Hi,

> an update on the fread() errors below: 

a short read or a "protocol error" means that something went wrong in the back end; the back end
has simply closed the connection.

You should find the reason for the short read in the log of the back end.

Hi,

the ISAPI requires a running IIS webserver, right?

Why don't you install PHP into IIS and then use the following code:

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

To connect the PHP instances running in your IIS server with the tomcat J2EE back end?

Jost Boekemeier

Hi,

[eval calls itself until a stack overflow occurs]
> Exception in thread "main" java.lang.StackOverflowError

I think version 4.2.0 have had such a problem. I could not reproduce this in version 4.2.1, but
this may well be a problem due to a change in the JSR223 API.

Which one do you use, the API shipped with the bridge or some other API?

Hello,

I'm currently using the PHP javabridge to use lucene together with PHP5.
I developed our application and everything looked fine. Some stress test
pointed me in the direction to use Tomcat as a servlet engine. we had an
4time speed increase after that. Everything looked fine till it went in
production.
The setup Tomcat and Apache started acting weird. Sometimes the code throws
this error while other javabridge parts of the page work:
Fatal error: php_mod_java(98): Call object is null: The connection to the
current back end doesn't exist anymore; probably the current back end has
been restarted w/o restarting the front end.
the problem is basically that the production server is not stable. If anyone
has a suggestion how to make this setup reliable and have some suggestions
to tune apache/tomcat/javabridge/lucene?

Greets,

Gilbert

Hi Jost!

As you suggested, I opened a ticket and appended the detailed PHP-Java Bridge log (level = 5) at the end of that ticket.  I also included additional information (e.g. my environment and the way I use PHP-Java Bridge code) in there.

http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233

I hope you can help me find out why my code executes very slowly, and get ideas on optimizing PHP-Java Bridge code usage.

Thank you very much!

Regards,

Filip

an update on the fread() errors below: 
It started failing on the following computer

http://192.168.0.5:8080/JavaBridge/test.php

after I'd changed a webpage that I've been developing (that makes use of the bridge) and clicked refresh.  Thus, it must not have to do with which computer is used.

I found that deleting cookies makes it work again for some reason, so the problem must have something to do with cookies or the cache.  Does the java bridge use cookies?  if so, can it be configured not to?

I want to run the javaBridge's pure php implementation
I do not want to run php as a CGI, but rather use my already running ISAPI php

When I first place the javaBridge.war file in Tomcat's webapps directory, it works fine regardless of which machine I used to access 
http://localhost:8080/JavaBridge/test.php

However it does use CGI/FastCGI version of php (5.2.1) which is obviously not the ISAPI php instance I want it to use.  It does list C:PHP5\php.ini as the php.ini file that was loaded, so it must be finding the php folder.

Also, when I restart the computer, a request to http://localhost:8080/JavaBridge/test.php
from the localhost will fail with

Warning: fread() [function.fread]: Length parameter must be greater than 0 in C:\Inetpub\wwwroot\JavaBridge\java\Java.inc on line 884
protocol error. , Invalid document end at col 1

However, if I go to the same page from a different computer
for instance: 
http://192.168.0.5:8080/JavaBridge/test.php
the test completes successfully

So, I have two questions, how can I configure the bridge to use my ISAPI php instance, and why can I only run java from a computer that's not the server?

Thank you for your time.
