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

A preview of version 1.0.7 is available:

The binary for RedHat:

http://php-java-bridge.sf.net/php-java-bridge_pre-1.0.7-1.i386.rpm

Source for the rest:
 
http://php-java-bridge.sf.net/php-java-bridge_pre_1.0.7.tar.bz2


The following bugs were fixed: 

* The bridge now generates a proper "class not found"
exception instead of a null pointer exception when the
user path is null.


The following features were added:

PHP 5 support:

* try/catch

* __toString

* object casting

* instead of copying entire hashtables or arrays,
which was necessary in PHP 4, the code now uses the
PHP 5 iterator/array interface.  Your code will work
as before except that you won't get out of memory
conditions when the array's or hashtables are large. 
It is now possible to iterate over everything that
implements Collection or Map, not only hash or arrays.
 Your code will run much faster, too.

* java_instanceof

* java_class: Reference a java class without creating
an instance.

* java_exception

* When the server part receives a SIGTERM or SIGPWR it
will terminate gracefully, i.e. it will not accept new
requests and will terminate when the current
transactions complete.  However, when the second
SIGPWR arrives, it will terminate immediately,
aborting all running transactions.

> I am getting out of memory errors for java.  

You can increase the memory that the JVM uses (32 MB
is standard) with the -Xmx switch.

You must start the JVM as a separate process, though,
because the bridge currently does not pass additional
options to the VM.  

Please type 

  php -i | fgrep java

and paste the java command you see there to the
command line and edit it so that it includes the 

   -Xmx256M  

switch.

For example:

 java -Xmx256M -Djava.classpath... \
               -Djava.library.path=... \
               -Djava.awt.headless=true \
          JavaBridge \
              /tmp/.my_java_bridge_socket 3 ""

Please look up the correct -D values from the output
of the php -i command.  And then edit 
/etc/php.d/java.ini and set the java.socketname to
your socket: /tmp/.my_java_bridge_socket

Another option would be to edit the
"/usr/bin/php-java-bridge" shell script which is used
to start the bridge as a system service.  But you must
be root to do this.


> I couldn't get it started again

Which error message do you get?  Probably the system
/usr/share/java/.php-java-bridge_socket is in use?

I am getting out of memory errors for java.  I am using the java vm
lauched by apache method (I originally used the seperate vm method,
but after I stopped it I couldn't get it started again, and this is a
live server that I cannot reboot).  Can anyone tell me how to modify
the command line that java is started up with so that I can give it a
higher upper limit for memory?

God Bless,

My fault, sorry.  The jxl documentation states that the createWorkbook()
method is in jxl.Workbook, not in jxl.write.Workbook or
jxl.write.WritableWorkbook which I have inferred from its name.

Attached is a testjxl.php which will work.


Regarding the null pointer exception, please read that as a "class not
found exception".  It's actually a bug in the bridge 1.0.6a private
classloader which is trying to access a null java_library_path.  I will
change that null pointer to a proper "class not found exception" in the
upcoming version 1.0.7.  Thank you for reporting this problem.  Here's
the relevant log from /var/log/php-java-bridge.log:

try to load class jxl.write.WritableWorkbook from
jar:file:/usr/share/java/jdom.jar!/
java.lang.NullPointerException
        at JavaBridge$1.findClass(JavaBridge.java:123)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:562)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:494)
        at java.lang.Class.forName0(Native Method)
        at java.lang.Class.forName(Class.java:256)
        at JavaBridge.CreateObject(JavaBridge.java:356)
        at JavaBridge.handleRequests(Native Method)
        at JavaBridge.run(JavaBridge.java:158)
        at java.lang.Thread.run(Thread.java:568)


BTW: The new PHP 5 engine allows introspection, so when the bridge
supports PHP 5, it will be possible to look inside a class and to
interactively pick a certain method or property of a class.

Hi,

I get a "class not found" in 1.0.6 when I try to
access the write.Workbook.  Since we want to write a
workbook we need write.WriteableWorkbook.

I don't know why you get a null pointer instead of a
"class not found" exception. Which version of the
bridge and which version of jxl.jar do you use?

I have tested with 1.0.6a and the jxl and code below:

<?php
java_set_library_path("http://www.jspwiki.org/attach?page=ExcelToHTMLPlugin%2Fjxl.jar");

$fname1 = tempnam("/tmp", "demo.xls");
$file =  new java("java.io.File", $fname1);
$wbClass=new java("jxl.write.WritableWorkbook");
$workbook=$wbClass->createWorkbook($file);

?>

That worked as well as reading a workbook:

$file =  new java("java.io.File", "test.xls");
$wbClass=new java("jxl.Workbook");
$wbClass->getWorkbook($file);
...
$row=$sheet->getRow(1);
$stringClass = new java("java.lang.String");
foreach ($row as $key => $value) {
  print $key . " -> ";
  print $stringClass->ValueOf($value) . "\n";
}

Shouldn't this be 

  $workbookStatic->createWorkbook($file);

The . has a different meaning in PHP, the above code will cause PHP to
look for createWorkbook in the global scope and then append the result
to the object $workbookStatic.

Does this help?

I'm trying to use the jexcelapi http://www.andykhan.com/jexcelapi/ . 
The java code to create a work books looks like this

import java.io.File;
import java.util.Date;
import jxl.*; 

 Workbook workbook = Workbook.getWorkbook(new File("myfile.xls"));

Here is my PHP version
$fname1 = tempnam("/tmp", "demo.xls");
$file =  new java("java.io.File", $fname1);
echo java_last_exception_get();
$workbookStatic = new java("jxl.write.Workbook");
echo java_last_exception_get();
$workbook = $workbookStatic.createWorkbook($file);

and here is my output
Warning: java.lang.NullPointerException in
/var/www/html/ross/oww_testing/stats/carrier_report_old_ross_style.php
on line 14
Object
Fatal error: Call to undefined function: createworkbook() in
/var/www/html/ross/oww_testing/stats/carrier_report_old_ross_style.php
on line 16


FYI line 14 is $workbookStatic = new java("jxl.write.Workbook");

I can't figure out how to run the static function createworkbook.  If
anyone has any tips I'd really appreciate it.

There's an update 1.0.6a available.

The release 1.0.6a replaces the PHP/Java Bridge 
1.0.6. It fixes a bug that appeared when apachectl
was used to restart the bridge.  

This bug only affected the source distribution 1.0.6,
not the RPM package for RedHat Enterprise Linux.
