The following bugs were fixed:

* The JavaBridgeClassLoader now extends from 
URLClassloader, so that custom code written against 
URLClassloader works as expected.

* A bug in the new 2.0 protocol was fixed which 
ignored array values when the bridge run in PHP4.
See test tests.php5/arrayArray.php4 for details. 

* A bug in the new 2.0 protocol was fixed which 
confused empty arrays with "null values".  See test 
tests.php5/showResources.php for details. 

* The default __tostring and cast <String> was 
changed. Java objects displayed this way start 
with "<Class:".  This change was necessary for 
PR1170405.  See test
tests.php5/printToOutputStream.php for details.


New features:

* MONO supported (experimental).  
You can compile JavaBridge.jar into a .NET 
executable, for example with the command:
  ikvm.exe JavaBridge.jar 
and start JavaBridge.exe as usual.  The bridge will
automatically join the MC group and responds to both
.NET and Java queries (i.e. java scripts may be 
executed by a .NET VM, but not the other way 'round).

* Fail over and load balancing
supported(experimental).
The bridge sends out a multicast to all VM's which 
have joined the MC group and selects the first VM 
which has a load <20.

Hi,

what you describe is a bug in the new 2.0 protocol.  Your second example
should create a PHP Array if run in PHP 4.  (It works correctly in PHP5,
see tests.php5 folder).

I am going to fix this asap.  In the meantime please use PHP 5 or use
the PHP/Java Bridge 1.0.8 for your tests.


Thank you very much for reporting this bug.

Hi,

sorry I need help once more, because I don't get the answer for my question
even though I tried it for half a day

How can I access the fields of a returned array?

Example (here the number of the fields are known before execution, but in my
real application the number of the fields are known not until execution):

import java.util.*;
import java.sql.*;

public class javatest {

  public javatest() {
  }

  public static Object test1(String testvar) {
    Object testobj = null;
    testobj = new Object();
    testobj = testvar;
    return testobj;
  }

  public static Object[] test2(String testvar1, String testvar2) {
    Object[] testobj = null;
    testobj = new Object[2];
    testobj[0] = testvar1;
    testobj[1] = testvar2;
    return testobj;
  }
}


<?php
  $testvar = new Java('javatest');
  $testobj1 = $testvar->test1("TestAusgabe1");
  print $testobj1.' <br>';
  $testobj2 = $ testvar ->test2("TestAusgabe2.1"," TestAusgabe2.2"));
  print $testobj2[0].'  <br>';
  print $testobj2.'  <br>';
?>

Output:
TestAusgabe1
T
TestAusgabe2.2

So $testobj2 is not an array but a string which has the second value of
test2.

I have tried several things to access the first field of testobj2 but
without access. So I would be very happy if you have an advice what to do.

Many thanks in advance

Michael

The java code (usually) runs in a J2EE application server and the PHP
scripts (usually) run in the HTTP server domain.  The PHP/Java Bridge
connects those two components.  I.e. it is a server technology, it
cannot run in a client browser or on a client machine and it cannot be
used as a replacement for java applets or ECMA script.

If I use the php-java bridge, will my Java code be run in the applet
sandbox?  I want to pull machine-specific info from my users so that i
can identify unique machines in a way not easily spoofed.

Also, this will prompt the user to allow the application, correct?

Hi Jost,

many thanks for your very fast answer and the workaround!

Regards
Michael

P.S.: The Php/Java Bridge is a great project!

Betreff: Re: [Php-java-bridge-users] CLASSPATH once more

Hi,

it depends how you search for the resources.  Currently only
findResource() is available.=20

Since the JavaBridgeClassLoader is currently not(!) an URLClassLoader,
the ShowResources.listResources() function ignores it.  I will probably
change that for the next version 2.0.5.


As a workaround please copy your jar file(s) to $JAVA_HOME/jre/lib/ext,
for example to

   /opt/jdk1.5/jre/lib/ext

and re-start the bridge.

After that your jar(s) are loaded via the standard class loader.

Dear Experts!

Yesterday I installed the Java-Bridge (ver. 2.0.4) and everything works fine
so far, but I'm struggling with JAR, CLASSPATH or whatever the problem
generates.

With PHP I call a Java-Class (UserClass1) stored in a JAR-file
(jarfile.jar). In PHP I "link" to this JAR file with:

java_set_library_path("/srv/www/htdocs/user/jarfile.jar").

In that JAR-File there is also a file (Data.File) stored, which is called by
another JAVA-Class (UserClass2) with java.net.JarURLConnection and
ClassLoader-Function. UserClass2 is called by UserClass1. 

This works fine by calling it direct with java (java -classpath jarfile.jar
UserClass1) but by using it with the Java-Bridge it does not work.
Here the UserClass2 can't find the Data.File. To get an idea, what's going
wrong, I inserted a further class (ShowResources.class)
(http://forum.java.sun.com/thread.jspa?threadID=286026&messageID=3034420)
which shows me ALL accessible resources (output in the
/var/log/php-java-bridge.log). ShowResources is called in UserClass2 before
trying to load Data.File.
With this information I saw, that only the classes of JavaBridge.jar and the
java-classes are accessible by the ClassLoader, but my jarfile.jar is not. 

So I tried to reference it in the php.ini with the setup-variable
java.classpath (I also tried java.class.path) but without any access. I also
saved the jarfile.jar under /usr/lib/php/extensions. Nothing is working;
everytime only the above mentioned classes are available.

So I'm at my wits end and I hope you can help me to solve this problem.

Many thanks in advance

Michael

A number of people reported that binary data isn't
send correctly in version 2.0.1.  There are a number
of bugs regarding this which 2.0.2 attempts to solve.

To the best of my knowledge 2.0.2 should handle binary
data as well as 1.0.8.  If there are still open
issues, please send a PR to the mailing list of open a
ticket.

There are no user-visible changes from version 1.0.8 to version 2.0.1.


However, the server part is now written in pure java. The new XML
protocol is at least two times faster than the old binary protocol based
on java JNI.  Furthermore it is now possible to deploy the
JavaBridge.jar into WebSphere or WebLogic and to invoke java enterprise
applications from PHP scripts without writing SOAP or EJB interfaces.

The XML protocol makes it easy to write bindings for perl, phython or
other script languages.  The examples/clients directory contains a
sample written in the programming language Scheme which connects to the
server, asks for System.getProperties() and transforms the resulting XML
document via a XSL into a HTML table.

Two experimental features were added:

1. session sharing, see tests.php5/session.php

2. the bridge can connect to a number of backends running the server
part of the bridge.  If one backend is unavailable, the bridge uses the
next available backend.  Please see the documentation for java.hosts for
more information.
