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

I just came up with two new questions. I'm sorry, I don't mean to be
annoying, but here is the only place where I can get the help I need.


1)
When I run the install.sh script it overwrites my php.ini with the PHP/Java
Bridge configuration.
It does not bother me right now because I'm not using any special
configuration, but when I go on production I will need my php.ini file. The
problem is that if I append the lines of the php.ini file that the
install.sh created to my original php.ini, the extension just doesn't load.
Is there any consideration that I should take into account before merging
both ini files?


2)
In a previous email, Jost told me that PHP/Java Bridge does not care about
CLASSPATH variable, and here comes my problem. I have to implement an API
which uses some XML files for its configuration. The xml is loaded using th=
e
getSystemResource method of the ClassLoader, which looks for a certain file
on the classpath as I understand. So, how should I indicate where those
files are using PHP/Java Bridge?
Right now I just added the path to the conf/ folder to the CLASSPATH and
everything worked.

Thanks

What I meant is that I got the error Java throws when it cannot find the
class that you're trying to instanciate.
It is the error I had pasted on my first e-mail:
CreateInstance failed: new Test. Cause: java.lang.ClassNotFoundException:
Test Responsible VM: 3.4.3@http://gcc.gnu.org/java/

Great! That was it! Now it is working!
Just another question... I had to restart Apache so that it would load the
new jar file... why is that? cache?

I will keep on trying with other things (now I have to get my *real* java
programs to work) and will keep you posted of any other problem I might get=
.

In my opinion, it's always useful to have a stable release of the source
code for those who don't use RPM or Debian packages.
I'm working with this at he company where I work, and I have to work with
RedHat so I could use the RPM binaries if it wasn't for the dependecies
problems I got (as I said, I installed Apache and PHP *manually* from its
source). Nevertheless I would probably want to install PHP/Java Bridge on m=
y
web server at home where I'm running Slackware and I would definitely need
to use the source package there.

This was mostly curiosity,  as I said I haven't work much with Java nor
JSP... but if it's the way to go, so be it.

Thank you very much again for your support. I hope that I can get this to
work and use it in many other places. I would be glad to help you enrich th=
e
documentation with my experience installing it, and I'm at your service for
anything else that I could be useful.

Hi,

I don't think so. Can you please open a problem
report, 
please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233

set the log level to 4 and attach the server log
there.

Ah, now we're are at something. So your problem isn't
that the class could not be found. The problem is that
the wrapper Java class you've written throws
exceptions or even errors. -- Most likely a
NoClassDefFoundError.

This will not work, because your class is not public.


> All methods are public.

Irrelevant.

I don't know what Andr'e and Jon think about this, but
I think we should discontinue the source distribution.
I think it causes too much trouble.

We could keep the (source-) RPM and debian packages.
Everyone else should use the generic binary or pull
the source code from the CVS.

You need to start a Java process as a service on the
computer. Which other program can start Java as a
system service? And what's the problem with tomcat?

Hi Jost,

Let me thank you again for all the help you've been giving me.

First of all I will answer the questions from your previous mail.

java_require("file://usr/local/apache2/htdocs/tests_java/Test.jar");
java_require("http://localhost/tests_java/Test.jar");
java_require("http://172.16.0.75/tests_java/Test.jar");
java_require("Test.jar");
And none of them seemed to work.

All of the above examples should work. Which error
message do you get?

The error I was getting was that it couldn't find the class. I checked the
JVM that it was using and it was wrong, as you suggested. So I changed it
and now it's working with the JRE I just installed. But now I've got a
different error:
CreateInstance failed: new Test. Cause: java.lang.IllegalAccessException:
Class php.java.bridge.JavaBridge can not access a member of class Test with
modifiers "public" Responsible VM: 1.5.0_11@http://java.sun.com/

This is my java code:

class Test
{
    public Test ()
    {
        System.out.println("Hi, I'm the constructor");
    }

    public String  saySth ()
    {
        return "Something stupid";
    }

    public static void main (String[] args)
    {
        System.out.println("This is the main");
        System.exit(0);
    }
}

All methods are public.

Regarding Security Enhanced Linux, I had seen the warning on your site so I
checked it before but it is not enabled in this box. Besides, I installed
the PHP/Java Bridge from its source because the RPM package didn't work for
me as the Apache and PHP were also compiled and installed *manually*, so th=
e
RPM would say that I needed some dependecies such as httpd...
Anyway, I think that now that you've shown me this error I had on my
configuration I'm closer to making it work.

As for the PHP Implementation does that imply that I should run
Apache/Tomcat? Because I was required not to use Tomcat in this case.
However, as I said in another mail, I don't have much experience with Java
nor Tomcat, so I'm not sure what are the advantages or disavantages does
that have.

Thanks again for your help.

Regards,

Andr=E9s

Hi,

The README is in the PHP/Java Bridge binary download
(php-java-bridge_x.y.z_j2ee.zip.


> java -jar JavaBridge.jar SERVLET_LOCAL:9676
> My Test.php is thus: (I tried using new Java(...)

Perfect.

Right.


> This can't be right!!!

Why not? This is standard PHP behaviour. -- If you
want object=>string autoconversion, this is available
and default in PHP6, but not in PHP5.

What exactly do you want to do? Do you want to convert
the created Object into a String? See the
documentation for java_cast($obj, PHP_TYPE) and
java_values($obj).

I guess what you want to do is something like:

$props = $system->getProperties();
// echo $props; // a java Properties object
$phpArray = java_values($props);


Please see our documentation at php-java-bridge.sf.net
for details.

I can't find a readme that mentions anything about this.  My 
configuration is as follows:

W2k
Php v5.16 or Php v5.21 ( can use either )
PHPEdit v4.6.3 in debug/server mode
JRE 1.5.10

Using the following I have successfully? performed the bridge

In a DOS box I run:
java -jar JavaBridge.jar SERVLET_LOCAL:9676

In my php.ini I have no java extension or module information

My Test.php is thus: (I tried using new Java(...) with no difference in 
results)

<?php

require_once("http://localhost:9676/JavaBridge/java/Java.inc");

$system = new JavaClass('java.lang.System');
$jversion = $system->getProperty('java.version');
//    echo 'Java version=' . $jversion . '<br/>';
echo 'Java version=';
echo $jversion;
echo '<br/>';

?>

Result is:

******************************
Java version=[o(String):"1.5.0_10"]
******************************

If I uncomment the line below assignment of $jversion result is:

******************************
Java version=Object id #19
Java version=[o(String):"1.5.0_10"]
******************************

This can't be right!!!

Thanks,

Jose
