php-java-bridge-users Mailing List for PHP/Java Bridge (Page 88)

Hi,
   
  I've deployed PHP/Java bridge as a Tomcat module. My PHP application which uses it to connect with Java application is deployed to the same server. It works fine now, but the issue I can't resolve now is how to provide MySQL support for my PHP application. 
  It works from Apache but I had problems to connect it with php/java bridge on Tomcat, so I have decided to deploy it on Tomcat. I have tried to add "extension=php_mysql.dll" to the php.ini available on the "..\Tomcat 5.5\webapps\MyAPP\WEB-INF\cgi\php.ini" which is used by my PHP application, but it always crashes. 
   
  Is it possible to connect PHP, Tomcat and MySQL, and if yes, how can I do it?
   
  Thanks 
  Zoran

amazing...

But if you do this more than once, you might get a PermGenSpace or some other OutOfMemoryError.

HI, 
   
  I have resolved this issue too. The problem persist if I use One-Jar to pack my jar file. However, if I turn it of it works fine.

  I have resolved this issue. I have created jar file using Fat-Jar eclipse plugin. I have tested it from command prompt and it works fine. The main class is depths.moodle.MainClass which is executed successfully. However the following code 
   
  require_once('http://localhost:8080/JavaBridge/java/Java.inc'); 
  java_require("moodleLOCMapper_fat.jar");

  $repository=new Java("depths.moodle.MainClass");
   
  generates ClassNotFoundException for depth.moodle.MainClass in java_require() path (complete error code is given bellow.

  Could you tell me where exactly should this jar file reside. I have tried to put it at the same folder as test.php page that use it, or at the "Tomcat/webapps/JavaBridge/WEB-INF/lib". In both case, I got the same error message.

Not really. The only person who could resolve this issue is the person who has compiled the
class or library. You could look at the library docs, which probably include a section which lists
the libraries which must be linked together in order to build an executable. 

Once you know which libraries to link, you can append them to the java_require path or 
copy them to WEB-INF/lib/ and restart the J2EE server.

Although there's nothing wrong with the dynamic loader per se, I'd like to remove it in one
of the next releases. I want to get rid of the class loading problems. If Java users have
(the usual) class loading issues, they should contact their AS vendor, not us.

The directory which contains the myapp web application, yes.

Hi Jost,

Thanks for your reply.  It is certainly possible to copy all of my libraries to WEB-INF/lib.  Infact this has been my behavior once I was able to finally package up myapp.jar (a huge pain - not the jar -cvf etc, but the silly java app I am trying to consolidate here).

So with that in mind, I was unaware that myapp (the web app instance of java) needed to be deployed on the "local" apache document root as well.  It was my understanding that loading a library via:

java_require("myapp.jar"); 

would load the java from the Tomcat instance - and then any calls to such classes would of course execute there.  Like I say - I have done that - but the java_require / autoload still fails.  

For number 3, you indicate copying "myapp" to the apache root, does myapp in that case mean the exploded war, or rather just the PHP myapp - which contains no java binary?

Sorry for the confusion man, I did not get the impression from any documentation that the myapp.jar (in any form) had to be deployed on the apache doc root (or any where else in the apache context) as well.

Thanks,
~tim

yes, this is documented, I think. :)

Isn't it possible to copy all your libraries to WEB-INF/lib?


Basically users should be able to install the bridge with 3 simple steps:

1. Rename JavaBridge.war to myApp.war and add all needed Java and PHP libraries to the
   myApp.war

2. Copy myApp.war to the J2EE autodeploy folder, wait until the directory myApp appears

3. Copy the directory myApp over to the Apache or IIS document root

4. Browse to http://yourHost.com/myApp and run the PHP/Java applications.

Hi,
   
  Thank you for your quick answer. I have tried to resolved what you
 have write about this issue. Regardless I have some experiences with
 Java, I must admit that I'm not familiar with deploying it as JAR files. I
 have tried to google for some pages related to this issue, and I have
 resolved till now that it is related to the problem of how JAR
 references other JARS, and that somethimes it can cause "classnotfound"
 problems, but I didn't found anything that clearly explains how to struggle
 this issue. Could you suggest me some link that could be useful to resolve
 this.
   
  >Java has no "module system". The above message means that there's an
 open reference >which cannot be resolved. 
   
  Could you please be more specific about this "open reference which
 cannot be resolved". In my Java class I don't have anything that could
 cause "org/openrdf/sesame/query/QueryEvaluationException" that is not
 handled from Java (I have attached this class, as well as php file that
 use it, if it could be helpful)
   
  Regards
  Zoran

Java has no "module system". The above message means that there's an open reference which cannot
be resolved. 

Please re-read the README section "Java platform issues" and your Java documentation for details.

Hi,
   
  I found that this error is not connected with libraries used in Java. Rather it has something with proxy, as the error code refere to the Java.inc getProxy function. However, I don't have problem to access other java classes in the same package, as well as to access this class from Java code. Here is the complete error code I got:

The IP is interesting. However, if you want to connect to a back end running on any other
interface than 127.0.0.1, you need to switch on promiscuous mode, even if 192.168.15.62 resolve to
a local address. If you have disabled the loopback interface, please enable it. It is considerably
faster. (In promiscuous mode the bridge switches off named pipe communication, furthermore some OS
switch on Nagle's algorithm if the communication goes through a real network interface).

java_require ("foo.jar") is equivalent to:

  $here=getcwd(); java_require("$here/foo.jar");

Otherwise you must use an absolute path or even a URL, for example:

  java_autoload("file:///c:/foo.jar;http://php-java-bridge.sf.net/baz.jar");



> java_require("http://localhost:8080/JavaBridge/myapp.jar");

Yes, this will work. Since version 4.1.0 the bridge copies
http://localhost:8080/JavaBridge/myapp.jar to file:/{java.io.tempdir}/myapp.jar and rewrites the
URL to use the local file instead.

The bridge tries to load myapp.jar from 1) /usr/share/java, 2) from $HOME/lib/ and 3) from
getcwd()/

you will get the same error, if you start PHP from the console. So this is not an issue with
apache or the php/java bridge.

You need to add GNU Gettext, which might be disabled on Windows. -- I have never used PHP on
windows, so I don't know how to resolve this issue. In the worst case you need to compile GNU
Gettext for windows.

Please see the PHP documentation: http://www.php.net/manual/en/ref.gettext.php and the PHP mailing
lists for further help.

Isn't it possible to copy all your libraries to WEB-INF/lib?


Basically users should be able to install the bridge with 3 simple steps:

1. Rename JavaBridge.war to myApp.war and add all needed Java and PHP libraries to the
   myApp.war

2. Copy myApp.war to the J2EE autodeploy folder, wait until the directory myApp appears

3. Copy the directory myApp over to the Apache or IIS document root

4. Browse to http://yourHost.com/myApp and run the PHP/Java applications.

I think I got it, but I am still having some trouble getting at my custom java classes.  

Despite apache / tomcat being on the same server, it seems promiscuous needs to be on, as well as allow_url_include.

So now I can load the Java.inc via:

require_once("http://192.168.15.62:8080/JavaBridge/java/Java.inc");

But now, I cannot get java_require or java_autoload to get at my classes packaged within my web app.

Do I have to serve up the jar and reference it something like this?

java_require("http://localhost:8080/JavaBridge/myapp.jar");

As I understand it, simply using java_require("myapp.jar") should be able to resolve correctly, considering the context of the Java.inc being within the JavaBridge web app.  In other words, if indeed the Java.inc is setup correctly within the JavaBridge web app, by just doing java_require("myapp.jar"), the PhpJavaServlet will be called upon to load up that class from within its local lib, no?

I am almost there!!

Thanks again,
~tim

Hi Jost,

I see the need for JavaBridge.jar and php-servlet.jar (which includes the PhpJavaServlet).  I see how it is an example web app, that happens to include the required modules for apache <--> tomcat, as well as a couple of handy files such as test.php.

My JavaBridge.war deployment loads fine, and I can access test.php, as well as settings.php.  The JSP's load fine too.  The test.php in particular loads, and has all of the java system properties, as well as the "PHP says that Java says: hello PHP from Java!" and php_java_bridge_Util::type()->VERSION
produces 5.0.0 too.

This suggests that it is working fine on Tomcat - however...

The following test.php on apache:

<?php
require_once("http://127.0.0.1:8080/JavaBridge/java/Java.inc");
$System = java("java.lang.System");
echo $System->getProperties();
?>


produces nothing in the page, and::

PHP Warning:  require_once(http://127.0.0.1:8080/JavaBridge/java/Java.inc) [<a href='function.require-once'>function.require-once</a>]: failed to open stream: no suitable wrapper could be found in C:\\Program Files\\Apache Software Foundation\\Apache2.2\\htdocs\\test.php on line 2

in the apache error logs.

I am sure I am missing an apache setting, but I have been unable to figure out what.

Please help, thanks so much, and sorry for bothering you with this crap.

Hi,

> I am trying to connect my php front-end to my web application in the tomcat backend.

all you need is the PhpJavaServlet in the back end and, if you don't want to call
the back end trough raw PHP fread/fwrite calls, the Java.inc (you can fetch the
Java.inc from the Servlet, or store it locally).

> myBackendApp.war", and that the example uses the
> JavaBridge.jar

It needs JavaBridge.jar and php-servlet.jar and the web.xml which declares the servlet stored
in php-servlet.jar.

You can use the JavaBridge.war as a template; JavaBridge.war is actually just a sample web archive
which contains some PHP examples.


> I will not need any deployed JavaBridge.war
> in order to communicate via the apache php and the tomcat java

Right. Just rename JavaBridge.war to foo.war and change your apache PHP script to

  require_once ("http://localhost:8080/foo/java/Java.inc");

:)


> Building this particular backend war requires quite a bit of effort

Just rename JavaBridge.war to myBackendApp.war, add the libraries and/or PHP files you need
to the myBackendApp.war zip archive and you're done.

Note that the Java files are distributed under the MIT License, so you can do whatever you want
with that code.

Thank you. I have solved this issue, but I'm not sure what was the reason. I have done two things:
   
  1. Remove Zend Core Debugger, as I saw from phpInfo that php.ini is loaded from it instead from C:\PHP. I hope it will not make a problem if I install it again later because I use it for PHP debugging in Eclipse.
   
  2. I have installed PHP again without any extensions
   
  Best regards

Try to disable all PHP extensions. I'd be very surprised if the problem persists.

This has noting to do with the PHP version, the Java bridge version or with Java or with the Tomcat version.

  Do you have some suggestions how can I find what makes a problem? I have already tried with PHP 5.1.0, and different versions of Tomcat (5.5 and 6), and I have always had the same problem.

I thought that maybe I have to change something in Tomcat's configuration files in order to set it to work with PHP.

You are absolutely right about that. I have tried to deploy other PHP application to the Tomcat and I have experienced the same problem, so I suppose that I have not setup Tomcat well to work with PHP.

Both, the bridge and PHP work well i suppose. It's just that PHP crashes. Now you need to find out what or which component makes it crash. Most likely you
have some broken PHP extension in your path which doesn't work anymore with PHP 5.2.

I don't think this has anything to do with tomcat or the php-java bridge or with the tomcat setup. BTW: What do you mean with "I have not setup Tomcat well to work with PHP". It is impossible to do this, unless you have modified the PHP/Java Bridge source code, of course.

  You are absolutely right about that. I have tried to deploy other PHP application to the Tomcat and I have experienced the same problem, so I suppose that I have not setup Tomcat well to work with PHP. 
   
  When I have installed PHP I have set it as Apache 2.2 module. Do I need to configure something in Tomcat in other to use it with PHP?
   
  >Try to use another PHP SAPI instead, i.e. start PHP as an Apache module 
   
  PHP works fine with Apache, but how can I use php/java bridge if I don't use Java application server (i.e. Tomcat)? I can't use pure PHP solution because of performances.

These messages have nothing to do with the PHP/Java Bridge.

Try to use another PHP SAPI instead, i.e. start PHP as an Apache module instead, and/or please
report this bug to the PHP developers. -- I know that the PHP developers have revamped FastCGI in
version 5.1.2, it may break older components.

  A different server api won't make a difference. If PHP is  crashing frequently, there's some problem with the PHP setup (php  module crashing) or with PHP itself. 
  
  For example the following code crashes PHP immediately:
  
  function f () { f(); }
  f();
  
  Most likely the crashes happen due to some deprecated PHP module.
