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

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

Hi there --

Ok, I've been working on this a bit today, reading about how classes
constructs are represented in Java and trying to understand the
documentation itself regarding java.security.MessageDigest and I'm just
not sure why it's not liking the update() call.  Here's the code
evolution so far:

$password =3D new Java("java.lang.String","admin");
$md =3D new Java("java.security.MessageDigest");
$algorithm =3D $md->getInstance("md5");
$reset =3D $algorithm->reset();
$update =3D $md->update($password->getBytes());
$digest =3D $md->digest();


$out =3D new Java("java.io.ByteArrayOutputStream");
$encoder =3D new Java("javax.mail.internet.MimeUtility");
$encoder->encode($out,"base64");
$encoder->write($encrypted);
$encoder->flush();
$the_return =3D new Java("java.lang.String",$out->toByteArray());
echo "output: ".$the_return->trim();

It tosses an exception at the $update call:

javax.servlet.ServletException: PHP Fatal error:  Uncaught
[[o:Exception]:"java.lang.Exception: Invoke failed:
[[c:MessageDigest]]->update([o:array_of_B]). Cause:

Upon printing $password->getBytes() to the screen it simply resolves,
naturally, to admin.  This is correct, I assume, as it's just supposed
to change the series of bytes to the systems character set. =20

So, what is deal?=20
Thanks in advance,
Kate

Hi,

the above PHP code creates a zero-length String and
then calls "".getBytes(<password>). The getBytes()
function needs a symbol as its argument or no argument
at all, not a password. :)


Your Java code translated into PHP is:

<?php
require_once("http://localhost:8080/JavaBridge/java/Java.inc");
$password=3Dnew String("$passwd");
$algorithm=3Djava("java.security.MessageDigest")->getInstance(ENCRYPTION_=
T
YPE);
$algorithm->reset();
$algorithm.update($password->getBytes());
$encrypted =3D  $algorithm->digest();
$out =3D new java("java.io.ByteArrayOutputStream");
$encoder =3D
java("javax.mail.internet.MimeUtility")->encode(out,
ENCODING_TYPE);
$encoder->write(encrypted);
$encoder.flush();
return new String(out.toByteArray());
?>

The PHP Exception objects already provide a suitable

The output from print($e) is much more readable than
the output from print_r($e), which prints the internal

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

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

Vielen Dank, Jost.  This is very helpful :)  This project is my
introduction to Java, so I'm learning how to interpret its default and
imported classes as I go along (and it's the concept of an interface
that is throwing me for a loop at the moment, at least regarding how to
represent this in php).

Question: this doesn't seem to be a php construct to me:
$algorithm.update($password->getBytes());

I will test what you sent to me below and attempt to reconstruct this,
but I thought I'd pose the question here of what this means in php
(specifically the period -- I understand this as a Java (and Javascript
and vbscript, etc) construct rather than the typical -> in php).

Thanks for your help,
Kate

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

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

Hi folks ?

This may be out of scope of the PJB project, but I?m having some =20
trouble translating Java into PHP and this is because I?m rather new =20
at Java (it?s been a trial, to say the least!).

I?m trying to figure out why a string encoding function in Java would =20
return a different value as a seemingly logical reproduction in PHP.  =20
It doesn?t make sense to me so I?m trying to see what the Java =20
function will return via PHP first, but I?m having issues.  If this =20
isn?t too off-topic, please keep reading?

1: a java application takes the string ?admin? and turns it into a =20
hash via md5 and then encodes it via base64 ? and comes up with this:

ISMvKXpXpadDiUoOSoAfww=3D=3D

2: instructions from the developers of this application write ?There =20
are 2 parts to the password, one is the hash, the second is you need =20
to Base64 encode that hash.?

3: I ran the string ?admin? through md5() and then ran that through =20
base64_encode() functions in php.  So base64_encode(md5(?admin)), =20
effectively.  I receive this value: =20
MjEyMzJmMjk3YTU3YTVhNzQzODk0YTBlNGE4MDFmYzM=3D

4: The different return values are confusing me.

5: I have grabbed code provided as an example with their application =20
and it reads like this:

    import java.io.*;
    import java.security.MessageDigest;
    import java.security.NoSuchAlgorithmException;
    import javax.mail.MessagingException;
    import javax.mail.internet.MimeUtility;

    ? other stuff snipped

    private static String encodePassword(String password) {
         MessageDigest algorithm;
         try {
             algorithm =3D MessageDigest.getInstance(ENCRYPTION_TYPE);
             algorithm.reset();
             algorithm.update(password.getBytes());
             byte[] encrypted =3D  algorithm.digest();

             ByteArrayOutputStream out =3D new ByteArrayOutputStream();
             OutputStream encoder =3D MimeUtility.encode(out, ENCODING_TYPE)=
;

             encoder.write(encrypted);
             encoder.flush();
             return new String(out.toByteArray());

         } catch (NoSuchAlgorithmException e) {
             return "Bad Encryption";
         } catch (MessagingException e) {
             return "Bad Encryption";
         } catch (IOException e) {
             return "Bad Encryption";
         }

     }

I translated this as:

$password =3D "admin";
print "encoded: ". encodePassword($password)."<br>";

function encodePassword($password) {
$message =3D new Java('java.security.MessageDigest');
$str =3D new Java('java.lang.String');

        try {
             $algorithm =3D $message->getInstance('md5');
             $reset =3D $algorithm->reset();
             $update =3D $algorithm->update($str->getBytes($password));
             //$update =3D $algorithm->update($password);
             $encrypted =3D  $algorithm->digest();

             $mu =3D new java('javax.mail.internet.MimeUtility');
             $out =3D new Java('java.io.ByteArrayOutputStream');

             $encoder =3D $mu->encode($out, 'base64');

             $encoder->write($encrypted);
             $encoder->flush();

             return $out->toByteArray();

         } catch (Exception $e) {

             print_r($e); // for debugging purposes
             return "<br>Bad Encryption";
         }
}

And I get this in response:

JavaException Object ( [message:protected] =3D> [string:private] =3D> =20
[code:protected] =3D> 0 [file:protected] =3D> =20
/usr/java/tomcat-5.5/webapps/JavaBridge/test_class.php =20

[function] =3D> encodePassword [args] =3D> Array ( [0] =3D> admin ) ) ) ) =
=20
encoded:
Bad Encryption



What I think this is telling me is that on line 25 (which is this: =20
$update =3D $algorithm->update($str->getBytes($password));) something is =20
amiss.  Line 17 is the print out the encoded password line (print =20
"encoded: ". encodePassword($password)."<br>";), which is, obviously, =20
having issues.


*Any* help as I?m trying to learn how to translate Java into PHP would =20
be smashingly appreciated.  And please advise if this is totally out =20
of bounds for this forum.


TIA,
Kate

Hi Jon,

which error message do you get?

The war file contains a 32bit php executable. If your
CPU can execute 32 bit binaries, you can rename the
php-cgi-x86-windows.exe to php-cgi-XXX-windows.exe,
see the error message above.

However, if you have php-cgi.exe installed in the
%PATH%, the bridge will use this php executable
instead of the built-in binary.

The JavaBridge.war contains a log4j.jar library. This
library is responsible for this behaviour. I will
remove log4j from the war file.

[Php-java-bridge-users] PHP/Java Bridge on Windows 2k3 server, 64-bit

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

Hi all,

I'm just wondering if anybody had achieved successful results running
PHP/Java Bridge on Windows 2003 server, 64-bit edition?
I am able to very easily deploy the JavaBridge.war on my own XP (32-bit)
machine, but I get a few startup errors when deploying to a live
environment. Does the *.war also require PHP to be installed on the system
outside of what's provided?

Also, once deploying the package it seems that logging from that point
becomes disabled, e.g. no further server messages are shown - is this a
default behaviour within the app itself?

Cheers,

Jon

Download and install the java.so. On Ubuntu:

dpkg -i php-java-bridge*.deb

Restart tomcat and apache and write a simple test
file:

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

$props = java("java.lang.System")->getProperties();
$array = java_values($props);
print_r($array);

?>

Browse to http://localhost/mytest.php. 

Please see the INSTALL.J2EE document contained in the 
"J2EE" binary download for details.

[Php-java-bridge-users] JPB J2ee installation

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

Hi all
   I've been trying to install JPB to cope with our needs, but i couldn't
find my way in those scattered documents held in PJB site. so, excuse me if
I describe my problem here, so anybody could help me.

   I need to install PJB with the  following specification:use
- targeted OS is ubuntu linux.
- We need to make Tomcat handle JVM in order not to have the JVM loaded and
get-rid-of for every single method call.
- We need that php files be served by Apache not Tomcat.
- We need to use the c impementation not the pure PHP implementation of the
bridge.

Describing installation and configuration steps in details will be
appreciated.
Thanks in advance.
Keep on the good work.

The mingw setup described in the INSTALL document has
been used by our unix->windows cross compiler. Since
the computer doesn't exist anymore, we cannot provide
windows binaries anymore.

The problem is that on Windows i compile everything with MS VS, don't 
have MinGW setup.
 Are you interested in a port to Visual Studio ? This would be 
interesting for a lot of people I guess.
In my spare time i could work on porting...

Hi,

> It is ok now..

if i remember correctly, this gcc optimizer bug is due
to an uninitialized condition variable. Depending on
what malloc() returns, the gcc optimizer creates trash
output. When you compile twice, it is more likely that
malloc() returns a segment which initializes the
variable to zero.

I don't think so. The bind code hasn't been changed

you need to add the java library which exports a
feature needed by MultiThreadedExample$GetThread. Most
likely commons.[1]

Please see the README section "Java platform issues"
or our FAQ for details.

[1] Java's module concept is entirely insane.

Re: [Php-java-bridge-users] failed to install in FreeBSD

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

Hi,

what's wrong with the J2EE download? C compilation
isn't for everyone.

> > Segmentation fault (core dumped)

Which gcc version do you use? Some gcc versions have a
bug in their optimizer. This bug has been reported
twice, against FreeBSD and RedHat Linux. 

The workaround is to switch to another gcc version or
to switch off the optimizer (export CFLAGS="-O0").

In any case, this isn't a problem in the PHP/Java
Bridge code.

You haven't built the back end (the JavaBridge.jar).
If you want to transform java libraries into php pear
classes, you need the JavaBridge.jar.

Which in turn means that you must either install the
required autoconf, automake and libtool versions or
disable back end compilation and use the
JavaBridge.jar from the J2EE back end.

Re: [Php-java-bridge-users] failed to install in FreeBSD

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

It seems not fit FreeBSD

when i use

echo "<?php dl('java.so'); phpinfo() ?>"  | php -n > result.txt
>

it show me:

> Segmentation fault (core dumped)



So i have to rebuild, comand like pre mail.

when finish "sh install.sh" , i find :

Generate PHP classes from standard Java classes and install them in
the /usr/local/share/pear directory?
convert java libraries (yes/no):
Exception in thread "main" java.lang.NoClassDefFoundError:
php/java/bridge/JavaBridge
cp: java/*.php: No such file or directory

"Makefile", line 8: Could not find /usr/share/selinux//include/Makefile
make: fatal errors encountered -- cannot continue
install.sh: /usr/sbin/semodule: not found
install.sh: /usr/bin/chcon: not found
install.sh: /usr/bin/chcon: not found
PHP/Java Bridge installed.

Now type "/usr/local/bin/php test.php" to check the installation.


bridge i today download. Is it ok?

Re: [Php-java-bridge-users] failed to install in FreeBSD

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

Hi,


> Error: The PHP/Java Bridge back-end is not running.

Have you started the back end?  If your php.ini file
dosn't contain any java related entries (which seems
to be the case), the bridge automatically starts a
local back end.  You can find the command in the
result of the phpinfo() command:

echo "<?php dl('java.so'); phpinfo() ?>"  | php -n >
result.txt

cat result.html | fgrep "java command" 

Please take the java command obtained from the
phpinfo() and paste it into a command shell (xterm).

The command should display the reason for the failure,
probably some freebsd java/jdk issue.


In any case, we recommend to use the J2EE binary on
freeBSD, or to use a modern operating system with a
decent TCP socket implementation, for example Windows,
Linux or Solaris.

Jost Boekemeier

Re: [Php-java-bridge-users] How to install PJB in FreeBSD

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

Hi,

the binary/J2EE download contains a binary for
freebsd. Please use this if you cannot compile on
freebsd.

Using the pure PHP implementation on FreeBSD is NOT
recommended because of the well known kernel problem.


The *BSD kernel uses Nagle's algorithm for the local
interface, and the PHP people don't switch it off when
creating/using sockets. Therefore PHP local socket
connections are extremly slow on this operating
system.
-- You can switch off NDELAY for all interfaces using
the freebsd sysctl interface, but doing so is not
recommended.


Hope it helps.

Jost Boekemeier
