Thanks for the answer.

IMHI, the manual about java_closure() is not always obvious.

ex:

   1.  function toString() {return "helloWorld";};
   2.  $object =
java_closure<http://php-java-bridge.sourceforge.net/pjb/docs/php-api/java/_JavaProxy.inc.html#functionjava_closure>
   ();
   3.  echo "Java says that PHP says: $object\n";

In this example, no arguments are passed in the java_closure() function.
What does java_closure() transform? Only the last object? It is not clear in
the manual.

ex:

   1.  function hello() {return "hello";};
   2.  echo (string)java_closure<http://php-java-bridge.sourceforge.net/pjb/docs/php-api/java/_JavaProxy.inc.html#functionjava_closure>
   (null, "hello");

In this example, I think the function hello() is transformed, because
"hello" is the second argument. It is a good idea, to change the first line
in ... return "helloWorld";}; to prevent confusion with the second argument
of java_closure() (PHP developpers are KISS-thinkers :-)). The manual talks
about a keymap: maybe give an example? Why is the first argument null?

Now, for my case.

What is $input?

In PHP two classes are declared:
class encodeRequest {
    /**
     * @var string
     */
    public $applicationName;
    /**
     * @var array[1, unbounded] of (object)OriginalDataType
     */
    public $originalData;
}

class OriginalDataType {
    /**
     * @var string
     */
    public $id;
    /**&;
     * @var boolean
     */
    public $randomize;
    /**
     * @var string
     */
    public $inputData;
}

$data = new OriginalDataType();
$data->id = 1;
$data->randomize= false;
$data->inputData = "blabla";

$input = new encodeRequest();
$input->applicationName = "WWM";
$input->originalData = $data;

So $input is an instance of the encodeRequest class. I want this PHP
instance be transformed in a Java instance.

I thought that $java_input = java_closure($input); would do the trick?

Sincerely,

Koen

Hi,

> 1) Is it mandatory for the PHP script to be hosted on a web server?

PHP uses a reference counter which cannot collect some cycles. So yes.
PHP runs best when invoked from a WEB-Server or as a scriptlet from a
Java application.

> Can I pass a database connection to PHP

Sure.

It's a java.lang.Object which implements no interfaces. Not very
useful unless your library detects that it is a proxy and directly
calls its invocation handler. Please see the java_closure() API for
details at http://php-java-bridge.sourceforge.net/pjb/docs/php-api/java/_JavaProxy.inc.html#functionjava_closure

In this case your code will work and I have no explanation for this
issue either.

But if your library is smart enough to call $java_input's invocation
handler, please have a look at your PHP code called from the
invocation handler. It probably calls a library method which throws an
unchecked exception.

The problem is simply that an unchecked exception has been returned
from a Java call but not thrown. (You can get around this by setting
JAVA_PREFER_VALUES, but I think you know that).


Be it as it may, if you only want to add a sec header to your soap
request, you can do this in PHP as well. Or implement it in Java and
call the entire method from PHP.

Hi,

I'm brand new to the bridge and just exploring what my options. In my
scenario, I would be using JSR223 to execute PHP script from within Java. I
have two questions:

1) Is it mandatory for the PHP script to be hosted on a web server? Can I
just load it from the file system and execute evaluate it?
2) Can I pass a database connection to PHP? With RhinoJS and JSR223, I can
initiate a socket connection in Java and pass it to Javascript where it gets
used without problem. Can I do the same with the Java/PHP bridge?

Thanks,
Muesli.

Hi,

please see our FAQ entry "Does it support PHP 4?" at
http://php-java-bridge.sourceforge.net/pjb/FAQ.html

Jost Bökemeier

Many thanks for the help!

1. I don't understand the remark:
"Your java object backed by a php
instance doesn't have any public methods."
=> the method is public (but I did forget the 'static').

2. I changed the code of java:

public static Object[] encode(Object request) throws RuntimeException,
Exception {

-> I added static: that was logic
-> I added RuntimeException, like in the FAQ.

But the error stays the same...

Cheers,

*Niju Mohan,*

I am out of the office until 02/24/2011.
