php-java-bridge-users Mailing List for PHP/Java Bridge (Page 101)

I'm a PHP programmer tasked with calling Java code written by someone else.  I successfully installed the Bridge on my Windows machine.  I wrote PHP script that calls Java code using the DYNAMIC LOAD method.  It works but the web page that contains the PHP script loads very slowly (15-20 seconds) the first time, but a bit faster the succeeding times (5 seconds).

What the Java code does is supposedly simple, it reads a short string value from a relational database, and passes it to PHP script to display.  Oh, but the Java code requires a lot of libraries like log4j, dom4j, asm, xom, etc. (more than 20 of them).

My immediate question is: Is there a way to improve performance, especially the first time the webpage (PHP script) is loaded?

My deeper question is:

  What happens exactly with "dynamic loading"?  Is the sequence of events below accurate?

  1) User requests for a web page that contains a PHP script that calls Java code.
  2) The system loads all Java base classes (libraries).
  3) The system loads the Java Virtual Machine (JVM). 
  4) The system loads all Java libraries needed by the PHP script.
  5) The system executes the Java code.

  What happens exactly with "static loading"?  Is this sequence of events accurate?

  0) User starts up the welcome page of a web application. 
      The system loads all Java base classes (libraries) AND 
       the Java Virtual Machine (JVM).
  1) User requests for a webpage that contains a PHP script that calls Java code.
  2) The system loads all Java libraries needed by the PHP script.
  3) The system executes the Java code.

Filip

Hi,

PHP should display a clear error message. If it doesn't there's either a bug in the
bridge or in PHP. Which PHP/Java Bridge version do you use? I old C implementation or
the pure PHP implementation?

Michael was right. Using ArrayList it worked.

I'm tailing the apache error log and nothing appeared there with that
script. With the rest of the work I've been doing with php/java bridge I ca=
n
see all the output there.

I will try later to set the log level to 4 and will post the response here.

there should be some output. Can you please set the log level to 4 and check the log of the back
end?
Please see our FAQ for details how to enable the log of the PHP/Java Bridge back end.

My guess is that this is a PHP issue. Since PHP version 5 PHP does no longer report any errors to
the client. They are logged in the HTTP log or in the configured PHP log file or in the System
log.

do you want to call a servlet from another web application or a different container?

The former is possible by using the RequestDispatcher, please see

If I'm not mistaken, List is an interface, not a concrete class.  Hence, =
you
cannot say new List().  It seems like Vector() and ArrayList() are =
fairly
standard implementations of List, so you could try

$oList =3D new java('java.util.ArrayList');

Hi

[please excuse the delay]


your code is a little bit unusual because it uses a generated proxy class. Looking at the 
current implementation it seems that the bridge caches the generated proxies, which it shouldn't
do. But this is a minor problem.

> public class ObjPassing
> {
> 	public void visit( Object o)
> 	{ System.out.println("first visit method"); }

> }
>

The bridge should invoke the second method, because the closure (the dynamic proxy) implements the
IVisit interface, which makes it cheaper than the first method which should have a weight of at
least 32 (IVisit -> Object conversion)


> is it possible to call the second method? if yes, where is my fault?

Can you please set the log level to 5 or above? The bridge should display the weight and why it
has selected the wrong method. My guess is that you have loaded IVisit from a different
classloader, so that it is assignment-incompatible with IVisit used by the visit method. Do you
have two java_require() calls in your code?

Jost Boekemeier

do you want to call PHP beans from the JSF framework or do you want to call managed JSF beans
from PHP?  We've had the former, but the code has been dropped in favor of a more general solution
which uses the JSR223 API. (Our implementation was similar to Spring's
"DelegatingVariableResolver" described here:
http://www.springframework.org/docs/reference/webintegration.html).

On the other hand accessing managed beans should be easy: 
 
 ctx = FacesContext.getCurrentInstance();
 ctx.getApplication().getVariableResolver().resolveVariable(ctx, name)

> 1. Create an account in phpbb when user creates an account in application 
> through jsp and vice-versa.

Do you want to create the account from JSP or JSF?  In any case, what does it mean to "create an
account"?

Jost Boekemeier

Hi guys, I'm having problems with a List object.

I have the following code:

<?php
$mAnnouncements =3D array (
 'Welcome.wav',
 'CPAA.wav',
);
print("Array:  <br />");
print_r($mAnnouncements);

print("<br />Creating List Object...<br />");
$oList =3D new java('java.util.List');
foreach ($mAnnouncements as $ann)
{
    $oList->add($ann);
}
print("List: <br />");
print_r($oList);
print("<br />");
for ($i =3D 0; $i < $oList->size(); $i++)
{
    print("Value:" . $oList->get($i) . "<br />");
}
?>

When I run it I get this output:

Array:
Array ( [0] =3D> Welcome.wav [1] =3D> CPAA.wav )
Creating List Object...

And it just dies there. No error on the output nor on the logs.

I'm using php/java bridge on that box withoud any problems, working with my
own java classes, but when I need to create this List object I get this
problem.
Any ideas? Do I need to require any file with java_require?

Thanks in advance

Hello,
this is my first post in this thread. I install the bridge 
(php-java-bridge_3.2.1a_j2ee) on Tomcat 4.1 / Java 1.5.0 / Apache 2.2 / 
PHP 5.2.3
The install was a little bit difficult, but now its works fine. Thank 
for the mailing-list and project homepage.

My Question.
I have a php-based cms system (typo3) and a webapplication (pure java) 
it is running under tomcat. Both works and in the typo system i can 
instatiate java objects. Fine! Every request goes first to the  
index.php in the cms. I need a mechanism to call an servlet in the other 
pure java-webapp. (i would like to track referer/parameters e.g. in this 
app)

I know the mechanism to intantiate java objects via 
java_require('any.jar'), but how call a servlet in a other tomcat 
container?
(perhaps a beginer question)

regards joersch

hi to all.

first of all, i'm sorry for my bad english.. i hope you will understand me.

I was doing an experiment with php classes and java interfaces.

i have a java class:

public class ObjPassing
{
	public void visit( Object o)
	{ System.out.println("first visit method"); }
	
	public void visit( IVisit o)   //  <-- i wish to run this one
	{ System.out.println("second visit method"); }
}

I need to pass a php object(Obj is it's name) who implements my IVisit
java interface, to ObjPassing, but i never manage to invoke the second
method: the first method is always invoked.

from php i do:
$obj = new Java('ObjPassing');
$obj->visit(java_get_closure(new Obj(),null, new JavaClass("IVisit")));

is it possible to call the second method? if yes, where is my fault?

thank you

Hi,

Just wondering, if there is some test case/example to integrate jsp/jsf 
application with phpbb through php-java bridge.
Though, I know jsp/jsf but zero in php, so if some body could give me some 
suggestions/hints/pointers for such case then that will be great.
I intend to install phpbb using fantastico and looking for simple 
integration in existing jsp/jsf application (running in tomcat 5.5 (jvm - 
java 5) under linux OS), something on these lines:

1. Create an account in phpbb when user creates an account in application 
through jsp and vice-versa.
2. Logs in one then logs-in in another and vice-versa.
3. Logs out in one then logs out in another and vice-versa.
4. When user updates profile in one (at least password) then password gets 
updated I another and vice-versa.

I guess this should be possible through php-java bridge but wondering if 
anybody already has done something similar and give me some 
pointers/suggestions.

Any help will be highly appreciated.

Thanks.

Hi Thomas,

first of all thank you very much for the feedback.

Since version 4.1.8 the pure PHP implementation also supports INET and INET_LOCAL, see the NEWS
file.

The difference between SERVLET/SERVLET_LOCAL and INET/INET_LOCAL is that the former reads
meta-information like X_JAVABRIDGE_OVERRIDE_HOSTS and X_JAVABRIDGE_OVERRIDE_REDIRECT. This
information is used to select the fastest available channel, which is INET/INET_LOCAL on windows
and named pipes on Unix.

In theory the INET/INET_LOCAL channel should be faster, because the SERVLET* "meta" channel
requires one additional round-trip. But on modern operating systems this shouldn't be a problem.


> Why has the version to be > 5.1.2 ? Only too old, any bugs ?

Well, the functionality needed by the bridge is there, but all PHP 5 versions < 5.1.2 
have serious problems. Just remove the check from Java.inc, run the "bench" test on 5.0.4 and 
you'll see what I mean. :)


> Is it possible to adapt the pure PHP implementation for PHP4 ?

try/catch etc. is not available in PHP4. The binary download contains a php_java.dll for PHP4,
which could be used as follows:

 // check if the PHP4 extension is loaded. Otherwise load Java.inc
 if(!extension_loaded("java")) require_once("java/Java.inc");


[compiling ]
> 3) Binaries for PHP 5.2.x

Yes, this is possible. PHP 5.2 and all future versions of PHP are supported. IBM has a
tutorial which describes how to compile PHP 5 and PHP 6 on windows. Instructions how to
compile the bridge against PHP 5 or 6 on windows can be found at the end of the INSTALL document.

However, you don't need to compile the C code. It is neither faster nor does it add
additional features[1] except for JVM launching.


Regards,
Jost Boekemeier

[1] This may change in the future, although I'd prefer to add Proxy and ProxyException 
interfaces directly to the PHP core.

Hello,

I'm developing Simple Groupware and JavaBridge 4.1.8 is used to call
the jCIFS Java library from PHP (bringing CIFS and NTLM to the PHP
world). Tests are done on WinXP SP2, Sun Java 1.6.0_02.

My questions:

1) pure PHP implementation:
does it only support SERVLET_LOCAL / SERVLET ?
(start java -jar JavaBridge.jar SERVLET_LOCAL:8080 3)

Where is the difference between SERVLET and INET ? Is anyone of them
faster ?

I tried INET / INET_LOCAL and got:
(start java -jar JavaBridge.jar INET_LOCAL:8080 3)
Notice: Undefined index: content_length in
H:\sgs\src\lib\java\Java.inc on line 1259

Warning: fread() [function.fread]: Length parameter must be greater
than 0 in H:\sgs\src\lib\java\Java.inc on line 1259
protocol error: , Invalid document end at col


2) pure PHP implementation for PHP 5.0 and 4.x:

Why has the version to be > 5.1.2 ? Only too old, any bugs ?
Is it possible to adapt the pure PHP implementation for PHP4 ?


3) Binaries for PHP 5.2.x

I found the "legacy" package containing binaries for older php
versions, is it possible to build a new one for the latest php
versions ?
At least for win32, this would be a real time-saver for a lot of people.

Thanks,
bye
Thomas

I have an application that stores configuration in a file called
config.properties.  It resides in a jar file underneath all of the package
dirs, with the rest of the class files.  The class that loads the config
options cannot find this resource when run through php-java-bridge.

 

All access is done through a central singleton called Toolbox.  I wrote some
code to circumvent the Toolbox code and try to load the resource manually,
via PHP and a separate Java application.  Here's what I get:

 

PHP

java_require("myjar.jar");

$Toolbox = new JavaClass("my.package.Toolbox");

$toolbox = $Toolbox->getInstance();

$class = $toolbox->getClass();

$r = $class->getResource("config.properties"); // null

$r = $class->getResource("/my/package/config.properties"); // null

$r = $class->getResource("my/package/config.properties"); // works, but see
below

 

Java

(myjar.jar in the classpath)

Toolbox toolbox = Toolbox.getInstance();

URL r;

r = toolbox.getClass().getResource("config.properties"); // works

r = toolbox.getClass().getResource("/my/package/config.properties"); //
works

r = toolbox.getClass().getResource("my/package/config.properties"); // null

 

myjar.jar contains

META-INF/MANIFEST.MF

my/package/config.properties

my/package/Toolbox.class

my/package/<. other .class files .>

 

Based on my understanding, the Java code is exhibiting the correct behavior
in terms of which resource names work and which don't.  I don't think the
my/package/config.properties should work, but if it did work for both, I
could use it.  Unfortunately, this is a library which will be used both by
PHP scripts and a Java app.

 

Any idea what I'm missing here?

 

Michael.

Hi Daran,

> > /home/dpatrick/php/downloaded/php-java-bridge-4.1.8/java.c:118: error: too few arguments to

the C version 4.1.8 currently doesn't work in a threaded environment (I forgot to add a TSRMLS).

Please use the pure PHP version instead. Or please use the latest stable version, which is version
3.2.1.


I will reorganize the download area accordingly.

Sounds like one (or more) of your arguments are evaluating to null or generating an error when evalutated.  In this case, the argument would likely be skipped.  Check your undeclared 'tsrm_ls' term.  This might be the cause of the error.

Hope this helps.

Hi,

> It just says:
> Cause: java.lang.ClassNotFoundException: Unresolved external reference:
> java.lang.NoClassDefFoundError.

then you're out of luck. Java doesn't have a proper module system, the above error means that you 
have compiled against a different API and than what is available now.

When you get the above exception without any indication which class or package is missing, you 
can't proceed. The only way to solve the above Java error is to step back and read the 
documentation of the Java package, which should list the external package dependencies and their
versions.

I'd prefer to remove the C code entirely.

The PHP code is currently between 2 to 50 times slower than the old C code. 
But this will change with 4.2.0, which adds a client-side cache to Java.inc. 
With this cache the PHP code suddenly becomes 1.2 to 2 times faster than the C code.

Hi Jost,

Thank you for your anwser.I tried your suggestion and it didn't gave me that
error but i still don't get it to work.
It just says:
Cause: java.lang.ClassNotFoundException: Unresolved external reference:
java.lang.NoClassDefFoundError.


This is what i did:

moved libAspriseOCR.so to /usr/lib/jvm/java-1_4_2-sun-1.4.2.13
/jre/lib/i386/client/libAspriseOCR.so
moved aspriseOCR.jar to /usr/lib/jvm/java-1_4_2-sun-1.4.2.13
/jre/lib/ext/aspriseOCR.jar

restarted tomcat and apache

See my code below, Java code is directly copied from the manufactures
website:

/*

The original java code:


import com.asprise.util.pdf.PDFReader;
import com.asprise.util.ocr.OCR;

PDFReader reader = new PDFReader(new File("my.pdf"));
reader.open(); // open the file.
int pages = reader.getNumberOfPages();

for(int i=0; i < pages; i++) {
   BufferedImage img = reader.getPageAsImage(i);

   // recognizes both characters and barcodes
   String text = new OCR().recognizeAll(image);
   System.out.println("Page " + i + ": " + text);
}

reader.close(); // finally, close the file.
*/


// My php5 Code

$aJarFiles[] = "./external/lucene-demos-2.0.0.jar";
$aJarFiles[] = "./external/lucene-core-2.0.0.jar";
$aJarFiles[] = "./external/junit.jar";
$aJarFiles[] = "./external/checkstyle-all-4.2.jar";
$aJarFiles[] = "./external/bcprov-jdk14-132.jar";
$aJarFiles[] = "./external/bcmail-jdk14-132.jar";
$aJarFiles[] = "./external/ant.jar";
$aJarFiles[] = "./external/FontBox-0.1.0-dev.jar";

$aJarFiles[] = "./AspriseJavaPDF.jar";
$aJarFiles[] = "./aspriseOCR.jar";

java_require(implode(";",$aJarFiles));

$file = new Java('java.io.File',"./changes.pdf");
$reader = new Java('com.asprise.util.pdf.PDFReader',$file);
$reader->open();
$pages = $reader->getNumberOfPages();


for($i=0; $i < $pages; $i++) {

   $img = $reader->getPageAsImage($i);
   $ocr = new Java('com.asprise.util.ocr.OCR');
   $text = $ocr->recognizeAll($img);

   print $text;
}


Any idea what's wrong with my setup? i Put everything in a zip if you would
like to take a look:

Hi,

> local unix socket

this was default until version 4.1.8. In version 4.1.8
we have temporarily switched it off, since 4.1.8 is
only a thin wrapper around the pure PHP PHP/Java
Bridge implementation "Java.inc".

Do you have the libnatcJavaBridge.so? This is the
library which implements unix domain socket
communication.  It depends on whether your Java 
supports JNI and whether or not your JVM can (and is
allowed to) load a native library.

If not, the bridge reverts to local TCP sockets or
named pipes. 

IMHO unix domain socket communication is obsolete on
modern operating systems. The only exception is
FreeBSD, due to a bug in FreeBSD's local TCP socket
implementation (Nagle's algorithm switched on per
default and PHP doesn't have a way to switch it off).

Jost Boekemeier
