Hi,

[port 8080]
> Caused by: java.net.BindException: Address already in use

if you have a J2EE server running on port 8080, you don't need to start another one.

Hi dominik,

I am not so sure if it is desireable to allow script-specific beans within a IOC framework. Programming one bean in Groovy, the next one in Python and other beans in Java might become a maintanance nightmare.

However, the JSR 223 API allows one to create context-specific script engines, which can be injected into the system and invoked when needed.

Why do you need to refactor internal classes?


> a) which services should be available to php

You can specify the bean configuration in a separate XML file (e.g.: faces-config.xml, ...), why do you need to change the web.xml or the PHP/Java Bridge code?


> b) which classes should php able to load, e.g. java.util.*,

Just attach a context handle to the JSR 233 script engine instance. PHP scripts can fetch their individual context via e.g.: $ctx=java_context()->getAttribute("context");

Hi,

why do you want to switch tomcat off?

Which damage? Just start tomcat again and your PHP/Java code will work again.

Nevermind, i forgot to turn tomcat-apache off.

However, I think to messed up with Php-Java Bridge, as I now can't access the code (and the php-java-bridge page) I used to see if I got the desired results or not. Any way to undo the damage.

Hello,

I'm in the progress of creating an adapted version of the phpJavaBridge for
usage with, currently a Spring Web Context.

The idea behind it is:
I'm moving from a complex php-website to a java powered website. While in
the transition I want to code the java backend
and change the php-implementation piece by piece to use the java backend.
But I don't want the php-code to call whatever it
wants, I just want some specified services (interfaces, classes) available
to php. I want the transition as smooth as possible,
so extracting interfaces/data-methods in my php code which then calls the
services of the java backend. These services will
then be used by the final product of the transition.

For this, I'm currently refactoring some parts of the php-java-bridge to be
more losly coupled and allow the usage of
dependency injection frameworks (spring / guice / seam, etc. )

I want to specify in my Java-Application / servlet-configuration
a) which services should be available to php
b) which classes should php able to load, e.g. java.util.*, java.lang.*;
com.mydomain.app.domain.* etc.

My question now, as I'm planing to publish the resulting work as soon as
finished
a) do you want me to add it to your repository or publish it separatly
b) if you want me to publish it, where & how can I submit it to the
repository
c) are you even interested in these changes? Or do you simply don't care,
because the current code "just works"?

I want to publish this code, as soon as it's finished, maybe even some
middle steps before the final result.
Also I'm trying to create some uml-class diagrams to understand the
relationships between the classes of
the php-java-bridge.. is there a place i can add them to the documentation
part of the project, so to help other
people work with and understand the bridge?



thanks for your answers,
dominik

Hi,

why don't you simply require a functional PHP environment? The bridge can be configured to use the system PHP installation instead of the local PHP binary within WEB-INF/cgi/.


> [PHP_MySQL]
> extension=php_mysql.dll
> 
> And then copy-paste the php_mysql.dll from the dll's

I don't think this will work. The php mysql.so (php_mysql.dll) have been compiled against a specific PHP version and a specific mysql version:

[jostb@carlos ~]$ locate mysql.so
/usr/lib/php/modules/mysql.so
/usr/lib/php/modules/pdo_mysql.so
[jostb@carlos ~]$ ldd /usr/lib/php/modules/mysql.so
/usr/lib/php/modules/mysql.so:
	linux-gate.so.1 =>  (0x00110000)
	libmysqlclient.so.15 => /usr/lib/mysql/libmysqlclient.so.15 (0x0011d000)

The php_mysql driver depends on the version # of the mysql client library (version 15) in this case. A different client library might cause a crash.

I don't think it makes sense to ship a complete mysql installation with each PHP application. However, there are several open-source pure Java-based relational databases which can be easily packaged with your PHP/Java web application.

There is a PDO (PHP Data Object) available for accessing mySql from PHP. 
The easiest way I've found is to  install a LAMP (Linux Apache MySql PHP) 
version and it is pretty much done.  I tend to use Ubuntu.

$st->executeUpdate ("insert into hugo (i, v) values (2, 'second')");
$st->execute("select * from hugo");
$rs = $st->getResultSet ();

$st->close();
$conn->close ();
?>
---------------------------------------------------------

# test
php -d allow_url_include=On mysqlTest.php
=> 
1, first
2, second




      

One of the uses I currently have for Php-Java Bridge is to allow PHP to connect to mySQL. Doing this in Windows is simple, all I have to do is add the following in the php.ini file:

[PHP_MySQL]
extension=php_mysql.dll

And then copy-paste the php_mysql.dll from the dll's that come with the php installer into (apache-tomcat installation directory)/webapps/JavaBridge/Web.INF/cgi. 

What I want to know is if it is an equivalent way of doing this in Red Hat Linux. For instance, instead of say php_mysql.dll, is there a php_mysql.so file out there somewhere?

Thank you in advance for your assistance
-Kevin



      

Jost,

Thanks again for your dedication and amazing support for your phpJava  
bridge project.  I will be working on this over the next couple weeks  
to see how I can pull this all together and get it working.  I will  
do my best to report back (or add some pages to the Web site) on the  
method for running the new 5.4.3 binaries on the OS X Client and OS X  
Server platforms (Both Tiger 10.4 and Leopard 10.5).

Cheers.

Tomcat and Jetty will work out of the box. Tomcat is a little bit easier to handle because of its autodeploy mode.

> the files I need from the JavaBridge package without a PHP

You don't need to extract anything, the deployment tool built into tomcat knows how to handle .war files. It automatically extracts all necessary files into the webapps folder, right after you have copied the .war file into it.

Just copy JavaBridge.war to Tomcat's "webapps" folder, wait one second and that's it.

Jost Bökemeier



      

Jost,

Okay, so I am looking into installing/enabling a servlet engine under  
OS X Server.   That still leaves me with one issue, how can I extract  
the files I need from the JavaBridge package without a PHP fast-cgi?   
Since I only have a PHP binary and the Apache php.so extension.

Is there any other way to get the files I need from the bridge  
package?  Any help appreciated.

Jon
