[Php-java-bridge-users] IllegalArgumentException when passing correct object

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

Hello,

I'm working on a project that needs pdfbox. I need to call a method which
expects a subclass from abstract-class ProtectionPolicy. If i pass this
object i get an IllegalArgumentException:
Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: Invoke failed:
[[o:PDDocument]]->protect((o:ProtectionPolicy)[o:StandardProtectionPolicy]).
Cause: java.lang.IllegalArgumentException

Documentation:
http://www.pdfbox.org/javadoc/org/pdfbox/pdmodel/encryption/StandardProtectionPolicy.html

I believe i'm using it the right way. Anyone got an idea what i'm doing
wrong?
My code:
$ap = new Java("org.pdfbox.pdmodel.encryption.AccessPermission");
$ap->setCanModify(false);
$oDoc = new Java("org.pdfbox.pdmodel.PDDocument");
$oProtect = new Java("org.pdfbox.pdmodel.encryption.StandardProtectionPolicy
","test","test",$ap);
$doc = $oDoc->load( "/home/www/testserver/webapp/upload/test.pdf");
$doc->protect($oProtect);
$doc->save("/home/www/testserver/webapp/htdocs/testcases/out/testoutput.pdf");

Thanks in advance,

Gilbert

Hi,

you're right that the error message is confusing. You will get more information if you
raise the log level.


> [[o:PDDocument]]->protect((o:ProtectionPolicy)[o:StandardProtectionPolicy]).
> Cause: java.lang.IllegalArgumentException

In one of the next versions we will include the classloader in the output, so that the 
error message will read:

  [[o:PDDocument]]->protect((o:ProtectionPolicy@CL1)[o:StandardProtectionPolicy@CL2])

The problem is that StandardProtectionPolicy is assignment-incompatible to ProtectionPolicy. 
Please re-read the "java platform issues" and the "class loading" section from the readme and 
change the java_require() call so that it includes all interconnected libraries.

P.S.: The code I've tested is:

<?php require_once("http://127.0.0.1:8080/JavaBridge/java/Java.inc");
$here=realpath(dirname($_SERVER["SCRIPT_FILENAME"]));
if(!$here) $here=getcwd();
java_require("$here/PDFBox-0.7.3.jar;$here/bcprov-jdk15-137.jar;$here/bcmail-jdk15-137.jar");

$ap = new Java("org.pdfbox.pdmodel.encryption.AccessPermission");
$ap->setCanModify(false);
$oDoc = new Java("org.pdfbox.pdmodel.PDDocument");
$oProtect = new Java("org.pdfbox.pdmodel.encryption.StandardProtectionPolicy","test","test",$ap);
$doc = $oDoc->load( "$here/test.pdf");
$doc->protect($oProtect);
?>

Hi again,

the log of the back end already contains enough information.
When running in a J2EE server, this problem won't appear. And including the instance# of
the dynamic class loader to the output will be more confusing than what we have now.

Thus I will not change anything.


These class loader related issues are common Java problems. And it is not the PHP/Java Bridge's
job to workaround these Java platform specific problems.
