Re: [Php-java-bridge-users] PHP Java Translation Help

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

Hi,

I've used the following code:

<?php
require_once("http://localhost:8080/JavaBridge/java/Java.inc");

$passwd="hello";
try {
  java_require("mail.jar"); // mail.jar is not part of
the standard jdk

  $password=new java("java.lang.String", "$passwd");
 
$algorithm=java("java.security.MessageDigest")->getInstance("md5");
  $algorithm->reset();
  $algorithm->update($password->getBytes());
  $encrypted = $algorithm->digest();
  $out = new java("java.io.ByteArrayOutputStream");

  $encoder =
java("javax.mail.internet.MimeUtility")->encode($out,
"base64");
  $encoder->write($encrypted);
  $encoder->flush();
  echo new
java("java.lang.String",$out->toByteArray()); echo
"\n";
  exit(0);
} catch (Exception $e) {
  echo "Echo invocation failed: $e\n";
  //print_r ($e->getTrace());
  exit(1);
}
?>

The above PHP script returns the encoded "hello"
string.

The java function is a thin wrapper around the
JavaClass constructor. It is defined in Java.inc as:
function java($clazzName) {
 static $cache;
 if($cache) return $cache;
 return $cache=new JavaClass($clazzName);
}

> $md = new Java("java.security.MessageDigest");

Although our plan was to stop development after the
4.0.8 release, I think it makes sense to add another
4.1.1 release which immediately throws an exception
when the above construct is called. At the moment the
bridge only writes a warning message and only if the
log level is >= 3.

The check could be relaxed and turned into a warning
when -Dphp.java.bridge.enable_deprecated=true is set
(for backward compatibility).

The bridge message is correct. There is no static
"update" method in the MessageDigest class. 

I think your Java example uses $algorithm->update(),
not $md->update().
