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

Jost,
  Thanks for compiling for RH 9.0, that solves that problem.  I have a 
problem with PHP seeing the java.so.  When I run a test with, echo '<php 
phpinfo() ?>' | php | fgrep java, I get the folllowing error;

PHP Warning:  Unknown(): Unable to load dynamic library './java.so' - 
./java.so: cannot open shared object file: No such file or directory in 
Unknown on line 0

(I tried the full path also in the php.ini, 
"extension=/usr/local/lib/php/ext/java.so")

What I have done,
1- Tested  and confirmed that I have PHP 4.4.0.  It is running fine and 
serving up web pages.
2- I copied the java.so to the PHP install directory, /usr/local/lib/php/ext
3. I added "extension=java.so" to the php.ini
4 - I copied JavaBridge.jar /usr/opt/tomcat/webapps/WEB_INF/lib
(Is this the correct directory to copy to JavaBridge.jar to?)


Thanks, for the compiled code, and I really appreciate your help!

Jim

Hi Edward,

> This class and all variables/properties belonging to
> that class will never get destroyed? 

the class is garbage collected when your VM has a
class GC and this GC is called. In the standard
configuration (64MB heap) the
tests.php4/binaryData.php test triggers such a GC.

This caching behaviour is intentional.


Everything else (instance variables etc.) is destroyed
after script execution.

It is certainly possible to write a counter using a
static variable so that a method call fails after some
time.  But I don't think this is a good programming
practice. :)

Can you please be more specific?  If possible please
set the java.log_level=4, create a bug report and
attach the log up to the point where the problem
occurs. (please see

Hi,  
I'm also wondering how instances are created and destroyed using java bridge. It seems to me (and from reading the docs) that when instances are created i.e. when u do smth like 
$newinstance=new java_class("java.lang.someclass"); 
This class and all variables/properties belonging to that class will never get destroyed? Is this correct? 
 
This is because I have a class and when I run JavaBridge.jar and execute the class for the first time it always works. But subsequent calls to that class will fail unless I shut down JavaBridge.jar (by terminating javaw.exe from Task Manager) and restart it again. And it also works when I call the java class from command prompt and calling it multiple times does not create any problem.
 
The error that I'm getting is ArrayIndexOutofBounds Exception on one of the variables of the class. I'm just wondering if there is any difference calling java class from command prompt and calling it via the java bridge which can explain this behaviour.
 
Thanks.
