[Php-java-bridge-users] Demo of PHP/Java Bridge 3.0 + jsr223 API

[Jost B. <jos...@ya...>]

Hi,

a number of people have asked how to invoke php
scripts from a java servlet or from a java
application.

Instead of answering these questions individually I
have created a demo. The ~4MB linux tar file can be
downloaded at

-> php-java-bridge.sf.net/php-java-bridge-3.0-demo.tar

It contains:

 * JavaBridge.jar version 3.0
 * java.so version 3.0, intel/linux 386 binary
 * php version 5.0.5, intel/linux 386 binary
 * php-script.jar (new since version 3.0)

 * HelloWorld1.java: Allocates a script from the
   build-in CGI pool using a local FileReader, calls
   the local (CGI-) php continuation and invokes php 
   script methods.

 * HelloWorld2.java: Allocates the script from 
   an external HTTP pool using a URLReader, calls
   the remote php continuation and invokes php
methods.


For older java versions (<1.6) it also contains:

 * script-api.jar ((C) by Sanka Samaranayake,
distributed under the Apache license)


Extract the php-java-bridge-3.0-demo.tar in /tmp, for
example with the command:

  cd /tmp
  tar xvf php-java-bridge-3.0-demo.tar 

And run the sample, for example with:

  sh runHello.sh

To run the second demo, move the HelloWorld.php to
your web server, make sure that the PHP/Java Bridge is
installed on this web server and check that its
php.ini contains _only_ the following entry:

[java]
# enable the http tunnel
java.servlet=On

After activating the new .ini (re-start the
web-server), you can run the second example, which is
similar to the first one except that it uses a
URLReader to allocate and to call out to a php
instance running on a remote http server.

[Php-java-bridge-users] passing String[] argument to a constructor

[Guillaume D. <gui...@po...>]

Hello,

we're having problems passing a string array to a constructor. We construct
the array in PHP as follows :

$Array = new JavaClass("java.lang.reflect.Array");
$String = new JavaClass("java.lang.String");
$entries = $Array->newInstance($String, 2);
$entries[0] = 'hello';
$entries[1] = 'world';

and we call the constructor as follows :

try {
	$req = new javaClass('MyApp');
	$req->ProcessFunction($Array);
} catch(JavaException $ex) {
       print "$ex";
}

The error message we get is:

[o(Exception):"java.lang.Exception: Invoke failed:
[c:MyApp]->ProcessFunction2(([Ljava.lang.String;)c:java.lang.reflect.Array).
Cause: java.lang.IllegalArgumentException: argument type mismatch"]

The constructor expects a String[] parameter.

Any clues on how to create a Java String[] from PHP?

I can create Integer, Date, Vector or String objects but arrays ...

I tried:
$String = new JavaClass("java.lang.String[]"); // silly but hey, that's what
debugging is all about :)

Any help would be much appreciated.

Thanks in advance!!

[Php-java-bridge-users] Apache access to .php files

[Kevin K. <zi...@gm...>]

I'm attempting to set up the php-java-bridge in the "load balancing
and failover" approach.  What access does Apache need to have to the
.php files in my project?  Should I expect the following to work
unchanged?

*install warfile
*access http://myhost/JavaBridge/numberguess.php

Or do I need to grant apache access to that directory, and map
JavaBridge/**.php to the webcontent/JavaBridge directory?

[Jost B. <jos...@ya...>]

Hi Kevin,


> I've configured the mod_jk differently

I think we can ignore mod_jk for this discussion,
because it is not essential for the PHP/Java Bridge. 
-- Unless you forward everything to tomcat, which
would render Apache, PHP and PHP/Java Bridge useless.

It's an internal operation of the bridge. Essentially
you have two pools, the HTTP/PHP pool (usually at :80)
and the Tomcat (JavaThread) pool (usually at tcp port
:8080). For each php instance request with java code
in it, the bridge allocates an instance from each
pool. The instances communicate using a cps style
(they pass each other's continuation). 

To make this work, the two pools must be accessible to
the bridge, of course.  "Accessible" means that they
must listen on TCP ports. (The bridge also supports
unix domain sockets for the local backend, but this
requires that you inject a JNI library called
"natcJavaBridge.so" into the java VM).

No, of course not.

Privilege dropping means that one part of the server
runs with suid rights while other parts run with lower
privileges. POSIX requires that, when a thread changes
its uid, all other threads change their id, too. After
that tomcat cannot accept connections on the
privileged port 80 anymore.

If one wants to expose /etc/passwd and /etc/shadow to
everyone on the internet, yes...


> Apache is running on port 8080, though, and it leads

So the apache pool listens on 8080 (I thought that's
the tomcat pool).  On which TCP port does tomcat
listen?

Re: Ant: [Php-java-bridge-users] PhpJavaServlet using tunneling instead of CGI?

[Kevin K. <zi...@gm...>]

I've configured the mod_jk differently, Apache is the "first handler"
for all requests, passing requests in servlet mappings to Tomcat via
the AJP connector.  Tomcat no longer even runs an HTTP Connector.=20
This appears to be the preferred way to configure mod_jk with Apache2.

Regardless of that, I'm confused about the request method.  The
request is a Get request, as defined by the browser makeing the
request.  Where and why would it be translated to a Put?

I'm also confused about this:
"For a production system, however, it is assumed that all requests go
through the standard http port and that a native http server listens
on this port. -- The reason is that java cannot drop privileges, so it
is not possible to connect a java servlet engine to port 80."

First:  I don't want to run apache on port 80, surely this port isn't
hardcoded anywhere?
Second:  What do you mean that "java cannot drop privileges"?  It's
quite possible to configure Tomcat to answer requests on port 80,
although that's not what I want to do personally.

I can't just use the default port--there's nothing running there.=20
Apache is running on port 8080, though, and it leads me to the problem
I'm having.

What component "should" be changing Get requests from the browser into
Put requests for the server?
Why is the servlet using CGI for Get?  Get is just the method, and is
a valid request type for these requests according to the HTTP spec.

Ant: [Php-java-bridge-users] PhpJavaServlet using tunneling instead of CGI?

[Jost B. <jos...@ya...>]

Hi again,

> > Is there some configuration I need in my web.xml

> > service?  

I just noticed that you may want to include the php
script, i.e. call out to php from a standard java
class or servlet.

I think you know about the req.redirect(...), which
would redirect the request to the apache port.

However, I am currently working on full jsr223
integration: The implementation allocates a php
instance from the apache pool by opening a
URLconnection passing it the current java continuation
(a thread). The allocated php instance in turn
connects back to the java continuation passing it the
proxy allocated with java_closure().

The allocated script is stored in the
javax.script.ScriptEngine when the user calls
scriptEngine.eval(<phpScript>). He/she can call out to
the php script by using the methods from
javax.script.Invocable.

I likely have misunderstood your question and the
previous answer was sufficient. :) If not, a preview
of PHP/Java Bridge version 3.0 will be available next
week.

Jost Boekemeier

Yes. This feature will be available with PHP/Java
Bridge 3.0 which will be published in december.

The version 2.0.8 already supports everything
necessary to fully implement jsr 223 except that some
methods are currently private.  But if you make the
Context class and the getContext() method public, you
can already call php scripts from java:

* "include" the php instance from the apache pool and
pass it the current java continuation 

* the php instance closes over its environment (see
java_closure) and passes it to the passed java
continuation

* in your java continuation you can call into the
closure as often as you want.

* when the java continuation (e.g. the service method)
terminates all allocated php continuations terminate,
too.


Regarding the compilation on windows, Steven has
posted an excellent article on the list, please see

[Jost B. <jos...@ya...>]

Hi Kevin,

CGI is only used when the controller servlet
(PhpJavaServlet) receives a get or post request.

Usually apache listens on the http standard port :80
and php instances are allocated from the apache pool.
The php instances in turn connect to the :8080 backend
using put requests. mod_jk becomes obsolete if one
doesn't have .jsp files anymore.

Okay.

The doGet invokes the cgi machinery, yes.  It is there
to help during development, where it is difficult to
work with two servers.

For a production system, however, it is assumed that
all requests go through the standard http port and
that a native http server listens on this port. -- The
reason is that java cannot drop privileges, so it is
not possible to connect a java servlet engine to port
80.

Just use 

  http://localhost/JavaBridge/test.php

instead of

  http://localhost:8080/JavaBridge/test.php

help to detect errors in launching scripts configuration.

[Php-java-bridge-users] PhpJavaServlet using tunneling instead of CGI?

[Kevin K. <zi...@gm...>]

The servlet seems to be calling php on the commandline (CGI) instead
of through Apache.  That also seems to be failing, as requests return
the file but no php processing.

I'm running under Apache2 with both php and the mod_jk connector
installed.  My java applications function correctly, and I can see the
test.php file if I use Apache directly.  It indicates that Java is
enabled.

I've installed the JavaBridge war (opened it in Eclipse, actually),
and added my php-cgi.exe and associated .dll files to the WEB-INF/cgi
directory.  I updated the web.xml to indicate that the file is called
php-cgi.exe

My requests to .php files seem to be serviced by the PhpJavaServlet, I
can place debugging breakpoints there.  The requests, being GET
requests are serviced by the doGet method.  However, I notice that the
javadoc for this method believes that it will only be called in a CGI
context.  It then ultimately does the System.exec(..) CGI approach.

I have this information in my php.ini, though it isn't clear to me how
the PhpJavaServlet would know how to find it:

[java]
java.hosts=3D"127.0.0.1:8080"
java.servlet=3D"/JavaBridge/PhpJavaServlet"


Is there some configuration I need in my web.xml file to tell the
Servlet how to connect back through the Apache service?  I tried
removing the *.php filter, but that didn't seem to change anything --
still got the file back with no processing.

Ant: Re: Ant: [Php-java-bridge-users] Installation Problem

[Jost B. <jos...@ya...>]

Hi,

[apache craches when running the test.php from the
php/java bridge with the following settings:

> extension=php_java.dll
> [java]
> java.class.path =
C:\apachefriends\xampp\php\php_java.jar 
> java.home = C:\Programme\Java\jre1.5.0_02
> java.library =
C:\Programme\Java\jre1.5.0_02\bin\client\jvm.dll

I could reproduce this problem with XAMPP. But as I
said, this has nothing to do with the PHP/Java Bridge.

XAMPP contains the predecessor of the PHP/Java Bridge,
"ext/java", which has been removed from the official
PHP5 distribution a long time ago.

Please install the PHP/Java Bridge *instead*, which
means that you must take out the ext/java patch which
your distributor applied to your PHP5 binary. Please
use an official version of PHP 5 instead, for example
the download from php.net:
http://www.php.net/get/php-5.0.5.tar.bz2/from/a/mirror

[Jost B. <jos...@ya...>]

Hi,

Isn't it possible to deploy the backend (the
JavaBridge.war) into tomcat or some other j2ee
environment?

In this setup the httpd handles the php requests and
the bridge connects to tomcat (to the "j2ee backend")
as necessary, please see the sessionSharing.jsp and
sessionSharing.php examples in the j2ee download.

The "PHP environment", as you call it, isn't much
different than the environment you're familiar with.
The PHP/Java Bridge adds a "middle tier" so that php
scripts don't have to connect to databases directly
anymore. Whether you run the standalone backend (the
JavaBridge.jar) or the j2ee backend (JavaBridge.war)
doesn't matter: since 2.0.8 the j2ee backend is
(nearly) as fast as the standalone backend.

When java.servlet=On is set and a client sends a
request for a php page with java code in it, the php
java bridge internally connects to a controller
servlet (default: "/JavaBridge/PhpJavaServlet"), asks
for the page and then lets the http/php instance
render the content. The standalone backend works
simliar except that the standard j2ee services are not
available.

Binding actions to php/jsp scripts or servlets via a
standard web.xml file is just right, ihmo. I don't
have plans to add similar functionality to the
standalone backend.

Jost Boekemeier

[Php-java-bridge-users] where to place WEB-INF and mapping problem.

[AFeng <da...@21...>]

Hi,
recently i have to rewrite the login part of the project,
which was build in JSP/Java originally, into PHP/Java.

login.html
===========
<form method=post action="/gdca/SingleClient_Auth1">
<input type=text name=username>
<input type=submit>
</form>

note that "/gdca/SingleClient_Auth1" is _equal_ to "WEB-INF/classes/gdca/SingleClient_Auth1.class",
set in WEB-INF/web.xml with:

  <servlet>
    <servlet-name>SingleClient_Auth1</servlet-name>
    <servlet-class>gdca.SingleClient_Auth1</servlet-class>
  </servlet>

it will be fine while running in J2EE environment (such as Weblogic),
coz URLs were transformed and run as java classes at server-side automatically.

BUT when using PJB in PHP environment, i have no idea where i should put the WEB-INF folder,
and how httpd transformed/handle the URLs, and run the java classes, if web.xml works.

Anyone have ideas?


Thanks!

best regards
Zhang

Subject: Installation Problem
To: php-java-bridge <php...@li...>

I've installed PJB 2.0.8 and it used to work fine, but not now.
I supose I do something that breaks the installation, so I check every step=
,
but i can't find what's is brong.

The Problem:
When I run the test.php Apache crush, and I can't get anything in the log
(is in level 4)

I'm on a Windows XP, with Apache 2 and PHP 5 (installed with XAMPP)

This is what I have (only the lines that are relationated with this):

PHP.INI:
extension_dir =3D c:\apachefriends\xampp\php\ext\
extension =3D php_java.dll
java.log_level=3D4
java.socketname=3D9267
;java.hosts=3D"127.0.0.1:8080 <http://127.0.0.1:8080>"
;java.servlet=3DOn

java.class.path =3D C:\apachefriends\xampp\php\php_java.jar
java.home =3D C:\Archivos de programa\Java\jdk1.5.0_03
java.library =3D C:\Archivos de
programa\Java\jdk1.5.0_03\jre\bin\client\jvm.dll



In C:\apachefriends\xampp\php\ext I have:
JavaBridge.jar
JavaBridge.log
JavaBridge.war
php_java.dll
php_java.jar

I'm no sure if JavaBridge.jar must be in the php directory, or in the
php\ext directory, so I've one in each. I start the jar with the contextual
menu. The only thing that gets to log is:

java.net.BindException: Address already in use: JVM_Bind

but this happen when I start 2 times the jar


I hope anybody can enlightme :)

Yes it solved the problem! Sometimes it's so hard to see obvious 
things....sigh...
Thanks a million for pointing this out. The bridge is really a cool tool.

Hi Mikael,

import != java_require. the import is only syntactic
shugar for the java compiler. The NoClassDefFoundError
means that you have used import at compile-time but
you have failed to add the classes at run-time.


> The server side also requires jpos ISOMsg 

java_require("jpos.jar") doesn't magically make the
classes within jpos available to your own classes. It
makes them available to the PHP/Java Bridge, but not
to the classes within myClasses.jar.

The noClassDefFound2.php test checks this pattern,
please see
http://cvs.sourceforge.net/viewcvs.py/php-java-bridge/php-java-bridge/tests.php4/noClassDefFound1.php?rev=1.2&view=markup

The pattern 

 java_reset();
 java_require("foo.jar"); java_require("my.jar");

must fail because foo is not available to my, but

 java_reset(); java_require("foo.jar;my.jar");

must succeed.


> Nope, sorry made no difference

Can you please set java.log_level=4, re-start the
bridge, run the test and attach the log to a ticket? 
Please see
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233

Hello Jost.
Thanks for quick reply. The bridge is really good stuff, hopefully I can 
get i working for this app as well...

Actually I do require jpos for my classes - in ServerRemote the import 
where hidden by eclipse - they actually look like:
package se.certitrade;
import java.rmi.Remote;
import java.rmi.RemoteException;
import org.jpos.iso.ISOMsg;

public interface ServerRemote extends Remote {
.
.
Sorry about that.

The server side also requires jpos ISOMsg and all other used jpos 
classes (all from the same version of jpos).

Nope, sorry made no difference, maybe something I've missed or don't

Problem loading classes with java_require (Was: [Php-java-bridge-users] RMI problem)

Hi Mikael,

[...]

[...] happens when the lookup method in the php-file
is run

as I understand the above problem ISOMsg is not
available to your classes because you haven't required
it (you have required it for the bridge, but not for
your classes).

This behaviour is intentional, please see the
tests.php4/NoClassDefFound tests. For example the
server part could easily require a different version
of jpos or it could only require the stub classes.

Isn't it possible to require jpos for your classes,
too?

Does

# reset the classloader once
echo '<?php java_reset(); ?>' |/usr/bin/php

<?php
[...]
java_require("jpos-1.4.6.jar");
java_require("myClasses.jar;jpos-p.x.y.jar");
[...]
?>

solve the problem?

If so, this means that the PHP/Java Bridge
documentation is broken. I think I need a hint how to
reformulate the sentence "all interconnected classes
must be loaded by the same classloader".

Jost Boekemeier

[Php-java-bridge-users] RMI problem

[Mikael G. <mi...@oe...>]

Hi!
Having problem when using rmi with php-java-bridge-2.0.8. Trying the 
following php code:
<?php
/*
 * Load Java Bridge
 */
if (!extension_loaded('java')) {
  if (!(PHP_SHLIB_SUFFIX=="so" && 
dl('java.so'))&&!(PHP_SHLIB_SUFFIX=="dll" && dl('php_java.dll'))) {
    echo "java extension not installed.";
    exit(2);
  }
}

$here=getcwd();
java_require("$here/jpos-1.4.6.jar");
java_require("$here/myClasses.jar");

// Get an ISOMsg handle and do something with it
$ISOMsg = new java("org.jpos.iso.ISOMsg"); 
$ISOMsg->setMTI ("0260");


$lookup = new java_class("java.rmi.Naming");
$cekrm = new java("se.certitrade.myServerRemote");
$cekrm = $lookup->lookup("//www.somedomain.net/myServer");

?>

The rmi call passes an ISOMsg object that is part of the jpos-1.4.6.jar 
package. The myServerRemote java looks like:

package se.certitrade;
import java.rmi.Remote;

public interface myServerRemote extends Remote {
   ISOMsg sendTransaction(ISOMsg msg) throws RemoteException;
}

When I try to run the php file I get:
java.lang.ClassNotFoundException: Unresolved external reference: 
java.lang.NoClassDefFoundError: org/jpos/iso/ISOMsg. -- Unable to call 
the method because it or one of its parameters refer to the mentioned 
external class which is not available in the current 
"java_require(<path>)" url path. Remember that all interconnected 
classes must be loaded with a single java_require() call and that a 
class must not appear in more than one java_require() call. Please check 
the Java Bridge log file for details.
        at php.java.bridge.JavaBridge.Invoke(JavaBridge.java:1150)
        at php.java.bridge.Request.handleRequest(Request.java:204)
        at php.java.bridge.Request.handleRequests(Request.java:221)
        at php.java.bridge.JavaBridge.run(JavaBridge.java:233)
        at php.java.bridge.ThreadPool$Delegate.run(ThreadPool.java:20)
Caused by: java.lang.NoClassDefFoundError: org/jpos/iso/ISOMsg
.
.

This happens when the lookup method in the php-file is run. ISOMsg is 
(obviously) already instanciated and available. How do I get around this?

Best regards

/Mikael
