> ProvisoFactory since it was written by someone else

Okay, but what does it do?  Does it require a servlet
environment (in which case you must create a
JavaBridge.war and deploy that) or does it reference
the servlet classes by accident, which may happen if
the vendor has compiled against the servlet classes
even though they are not needed for normal operation?

[Php-java-bridge-users] =?ISO-8859-1?Q?_problems_with_own_classes___?=

[Tamas S. <Tam...@gm...>]

first of all thx for your quick response... and sry for using the forums
even if they were closed allready (but i didnt see any signs for the forums
being closed).

well for setting up the bridge i used the ibm java environment
(IBMJava2-SDK-142.tgz) because the sun java kit didnt work so well (actually
i had a failure during compiling the bridge so i decided to give the ibm
java a try and it worked flawlessly). is it possible that the ibm java
doesnt contain this javax/servlet/ServletContext? is this delivered in the
standart sdk packages? also is it more likely available in the sun or ibm
java? or do i have to grab them seperated? 

to be honest i really dont know much about the creation of the
ProvisoFactory since it was written by someone else and they handed over to
me with the task to find a way to establish a stable and fast communication
from php to java. searching the web i found the php-java bridge and decided
to give it a try. well in the beginning evrything worked fine (as i told
before i could use all the testfiles which came with the bridge) but when it
comes to use these proviso classes (librarys) nothing works the way it
should.

so the basic workaround for my problem would be to make available the
library again. another question is: do i have to enable servlets on the
bridge or am just getting confused by the "javax/servlet/ServletContext"
thing? also when i search the files you mentioned and the package isnt
available what to do? set up the bridge with a new java (i could try sun's
java) or do i just download those missing packages/libraries and make them
available in the classpath?

thx in advance and i really apreciate the help you are offering

greetz tamas szabo

ps: also i wanted to say how great your work is! how did this project start?
did you simply miss php/java compatibility and decided to build your own
bridge?

Hi, 
 
[in the future please use the mailing list, this forum has been closed] 
 
> basically i understand that the class i was  
> reffering to wasnt found 
 
No, the exception says that the class was found.  
 
The exception is an internal exception which reflects a problem with the way
how java loads libraries: It appears when a procedure application failes,
either the constructor, initializers or the call of a procedure. 
 
The above is the call of the login procedure, which failed because the JIT
has found an open reference to a library or library version which was
available during creation of the ProvisoFactory but which has been removed
since then. 
 
The missing class can be found either in the optional j2ee.jar, servlet.jar
or other libraries. Please note that the version may be important, so please
check with the person who compiled ProvisoFactory. 
 
Another thing is possible. Java library vendors generally know this problem
and compile their java libraries so that the critical paths do not contain
references to libraries that customers might not have. But this is dangerous
because one cannot check all paths during the release tests. It may well be
that the vendor who shipped the library has made a mistake.

hi there, 
 
im kinda new to this whole stuff but i allready figured out how to set up
the bridge and how to load my own classes (but my knowledge is very limited
in php aswell as in java). my proble is that i need to set up a server which
should authenicate the clients for the whole intranet. basically the
authentication is done with custom java classes which should send back a
ticket (in form of a cookie) to the client. now after i set up the bridge i
wanted to do some tests... first off all i used the tests supplied with the
bridge and they all worked fine. then i tried to write some basic php and
java codes to test it out further (basically i did what was done in the in
the array example but i wrote it myself). all of these tests went fine. but
now im trying to do some basic stuff with the classes provided for the user
athentication and i get an error like this: 
 
java.lang.Exception: Invoke failed: [class
at.wave.proviso10.ProvisoFactory]->login. Cause:
java.lang.NoClassDefFoundError: javax/servlet/ServletContext 
 
basically i understand that the class i was reffering to wasnt found but
why? javax/servlet/ServletContext should come with the basic java sdk
shoudnt it? is this something i have to enable myself or do i have to
configure the bridge for it? 
 
the bridge is running on a redhat fedora core 3 with an apache (but
basically this info shouldnt be necesarry as the bridge is running well with
the tests supplied with the bridge).  
 
any help would be apreciated (sry for my bad english) 

Ant: [Php-java-bridge-users] PHP-JavaBridge Integration Problem

[Jost B. <jos...@ya...>]

Hi,

> but when i restarted my windows 2000 the Java 
> Failsed to start

How do you start the java backend?  Have you deployed
the JavaBridge.war into an application server or have
you copied the JavaBridge.jar into the autostart
folder?



> set java.socketname 

Well on Unix the bridge starts automatically if the
java.socketname and the java.hosts options are
switched off.  Unfortunately this is not possible on
windows because fork()/exec() are not available. Also
the php-java-bridge.service script only works on Unix
-- there are some GPL programs which allow java
programs to start as a system service, but we cannot
incorporate them into the distribution.

On windows I recommend to deploy the backend into
tomcat which has the ability to run as a windows
system service.

[Php-java-bridge-users] PHP/Java Bridge 2.0.7 available

[Jost B. <jos...@ya...>]

The version 2.0.7 of the PHP/Java Bridge is now
available.
    
 The binary for RedHat Enterprise Linux, RedHat Fedora
1, 2 and 3 (uses PHP4):
  

http://prdownloads.sourceforge.net/php-java-bridge/php-java-bridge-2.0.7-1.RHEL.i386.rpm?download

 
  The binary for RedHat Fedora 4 (uses PHP5):
  

http://prdownloads.sourceforge.net/php-java-bridge/php-java-bridge-2.0.7-1.FC4.i386.rpm?download
 
 Windows XP:
  

http://prdownloads.sourceforge.net/php-java-bridge/php-java-bridge_2.0.7.zip?download

  
 For the rest:
  

http://prdownloads.sourceforge.net/php-java-bridge/php-java-bridge_2.0.7.tar.bz2?download

 

New features:

* A dynamic class loader has been added which loads or
re-
loads classes, jars as needed.  
The /usr/share/java, /usr/share/java/ext and php
libdir/lib are 
scanned for system libraries.  java_set_library_path
and 
java_require can now load and re-load directories 
containing .class files.  


* A thread pool has been added.  The default size is
20 
threads, which can be changed with the 

  -Dphp.java.bridge.threads=<number>

flag.  If set to 0, the thread pool is switched off.

* java_get_values() has been added for PHP5.  This
primitive
evaluates an Array, Collection or Hash on the java
server and 
returns it as an array to the php interpreter.  This
avoids 
network round-trips (e.g. when iterating over members
of a
container), but consumes lots of memory in the php 
interpreter.

* An "invoke" cache has been added which makes the
bridge 
more than twice as fast as earlier versions.


The bugs from the following problem reports were
fixed:

1223240	PHP 5 RPM for FC4:                            

Binaries are are now available for RHEL (PHP4) and
Fedora 4
 (PHP5) and higher.  A source RPM is available to
re-compile 
the sources (for Suse Linux for example).

1217592	UTF-8 not working on Windows:	           
Fixed (see ChangeLog for details).

1217113	Add a "reset" primitive:                      
   
java_reset() has been added which resets all internal
state.

1212938	Officially support MONO/.NET:               
Available as a separate download.  To build a mono/net

backend use the --with-mono=<path-to-ikvmc.exe> flag.

1212919	Servlet engine/Tomcat support:              
Tomcat4 and Tomcat5 are now supported. To build with 
servlet support use the
--enable-servlet=<path-to-j2ee.jar> 
configure flag.

1212916	Revise windows documentation and
functionality:
Fixed, see README.WINDOWS for details.

1208576	new Java() fails with a "NoClassDefFound": 
Fixed.  The bridge now catches the error and calls new

JavaClass() instead.


There is a PHP/Mono Bridge (2.0.8pre) available
which allows one to create GUI (GTK, GNOME, ...) 
applications with PHP.  It is possible to call 
GTK/GNOME code from PHP and vice versa.  Unlike 
previous attempts, the bridge integrates well into the
target environment as it uses reflection once to 
determine what can or cannot be accessed:

Ant: [Php-java-bridge-users] how to stop javabridge

[Jost B. <jos...@ya...>]

Hi,
 
I think Kai Londenberg's new DynamicClassLoader detects if a .jar file must be re-loaded.  
 
In any case, the version 2.0.7 (which is currently available as 2.0.7pre3) has a java_reset() primitive which resets the backend. Please see the tests.php4/reset.php for details.
 
If you really want to stop the backend:
 
$sys = new Java("java.lang.System");
$sys->exit(0);
 
 
The above code doesn't work if you have deployed the JavaBridge.war into your application server.  In this it should be possible to re-start the servlet via some AS specific admin interface.

Jost Boekemeier

[<pa...@ya...>]

hi,
i am starting to integrate javabridge within my project, but i'm confused about one problem~everytime I want to modify my jar file,I have to restart my computer and javabridge to catch my new jar file~
 
is there another way to stop javabridge without restarting my computer??
I am sorry if the question is stupid .
but this problem has troubled me for a while.
thank you in advance~~~

No surprise there, they have their own ways of doing things ;-)

Agreed, its on internal network so if I'm feeling paranoid I can

that's great!  The C code will not be changed any further, so I expect that the future versions of the bridge will continue to run, even though we don't have the chance to test on MacOS X.
 
 
> I did not succeed at getting it running using the (named?) sockets
 
OSX should have "unix domain sockets" too, but I guess the problem is JNI related. Apple has changed JNI in an incompatible way; there was a discussion on the gnu java mailing list about this issue.  
 
If you compile with 
 
  make "CFLAG=-DCFG_JAVA_SOCKET_INET"
 
the bridge will use TCP sockets instead even if the configure script reports that "unix domain sockets" are available.  This flag is necessary on BSD, too, as BSD usually runs the linux JDK which cannot load the natcJavaBridge.so files that BSD creates.
 
One problem with TCP sockets is that most java implementations create a socket which binds itself to *all* available network interfaces.   This might become a security issue if the backend runs on the web-server.
 
We should change this, a LOCAL: backend should bind itself to the local interface only.

Hi Jost,

You just made my day :-)

I got back to look at php-java-bridge today and immediately was able  
to compile version 2.0.7pre2 against Apples Java 1.5.0_02-36 on Tiger  
10.4.1. I did not succeed at getting it running using the (named?)  
sockets, but it happily works using the hosts method which is perfect  
anyway. Then I 'wasted' ;-) the whole day plugging in our production  
system jars with amazing ease and it all just worked. A big thankyou !

Ant: [Php-java-bridge-users] Does Apache 2.0.54 supports PHP/JAVA Bridge?

[Jost B. <jos...@ya...>]

Hi,
 
I am not sure where this is from, but I can assure you that the information quoted below is wrong.  
 
As I understand it, it's exactly the other way 'round. The bridge should work better in a process environment than in a threaded environment.  For several reasons; for example every time a threaded http server aborts the execution of a module and the shutdown hook of the module is not called, the server may leak resources (socket handles, memory etc.).  Furthermore there is no process barrier, the php module in one thread may read the data of a php module running in another thread.
 
Even though a http server creating processes (e.g. Apache 1.3 or 2.0 with prefork MPM) responds slower than a threaded server (e.g. IIS or Apache 2.0 with thread pool MPM), I would recommend it for php modules.
 
Anyhow, the above discussion doesn't apply to the PHP/Java Bridge.  It doesn't matter whether you run the java.so in a process- or threaded environment. The native code in java.so simply forwards requests to a Java VM running in a different process, and, if SEL is enabled in the kernel, even in a different domain.

Jost Boekemeier

It definitely works with Apache.

And what you've read does apply to the *old* php java bridge, which
has been replaced by this one.=20

I'm currently using it with Apache 1.3x, mod_php and php5 under
Debian.=20

Apache 1.3 is forking subprocesses, while Apache 2.x at least *has*
Threaded (worker) implementations.

Suse is an RPM based Linux Distribution, so I would try to use the
rpm. If that doesn't work, you'll have to compile it yourself.

[Php-java-bridge-users] Patch: Adds dynamic class-loading/unloading and a Thread Pool

[Kai L. <K.L...@li...>]

Hello,

Like I wrote earlier in the help forum, I wrote a small patch for the
php-java-bridge to enable it to dynamically load and unload classes.

With this patch, it's possible to have fast develop and test cycles
with a real mix of Java and PHP. (Without sacrificing performance, due
to caching and lazy evaluation btw)

Oh, and it adds a simple Thread Pool implementation.

Hope you'll integrate this into the next version of the
php-java-bridge.

thank you very much for the bug report.  Version 2.0.7 probably fixes
this bug, the code doesn't require semaphores anymore. But feel free to
create a bug report anyway.


Can you please add the following lines to the beginning of the php-java-
bridge startup script:

# remove old semaphores 
ipcrm -s `ipcs -s | fgrep 0x00009168 | awk '{print $2}'`

and re-start the bridge?

If it still doesn't work, please add a new problem report and attach the
output of the command:

   strace `which php -i` 

to the ticket.

Jost Boekemeier

And it works fine as an apache sub-process :)
Enabling java.socketname, the script php-java-bridge fails:
Starting php-java-bridge: Error: PHP/Java Bridge module not installed.
                                                           [FAILED]

I've noticed that the script fails because I've no output from the php cli:
for example php -v gives me no output.
Disabling the option ; java.socketname=/var/run/.php-java-bridge_socket in
my java.ini, php -v and the other commands work!
Haow could I enable the php-java -bridge as a service?????
Any ideas??????

[Php-java-bridge-users] Tomcat JavaBridge.war

[Jost B. <jos...@ya...>]

Hi,
 
I have created a standard JavaBridge.war file which could be deployed tomcat 4.  I have tested on tomcat 4 only, but it should/will work on any modern servlet engine:
 
 
http://php-java-bridge.sf.net/JavaBridge.war
http://php-java-bridge.sf.net/java.so   (php4 module for RedHat Linux)
 
To install it please deploy the JavaBridge.war into your servlet engine and java.so into your Linux PHP 4 extension directory.  Edit the php.ini so that it contains the following entries:
 

extension = java.so
[java]
java.hosts="127.0.0.1:8080"
java.servlet=/JavaBridge/PhpJavaServlet

Known problems:
 
* Please do not deploy the current JavaBridge.war into a server connected to the internet. 
 
* It is currently not possible to call back php from java procedures (JSR223 will handle this).
 
* Communication through the servlet is slower than communication through local ("unix domain") sockets, but it is still much faster than SOAP based web services.
 
* the java.so above is for Linux (intel) only.
 
I will commit the source code as soon as possible. (I seems I have forgot the cvs account password during my vacation..)
 
 
Regards,
Jost Boekemeier

[Php-java-bridge-users] Tomcat5 Cluster

[Jost B. <jos...@ya...>]

Hi,
 
in the next version (2.0.7) it will be possible to deploy the backend ("JavaBridge.war") into a standard servlet engine or application server (e.g. tomcat, jrun or websphere).
 
Most of these servlet engines or application servers support "load balancing" and "fail over", and I think it isn't necessary to also keep the experimental (and broken) "multicast" code inside the PHP/Java Bridge.  
 
If nobody objects, I will remove the files multicast.c, multicast.h and Listener.java from the bridge.  
 
 
Regards,
Jost Boekemeier

Thank you very much for pointing out this problem in the windows
documentation.  The corrected documentation is attached:


* Install a J2RE >= 1.4.0, for example Sun JDK 1.5.0

* Download and extract php-java-bridge_*-win32-php5.zip into the
  folder: c:\php5.

* Activate the PHP/Java Bridge in the global php.ini file. 
  Add the following entry to your php.ini:

          extension = php_java.dll
          [java]

* Start the java VM. Double-Click on c:\php5\JavaBridge.jar

* Open a command window in c:\php5 and type:

   .\php-cgi test.php >result.html 

  Open the file result.html with a browser.  Search for the "java
  status" entry, it should be "java status: running", and examine the
  java properties at the bottom of the page. 

* Copy your java libraries (.jar files) into c:\php5\lib. Copy the
  php_java.dll into the extension directory of your PHP 5.0.3
  installation.



* Copy the test.php into your web-server document root and browse to:

    http://localhost/test.php


Thank you very much for the bug report.

Jost Boekemeier

[Php-java-bridge-users] Bug ? or mistake from me ?

[Michel S. <mic...@ti...>]

When running the test "fatal error" java not found in line 6.

I made the necessary changes in the test, but nothing has been settled =
down.

Thanks for your answer.

Re: [Php-java-bridge-users] Quick Question

Hi,

The c:\php5 folder is hard-coded in the php.exe (php-cgi.exe). However,
you can load the dll from any location within c:

extension = ..\windows\php_java.dll
[java]


I am not a windows expert, but I dont think it is possible to load the
dll from another drive, at least not without re-compiling the exe or
without changing it with a hex editor.

[Php-java-bridge-users] Quick Question

[Tim <TRh...@Th...>]

SourceForge Dudes,

    Just a quick question. I unfortunately have to run this on a windows
box and wanted to put it in a different location than C:\PHP5 but I was
unable to. I changed all the urls in test.php to point to the correct
place but it still errored out. What file do I need to tweek to get this
to work? Other than that I think the project is awesome. My companies
main product is Java based and this has made some of my work SOOOOO much
easier, very cool idea.

[Php-java-bridge-users] Update: PHP/Java Bridge 2.0.6 available

[Jost B. <jos...@ya...>]

 
-> http://php-java-bridge.sf.net/php-java-bridge_2.0.6-pre2.tar.bz2
 
The following problems were fixed since 2.0.6-pre:
 
* The bridge did some magic to work around a problem in the java reflection API which does not allow one to access members of a non-public instance obtained from another instance; an iterator for example.  The implementation was wrong and has been rewritten to use setAccessible(true). If this fails, due to security restrictions, the bridge searches all interfaces and super classes to find a matching method.  In the normal case (no security restrictions) the new implementation is much faster than the old one.
 
* The name "java_set_library_path" was misleading.  It is still there but the recommended method is now:  java_require(<FEATURE>);
 
* The bridge searches the sysurls only once, a resource which is not found is now blacklisted.  
 
* Since some operating systems could not handle ms timeouts correctly, the multicast response timeout is not 1s.
 
* Default session timeout: gc_maxlifetime is passed to the session created on a node.  
 
* If the socketname is off, the php-java-bridge script starts 4 redundant backends.
 
* The load balancer should work better than before.
 
* Documentation updates.
 
 
The official version 2.0.6 will be available next week.

Jost Boekemeier
