php-java-bridge-users Mailing List for PHP/Java Bridge

Hi Kok,

thank you very much for the bug report. java_session() and
java_session(null, false) should behave differently.

I will fix this in PHP/Java Bridge version 6.2.1rc3.


Regards,
Jost Bökemeier

Hi Jost,

    My point is, is it possible to configure java_session(); such that
it returns a null when no session currently exists? Or is there any
function to determine whether a session already exists?

Thanks.

Regards,

    Kok Hoor

If JavaBridge.war back end is running in a servlet engine or JEE
server, the code:

<?php require_once("java/Java.inc");

java_session();

?>

uses an existing session or creates a new one, depending on whether
your browser(!) has sent a session cookie or not.

java_session() (or session_start(), for that matters) should be called
before any response has been created. Furthermore, if an HTTP front-
and a JEE back-end is used, java_session() must be the first Java
statement in your PHP script. Otherwise you'll get an error message
that a session cannot be allocated (you won't get a session, not even
a new one).

It sounds as if your browser has cookies switched off, so that the
server tries to allocate a new session for each request.

Hi,

    I am a newbie using php-java bridge. Is there any way to make any calls
to Java to return session only if it exists, and not create a new one?

    The reason I ask is because, by default, our existing Java web does not
create any session until after the user logs into our system.

    I have tried java_session(null,true) and java_session(null,false), but
regardless, a new session is created whether I like it or not. I even tried
calling $java_context()->getHttpServletResponse()->getSession(false), but an
exception is thrown.

    I am using JavaBridgeTemplate621rc2.war

Thanks.

Its only possible if the php process and the java process are running under
the same user on the same machine and the user who should see the frame is
also the user running the java + php process.

An example would be if you have some swing GUI and you want to code
some logic in PHP
and ship the app as a whole, so no _remote_ webserver is required.

You cannot show a JFrame to a _remote_ user, if thats what you want.

Hi Dominik,

Not necessarily web requests, no.

Both bridges can be used to control a Java desktop application (think
of a Java report designer or something) through PHP scripts.

The only difference is that Zend uses a binary protocol similar to
PHP/Java Bridge version 1 and supports dynamic class loading through
java_require(), while the PHP/Java Bridge uses an XML protocol and
requires you to add all libraries to the java application class path.

I think this says it all. You are using a different product from an
other vendor (ZEND).


Also you are mixing up things... you want to show a Swing Frame
through a Web-Request
which is not possible... the java code is executed on the server..
Where should the frame be rendered? On the administrators screen?

If you just want to render some views in the webbrowser, you better stick
to JavaSCRIPT and leave the javabridge alone.

Can we please stop this conversation?


Please re-read the install instructions *carefully* and follow them
*exactly*, simply copy/paste the code given there.

The instructions are correct; if java complains about
"Helloworld.jar", you have made a mistake, the install instructions
use "HelloWorld.jar".


Regards,
Jost Bökemeier

Hello!

Failed to load Main-Class manifest attribute from Helloworld.jar

Is it "Helloworld.jar" or "HelloWorld.jar"?

Either you wrote a bug and the Main-Class manifest attribute doesn't exist, or your JDK is incompatible with your JRE.

Hi,

For example by using some file manager.


Regards,
Jost Bökemeier

Hi,

the "MANIFEST.MF" file is a standard text file. You can create it with
a text editor (vi, emacs, edit, wordpad or similar).

Jost Bökemeier

Then you a probably not using the PHP/Java Bridge at all.

Please follow the instructions from
http://php-java-bridge.sourceforge.net/pjb/desktop-apps.php


> please what do you mean by Java log file?

The argument to -Dphp.java.bridge.default_log_file=

> The communication can be traced by starting your application with the options: java -Dphp.java.bridge.default_log_file= -Dphp.java.bridge.default_log_level=4 -jar HelloWorld.jar

What are the last 10 lines from your Java log file?

I am sorry, but I cannot reproduce this problem. Your code should
display "undefined function: java_require".


Please follow the instructions at:

Hi,

this problem appeared in version 6.2.1 test1 and has been fixed in cvs
head about a month ago.


Please use the official PHP/Java Bridge download:

   http://php-java-bridge.sourceforge.net/pjb/download.php

There is no stable version 6 yet. PHP/Java Bridge version 6 will be
released at the end of september.


Regards,
Jost Bökemeier

I'm getting the exception below.  Anyone seen this one before?  These are the scenarios that I have tried that all result in this:

-) Using the release version of the template jar without any modifications
-) Building my own war and packaging it up similar to the template war
-) Both the scenarios above under JBoss 5.1 and Tomcat 6 (Yes, I know JBoss uses tomcat but I wanted to rule out JBoss adding something odd to the mix)

For what it's worth, I'm using OSX and MAMP on the php side and on the java side I'm using java 1.6.0_20.

Not any more.  We are on a tight timeline and I was preemptively looking for solutions if I were to be told that persistent connections aren't being used.

Hi everyone,

i am working on a PHP application ,i need to introduce a .jar ,so my JavaBridge 
turn well with some examples,but when i tried the example in the site which 
concern the  message dialogue,that doesn't work.
So it doesn't display a message dialog,below are all the codes i used:

***************HelloWorld.java*****************
import javax.swing.JOptionPane;


public class HelloWorld {
  public static void main(String args[]) throws Exception {
    JOptionPane.showMessageDialog(null, "hello world");
    System.exit(0);
  }
  public void hello(String args[]) throws Exception {
    JOptionPane.showMessageDialog(null, "hello " + args[0]);
  }
}

so i created the HelloWorld.jar,and it's worked,so below is the PHP code:
*************************
<?php 
java_require('http://localhost:10088/HelloWorld.jar');

$world = new java("HelloWorld");
echo $world->hello(array("from PHP"));
?>

so when i launch this,nothing displayed.

Please really need someone for help.



      

Hi Daniel,

> Is there a clean way to use BASIC authentication for php to java http requests?

Doesn't make sense to me. Basic auth is handled by the browser/user,
not a server-side script.

Do you have a use-case?


> looking for something more than a global set of credentials.

You can declare access rules per rmi method, see EJB/JEE spec and
RMI/IIOP example.

the PHP/Java Bridge uses persistent connections, yes.

If a PHP process "j" is connected to a java thread "k", j will
continue to use k until j or k is destroyed (OOM condition or other
fatal error).


Note: persistent connections are not used if you program your own
servlet. That's up to you:

Is there a clean way to use BASIC authentication for php to java http requests?  I'd like to adjust this on a per web user basis so I'm looking for something more than a global set of credentials.

Thanks in advance,

Daniel

The java code I'm trying to call from php relies on thread locals for storing security and transaction information.  In the zend version of the bridge, I noticed that each call to a java operation could potentially result in a different thread handling the call.  My initial tests on the php/java bridge suggest that's not true about this implementation.  I'm writing to determine if my initial tests are coincidence or if I indeed can assume that the same server side thread is allocated for the duration of a single page rendering on the php side.

Thanks in advance,

Daniel

Thanks Jost

Jost,

I committed them.  I did not build any scripts, just updated what you already had.  I also added a lot of php files to show how to use it.  Look at the BIRTindex.php.  Can you check it to verify everything went up ok?
