It appears that the problem I was having with fread() errors (which, by the way, Jost, I couldn't find any errors in the logs.  Where would I find this log? Tomcat should report the error, shouldn't it?) has to do with a JavaScript function interfering with Java.  I guess they're so similar in terms of syntax that functions that happen to have the same name clash.  That is what appears is happening with the setCookie function that exists in java.inc as well as many JavaScript based web applications that use cookies.  Of course, I don't have to use JavaScript to set cookies, so I'll be finding a different way to set cookies I need to set.

Hi,

the code pulls the java libraries from a remote server. Furthermore you remove all cached
libraries at the end of the script, probably to emulate the dynamic behaviour which is switched
off for remote URL's.  Fetching jar files from a HTTP url is expensive, especially if 
you don't allow the bridge to cache them.

Please do NOT use the following:

 java_require("http://myServer.com/myJarFile1.jar;http://myServer.com/myJarFile2.jar;...");
 ... execute PHP code ...
 @java_reset(); 
 
In the next version of the bridge I will remove java_reset() entirely and disallow remote
URL's[1].

[1] Neither is documented, so this shouldn't be a problem for most users. :)

there is nothing wrong with it. 

It means that you use an old php_java.dll or java.so in connection with a recent back end.
I have removed all legacy code in version 4.x, so if you use persistent connections and the
php_java.dll, I'd expect this error on the client side. However, you should see a clear exception
message in the back end.

Please use the pure PHP PHP/Java Bridge implementation instead. If you want to use PHP4, which
cannot execute the PHP 5 code contained in Java.inc, make sure to use the latest php_java.dll.

Or use the stable version 3.2.1 instead.

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?

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
