[Php-java-bridge-users] Getting back null-object from new Java(...) - how to debug this?

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

I am using php/java bridge 3.1.8. I am having the interesting case that in
my PHP code I do a

      $classpath='...';
      java_require($classpath);
      try {
            $var=new Java('class.name.here');  // the constructor has no
paramete
      } catch(JavaException $exeption) {
            throw new Exception('Java-exception creating object of class
"class.name.here": '.$exeption);
      }
      if ($var) {
            // using the object...
      } else {
            echo 'got a null object... :-( ';
      }

Initially I was getting misc. ClassNotFound-Exceptions until I got my
classpath right. The classpath seems to be OK now, but now I am NOT getting
any JavaException but I get back a null-object, i.e. I am falling into the
echo ... statement in the above snippet.

How can I figure out, what's going wrong here and why???

Hi,

you're right that new Java(...) cannot return NULL.

> How can I figure out, what's going wrong here and

You can look at the protocol level. Either set the log
level to 4 or above or, if you use linux, type:

strace -s 1024 php yourPhpScript.php >error.log

You will see something like:

--> <C p=... v=...>...</C>
<-- <O v=.../>


Which PHP version do you use, btw?

Hi,


Please open a ticket, please use

and attach the log of the bridge there.


We'll check this issue asap.

[Php-java-bridge-users] Does php java bridge 3.2.1 support java 1.5 generic syntax?

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

Hi
  For my application, most of the methods use generic as a parameter or
return value (e.g. List<Foo>).  Does the bridge support generic systax.
If it does, could I have a link to the document?

Could the syntax be like?
new java("java.util.List<String>");

Re: [Php-java-bridge-users] Does php java bridge 3.2.1 support java 1.5 generic syntax?

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

Hi,

Yes, generics (implemented as erasures) are no problem
for the bridge. Please see our FAQ for details. Real
generics, as proposed by the Rice people (which could
be the base of a proper java module system) need some
adjustment within the bridge code.


> Does the bridge
> support generic systax.

You probably mean "does the bridge support java
generics"? Yes, it does. 

Does it support a generic syntax? No. Java only
supports generics on its surface, the byte code below
is still the same as in java 1.4.

Implementing a syntax transformer (something like
Scheme's define-syntax) for PHP is outside the scope
of the PHP/Java Bridge. 


> Could the syntax be like?
> new java("java.util.List<String>");

The syntax is:

  new java("java.util.List");

Are you sure? IMHO the PHP/Java Bridge only supports
PHP 4.3.2 and above. 

Or do you use some other PHP implementation?

Ooops - sorry - my error: you had asked for the PHP version not the
PHP/Java-bridge version: I am using PHP 5.1.6.

Re: [Php-java-bridge-users] Getting back null-object from new Java(...) - how to debug this?

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

Sorry, but that instruction was to terse for me. How/where exactly do I set
that protocol level so that I can monitor what is going on?

I am running the PHP/Java bridge 1.3.8 on XAMPP v1.5.4a on a Windows XP box
and I enabled the PHP/Java bridge by placing the files
"WEB-INF\lib\JavaBridge.jar" and "WEB-INF\cgi\java-x86-windows.dll"
(extracted from the file "JavaBridge.war") into C:\Program
Files\xampp\php\ext (the latter under the name "php_java.dll" and adding a
line "extension=php_java.dll" to php.ini). That's at least how I learned to
install and enable the php/java bridge...

-------------------------------------------------

The "NCI-ctor()" line (about 20th from bottom) comes from the constructor,
which reads:
      ...
      public NCI() {
            System.out.println("NCI-ctor()");
      }
      ...
and since it's the only thing the constructor does, I would assume that it
also completes.

That means, it is the returning of the object that must fail, or how could
I otherwise get a null back from the constructor?

But the line
...
Result [Object 2059172540 - Class:
demo.NCI:ID1344884777:LOADER-ID1560567044]
...
(seventh line from the bottom) suggests that there actually IS some object
returned, so why does the PHP-code then obtain a null???

Really puzzled!

Re: [Php-java-bridge-users] Getting back null-object from new Java(...) - how to debug this?

According to the protocol you use the following code:

$obj = (boolean) new java("demo.NCI");

The result of the cast is true.

<-- <B v="T" i="63bf1c4"/>


At least on protocol level there's nothing wrong with
your code; you've casted the result object to a PHP
boolean value.

I don't know where the boolean cast comes from and why
you or the PHP interpreter confuses the PHP boolean
value with a PHP null object.

Which PHP version do you use? And how exactly does the
code look like?  Note that PHP sometimes uses implicit
casts, depending on the context, for example "$obj"
implicitly casts $obj to a PHP string value.

Re: [Php-java-bridge-users] Getting back null-object from new Java(...) - how to debug this?

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

Gee (blush) - how embarrassing: I had been looking at this code snippet at
least a hundred times now and in the end it turned out, that my condition
actually read

      if (!$var) { ...

instead of:

      if ($var) { ...

Somehow my eyes and brain always ignored to see that '!' between the '('
and the '$'

It's all up and settled now! Sorry for the bandwidth abused,

[Php-java-bridge-users] Log4j.properties setting and eclipse debugging

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

Hi,
  What is a proper way to set (incoporate) my application
log4j.properties file in java bridge?  As I know log4j properties are
set just once; since it was set by java bridge, it ignored my own
log4.properties. =20

Could I use eclipse to debug my code and inspect the values at the point
where the bridge invoking a method in my app? Currently, my backend is a
standalone app.

Thanks for your time

I assume "log4j.properties" is some kind of
configuration file for the "log4j" java library. Such
config files belong to a dedicated config directory
(please see your J2EE server for details) or into the
classpath, for example php.java.bridge.base/lib
(usually: $HOME/lib).

Yes. The PHP/Java Bridge has been developed this way.

I searched and found one of your post in the archive mail,  I wonder =

The JavaBridge.war contains a log4j.jar library. This
library is responsible for this behaviour. I will
remove log4j from the war file.

[Php-java-bridge-users] setting php max_execution_time

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

After recompiling and install java bridge on my linux box, I no longer
find the entry max_execution_time in the php.ini file.  When visiting
phpinfo.php, I do see the value of max_execution_time, default to 30
seconds, which meant phpinfo.php has picked up this value somewhere.
Which file should I use to set value for max_execution_time?   =20

Re: [Php-java-bridge-users] setting php max_execution_time

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

Hi,

> After recompiling and install java bridge on my

well, the PHP/Java Bridge doesn't change your php.ini
file. 

If entries have changed, you must have changed them
yourself (probably through some scripts). -- The
source distribution contains a install.sh script,
which checks if your PHP installation supports a
config scan dir, and if it doesn't, it asks you if it
should write a new config file. It saves the old one
of course.

In any case, this isn't a problem with the PHP/Java
Bridge or its setup.
