Sounds like one (or more) of your arguments are evaluating to null or generating an error when evalutated.  In this case, the argument would likely be skipped.  Check your undeclared 'tsrm_ls' term.  This might be the cause of the error.

Hope this helps.

Good day all,

I'm having a bit of trouble compiling version 4.1.8 against PHP 5.2.3.
I'm getting the following error:

Hi,

> It just says:

> java.lang.NoClassDefFoundError.

then you're out of luck. Java doesn't have a proper module system, the above error means that you 
have compiled against a different API and than what is available now.

When you get the above exception without any indication which class or package is missing, you 
can't proceed. The only way to solve the above Java error is to step back and read the 
documentation of the Java package, which should list the external package dependencies and their
versions.

I'd prefer to remove the C code entirely.

The PHP code is currently between 2 to 50 times slower than the old C code. 
But this will change with 4.2.0, which adds a client-side cache to Java.inc. 
With this cache the PHP code suddenly becomes 1.2 to 2 times faster than the C code.

Hi Jost,

Thank you for your anwser.I tried your suggestion and it didn't gave me that
error but i still don't get it to work.
It just says:
Cause: java.lang.ClassNotFoundException: Unresolved external reference:
java.lang.NoClassDefFoundError.


This is what i did:

moved libAspriseOCR.so to /usr/lib/jvm/java-1_4_2-sun-1.4.2.13
/jre/lib/i386/client/libAspriseOCR.so
moved aspriseOCR.jar to /usr/lib/jvm/java-1_4_2-sun-1.4.2.13
/jre/lib/ext/aspriseOCR.jar

restarted tomcat and apache

See my code below, Java code is directly copied from the manufactures
website:

/*

The original java code:


import com.asprise.util.pdf.PDFReader;
import com.asprise.util.ocr.OCR;

PDFReader reader = new PDFReader(new File("my.pdf"));
reader.open(); // open the file.
int pages = reader.getNumberOfPages();

for(int i=0; i < pages; i++) {
   BufferedImage img = reader.getPageAsImage(i);

   // recognizes both characters and barcodes
   String text = new OCR().recognizeAll(image);
   System.out.println("Page " + i + ": " + text);
}

reader.close(); // finally, close the file.
*/


// My php5 Code

$aJarFiles[] = "./external/lucene-demos-2.0.0.jar";
$aJarFiles[] = "./external/lucene-core-2.0.0.jar";
$aJarFiles[] = "./external/junit.jar";
$aJarFiles[] = "./external/checkstyle-all-4.2.jar";
$aJarFiles[] = "./external/bcprov-jdk14-132.jar";
$aJarFiles[] = "./external/bcmail-jdk14-132.jar";
$aJarFiles[] = "./external/ant.jar";
$aJarFiles[] = "./external/FontBox-0.1.0-dev.jar";

$aJarFiles[] = "./AspriseJavaPDF.jar";
$aJarFiles[] = "./aspriseOCR.jar";

java_require(implode(";",$aJarFiles));

$file = new Java('java.io.File',"./changes.pdf");
$reader = new Java('com.asprise.util.pdf.PDFReader',$file);
$reader->open();
$pages = $reader->getNumberOfPages();


for($i=0; $i < $pages; $i++) {

   $img = $reader->getPageAsImage($i);
   $ocr = new Java('com.asprise.util.ocr.OCR');
   $text = $ocr->recognizeAll($img);

   print $text;
}


Any idea what's wrong with my setup? i Put everything in a zip if you would
like to take a look:

Hi,


> I've got troubles getting the bridge running over a
> local unix socket

this was default until version 4.1.8. In version 4.1.8
we have temporarily switched it off, since 4.1.8 is
only a thin wrapper around the pure PHP PHP/Java
Bridge implementation "Java.inc".


> php-java-bridge_4.0.8a on
> my Ubunto PC and configured the module in many ways

Do you have the libnatcJavaBridge.so? This is the
library which implements unix domain socket
communication.  It depends on whether your Java 
supports JNI and whether or not your JVM can (and is
allowed to) load a native library.

If not, the bridge reverts to local TCP sockets or
named pipes. 

IMHO unix domain socket communication is obsolete on
modern operating systems. The only exception is
FreeBSD, due to a bug in FreeBSD's local TCP socket
implementation (Nagle's algorithm switched on per
default and PHP doesn't have a way to switch it off).

Jost Boekemeier

Hi,

[loading impure java libraries]

> anybody who knows how to do the trick?

The native part should go into a VM specific library
dir and the Java part into java.ext.dirs.

<?php
echo java("java.lang.System")->getProperties();
?>

should show the location of both directories.

You should  find the reason why the back end has
closed the connection in the log of the back end. 

Probably an OutOfMemoryError or something.

tomcat looks for a JAVA_OPTS environment variable.

Example for Unix/Linux which passes some options to

Hi,

> Will it be a version to which "ZEND API" is not
> supported?

any version is supported. Since version 4.1.8 the
bridge uses only two C level API calls: zend_compile
and zend_execute.


> error: too few 
> arguments to function

My fault, sorry. I forgot to add the TSRMLS_CC to the
zend_compile call. So the bridge currently doesn't
compile with TSRM.

I will fix this in a future version of the C code.

Until then please use the latest stable version 3.2.1
instead. Or please use the pure PHP implementation of
the bridge.

Jost Boekemeier

Hello,

I've got troubles getting the bridge running over a local unix socket
connection. I've installed the Debian package php-java-bridge_4.0.8a on
my Ubunto PC and configured the module in many ways already - including
autom. startup of a bridge-jvm with apache and also the standalone using
 the JavaBridge.jar.

My question:
* where do I set the classpath? When running the JavaBridge.jar? Or in
the java.ini, or in both?
* how can I enable local socket-only connections?

Thanks!

- --------------
Using the standalone JavaBridge.jar started with:

java -Dphp.java.bridge.threads=10
- -Dphp.java.bridge.base=/usr/lib/php5/20060613+lfs/
- -Djava.classpath=[my-classpath] -jar JavaBridge.jar
LOCAL:/tmp/php_java_sock 3 /var/log/php-java-bridge.log

and my java.ini:

extension = java.so
[java]
java.hosts     = 127.0.0.1:9267   ;;does not work without this actually
unused setting! - I only want to use the local socket!
java.socketname = /tmp/php_java_sock

the bridge doesn't use the socket.

I also have troubles with the classpath. I tried to add the classpath in
the java.ini with "java.classpath" and I tried to use -Djava.class.path
instead of -Djava.classpath... when running the jvm. If I specify the
classpath in the ini, phpinfo() shows it, but nevertheless I'm getting:
java.lang.ClassNotFoundException: Could not find
net.immofirst.maut.realestates.RealEstatesTest in java_require() path -
I'm sure that the standalone JavaBridge.jar also requires the CP but has
troubles getting it...

Thanks.

I would appreciate if you could help. Additionally I would interested in
your setup concerning performance. I think sockets should be many times
faster. How does persistent connections work? The initialisation is very
slow - I measured ~300ms/request, 95% goes into connection init - the
first java object instantiation is slow, a 2nd one is much faster...

Cheers,
Andy

I restarted my webserver (running WIMP) and suddenly I'm getting protocol errors when running an extremely simple java program:

<?php
session_start();
require_once("http://localhost:8080/JavaBridge/java/Java.inc");
$systemInfo = new Java("java.lang.System");

echo "Total seconds since January 1, 1970: ".$systemInfo->currentTimeMillis();
?>

This worked before I restarted my webserver so I know it's not an error in the code.

I get the following php error:

[12-Jul-2007 11:55:35] PHP Warning:  fread() [<a href='function.fread'>function.fread</a>]: Length parameter must be greater than 0 in http://localhost:8080/JavaBridge/java/Java.inc on line 1313

and on-screen (in Firefox) the following: 

protocol error: , Invalid document end at col 1

I'm using a Java EE Platform with javabridge.war deployed.

Any help would be appreciated.

Hi,

> the same exception error. We think we have this set

> 
> internet --- Apache LB -- J2EE node 1 -- PHP
> .................|--------- J2EE node 2 -- PHP

this setup doesn't use a remote context factory. 

Do you use a load balancer setup where the DNS server
is changing the official name of the nodes? When the
promiscuous option is enabled, the bridge uses the
official name to connect to itself.


> Is there a parameter that enables the
> RemoteServletContextFactory? 

The remote factory is used when a PHP script running
on a remote host accesses the back end.

Either there's some problem with your setup or you (or
the frame work you use) allocate this factory.

But it is hard to tell, because you haven't raised the
bridge log level. All I see is the exception message
and the stack trace.

Hi Jost,

We tested using the php implementation and we got the same exception =
error. We think we have this set up:

internet --- Apache LB -- J2EE node 1 -- PHP
.................|--------- J2EE node 2 -- PHP
.................|---------...


Is there a parameter that enables the RemoteServletContextFactory? Or =
how do we disable it?

Please let us know,
Thanks,

Hi,

the RemoteContextFactory doesn't initially store a
session factory.


Why is that a remote context factory anyway, do you
run PHP on the Apache instance set up as the load
balancer? This cannot work.

The setup should look like:


internet ---  Apache LB  --  J2EE node 1 -- PHP
.................|---------  J2EE node 2 -- PHP
.................|---------...

or

internet --- Apache LB   --  Apache+PHP 1 - J2EE node

...............|-----------..
