php-java-bridge-users Mailing List for PHP/Java Bridge

Jost,

Thank you very much for investigating into this.
Thanks, sincerely, for providing and maintaining the PHP-Java-Bridge.

I'm just an ordinary user who's, at times, like now, doing overwork to 
get his tasks done, and it's hard for me to get into details that are 
not complementary to my actual tasks.
I'd like to apologize for that.

Anyways, this:
 > It should occur in all Tomcat versions < 6.
probably ain't exactly true - as I'm still using Tomcat 5.5, and 
upgrading to Ubuntu 7.04 and PHP 5.2 resolved the problems for now.

However, I understand the JavaBridge JARs shouldn't be placed into 
folders shared by multiple Java or Tomcat applications per default.

PHP-Java-Bridge is an amazing piece of software, and I'm really thankful 
you're providing it.

Thanks again, high regards, and best of luck
Robert

With strings, that is.  Is it expected behavior that Integers, Floats,
Doubles, and Longs need to be converted with java_values() before being
used in a PHP context?

For example,

	$integer =3D new Java('java.lang.Integer', 123);

	// displays [[o:Integer]:"123"]
	echo $integer;

	// displays notice "could not be converted to int" and 'not
equal'
	if ($integer =3D=3D 123) echo 'equal'; else echo 'not equal';

	// displays 123
	echo java_values($integer);

	// displays 'equal'
	if (java_values($integer) =3D=3D 123) echo 'equal'; else echo 'not
equal';
=20

Thanks for your help,
Jonathan Abbett

Hi,

first of all thank you very much for the bug report.

We could reproduce the problem that, when the PHP/Java
Bridge is installed in the shared directory, as
described in our FAQ, all classes are loaded via the
same webapp classloader.

We currently don't have a workaround for this tomcat
problem. 

However, this isn't a bug in the PHP/Java Bridge code,
so we won't fix this problem, even though it is
serious.


> What happens is, webapp1 will access the property
> file of webapp2!

Yes. When the JavaBridge.jar and php-servlet.jar are
loaded from the shared web folder, tomcat loads all
classes from the same web classloader. This is almost
certainly a tomcat bug.

> occurs is Ubuntu 6.10, PHP 5.x) the problem does
> *not* occur.

It should occur in all Tomcat versions < 6.


> When I run the same Java classes from a JSP, the
> right properties file 
> will be accessed.

JSP is different. It compiles Java source files to
Java byte code and then invokes the byte code from a
separate classloader. The PHP/Java Bridge could do the
same to work around the above problem.

In the meantime please do not copy the JavaBridge.jar
and php-servlet.jar into the shared tomcat directory.

Jost Boekemeier
