Hi there, I' just downloaded and installed php/java bridge on a RH4, Apache
2.0, PHP 5.1.4 environment and I'm trying to make it work.
I just tried with a short script and I'm getting troubles to make it work.
I'd appreciate any help.
This is my java file:
class Test
{
public Test ()
{
System.out.println("Hi, Im the constructor");
}
public String saySth ()
{
return "Something stupid";
}
public static void main (String[] args)
{
System.out.println("This is the main");
System.exit(0);
}
}
I compiled it with javac and made the Test.jar file.
I tried putting the jar file on:
- /usr/local/apache2/htdocs/tests_java/ =DF my document root
- /usr/shared/java/
I even added the first path to mi CLASSPATH environment variable using php'=
s
putenv function.
Nothing seems to work.
This is my PHP file:
<?
$CLASSPATH =3D getenv('CLASSPATH');
echo "LA ORIGINAL: <br>";
echo $CLASSPATH;
echo "AGREGO EL PATH <br>";
$CLASSPATH .=3D ":/usr/local/apache2/htdocs/tests_java/test.jar";
putenv("CLASSPATH=3D".$CLASSPATH);
$CLASSPATH =3D getenv('CLASSPATH');
echo "LA POSTA: <br>";
echo $CLASSPATH;
@java_reset();
echo "<p><strong>Ejemplos de por ahi con clases propias de JAVA:
</strong></p>";
// get instance of Java class java.lang.System in PHP
$system =3D new Java('java.lang.System');
// demonstrate property access
echo 'Java version=3D' . $system->getProperty('java.version') . '<br />';
echo 'Java vendor=3D' . $system->getProperty('java.vendor') . '<br />';
echo 'OS=3D' . $system->getProperty('os.name') . ' ' .
$system->getProperty('os.version') . ' on ' .
$system->getProperty('os.arch') . ' <br />';
// java.util.Date example
$formatter =3D new Java('java.text.SimpleDateFormat',
"EEEE, MMMM dd, yyyy 'at' h:mm:ss a zzzz");
echo java_values($formatter->format(new Java('java.util.Date')));
@java_reset();
echo "<p><strong>Gusto? Bueno, aca viene lo complicado... levantar MI
clase</strong><p>";
try {
java_require("http://172.16.0.75/tests_java/Test.jar");
}catch (JavaException $e) {
if ($ex =3D java_last_exception_get())
{
echo "<strong>JAVA EXCEPTION: NO PUDE LEVANTAR EL JAR
</strong><br />";
echo java_values($ex->getMessage())."<br />";
}
}
try {
$o =3D new Java("Test");
echo (string) $o->saySth();
} catch (JavaException $e) {
if($ex=3Djava_last_exception_get()) {
echo "<strong>JAVA EXCEPTION: </strong><br />";
echo java_values($ex->getMessage())."<br />";
}
}
@java_reset();
echo "<p><strong>A ver que pasa con IpuConfig</strong></p>";
try {
$o =3D new Java("com.intraway.framework.IpuConfig");
$o->showXML();
} catch (JavaException $e) {
if($ex =3D java_last_exception_get())
{
echo "<strong>JAVA EXCEPTION: </strong><br />";
echo java_values($ex->getMessage())."<br />";
}
}
@java_reset();
?>
When I open that on my browser I get this:

Hi, which problems do you have with the PHP/Java Bridge? > java.lang.ClassNotFoundException: > com.intraway.framework.IpuConfigResponsible Well, just locate the Java library which exports the above class and then require it and its dependencies using the java require syntax. > VM: 3.4.3@http://gcc.gnu.org/java/ Also check if you Java VM can interpret the Java library (GNU java is not fully compatible with Java 1.4). If not, switch to IBM or Sun Java. In any case, please do not use @java_reset(), the CLASSPATH. In which documentation have you found this? Also it should never ever be necessary to create a wrapper Java library. The PHP/Java Bridge protocol is efficient enough so that these wrappers are *entirely* obsolete.

Hi, first of all, thanks a lot for your help.
which problems do you have with the PHP/Java Bridge?
I think the most important problem I'm having is importing my libraries.
For example, with the easiest exacmple I tried to use (my class Test), I
don't understand how should I import the jar file that I made.
I tried using for example:
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. Which would be the most appropiate way?
>
>
> > VM: 3.4.3@http://gcc.gnu.org/java/
Where should I define the VM that php/java bridge will work with?
I actually installed the Java J2SE JDK from Sun on my box on /opt/jdk_ ...
and that path is the one I set on the java.ini file.
In any case, please do not use @java_reset(), the
> CLASSPATH. In which documentation have you found this?

Ok, I'll remove the java_reset() calls. I read about php/java bridge in man=
y
places and tried to 'mix' the examples I got.
I shouldn't touch the CLASSPATH, right?
I'm not sure about what you mean when you say wrappers.
Thanks for your support.

All of the above examples should work. Which error
message do you get?
Note that most modern Linux systems come with Security
Enhanced Linux enabled. This means that the folders
tests_java, DOCUMENT_ROOT/tests_java and htdocs must
be tagged appropriately. Furthermore the back end runs
in a sand box which can only access files and
directories which belong to httpd (or the "apache"
user on RedHat linux). Please see the readme the
documentation on php-java-bridge.sf.net for details.
> Which would be the most appropiate way?
Copy Test.jar into {php.java.bridge.base}/lib and use
java_require("Test.jar"); If you have installed from
RPM, this directory is tagged as lib_t and has the
correct permissions.
> > > VM: 3.4.3@http://gcc.gnu.org/java/

It depends on how you start Java. As a sub component
of Apache or IIS? In this case the bridge uses the
java.java option from the php.ini.
> I actually installed the Java J2SE JDK from Sun on

The phpinfo() or the test.php page should display the
settings. Probably your system uses another .ini file
than you expect.
> Ok, I'll remove the java_reset() calls.
Most back ends ignore the java_reset() calls anyway.
Only the standalone container honors it. I thought
java_reset() generates enough noise so that people
don't use it in their scripts. Unfortunately it is
possible to suppress the warnings with the @operator.
> I shouldn't touch the CLASSPATH, right?
You can set it to any value you want. Java and the
PHP/Java Bridge don't care.
> I'm not sure about what you mean when you say
> wrappers.
I think hiding the libraries behind a facade is a bad
idea; people shouldn't write unnatural code. If you
have deployed your libraries into a J2EE back end, use
the libraries directly:
<?php
require_once("http://hostname:8080/JavaBridge/java/Java.inc");
java_require("foo.jar;bar.jar;...");
.. call your libraries ..
?>
If it turns out that some procedures should be
optimized, encapsulate the PHP code with the
java_begin_document()/java_end_document() pair. This
sends and executes the PHP code on the server side.
This is nearly as fast as Java code.

Jost Boekemeier

Hi Andrés,
I just saw that you use a recent version of PHP
anyway.
So please use the pure PHP implementation instead of
the C based implementation started as a sub component
of Apache.
Type:
/opt/jdkXXX/bin/java -jar JavaBridge.jar
SERVLET:8080
And then use your java from your scripts as follows:
<?php
require_once("http://localhost:8080/JavaBridge/java/Java.inc");
java_require("all.jar;my.jar;library.jar;files.jar");
...
?>
If this works and you really want to run Java as a sub
component of Apache, you can think about where to
store your libraries and how to set the security
policy in a second step.
Regards,
Jost Boekemeier

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.

Andr=E9s

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.

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= . > Besides, I installed > > the PHP/Java Bridge from its source because the RPM > > package didn't work for > > me > > 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.

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. > Apache/Tomcat?

And what's the problem with tomcat? 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. Regards, Andr=E9s Gattinoni |

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 Andr=E9s Gattinoni |
