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

Of course, now that you've said those magic words, my problem has
mysteriously vanished.  The failure situations I described now work!

(BTW, I'm running PHP 5 with Bridge v2.0.7)

Thanks for your help all the same.

Subject: RE: [Php-java-bridge-users] How to pass a "boolean", not
"java.lang.Boolean"?

Hi Jonathan,

> $object->setValue(true);

I could not reproduce the above problem using the
following test code:

public class test {                                  =20
                        =20
    public Object getBoolean(boolean b) {return new
Boolean(b);}               =20
}
<?php                                                =20
                        =20
                                                     =20
                         java_require(getcwd());     =20
                                                 =20
$test =3D new Java("test");                            =20
                        =20
echo $test->getBoolean(true);                        =20
                        =20
echo $test->getBoolean(false);=20

php 4.3.9, bridge 2.0.8.

Can you please set the java.log_level to 5 and attach
the log at the end of the ticket
(http://sourceforge.net/tracker/index.php?func=3Ddetail&aid=3D1379741&gro=
up_
id=3D117793&atid=3D679233)


BTW: Is it possible to upgrade to php5 and bridge
version 3.0.2? PHP5 eliminates this problem altogether
as the bridge no longer needs to coerce the return
values. All the examples you've given should work as
expected, you can even cast java values to boolean or
other php types.=20

Hi Juan,

if I remember correctly, the bridge cannot open a TCP
port in this AS so that it has to use a TCP tunnel for
the entire communication.

[#|2005-12-13T11:43:05.921+0500|INFO|sun-appserver-ee8.1|javax.enterprise.system.container.web|_ThreadID=19;|WebModule[/JavaBridge]
> JavaBridge DEBUG: @5c6110 re-directing to port#
> 9567|#]

The above should not appear, you should get a security
exception instead. Maybe this depends on the OS and
the exception appears too late (i.e. the selected
communication channel turns out to be unusable and the
bridge has no chance to inform the client about this).
 I'll check this.

Do you have the command "truss" installed on your
machine?  If so, can you please open a ticket and
append the result of 

truss php -f testJavaBasic.php 

at the end of the created ticket (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233).

Thank you very much for the bug report.

Jost Boekemeier

Hi Mark,

the syntax for namspace access is different than the
syntax for property access.  For example if you have a
class

public interface php {
 public interface java {
  public class bridge {
   public enum JavaBridge = {UNITS, VOLUME, SCORE};
  }
 }
}

the JavaBridge would be accessed via: 

 $bridge = new
JavaClass('php$java$bridge$JavaBridge');
 echo $bridge->UNITS;

this is to avoid name clashes with the class:

 $bridge = new
JavaClass("php.java.bridge.JavaBridge");

The different syntax makes sense, an I hope the PHP6
developers don't make the same mistake that sun made;
if you compile and place the above php.class into your
classpath, then no java developer can access the class
php.java.bridge.JavaBridge anymore because the java
compiler automatically rewrites the syntax
php.java.bridge.JavaBridge into
php$java$bridge$JavaBridge and stores this into the
.class file.

However, the real fun begins if you compile and place
the following java.class into your classpath:

public interface java {
 public class lang {
  public enum String = {one, two};
 }
}

After that a new java.lang.String() will return the
above enum. -- But I guess this problem is caught by
the java bytecode verifier...

Jost Boekemeier

Hi,

I deployed JavaBridge.war 2.0.8 on Sun Java System Application Server =
8.1 on a Solaris 10 box.
When I execute php -f testJavaBasic.php, I never get a response from the =
AS.
=20
These are the entries in the AS log:

This is testJavaBasic.php:

<?php
    // Obtienen el nombre del OS en el que se esta ejecutando PHP
    $system =3D new JavaClass('java.lang.System');
    $time =3D $system->currentTimeMillis();
    echo $time;
    //$os =3D $system->getProperty('os.name');
    //echo $os . "\n\n";
?>
=20
Any idea about why JavaBridge never response?

Thanks for the help.

Greetings all...
Unfortunately, I have another question about how to pass a variable
without it being converted by the Bridge into something unexpected.

I have a method that accepts a small-b "boolean" as its only argument.
I've tried a few different strategies, but the variable I provide always
ends up a "java.lang.Boolean," and causes a NoSuchMethodException.

Here's what I've tried:

// getBoolean returns a boolean primitive
$boolean_class =3D new java_class('java.lang.Boolean');
$object->setValue($boolean_class->getBoolean('true'));

----

$object->setValue(0);

----

$object->setValue(true);

----

// booleanValue() returns a boolean primitive
$boolean =3D new java('java.lang.Boolean', 'true');
$object->setValue($boolean->booleanValue());

---

$object->setValue((boolean)'true');



No luck with any of them.  Suggestions?

Thanks!
Jon Abbett
