php-java-bridge-users Mailing List for PHP/Java Bridge (Page 98)

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

Why don't you create a string array explicitly, for example by using java.reflect.Array?

The code would look like this:

  $array = java("java.reflect.Array")->newInstance(java("java.lang.String"), $count);

Please see the documentation for details: http://php-java-bridge.sourceforge.net/pjb/extension_mappings.php

I'm stuck and looking for anybody with ideas.  I have a multi-dimensional
PHP array that I want to pass into a Java method that expects a HashMap.  So
far, so good.  I found that I could not pass the array in directly, but I
could pass the php array into a HashMap constructor and then pass that:

// simplified php code to illustrate the problem
$phpArray = array(
    "foo" => "bar", 
    "baz" => array("x", "y", "z")
    );
$hm = new Java("java.util.HashMap", $phpArray);
$myObj->myMethod($hm);

So far, so good.  The problem is that the Java code expects one of the
members of the HashMap to be of type String[]:

// simplified java code to illustrate the problem
// hash is the passed-in HashMap<String, Object>
String[] stringArray;
stringArray = (String[])hash.get("baz");

This fails with a ClassCastException because when the HashMap was created,
the inner array became a HashMap, not an array, and the HashMap cannot be
cast to a String[].  I know if you pass an indexed php array as an argument
to a Java method that expects an array, it will be cast appropriately, but
in this case, the bridge does not have that information available to it, and
apparently defaults to a HashMap for the inner array.

Is there any way that I can make this work without digging into the Java
source?  I've tried multiple methods of "tricking" the bridge into giving me
a Java String[], but it always outsmarts me and makes it a php array().

Michael.

Hi,
 
> I have a question, what is ABI-incompatible headers ?

basically the ABI and its declared API must match. Example: extern void cdecl GetCursor(); will
not work when the ABI expects a different calling convention.

The PHP library carries a tag which is checked when a module is loaded to avoid these problems.

Hi,

> is it possible to get  the FOP converted into php only code?

assuming that the fop library doesn't depend on external libraries and that it can be compiled
into native code (using gcc4), yes, this should be possible. -- Even if gcc is not able to compile
the jar file into a native fop.so library, it should still be able to interpret the jar file using
the byte code interpreter built into libgcj.

Which error message do you get?

Hi,

is it possible to get  the FOP converted into php only code?

In a german magazine is described with
 >java -jar JavaBridge.jar --convert /usr/share/php5/pear fop.jar

I tried it with 0.93 and 0.20 of fop but nothing worked and i always got 
an error.

I want to use FO for generating PDF-files on a webserver without Java VM.

this problem comes up once in a while. And support requests like these =
where the reason why we don't recommend to use the C implementation[1]. =
-- Compiling C code isn't for everyone; the gcc optimizer may be broken =
(gcc 3.3.x), or users may confuse the php.ini used by apache with the =
php.ini used by the PHP-cli, other users install ABI-incompatible =
headers for a system PHP installation, compile against them and wonder =
why the module doesn't load or crash.

Isn't it possible to use the pure PHP implementation instead?

Well, AFAIK there is no php 5.2.3 for Suse Linux available. So I guess =
you have compiled PHP 5.2.3 yourself. Are you sure that you have =
compiled against the 5.2.3 ABI? Or do you have compiled against the ABI =
that came with your Suse Linux operating system?

=20

Do you load the java.so from the php ini file used by apache?

Usually in the back end (in META-INF of JavaBridge.jar) or in the PHP include path.

If you want to allocate a session from the J2EE back end, you need to call java_session(). The
function is exported from Java.inc.

At the moment there is no Java-based PHP interpreter. *IF* we want to make use of
just in time compilation of PHP opcode, we *may* implement a translator. But there are
no immediate plans to write PHP in pure Java, yet.


> 3. I'm missing a basic understanding?

Well, the bridge is just an XML-based network protocol, which translates PHP/Java calls
into XML and then passes them to the back-end.

On modern operating systems this shoudn't be much slower than JSP. However, there are
some older OS, which use Nagle's algorithm even for the local interface. This insane
setting can't be switched off in PHP, so we can't do anything to speed up round-trips
on this OS (BSD).

In both cases it needs a round-trip through the back-end, so I don't know where
the delay comes from.

Not really. In most cases J2EE/FastCGI is as fast (or even faster) than Apache/PHP.

No. -- Well, yes, if you don't have an PHP opcode cache. But this is true for any PHP code.

Unfortunately, I have not been able to code up a simple case (that does =
not
instantiate a class in my several-class library), so the bug report may =
not
be too useful.  I've since re-written some of the code to accommodate a
hybrid method of loading config (some from classpath some from local =
files),
and now it's working again (including the portion that loads from the
classpath).  All of this suggests that it's just a bug in my code.

However, I still added a ticket (#1773240) because the inconsistency =
between
how the code operates when called from a Java app and when called from =
PHP
through the bridge suggests that there may still be a bug there.

Hi ..

I'm (primarily) a Java J2EE developer, working on a project to 
integrate  JAAS security authentication with PHP authentication using 
WebSphere.  Hope to produce a Drupal module if successful; time will tell.

If things go well, one result will be some documentation of the process, 
necessarily limited by my understanding of the JavaBridge and PHP, both 
hopefully growing, and possibly a journal article or two.  I've posted 
preliminaries of the first couple of steps as blog entries at 
http://dorsetwest.com (specifically http://www.dorsetwest.com/node/34).

I'd be grateful for any review by more experienced users of the bridge, 
now and as this moves along so I can catch my errors and misunderstandings.

In the comments that follow I'm using the August 7 build of JavaBridge.

One understanding I'm trying to check relates to the purpose and use of 
the php_java.dll (which I think is what Jost means by the C-based 
extension module ... is this correct?) or alternately the "pure PHP 
PHP/Java Bridge classes" which I can't identify in code.  Have I 
correctly identified the C-based extension?  Where do the pure PHP 
PHP/Java Bridge classes reside, and are they PHP classes or Java Classes?


I find, for example, that on a windows platform with:
* No particular Apache extensions other than enabling PHP 5.2 (installed 
with MySQL and an image package only),

* A JavaBridge servlet running on my WAS server,

* Apache configured to route Java-bound URL's to the servlet engine by 
means of the WebSphere plugin,

That an attempt to access a Java session from a PHP script residing 
entirely in the Apache home directory (invisible to servlet) works quite 
well so long as the critical include directly references the servlet, e.g.

if(!extension_loaded('java')) 
require_once("http://localhost:9080/JavaBridge/java/Java.inc");

Does this mean:

1. Neither the C nor pure PHP extensions are  needed any longer on the 
Apache/PHP side?  I did see an "optional" post by Jost on this list, but 
wasn't sure what the effect of inclusion or non-inclusion at the 
Apache/PHP level had.

I'm aware that the Java side is doing PHP work using its internal PHP 
interpreter

2. The C or PHP extensions are needed, and are included or referenced by 
some mechanism I haven't figured out yet, or

3. I'm missing a basic understanding?

I do note that interpreting PHP through the bridge, e.g. running a PHP 
script that accesses a Java session, using the URI 
JavaBridge/myScript.php is very slow, e.g. 5seconds where JSP is about 1 
second, but that running the same PHP script directly in Apache, even 
though it still references a java session (but only for a single call I 
think) is very fast, less than a second.  I attribute that to the 
improved efficiency of the PHP/Apache collaboration and threading ... 
does that make sense?  Would adding the C or Pure PHP classes affect 
these kinds of performance issues?

Help is welcome ... I've got a few other questions, but will put them in 
another post for clarity.

what do you mean with "cannot run succeed"? Both, the C implementation and the pure PHP
implementation should run well with the zend optimizer. The only thing that the C implementation
does is to take the pure PHP implementation and to compile it to byte code. The optimizer
shouldn't have a problem with that.

Well, AFAIK there is no php 5.2.3 for Suse Linux available. So I guess you have compiled

compiled against the ABI that came with your Suse Linux operating system?

Up to 64M (see the -Xmx JVM option).

Why do you need a tutorial to install the bridge? Your PHP code
should contain a require_once("java/Java.inc") (or "java/Java.php", if you
use version 3.2.1) and your java app must be running. That's all.

I think there's a 3.2.1 version, too.

Yes. Java and PHP don't depend on a particular OS kernel.

Hi,

>  Is a ScriptEngine of
> this type already planned for a future release?

a common approach is to use a ServletContextListener and to store the created context instance 
into the ServletContext of the web application. 

This way we can expose PHP script "beans" to frameworks such as JSF or Spring. 
The only additional argument that the factory needs is the location (the port number) 
of the pool (apache, fcgi, whatever) managing the PHP instances. 

The two new ScriptEngines themselfs will probably be descendants of the php and php-invocable
engine. -- The invocable engine will be tricky, because it needs to suspend execution 
(via "java_closure()") to allow Java calls into the "bean". But this shouldn't be a problem if
allow_url_include is set to On. In the worst case it must use a temporary file.

I think I could implement this for the next version, 4.2.3.

Interesting.  Okay, thanks for your help Jost.  Is a ScriptEngine of
this type already planned for a future release?

Hi,

it releases the PHP continuation immediately. It is taken from the tests,
which check if calling eval with a null works. I will remove that line.

However, you're right that the PHP/Java Bridge should release
the PHP continuation before the ScriptEngine is finalized. At the moment 
it keeps the PHP continuation as long as possible. This isn't a problem in
practice (when ScriptEngines are pooled).

You say that you use the Script API from within servlets. First of all, the PhpScriptEngine
currently always starts a PHP CGI continuation. If you want to use PHP script instances from
a FastCGI or Apache/IIS pool, you currently need a URLReader. I think it makes sense to add
a ScriptEngine which exposes Apache or FastCGI PHP instances through the JSR223 script API.

Thanks Jost!

> then it is better to use a local URL. For example:


Converting HTTP to LOCAL URL did the trick.  It runs a lot faster now, from 16 seconds, it's down to 0-4 seconds.  That's good enough considering that ordinary Wiki pages that do not use PHP-Java Bridge sometimes take up to 3 seconds to load.  



> I assume that is what java_reset() does(?).

Yes. It clears the loader cache, which means that the dynamic loader
must load the classes again and again.

I am just curious... just how much memory does the loader  
cache use up? Can I change its value in some config file?

It was documented in java.c, which doesn't exist anymore. But AFAIK
the documentation contained a warning that java_reset() should never
be used in user scripts.

The next thing I'd like to do is migrate code from 
my test environment (Windows XP) to a production 
environment (Debian Linux).  

Before anything else, I'd like to know if this is the still 
the right place to ask questions on Debian installation or 
is there a more specialized mailing list for this?

I was using 3.1.x J2EE(?) for Windows XP because of the good tutorial
site I mentioned in my last email.  I noticed there is no equivalent
version for Debian.  Instead there is a 4.x J2EE *.DEB file.
This should work just as well, shouldn't it?

Aside from the INSTALL.LINUX readme file inside the archive file
for Debian, where else can I find instructions/tutorials on 
installing on Debian?

Regards,

Filip

Hi Jost!

Actually, the jar files are not in a remote server. 
They are in my PC which I am using as both server and
client.  For some reason, the simple syntax below
would not work:

   java_require("myJarFile1.jar;myJarFile2.jar;...");

That is why I switched to using HTTP urls.  Hmmm...
could it be (another) Java classpath problem?  All the
jar files inside java_require() should be in my Java
classpath right?

I assume that is what java_reset() does(?).  I think I
did this because sometimes my Wiki runs sluggishly
after I visit a page that invokes PHP-Java Bridge. 
That is true, even if the next pages I view do not use
PHP-Java Bridge anymore.  

Hmmm... okay, I'll try your suggestions and hope that
fixes the problem.   I wonder where I got
java_reset()?  Maybe, from an old local copy of some
website?

Filip

Hi Filip,

then it is better to use a local URL. For example:

$here=getcwd();
java_require("$here/jar1.jar;$here/jar2.jar;...");

I don't think so.

No. -- Forget about the java classpath, this is an insane concept.
Please use the jar repository or java_require() instead.


> I assume that is what java_reset() does(?).

Yes. It clears the loader cache, which means that the dynamic loader
must load the classes again and again.

Interesting. Java runs as a separate process. The only common
resource used by both processes is memory. Or this is a placebo
effect.

It was documented in java.c, which doesn't exist anymore. But AFAIK
the documentation contained a warning that java_reset() should never
be used in user scripts.

If you have still performance problems please open a new ticket and 
add a 

  echo java("java.lang.System")->currentTimeMillis();

to the beginning and the end of the script.

I resolved this issue.  It turns out that the problem was caused by my
use of "php-invocable" engine where I should have been using "php".
However, my other questions regarding "(Reader)null" remains.

Thanks in advance for any assistance.
