Hi,

[loading impure java libraries]

> anybody who knows how to do the trick?

The native part should go into a VM specific library
dir and the Java part into java.ext.dirs.

<?php
echo java("java.lang.System")->getProperties();
?>

should show the location of both directories.

Hi,

You should  find the reason why the back end has
closed the connection in the log of the back end. 

Probably an OutOfMemoryError or something.

Hi,

tomcat looks for a JAVA_OPTS environment variable.

Example for Unix/Linux which passes some options to
the VM:

export JAVA_OPTS="-Xmx1024M
-Dphp.java.bridge.default_log_level=6"

/opt/apache_tomcat6/bin/catalina.sh start

Hi,

any version is supported. Since version 4.1.8 the
bridge uses only two C level API calls: zend_compile
and zend_execute.


> error: too few 
> arguments to function

My fault, sorry. I forgot to add the TSRMLS_CC to the
zend_compile call. So the bridge currently doesn't
compile with TSRM.

I will fix this in a future version of the C code.

Until then please use the latest stable version 3.2.1
instead. Or please use the pure PHP implementation of
the bridge.

Hello,

I've got troubles getting the bridge running over a local unix socket
connection. I've installed the Debian package php-java-bridge_4.0.8a on
my Ubunto PC and configured the module in many ways already - including
autom. startup of a bridge-jvm with apache and also the standalone using
 the JavaBridge.jar.

My question:
* where do I set the classpath? When running the JavaBridge.jar? Or in
the java.ini, or in both?
* how can I enable local socket-only connections?

Thanks!

- --------------
Using the standalone JavaBridge.jar started with:

java -Dphp.java.bridge.threads=10
- -Dphp.java.bridge.base=/usr/lib/php5/20060613+lfs/
- -Djava.classpath=[my-classpath] -jar JavaBridge.jar
LOCAL:/tmp/php_java_sock 3 /var/log/php-java-bridge.log

and my java.ini:

extension = java.so
[java]
java.hosts     = 127.0.0.1:9267   ;;does not work without this actually
unused setting! - I only want to use the local socket!
java.socketname = /tmp/php_java_sock

the bridge doesn't use the socket.

I also have troubles with the classpath. I tried to add the classpath in
the java.ini with "java.classpath" and I tried to use -Djava.class.path
instead of -Djava.classpath... when running the jvm. If I specify the
classpath in the ini, phpinfo() shows it, but nevertheless I'm getting:
java.lang.ClassNotFoundException: Could not find
net.immofirst.maut.realestates.RealEstatesTest in java_require() path -
I'm sure that the standalone JavaBridge.jar also requires the CP but has
troubles getting it...

Thanks.

I would appreciate if you could help. Additionally I would interested in
your setup concerning performance. I think sockets should be many times
faster. How does persistent connections work? The initialisation is very
slow - I measured ~300ms/request, 95% goes into connection init - the
first java object instantiation is slow, a 2nd one is much faster...

Cheers,
Andy

I restarted my webserver (running WIMP) and suddenly I'm getting protocol errors when running an extremely simple java program:

<?php
session_start();
require_once("http://localhost:8080/JavaBridge/java/Java.inc");
$systemInfo = new Java("java.lang.System");

echo "Total seconds since January 1, 1970: ".$systemInfo->currentTimeMillis();
?>

This worked before I restarted my webserver so I know it's not an error in the code.

I get the following php error:

[12-Jul-2007 11:55:35] PHP Warning:  fread() [<a href='function.fread'>function.fread</a>]: Length parameter must be greater than 0 in http://localhost:8080/JavaBridge/java/Java.inc on line 1313

and on-screen (in Firefox) the following: 

protocol error: , Invalid document end at col 1

I'm using a Java EE Platform with javabridge.war deployed.

Any help would be appreciated.

Hi,

this setup doesn't use a remote context factory. 

Do you use a load balancer setup where the DNS server
is changing the official name of the nodes? When the
promiscuous option is enabled, the bridge uses the
official name to connect to itself.


> Is there a parameter that enables the

The remote factory is used when a PHP script running
on a remote host accesses the back end.

Either there's some problem with your setup or you (or
the frame work you use) allocate this factory.

But it is hard to tell, because you haven't raised the
bridge log level. All I see is the exception message
and the stack trace.

Hi Jost,

We tested using the php implementation and we got the same exception =
error. We think we have this set up:

internet --- Apache LB -- J2EE node 1 -- PHP
.................|--------- J2EE node 2 -- PHP
.................|---------...


Is there a parameter that enables the RemoteServletContextFactory? Or =
how do we disable it?

Please let us know,
Thanks,

Hi,

the RemoteContextFactory doesn't initially store a
session factory.


Why is that a remote context factory anyway, do you
run PHP on the Apache instance set up as the load
balancer? This cannot work.

The setup should look like:


internet ---  Apache LB  --  J2EE node 1 -- PHP
.................|---------  J2EE node 2 -- PHP
.................|---------...

or

internet --- Apache LB   --  Apache+PHP 1 - J2EE node

...............|-----------  Apache+PHP 2 - J2EE node

...............|-----------..

Thank you for your answer.

We have a Java J2EE backend and in front of it we use a PHP based CMS.
We used to use simple HTTP requests to transfer the HTML from our
backend to the PHP frontend (both on the same server). After some tests
with the PHP-Java bridge it was clear that this solution is much faster.

As I understand the HTTP tunnel is deprecated and in the future may even
stop working in the development version.

For testing the frontend on a local computer, I have created a mockup,
so the problem has been solved already.

Hi,

[please excuse the delay]


> of tomcat are running within 15 to 30 min one of the
> tomcat instances stops responding and a browser

I could reproduce something like this when running
2700 instances of the sessionSharing.jsp. The reason
for the failure was an OutOfMemoryError in the session
replicator.

> We have not found exception in the log files

I have started both instances with catalina.sh run,
the error message appeared in the console window.

However, I have attached the proposed tomcat cluster
howto that someone has asked for:

----------------------------------------------

Ho do I set up a tomcat cluster?

Download tomcat 5 or higher, a Java JRE 5 or higher
and the PHP/Java Bridge 4.1.5 or higher.

The following example uses two nodes running on two
machines called "carlos" and "diego". The web server
is running on a third machine which has full access to
both nodes (at least it needs access to the ports from
the range [9267, [9367).

On all nodes: Extract the tomcat distribution into a
directory.

On "diego" add the following to conf/server.xml:

    <Cluster
className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
      channelSendOptions="8">
      <Manager
className="org.apache.catalina.ha.session.DeltaManager"
        expireSessionsOnShutdown="false"
        notifyListenersOnReplication="true"/>
      <Channel
className="org.apache.catalina.tribes.group.GroupChannel">
        <Receiver
className="org.apache.catalina.tribes.transport.nio.NioReceiver"
        address="diego"
        port="4000"
        autoBind="100"
        selectorTimeout="5000"
        maxThreads="6"/>
      </Channel>
    </Cluster>

On "carlos" add the following to conf/server.xml:

    <Cluster
className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
      channelSendOptions="8">
      <Manager
className="org.apache.catalina.ha.session.DeltaManager"
        expireSessionsOnShutdown="false"
        notifyListenersOnReplication="true"/>
      <Channel
className="org.apache.catalina.tribes.group.GroupChannel">
        <Receiver
className="org.apache.catalina.tribes.transport.nio.NioReceiver"
        address="carlos"
        port="4000"
        autoBind="100"
        selectorTimeout="5000"
        maxThreads="6"/>
      </Channel>
    </Cluster>

Copy the "JavaBridge.war" into the "webapps" directory
on "diego" and "carlos" and start both nodes. For
example with the command:

    JAVA_OPTS="-Dphp.java.bridge.promiscuous=true"
JAVA_HOME=/opt/jdk1.5 bin/catalina.sh run 

Start the web server on the third computer "timon".
For example with the command:

    apachectl restart 

Create a PHP script called "sessionSharing-diego.php"
and copy it into the web server document root (usually
"/var/www/html" or "~/public_html") on "timon":

    <?php
   
require_once("http://diego:8080/JavaBridge/java/Java.inc");
    $session = java_session();
    if(is_null($session->get("counter")))
      $session->put("counter", new
Java("java.lang.Integer", 1));

    $counter = java_values($session->get("counter"));
    print "HttpSession variable \"counter\":
$counter<br>\n";
    $next = new Java("java.lang.Integer", $counter+1);
    $session->put("counter", $next);
    ?>

Create a PHP script called "sessionSharing-carlos.php"
and copy it into the web server document root (usually
"/var/www/html" or "~/public_html") on "timon":

    <?php
   
require_once("http://carlos:8080/JavaBridge/java/Java.inc");
    $session = java_session();
    if(is_null($session->get("counter")))
      $session->put("counter", new
Java("java.lang.Integer", 1));

    $counter = java_values($session->get("counter"));
    print "HttpSession variable \"counter\":
$counter<br>\n";
    $next = new Java("java.lang.Integer", $counter+1);
    $session->put("counter", $next);
    ?>

Start a web brower and remove all cookies

Browse to http://timon/sessionSharing-carlos.php and
check the generated cookie. It should have the key
"JSESSIONID", host attribute "timon" and the path
attribute "/". The value should be "1". Click on the
browser refresh button to increase the value.

Use the same browser window and navigate to
http://timon/sessionSharing-diego.php and check if
there is still only one cookie with the same
attributes as before. The value should be "3"

Use the same browser window and navigate to
http://timon/sessionSharing-carlos.php and check if
there is still only one cookie with the same
attributes as before. The value should be "4".

Switch off "diego" and start it again.

Use the same browser window and navigate to
http://timon/sessionSharing-diego.php and check if
there is still only one cookie with the same
attributes as before. The value should be "5"

Switch off "carlos".

Use the same browser window and navigate to
http://timon/sessionSharing-carlos.php and check if
you get an exception.

Start "carlos".

Use the same browser window and navigate to
http://timon/sessionSharing-carlos.php and check if
there is still only one cookie with the same
attributes as before. The value should be "6"

Please see your HTTP server documentation how to set
it up as a load balancer. This differs from the
architecture described above in that the load balancer
forwards the requests to the nodes and the nodes run
PHP using the FastCGI mechanism.

if you switch off both, the Pipe- and the
SocketContextServer, the C implementation will
continue to send HTTP PUT requests.

However, this path is quite old. It still works, but
it is slow. Isn't it possible to use standard web
services to access a remote service?

Hi,

[please excuse the delay]

which implementation of the PHP/Java Bridge do you
use?

I have tested the pure PHP implementation and could
not reproduce this problem when running two cluster
nodes on the same machine.

Can you please open a problem report and attach the
following information to the ticket:

* which implementation do you use (C or PHP)

* if C: are persistent connections enabled

* if C: which PHP version

* the log from the back end (please start the nodes
with -Dphp.java.bridge.log_level=5)


We'll look at this issue asap.

Your scripts must contain a statement:

  $session = java_session()

at the beginning of your scripts (as usual).

If you use the pure PHP implementation, the PHP client
will first contact the servlet, obtain a session from
there and then switch to a (persistent-) Pipe- or
SocketContextServer .

The C implementation currently does not support a
cluster environment. As a workaround please use the
pure PHP implementation. Or, if you must use PHP4,
switch off java.persistent_connections in the php.ini
file and make sure that either the Pipe- or
SocketContextServer can be reached: The C
implementation uses HTTP PUT requests if it doesn't
receive a Servlet -> ContextRunner redirect. This code
is broken since version 2.0.8 and might be removed
from the C implementation.

Jost Boekemeier

Thank you very much again.

Hi,

since version 4.1.4 the bridge doesn't use a
JarURLConnection anymore. This means that the
DynamicClassLoader can now track changes in remote jar
files.

The problem was that, in order to load classes from a
remote jar file, java had to copy it into a local temp
directory and use the copy for all further operations.

The standard jar loader creates a temporary copy and
deletes it when the VM terminates. This behaviour
makes the DynamicClassLoader unusable for remote
files.

I have added a connection class which fetches the
remote jar file and caches it until the associated URL
is finalized. Please see 

http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bridge/server/php/java/bridge/DynamicJarURLConnection.java?view=markup&sortby=date

for details.

(I haven't tested it very much, but the algorithm
should work).


Furthermore the bridge now contains a full-featured
HTTP server which gets started by double-clicking on
JavaBridge.jar. 

It cannot handle JSP pages, but it can handle
server-side scripts, including python, php, bean shell
and jscript. 

The server uses the standard discovery mechanism to
load the script implementation. This means that you
can add further script implementations by adding them
to java ext dirs.

Jost Boekemeier

Hi,


> Using php-java-bridge v 4.1.1

Please try version 4.1.2. Or use the latest stable
version, which is PHP/Java Bridge 3.2.1.

Version 4.1.1 had problems with persistent
connections; We have rewritten the C extension so that
it uses the same path as the pure PHP implementation.

Yes, version 4.1.1 had serious problems when used with
the C based extension (java.so or php_java.dll).

The C extension is really hard to maintain, but we
have decided to keep it. The pure PHP implementation
is a little bit slower as it always connects to the
servlet to obtain a context factory and then switches
to one of the ContextRunners. But its logic is easy to
understand and very robust.

In versions 4.1.2 and above the C extension should
work again.

Hello,

I'm using php-java-bridge 4.1.2 (downloaded the binary release).
Then I copied both PhpJavaServlet.jar and php_servlet.jar to the lib
directory in my J2EE WAR, I also copied the PHP resources from the /java
directory (for the pure PHP implementation). I'm using JBoss 4.0.4 as
application server together with Java 1.5_11. I modified my web.xml to
expose the PhpJavaServlet.

This all works really great and very fast using PHP4 with the (legacy)
java.so module and also with PHP5 and the pure PHP implementation.

But now I want to connect to the same PhpJavaServlet from my local
computer to this remote server (for testing purposes). How do I enable
HTTP tunneling? As far as my knowledge goes, I cannot use sockets to a
remote server.

I tried to use "promiscuous" and also messed around with
"php.java.bridge.no_pipe_server", but this didn't work out. Looking at
the source code I also cannot tell when HTTP tunneling is used. It
should call the method named "handleHttpConnection()", but it is never
called.


My question, is it possible to connect to my remote server from my local
computer? (I do not care about the speed, just for testing).

Any ideas?

Using php-java-bridge v 4.1.1 built from source on a 64-bit SUSE 9 Linux
box.  Running PHP 4.3.4, Apache 2.0.52.  JRE is 1.4.2_11, from SuSE (which
I'm pretty sure is Sun Java).

 

Just started using php-java-bridge, and so far have had mostly success,
except for one annoying problem that could be a deal-breaker.
Occassionally, when I load a page that actually uses php-java-bridge on
Firefox, I get a blank page.  I can reload, and it comes up fine.  When I
get the blank page, I can view source and see all of the source for the page
I requested is there.  I don't have this problem on IE6.

 

First thought is that this is a Firefox problem, what does php-java-bridge
have to do with it?  Well, I never saw the problem before, and I can load
pages using php that do not actually use any of the php-java-bridge
functionality, and they NEVER fail.  My thought is that the process does not
exit cleanly during some of the clean-up, and that Firefox chooses to not
display the information it has so far whereas IE does.  I've heard some
reports of crashes/segfaults during the clean-up process, but always PHP 5,
and we're using PHP 4.

 

Looked in the logs and found some segfaults in the apache logs, but often I
see the failure behavior without a segfault.  The only thing I see happening
regularly when there is a failure are some Samba warnings (have no idea why
this would be using Samba at all-it doesn't access any files off of the
local fs).  However, those warnings also occur when it does NOT fail (though
not when I load a page that does not use php-java-bridge), and we have been
seeing those warnings come up in various contexts for years without any
manifest problem.

 

So, I think the segfault and the samba warnings may be red herrings.

 

Any ideas?

 

Michael.

Thank you very much for your suggestion to set the =
-Dphp.java.bridge.promiscuous=3Dtrue I realized I was not setting that =
parameter in the correct place in the windows service and that is why it =
was not taking place.

Now, it is still not working. When I attempt to access 	=
Tomcat5.5\webapps\JavaBridge\test.php I get the following error:
