[Php-java-bridge-users] passing String[] argument to a constructor

[Guillaume D. <gui...@po...>]

Hello,

we're having problems passing a string array to a constructor. We construct
the array in PHP as follows :

$Array = new JavaClass("java.lang.reflect.Array");
$String = new JavaClass("java.lang.String");
$entries = $Array->newInstance($String, 2);
$entries[0] = 'hello';
$entries[1] = 'world';

and we call the constructor as follows :

try {
	$req = new javaClass('MyApp');
	$req->ProcessFunction($Array);
} catch(JavaException $ex) {
       print "$ex";
}

The error message we get is:

[o(Exception):"java.lang.Exception: Invoke failed:
[c:MyApp]->ProcessFunction2(([Ljava.lang.String;)c:java.lang.reflect.Array).
Cause: java.lang.IllegalArgumentException: argument type mismatch"]

The constructor expects a String[] parameter.

Any clues on how to create a Java String[] from PHP?

I can create Integer, Date, Vector or String objects but arrays ...

I tried:
$String = new JavaClass("java.lang.String[]"); // silly but hey, that's what
debugging is all about :)

Any help would be much appreciated.

Thanks in advance!!

Hi Guillaume,

> $Array = new JavaClass("java.lang.reflect.Array");
> $String = new JavaClass("java.lang.String");
> $entries = $Array->newInstance($String, 2);
[...]
> 	$req->ProcessFunction($Array);
[...]
>...(([Ljava.lang.String;)c:java.lang.reflect.Array)

if I understand this correctly, you want to pass the
created String[] instance to ProcessFunction, not the
$Array class.

Does 

  $req->ProcessFunction($entries)

solve the problem?


BTW: The above error message indicates that the
ProcessFunction2 accepts a [Ljava.Lang.String], i.e. a
String[] but it is called with an argument which is a
class java.lang.reflect.Array.  I agree that this is
difficult to read, but if I make the message more
verbose, php may cut off the rest of the message.

Maybe the full message should go to the PHP/Java
Bridge log.
