[Php-java-bridge-users] Installation of PEAR classes for java classes help needed!

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

Hi all,

First off, my knowledge of Java is very limited (thus the need for  
the PHP/Java bridge).

I have compiled and successfully installed the bridge for PHP 5.1.6  
for Mac OS X and wanted to install the PEAR class that represents a  
sample java class I have called HelloData (which simply prints "Hello  
the date is: mm/dd/yyyy").  I used the following command as per the  
instructions:

[PROMPT] sudo java -jar /usr/local/php5/lib/php/extensions/no-debug- 
non-zts-20050922/JavaBridge.jar --convert /usr/local/php5/lib/php  
HelloDate.jar

This ran for about 4 minutes before completing.  I was astonished  
that it would take so long.  After it completed I looked in the PEAR  
directory (/urs/local/php5/lib/php) and found several new directories:

drwxr-xr-x      5 root  wheel     170 Sep 10 14:19 HelloDate
drwxr-xr-x    416 root  wheel   14144 Sep 10 14:19 charsets
drwxr-xr-x   9200 root  wheel  312800 Sep 10 14:19 classes
drwxr-xr-x     46 root  wheel    1564 Sep 10 14:19 jce
drwxr-xr-x     82 root  wheel    2788 Sep 10 14:19 jsse
drwxr-xr-x    119 root  wheel    4046 Sep 10 14:19 laf
drwxr-xr-x    106 root  wheel    3604 Sep 10 14:19 ui

The first extra item makes sense, since it is the Java class I asked  
to be created in that command.  But the rest are a mystery to me  
(isse?  laf?  ui?).  And the "classes" directory is HUGE.  It looks  
like it has thousands of items (are these classes too)?

My questions are:
1) What are all those other directories for when I only asked for my  
sample class to be made into a PEAR class?

Thanks for the assistance.

Hi,

> found in library
> aclocal: configure.in

most likely autoconf is not correctly installed on
your operating system or some development files are
missing or maybe the debian people have finally
patched it to death... :)  AM gcj must be defined
either to the gcj program or to /bin/false. The
scripts use gcj to compile java to native code or they
don't do anything, if gcj is not installed. The
autoconf scripts work correctly on other OS, so we
will not add a workaround for this problem.

Please use the original autoconf, automake and libtool
programs, not the programs that came with your
operating system. The exact procedure is described in
the INSTALL document. 

However, on Ubuntu you don't need to compile the
bridge. You can either install the RPM with alien or
open it with a file manager and drag and drop the
content of the lib directory to your your php
installation and restart apache.

Jost Boekemeier

Re: [Php-java-bridge-users] Problem with start of javabridge onlinux

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

Hi Jost,
Thank you very much for replying. Actually XAMPP is not an app server
but its installer which install php,mysql and apache web server.
My php path is /opt/lampp/lib/php
And extension dir is /opt/lampp/lib/php/extensions/where is kept
javabridge.jar=20

Thanks again for kind reply.

Hi,


> grep: /opt/lampp/include/php/main/php.h: No such file or directory

if you can't compile the C code yourself, the binary download contains a
php-cgi and java.so which you can copy into your application server (I
assume XAMPP is an application server).

Another possibility is to use the pure PHP implementation
(http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bri
dge/java/README?revision=3D1.2&view=3Dmarkup)
or to simply use fopen/fwrite/fread to talk to your Java server:

[Php-java-bridge-users] Problem with start of javabridge on linux

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

Hi,
I have installed php with xampp version 1.5.1 on linux provided by
apachefriends.
Location of that installation is /opt/lampp/.
I wanted to install php javabridge with this so I used
php-java-bridge-3.0.8-1.src.rpm
I extracted it into /usr/src/redhat/SOURCES/php-java-bridge-3.0.8 as it
asked to do so.
My phpize is in /opt/lampp/bin. So I gave command=20
# phpize && //usr/src/redhat/SOURCES/php-java-bridge-3.0.8/configure
--with-java=3D/home/cherry/j2sdk1.4.2_04 && make=20

Copying command
[root@localhost bin]# phpize &&
/usr/src/redhat/SOURCES/php-java-bridge-3.0.8/configure
--with-java=3D/home/trkastar/j2sdk1.4.2_04 && make

Response is=20
grep: /opt/lampp/include/php/main/php.h: No such file or directory
grep: /opt/lampp/include/php/Zend/zend_modules.h: No such file or
directory
grep: /opt/lampp/include/php/Zend/zend_extensions.h: No such file or
directory
Configuring for:
PHP Api Version:
Zend Module Api No:
Zend Extension Api No:
-bash: /usr/src/redhat/SOURCES/php-java-bridge-3.0.8/configure: No such
file or directory

How can I achieve java support in this case.

Re: [Php-java-bridge-users] Java Bridge Error

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

Hi Brent,

in version 3.1.4 the autoconf script doesn't check if
the Java VM can really use JNI and always compiles the
java.so against unix domain sockets.

You can test this with the following command:

/usr/java/jdk1.5.0_08/bin/java -jar
/usr/local/lib/php/extensions/no-debug-non-zts-20050922/JavaBridge.jar
LOCAL:@dummy 3 ""

If the above command displays an error message, please
configure the bridge to use TCP sockets (or use the
J2EE/Tomcat back end) instead:

Please either set:

java.hosts = 127.0.0.1:9267
java.servlet = Off

and start Java manually with the command:

java -jar JavaBridge.jar 


Or start Java via a J2EE server or the Tomcat servlet
engine, copy JavaBridge.war to the J2EE autodeploy
folder, e.g.: /opt/tomcat/webapps, wait 10 seconds
while the Java server starts the bridge and set the
following options:

java.hosts = 127.0.0.1:8080
java.servlet = On

After that please restart the http server, for example
with: apachectl restart.

The test.php should now run without errors.


However, can you please open a ticket (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
and attach the output of the following command:

strace -s 1024 /usr/java/jdk1.5.0_08/bin/java -jar
/usr/local/lib/php/extensions/no-debug-non-zts-20050922/JavaBridge.jar
LOCAL:@dummy 1 "" 2>error.log

The error log should display the reason why Java could
not be started automatically. This will help us to
improve the latest version, which already contains
code for channel negotiation during startup.


Regards,
Jost Boekemeier

[Php-java-bridge-users] Java Bridge Error

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

To Whom It May Concern:

We are not able to get the Java Bridge to run properly, we are getting the 
following errors:

Error: The PHP/Java Bridge back-end is not running. Please start it and/or 
check if the directory 
/usr/local/lib/php/extensions/no-debug-non-zts-20050922 contains "java.so" 
and "JavaBridge.jar". Check if the following values are correct: 
java.java_home = java.java = If you want to start the back-end 
automatically, disable: java.socketname = java.hosts = java.servlet = If 
that still doesn't work, please check the "java command" above and report 
this problem to: php...@li....

No crahes after one hour of requests (w/ 1-minute delays). Seems pretty
rock solid to me :)

I'll go that route for now. Thanks!

Real Programmers don't comment their code.  If it was hard to write, it 
should be hard to understand and even harder to modify.

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

Hi Jonathan,

do you run javaw as a sub process of apache?

If so, can you please change the php.ini entry

java.java=javaw

to 

java.java=java

and then open the services dialog and allow the apache
service to open a console window. The procedure is
described here:

http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_18120

When you restart the apache service, a console window
appears. When the CPU usage jumps to 50% please type
Ctrl+Break simultaneously. It will create the thread
dump in a file called {server-name}-out.log or
{server-name}-err.log file, depending on the version
of JDK/JRE you are using.

The thread dump will show the thread name which causes
the trouble. My guess is that the thread is some Java
manager thread which tries to respond to some
unexpected events. -- Apache sometime has the habit to
send out a signal to all of its children. 

If that's the case starting Java outside of the Apache
domain should solve the problem.

Anyway, when you have the thread dump please open a
ticket (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
and attach the dump to this ticket.

Thank you very much for reporting this problem!

Yes, as a matter of fact I load jar files on demand; this is the
relevant part of the code (removed for brevity on previous post):

,----

| 
| $jars = array(
|               "$cwd/SpringDemo/",

[Php-java-bridge-users] Constant 50%+ CPU usage?

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

I've noticed some strange performance issues on my development machine
while using the JavaBridge... specs:

Windows XP Professional
Apache 2.0.55
PHP 5.1.2
PHP-Java Bridge 3.0.7a
Java JDK 1.5.0_01

When I start Apache up fresh, the javaw process that's spawned stays at
~0% CPU usage, spiking momentarily whenever my PHP code does something
with Java.  After some time passes, with zero activity on the server,
javaw's CPU usage holds steady at a consistent 50%+.  I haven't the
foggiest idea where to begin looking for answers, so any help is
appreciated.  (I'm happy to provide additional detail if needed!)

Best,
Jonathan

Re: [Php-java-bridge-users] RMI proxy stops working after several requests

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

Hi,

do you use the dynamic loader to load the classes?

We've had two tickets with similar problems (class
cast exception because the proxies were assignment
incompatible to each other). Both of them were closed
because the users provided no feedback. -- One user
reported that the suggested workaround (to move the
libraries to the global classpath) worked, after that
he was unable to reproduce the original problem.

However, I am quite sure there's still a bug in our
dynamic loader when dynamic proxies are used. 


Can you please run the server with:

-Dphp.java.bridge.default_log_file=/tmp/javabridge.log
-Dphp.java.bridge.default_log_level=6

open a ticket (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
and attach the full log at the end of the ticket?

The log file will be large, but it should contain
information why our dynamic loader has dropped the
proxy even though spring still keeps a reference to
it.


Thank you very much for the bug report!

[Php-java-bridge-users] RMI proxy stops working after several requests

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

Hello all,

First of all, thanks a lot for this amazing piece of work to everyone
involved. PHP on the frontend and Java in the backend is making a lot of
sense (a lot more than PHP-or-Java all the way 'round) over here :)

Now, my problem is the following: I have setup a Spring-based RMI
service, which works as expected the first times you try it from
PHP. After several times hitting the `refresh' button on the browser,
the proxy of the remote service "falls back" to the proxy factory
object.

My PHP code (without jar files and debug methods boilerplate):

,----
| $multService = null;
| try {
|     $classpathResource = new Java("org.springframework.core.io.ClassPathResource",
|                                   "beans.xml");
|     $beanFactory = new Java("org.springframework.beans.factory.xml.XmlBeanFactory",
|                             $classpathResource);
| 
|     $multService = $beanFactory->getBean("multService");
| 
|     $xval = (int) rand(0,100);
|     $yval = (int) rand(0,100);
| 
|     $x = new Java("java.lang.Integer", $xval);
|     $y = new Java("java.lang.Integer", $yval);
| 
|     $ret = $multService->operate($x, $y);
| 
|     if ($ret == $xval * $yval)
|         print "OK<br/>";
|     else
|         print "ERR<br/>";
| 
|     my_java_debug($multService);
| }
| catch(JavaException $ex) 
| {
|     my_java_print_stacktrace($ex);
|     my_java_debug($multService);
| }
`----

When everything is ok, the output is:

(Note that the dumped classes are not the same in both outputs)

Some things I observed:

* When it's still good, proxy instances are numbered $Proxy0, $Proxy1,
  ... etc., but the number doesn't change if there is a small time lapse
  between requests (a few seconds). I guess that's a normal behaviour,
  anyway.

* Given that the InvocationHandler object starts being replaced by a
  RmiProxyFactoryBean object, I tried to consecutively call
  $multService->getBean("multService") until I got the object I was
  waiting for (just in case some weird bug in Spring could be returning
  "this" from inside the Factory). It worked for a few tries, and then I
  got a null object and couldn't go forward.

* I tried with various RMI-recovering options for Spring's remote
  factory (cacheStub, refreshStubOnConnectFailure and
  lookupStubOnStartup), but to no avail.

* A restart of the web server solves (if we can call that a "solution")
  the problem.

* I couldn't find a pattern that would predict when RMI would fail. I
  thought that perhaps a run of System.gc() could trigger it, but a line
  like this didn't:

          $sys = new Java("java.lang.System"); $sys->gc();

These are the gory details:

* Web server is Apache 2.0 w/PHP 5.1.4 from Debian Sarge backports. 
* JVM is 1.5.0_06 from Sun.
* PHP-Java Bridge is 3.1.7 (for FC4).

Thanks in advance for any insights.

well, the PHP/Java Bridge is only the XML protocol, as
such it should run with any PHP version >= 4.3.2. I.e
with any PHP version which has a working version of
fsockopen.

We publish PECL and PEAR extensions for convenience,
but these extensions aren't necessary to call out to
Java libraries. 

The following example demonstrates how easy it is to
call out to Java libraries with nothing but fsockopen,
fread and fwrite:

<?
class Protocol {
  var $c;
  function __construct() { 
    $this->c=fsockopen("127.0.0.1",9267); 
    fwrite($this->c, chr(0100)); // mode 0 0, see
PROTOCOL.TXT
  }

  function createBegin($s) { 
    fwrite($this->c,sprintf("<C v=\"%s\" p=\"I\">",
$s)); 
  }

  function createEnd() { fwrite($this->c, "</C>"); }

  function invokeBegin($o, $m) { 
    fwrite($this->c, sprintf("<I v=\"%d\" m=\"%s\"
p=\"I\">", $o, $m)); 
  }

  function invokeEnd() { fwrite($this->c, "</I>"); }

  function writeString($s) {
      fwrite($this->c, sprintf("<S v=\"%s\"/>", $s));
  }

  function writeInt($s) {
    $p="O"; if($s<0) { $p="A"; $s*=-1; }
    fwrite($this->c, sprintf("<L v=\"%d\" p=\"%s\"/>",
$s, $p));
  }

  function writeObject($s) {
    fwrite($this->c, sprintf("<O v=\"%d\"/>",
$s->java));
  }

  function writeVal($s) {
    if(is_string($s)) {
      $this->writeString($s);
    } else if(is_int($s)) {
      $this->writeInt($s);
    } else {
      $this->writeObject($s);
    }
  }

  function getResult() {
    $res = fread($this->c, 8192); 
    $ar = sscanf($res, "%s v=\"%s");
    return substr($ar[1], 0, strpos($ar[1], "\""));
  }
}

function getProtocol() {
  static $protocol; if(!isset($protocol))
$protocol=new Protocol();
  return $protocol;
}

class J/*ava*/ {
  var $java;
  function __construct() {
    if(!func_num_args()) return;
    $protocol=getProtocol();
    $ar = func_get_args();
    $protocol->createBegin(array_shift($ar));
    foreach($ar as $arg) { $protocol->writeVal($arg);
}
    $protocol->createEnd();
    $ar = sscanf($protocol->getResult(), "%d");
    $this->java=$ar[0];
  }
  function __call($method, $args) {
    $protocol=getProtocol();
    $protocol->invokeBegin($this->java, $method);
    foreach($args as $arg) {
$protocol->writeVal($arg); }
    $protocol->invokeEnd();
    $proxy = new J();
    $ar = sscanf($protocol->getResult(), "%d");
    $proxy->java=$ar[0];
    return $proxy;
  }
  function toString() {
    $protocol=getProtocol();
    $protocol->invokeBegin("", "castToString");
    $protocol->writeVal($this);
    $protocol->invokeEnd();
    return $protocol->getResult();
  }
}
// Test
$i1 = new J("java.math.BigInteger",  "1", 2);
$i2 = new J("java.math.BigInteger",  "11", 2);
$i3 = $i1->add($i2);
echo $i3->toString() . "\n";
?>

To run the above example start the JavaBridge.jar, for
example by double-clicking on it or with:

java -jar JavaBridge.jar INET:0 4 JavaBridge.log

[Php-java-bridge-users] picking a suitable versions on windows

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

Hi,

I'm installing the php-java bridge on a windows2003 server with apache. 
I got it running on a dev machine already, and after some initial 
compatibility problems down to my version of php/apache it seems to be 
working fine. I have a few simple lines in php.ini and JDK 1.4 and I'm 
up and running with a java process starting at the same time as apache.

extension=php_java.dll
...
java.log_level=3
java.classpath="c:/php/ext/JavaBridge.jar;c:/htdocs/mysite/myjar.jar"

I got it running on php 5.0.4 and apache 2.0.55

I'd like to use the "latest and greatest" PHP/Apache if at all possible. 
So my question is - how do I decide what are the latest and greatest 
versions of php/apache that will work?

thanks,
andyh

Re: [Php-java-bridge-users] [Object types] Java Exceptions : how-to ?

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

Hi Jost,

Well thanks a lot for your explanation, and sorry for my
misunderstanding of the documentation (in fact if $ex->getCause() was
returning the error message, it was because it automatically invoked
the toString() java method of the Exception object - I just didn't
realize I had to test the $ex->getCause()'s type and not the type of
$ex itself).

Many thanks!

Etienne

Hi Etienne,

> invoked function's returned exception's type is

$ex->getCause() returns the wrapped exception: 

function getMyException() {
  static $MyException = new JavaClass("MyException");
  return $MyException;
}

try {
...
} catch (JavaException $ex) {
 
if(java_instanceof($ex->getCause(),getMyException()))
   {
     ...
   }
}


I'll fix the documentation.

[Php-java-bridge-users] [Object types] Java Exceptions : how-to ?

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

Hello guys,

I have an EJB container, which is JBoss, and I access the EJB's via
this wonderful PHP / Java Bridge OS Project.

In my Java code I use exceptions all the time to detect errors, but
most importantly error types, and hence I have customized exceptions
(as everyone has) to detect what error happened. They also contain
text messages but I do not want to rely on this, since they can change
anytime.

Well the problem is that in ususal Java code I would check for errors this way :
----------------------------------------------------
try {
     loginUser(login, password);
}
catch (BadLoginException ble) { // ... }
catch (BadPasswordException bpe) { // ... }
----------------------------------------------------
And so I would determine what failed and choose what to do on this basis.

Apparently the only possible thing via the bridge is to use the
JavaException type :
----------------------------------------------------
try {
     $myremoteBean->loginUser($login, $password);
}
catch (JavaException $je) { // ... }
----------------------------------------------------

So how can I determine which error appeared, without checking the
error message (which is - I think - a bad practice) ?
I tried with the "java_instanceof" function but it seems that the
returned exception is just a "JavaException" object, and that the
invoked function's returned exception's type is lost.

Thanks for your help!!

Re: [Php-java-bridge-users] Caching of (Java) objects (Lucene)

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

Hi Jost

After some tests I went for a java cache implementation with ehcache.
In this way I did not have to write Java, but more importantly it is
easier to to cache dynamically generated java objects (like query
filters which are different for each user) -- even persistent if I use
the disk cache when the JVM stops.

Now I need to upgrade the bridge to 3.1.7 and install it in a J2EE
server (still running the bridge with a stand-alone JVM)

Best regards

Will the requirements on PHP versions change? I mean, will PHP4 still
be supported with a pure PHP implementation in 4.0?

Hi Michael,

this problem sounds similar to the autoconf problem
that was reported earlier. -- In the next version
(4.0) the java.so and php_java.dll will be removed and
we'll use a pure PHP implementation instead. This
means that you don't have to compile and install a
non-standard PHP extension anymore to call out to Java
or .NET classes.

As a workaround please recompile the java.so with
CFLAGS="-DCFG_JAVA_SOCKET_INET".

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

and attach the result of the command:

strace -s 1024 -ff php test.php 2>error.log

at the end of the ticket?  Please also attach the
config.log there.

Technically yes. But I usually recommend to install
the JavaBridge.war into a servlet engine or J2EE
server.
The 3.1.6 download already contains a simple servlet
engine implementation which can be started with:

java -classpath JavaBridge.jar
php.java.bridge.JavaBridgeRunner

It currently can't handle session requests. But when
it's ready, we'll use a real servlet engine or the
JavaBridgeRunner as a fall back and the standalone
socket listener will vanish.

[Php-java-bridge-users] PHP JAVABridge installation problem

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

Hi,

I installed PHP JAVABridge3.1.6 in a Redhat Enterprise Linux 4 with 
Apache Http Server 2.2, PHP 5.1.4 and J2SDK1.4.2. When I start test.php 
from the command line, it shows:
Please permanently activate the extension. Loading java extension 
java.so now ...
java.lang.RuntimeException: java.lang.Exception: could not create 
socket: Local:@java-bridge-2c9.
...
Error: The PHP/Java Bridge back-end is not running.

But I have started the backend JavaBridge.jar and the output is:
JavaBridge version: 3.1.6.1
JavaBridge logFile:
JavaBridge default logLevel: 3
JavaBridge socket: INET:9267
JavaBridge thread pool size: 20.

It seems the client can't connect to the JavaBridge socket or connect to 
a wrong socket. Anyone can give me some idea. I am new to this. So any 
help would be greatly appreciated. BTW, does J2SDK works with PHP 
JavaBridge? I see the manual mention J2EE.

Thanks a lot.

Michael Zhou
