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

Yes, you're right. I've reviewing all the code again.the difference was
this:

In the first code I do this:

$i=3Dnew java("java.lang.Integer",1);
$i=3D1;
$Cliente=3D$h->get($i);
echo "Cliente:".$Cliente->toString();

see that line in red, I didn't post it in the previous mail :(

now I understand why didn't work. When I do "$i=3D1" I make the $i a long. =
So,
the only way that we can handle Integer is with the java constructor.

Hi Jost

Yes, HibRepository.java is my class. Let me double check on the config
properties

this sounds as if some config properties are missing.

Is HibRepository.java one of your classes?

Shouldn't java autobox/autounbox Integer to int and vice versa? It will
if you are using java 1.5 at least.

can you please set the java.log_level to 4 and send
the complete log for the above statements.

Please also send the *exact* version of the JVM you
use.

I have tested on two different machines, Solaris with
JRE1.5.0 and Linux with blackdown java 1.4.1. The
above code works on all of them. (I have tested with
php/java bridge 2.0.8, but that shouldn't make a
difference. The coerce code hasn't changed since
version 2.0.7).

Jost,

That would be great, and more so if one could mix directories and single
jar files in the same call!

I'm sure you are right, but still don't understand what I am supposed to
do ... here are a few snippets and their outcome.

1) Let's start with a method invocation where all required parameters
are missing:

   <?php
   $qMgr =3D new Java('com.ibm.mq.MQQueueManager');
   $sdlq =3D $qMgr->accessQueue();
   ?>

   Script output:
  =20
   Fatal error: Uncaught [class java.lang.Exception:
java.lang.Exception:
   Invoke failed: [class com.ibm.mq.MQQueueManager]->accessQueue. Cause:
   java.lang.NoSuchMethodException: accessQueue(). Candidates: [public=20
   synchronized com.ibm.mq.MQQueue com.ibm.mq.MQQueueManager.accessQueue
=20
java.lang.String,int,java.lang.String,java.lang.String,java.lang.String)

   throws com.ibm.mq.MQException, public synchronized com.ibm.mq.MQQueue

   com.ibm.mq.MQQueueManager.accessQueue(java.lang.String,int) throws=20
   com.ibm.mq.MQException]]
   thrown in /opt/phpexe/jbridge/mqt.php on line 3

   /var/log/php-java-bridge.log:

   Java.lang.NoSuchMethodException: accessQueue(). Candidates: [public=20
   synchronized com.ibm.mq.MQQueue com.ibm.mq.MQQueueManager.accessQueue

   throws com.ibm.mq.MQException, public synchronized com.ibm.mq.MQQueue

   com.ibm.mq.MQQueueManager.accessQueue(java.lang.String,int) throws=20

     at php.java.bridge.JavaBridge.run(JavaBridge.java:142)
     at php.java.bridge.ThreadPool$Delegate.run(ThreadPool.java:20)

2) What I think the snippet should look like:

   <?php
   $qMgr =3D new Java('com.ibm.mq.MQQueueManager');
   $mqc =3D new JavaClass('com.ibm.mq.MQC');
   $openOptions =3D $mqc->MQOO_INPUT_AS_Q_DEF | $mqc->MQOO_OUTPUT;
   // gettype($openOptions) returns 'integer' at this point (value:17)
   $sdlq =3D $qMgr->accessQueue('SYSTEM.DEFAULT.LOCAL.QUEUE',
$openOptions);
   ?>

   Script output:
  =20
   Fatal error: Uncaught [class java.lang.Exception:
java.lang.Exception:=20

     at php.java.bridge.JavaBridge.run(JavaBridge.java:142)
     at php.java.bridge.ThreadPool$Delegate.run(ThreadPool.java:20)

3) Let's try with a java.lang.Integer:

   <?php
   $qMgr =3D new Java('com.ibm.mq.MQQueueManager');
   $mqc =3D new JavaClass('com.ibm.mq.MQC');
   $openOptions =3D $mqc->MQOO_INPUT_AS_Q_DEF | $mqc->MQOO_OUTPUT;
   // gettype($openOptions) returns 'integer' at this point (value:17)
   $inte =3D new Java('java.lang.Integer', $openOptions);
   $sdlq =3D $qMgr->accessQueue('SYSTEM.DEFAULT.LOCAL.QUEUE', $inte);
   ?>

   Script output:
  =20
   Fatal error: Uncaught [class java.lang.Exception:
java.lang.Exception:
   Invoke failed: [class com.ibm.mq.MQQueueManager]->accessQueue(class

   thrown in /opt/phpexe/jbridge/mqt.php on line 7

   /var/log/php-java-bridge.log:

In the "candidates" list from the first snippet there is a=20
com.ibm.mq.MQQueueManager.accessQueue(java.lang.String,int)
confirming what one can read from the documentation, where the method is
defined like this:
public synchronized MQQueue accessQueue(String queueName, int
openOptions)
IMHO it really looks like the method is expecting an int for the second
parameter.

If coerce converts the longvals to int, why the error in the second
snippet?
If the method expected a java.lang.Integer instead, why the error in the
last snippet?

Ben,

> Shouldn't java autobox/autounbox Integer to int and vice versa?
> It will if you are using java 1.5 at least.

I have a working PHP script that lists all the Java properties of the
VM, and reports:

...
java.vm.version: 1.5.0_01-b08
...

Massimo

When trying to access a java method with a Boolean param=20
$jcl_sysController   =3D new JavaClass("com.xxx.service.SysController");
$jobj_serviceManager =3D $jcl_sysController->getInstance();
       =20
$jobj_repository     =3D $jobj_serviceManager->getRepository();
$jobj_memberService  =3D $jobj_serviceManager->getMemberService();
           =20
$jobj_repository->begin(false);

I get this exception
