Hi again,

not really. Version 4.x was a transition towards a pure Java implementation (PHP/Java Bridge 5).

Version 5 has a flag which enables backward compatibility (define ("JAVA_PREFER_VALUES", true)). See our API documentation for details.

Hi,


> java.so

Remove it. 

Whether or not it's a PHP bug or a bug in Apache, I don't care. Simply remove the Java extension and use the pure Java PHP/Java Bridge instead.

The java.so is unsupported since PHP/Java Bridge version 3.2.1.  Please see the NEWS for details.

Just take the java code and replace all "·" with "->", "new xxx" with new java("xxx") and xxx.FOO with java("xxx")->foo to create the PHP code. Please note that the driver must be in the bootstrap classpath, see our FAQ for details. Or deploy the driver via the Bea-/Oracle-/Sun- application server deploy tool.

Yes. Although it is possible to use a pooled resource directly from the servlet, you may need o/r mapping, anyway.

You can find several Java examples which show how to fetch a JNDI resource.

I'm confused how that is relevant to my question. I must not have 
explained my problem sufficiently in my previous post.

We are running 4.3.3 fine now. We were previously running a version 
around 4.0.1.

When we upgraded to apache 2.2.9 using the same java.so we found that 
apache processes were hanging and not exiting. I got a backtrace from 
them that looked like:

This seems to be identical to the discussion I previously referenced.

Things seem to have changed significantly in the 5 stream. We will 
change our code to work with the new stream, eventually but it doesn't 
seem trivial.

Hi

please see our FAQ "How do I enable the Java extension in my php.ini file?"

Hi Jost,

> How can I use the PHP-Java Bridge to connect PHP to MySQL
> using the JNDI connection?

>> Please see the MySQL API for details. An example is here:
>> http://dev.mysql.com/doc/refman/5.0/en/connector-j-usagenotes-basic.html#connector-j-examples-connection-drivermanager

This example is in Java. So I assume that I must create the connection in Java, and then call this script from PHP? How can I call it from PHP?

> $dbh = mysql_connect("java:comp/env/jdbc/TestDB")

>> Mamma mia... :) If you want to access the driver from a EJB session bean, please see our EJB example (http://php-java-bridge.sourceforge.net/pjb/examples/source.php?source=documentClient.php) how to access a session bean.

In this example, would I first need to setup and code an EJB in Java that creates the database connection? I'm using Tomcat, so does this mean I have to use openEJB? Once I have the EJB, do I just call it from PHP using the code example you provided?

regards
Jp

Thаnks Peter, that did the trick: $_POST["txtTest"]
