[Php-java-bridge-users] CXF webservice with PHP: Couldn't execute method java_InternalException

[<php...@li...>]

Hello,

I'm new at php-java-bridge (and in java).

I made a class in Java CXF to invoke a webservice with ws-security
(something that is difficult in PHP).

The class is the following in short:

package be.icthealth.ehealth;

import org.apache.log4j.BasicConfigurator;
import org.apache.log4j.Logger;
import org.apache.log4j.Level;
import org.apache.ws.security.handler.WSHandlerConstants;
import org.apache.cxf.endpoint.dynamic.DynamicClientFactory;
import org.apache.cxf.ws.security.wss4j.WSS4JOutInterceptor;
import org.apache.cxf.endpoint.Client;
import java.util.HashMap;
import java.util.Map;
import java.io.File;
import java.net.URL;
//import java.lang.reflect.Method;

/**
 *
 * @author Koen Thomeer, MD, http://koen.thomeer.be
 */
public class Codage {

    /**
     * @param request the class EncodeRequest
     * @return response the class Response
     * @throws Exception
     */
    public Object[] encode(Object request) throws Exception {
        //throw new Exception("test");
        // configure logging
        BasicConfigurator.configure();
        Logger.getLogger("org").setLevel(Level.WARN);

java.util.logging.Logger.getLogger("").setLevel(java.util.logging.Level.WARNING);


        //code that I did leave out//

        // call the Codage
        Object[] response = client.invoke("encode", request);
        return response;
    }
}

The PHP code to call is the following (in short, it is nested in a function;
$input is a PHP Instance):

define("JAVA_PREFER_VALUES", false);
require_once("http://localhost:8080/JavaBridgeWS/java/Java.inc");
try {
$Codage = java("be.icthealth.ehealth.Codage");
$java_input = java_closure($input);
$java_output = $Codage->encode($java_input);
$output = java_values($java_output);
print_r($output);
    } catch (JavaException $e) {
        // in case of an error, process the fault
        echo $e;
    }

The error in the HTTPD log is the following:

Questions:
1. What I'm doing wrong? I don't understand the log.
2. Where I've to put the keystore, properties file, etc?

Thx,

Koen

Re: [Php-java-bridge-users] CXF webservice with PHP: Couldn't execute method java_InternalException

Hi,

your java code has thrown an unchecked exception (error or runtime
exception). After that your php code has tried to set a non-existing
property on it.

Any unchecked exception crossing the container boundary must be declared,
otherwise the behaviour is undefined. Please see our FAQ for details.

Your code contains several problems. Your java object backed by a php
instance doesn't have any public methods. This may or may not be what you
want. And you call a method as if it were a procedure. Won't work, so I
assume that the code you have shown isn't the code you actually use. Either
encode is actually static or the php code you have posted is missing a new
statement.

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...

Hi,

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

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

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.

Re: [Php-java-bridge-users] CXF webservice with PHP: Couldn't execute method java_InternalException

[<php...@li...>]

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,

java_closure reifies an environment for java. It needs a signature.

It does not make attributes available. Those are availabe through methods
declared in the interface.

This explains the error message: You have tried to change a non-existent
attribute. It failed. And the next set! tried to modify the failure report.

Jost Bökemeier

Hello!

   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? 


The current environment. 


   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,

The current environment, which all its procedures renamed to "hello".

  The manual talks
about a keymap: maybe give an example? 
Why is the first argument null?

java_closure(null, array("foo"=>"hello"));

maps "foo" calls to "hello" procedures of the current environment.



You are looking for:

java_closure($phpObj, null, array(java("my.Interface1"), java("my.Interface2")...));
