Thread: [Php-java-bridge-users] messageDigest and byte manipulation(2)

Hi,


Thanks for you fast answer. 

I try again to implement the Java Array class like that (from the FAQ):

        $Byte = new JavaClass("java.lang.Byte");
        $byte = $Byte->TYPE;
        $Array = new JavaClass("java.lang.reflect.Array");
        $byteArray = $Array->newInstance($byte, 8192);
    
        $n;
        while (($n = $data->read($byteArray)) > 0) {
               $messageDigest->update($byteArray, 0, $n);
            echo "n= " . $n ; 
        }

-> I always got a :   Maximum execution time of 60 seconds exceeded in ...


When I try with a Php int Array like that:

        $buf = array();
        for ($i=0; $i<8192; $i++){
            $buf[$i] = '0';
        }
        $n;
        while (($n = $data->read($buf)) > 0) {
            $messageDigest->update($buf, 0, $n);
            echo "n= " . $n ; 
        }

-> I receive that: n= 184n= 8192n= 8192n= 8192n= 8192n= 8192n= 8192n= 8192n= 8192n= 8192n= 8192n= 8192n= 8192n= 6259 Exception...

Here you can find the original Java code:

        byte buf[] = new byte[8192];
        int n;
        while ((n = data.read(buf)) > 0) {
            messageDigest.update(buf, 0, n);
            System.out.print("n=" + n);
        }


Do you see where the problem can come from?

Best regards Antoine

Well, if you hit the 60seconds, you have no other chance than
1) raise the limit in php.ini
2) optimize your code

what do you want to do with your code? It looks like you are
trying to generate a md5 hash or something like that... php has
build in support for various hashes... also your loop always transfers
data back-and-forth between java and php which makes it slow..
so instead of trying to figure out, whats wrong with the code, it
maybe would be better if you would tell us, what you like to achieve
so we can guide you to a possible better solution.

kind regards,
dominik

Hi,

Yes, this is the correct behaviour. The above statement evaluates to an
endless loop.

$data->read(...) returns a java Integer object. Any object evaluates to
true, according to the PHP type conversion rules.


What you probably want is:

while (($n = java_values($data->read($byteArray))) > 0) {
...

Please see our API documentation at

Thanks Jost,

This solution seem to work.
But I still got a lot of problems for the rest of the script like

[java-code]

        Certificate[] chain = ks.getCertificateChain(alias);
        if (chain.length >= 2) {
            String url = PdfPKCS7.getOCSPURL((X509Certificate)chain[0]);
            if (url != null && url.length() > 0)
                ocsp = new OcspClientBouncyCastle((X509Certificate)chain[0], (X509Certificate)chain[1], url).getEncoded();
        }

How to create an Array of object when you don't know the size...
I can't use :

            $Certificate = new JavaClass("java.security.cert.Certificate");
            $Array = new JavaClass("java.lang.reflect.Array");
            $chain = $Array->newInstance($Certificate, 10);    


Otherwise, do you know someone who can help me to traduce this script (http://itextpdf.sourceforge.net/howtosign.html ->  How to sign with a timestamp and OCSP in Java)

Hi,

[java-code]

       Certificate[] chain = ks.getCertificateChain(alias);
       if (chain.length >= 2) {
           String url = PdfPKCS7.getOCSPURL((
>
> X509Certificate)chain[0]);
>            if (url != null && url.length() > 0)
>                ocsp = new OcspClientBouncyCastle((X509Certificate)chain[0],
> (X509Certificate)chain[1], url).getEncoded();
>        }



=>

$chain = $ks->getCertificateChain($alias);
if (java_values(chain.length)) >= 2) {
  $url = java("...PdfPKCS7")->getOCSPURL($chain[0]);
  if (java_values($url) != null && java_values($url->length()) > 0) {
    $val = new java("...OcspClientBouncyCastle", $chain[0], $chain[1],
$url);
    $ocsp = $val->getEncoded();
 }


Where exactly are the problems?

You can always use

  echo java_inspect($jobject)

to see if a Java method or procedure invocation has returned the correct
result.

However, it isn't possible to blindly convert a Java program to PHP. PHP has
different type conversion rules for example.

If you have a working java library, just add it to your web context and call
it from PHP.

Hi,

I got a error when I call 'getOCSPURL' with the certificate.

$url = java("com.lowagie.text.pdf.PdfPKCS7")->getOCSPURL($chain[0]);

I know $chain[0] contain a valid X509CertificateObject, but I always got that exception: 
#0 C:\Developpement\My Webs\ss_billing\JavaBridge\java\Java.inc(248): java_ThrowExceptionProxyFactory->getProxy(102, 'org.bouncycastl...', '', true)
#1 C:\Developpement\My Webs\ss_billing\JavaBridge\java\Java.inc(388): java_Arg->getResult(true)

#6 C:\Developpement\My Webs\ss_billing\JavaBridge\java\Java.inc(2007): java_AbstractJava->__call('getOCSPURL', Array)

#9 C:\Developpement\My Webs\ss_billing\receive.php(183): billing_pdf::generation(Object(SimpleXMLElement))
#10 {main}

I'm using iText-2.1.7.jar and some other functionality of this library are working fine... any idea ?

Which exception do you get?
