php-java-bridge-users Mailing List for PHP/Java Bridge (Page 3)

I tried to compile the debian package on ubuntu hardy and it worked
fine, but when I install it wants tomcat5 which is no longer available. 
tomcat5.5 comes with hardy.  Is it possible to change the debian package
to use tomcat5.5?

 HI All,
I am trying to integrate php with java. As per that i have changed the
php.ini as
[Java]
java.java = "D:\Program Files\Java\jdk1.5.0_06\bin\javaw.exe"
java.java_home = "D:\Program Files\Java\jdk1.5.0_06\bin"
java.hosts = "127.0.0.1:8080"
java.servlet = On;

Mine is windows XP.

When i run the phpinfo() it shows like this:
  JAVA

Directive               LocalValue          MasterValue

java.class.path                               no
value                                      no value

java.home                                      no
value                                      no value

java.library
jvm.dll                                          jvm.dll

java.library.path                            no
vlaue                                       no value

an when i tried create an object of java class in any php page and when i
tried to execute it displays a page can not be displayed page. Can you
please tell me what is wrong and please suggest me the way to do the
integration.

Thanks,
Sridevi.

You've got it backwards. 
Please see the JSR 223 API spec and the Swing example. You can start Java with:

 jrunscript -p php-interactive 

and invoke php/gtk from Java.


> In my opinion, php is a powerfull language 

Sorry, but this is nonsense.

PHP is a language suited for the web. A PHP script cannot run for more than 30 seconds. If it does, one may receive out of memory problems because some objects cannot be reclaimed.

Furthermore the PHP/Java Bridge protocol assumes that a PHP script does not allocate more than 2^32 handles. Even the fastest computer cannot exceed this limit within 30 seconds. Bear in mind that the HTTP server and the web browser have similar limits.


> didn't know that python and scheme have their own GUI

They use Java's Swing or other toolkits.

Jost Boekemeier

Hello,

I do not understand very well what you mean by "PHP's reference counter 
can't reclaim cycles". Anyway, the bridge is started at the beginnig of 
the application as a subprocess and should be stopped at the end.
In my opinion, php is a powerfull language especially to manipulate 
string. It uses simple methods. Php syntax is very simple too.
For the GUI under Win32, java API isn't as easy to use as Gtk, and I 
didn't know that python and scheme have their own GUI (without using GTK 
libraries).

Thanks for your help...
Benjamin.

If you do, you'll quickly run out of memory because PHP's reference counter can't reclaim cycles. Second, the PHP/Java Bridge shouldn't be started/terminated for each request. And third, GTK isn't quite stable on Windows, anyway.

Hi,

you can terminate any Java process with System.exit(code).

Sorry, but this sounds insane. PHP is not a gerneral purpose programming language, you can't start a GUI loop from it. If you do, you'll quickly run out of memory because PHP's reference counter can't reclaim cycles. Second, the PHP/Java Bridge shouldn't be started/terminated for each request. And third, GTK isn't quite stable on Windows, anyway.

Why don't you use a proper programming language such as Java, Scheme or Python to write your GUI?

Hi,

> error Call to undefined function java()

the Java.inc provides this symbol (both the function and the constructor).

hi, I installed php java bridge on an ubuntu 8.04 server but it isn't
working as it is supposed to


on the phpinfo page it looks ok:


java
java support 
Enabled 
java bridge 
5.2.2 
java.java_home 
/usr/lib/jvm/java-6-sun/ 
java.java 
java 
java.log_file 
<stderr> 
java.log_level 
no value (use back-end's default
level) 
java.security_policy 
Off 
java command 
JAVA_HOME=/usr/lib/jvm/java-6-sun/
LD_LIBRARY_PATH=/usr/lib/php5/20060613+lfs: java -Djava.library.path=/usr/lib/php5/20060613+lfs -Djava.class.path=/usr/lib/php5/20060613+lfs/JavaBridge.jar -Djava.awt.headless=true -Dphp.java.bridge.base=/usr/lib/php5/20060613+lfs php.java.bridge.Standalone LOCAL:@java-bridge-25e6 2 
java server 
@java-bridge-25e6 
java status 
running 


http://servername:8080/JavaBridge/ works, but when I click settings i
get

error Call to undefined function java()


what is wrong?
I installed a debian package for php-java-bridge_5.2.2-1_i386.deb

I use php-gtk with javabridge under Win32... All my code is a standalone 
php script. To start JavaBridge, i use this command :
<?
// Starting JavaBridge
$port = 8080;
system("start JavaBridge\JavaBridge.jar SERVLET_LOCAL:$port");
$java_inc_filename = "http://127.0.0.1:$port/JavaBridge/java/Java.inc";
require_once($java_inc_filename);
?>

This works fine... At the end of my php script I would like to terminate 
the 'javaw' process (win32). I use the following piece of code :

<?
java("java.lang.System")->exit(0);
?>

This terminate the bridge but with a little delay and cause an error. Is 
there a better way to do that ?

Thanks in advance,
Benjamin.
