php-java-bridge-users Mailing List for PHP/Java Bridge (Page 3)

Hi Andrè,

most of the *.java files are licensed under the MIT
license, except javax/script/* and 3 files in
php/java/bridge.

Sanka's open-source javax.script implementation is
licensed under the Apache License (unspecified
version).

Base64EncodingOutputBuffer.java was taken from the
Apache "Geronimo" application server, licensed under
Apache Software License 2.

CGIServlet.java was written by Martin Dengler and is
licensed under the Apache Software License
(unspecified version).

DynamicClassLoader.java was written by Kai Londenberg
and is licensed under the PHP license, which is
similar in spirit to the Apache Software License.


> php-java-bridge/examples/php+jsp/numberguess.jsp   

This file is obsolete.

> Base64EncodingOutputBuffer.java ASL 2.0

There are certainly other implementations. I think the
classpath project contains one licensed under the
lesser GPL. But I prefer to keep the *.java files
under the MIT or Apache license.

> CGIServlet.java ASL 1.1

We could ask Martin if he is willing to distribute it
under a different license.

I don't see how the lesser GPL is incompatible to the
Apache or PHP license. 


> Could they be moved to GPL?

The Base64 encoder could be replaced. But I don't know
if the other authors are willing to distribute their
code under a different license.

Hello,
I found at http://www.ohloh.net/projects/4800  (interesting page for
php-java-bridge) that php-java-bridge has 3 files using Apache License.
Searched the sources and found:
php-java-bridge/examples/php+jsp/numberguess.jsp    ASL 2.0
php-java-bridge/server/php/java/bridge/Base64EncodingOutputBuffer.java
ASL 2.0
php-java-bridge/server/php/java/servlet/CGIServlet.java ASL 1.1

As noted at
http://www.ohloh.net/projects/4800/factoids/122875
ASL and GPL are incompatible.
http://www.apache.org/licenses/GPL-compatibility.html
http://www.gnu.org/philosophy/license-list.html

Maybe some long forgotten files in the tree, but the issue should be
clarified.
Please, will these files continue to be licensed under ASL?
Could they be moved to GPL?

Hi,
  What is a proper way to set (incoporate) my application
log4j.properties file in java bridge?  As I know log4j properties are
set just once; since it was set by java bridge, it ignored my own
log4.properties. =20

Could I use eclipse to debug my code and inspect the values at the point
where the bridge invoking a method in my app? Currently, my backend is a
standalone app.

Thanks for your time

Gee (blush) - how embarrassing: I had been looking at this code snippet at
least a hundred times now and in the end it turned out, that my condition
actually read

      if (!$var) { ...

instead of:

      if ($var) { ...

Somehow my eyes and brain always ignored to see that '!' between the '('
and the '$'

It's all up and settled now! Sorry for the bandwidth abused,
Michael

Ooops - sorry - my error: you had asked for the PHP version not the
PHP/Java-bridge version: I am using PHP 5.1.6.

--> <C v="demo.NCI" p="I" i="6be6668" />
--> </C>
<-- <O v="1" p="O" i="6be6668"/>
--> <I v="0" m="castToBoolean" p="I" i="63bf1c4" />

According to the protocol you use the following code:

$obj = (boolean) new java("demo.NCI");

The result of the cast is true.

<-- <B v="T" i="63bf1c4"/>


At least on protocol level there's nothing wrong with
your code; you've casted the result object to a PHP
boolean value.

I don't know where the boolean cast comes from and why
you or the PHP interpreter confuses the PHP boolean
value with a PHP null object.

Which PHP version do you use? And how exactly does the
code look like?  Note that PHP sometimes uses implicit
casts, depending on the context, for example "$obj"
implicitly casts $obj to a PHP string value.

Are you sure? IMHO the PHP/Java Bridge only supports
PHP 4.3.2 and above. 

Or do you use some other PHP implementation?

-------------------------------------------------

The "NCI-ctor()" line (about 20th from bottom) comes from the constructor,
which reads:
      ...
      public NCI() {
            System.out.println("NCI-ctor()");
      }
      ...
and since it's the only thing the constructor does, I would assume that it
also completes.

That means, it is the returning of the object that must fail, or how could
I otherwise get a null back from the constructor?

But the line
...
Result [Object 2059172540 - Class:
demo.NCI:ID1344884777:LOADER-ID1560567044]
...
(seventh line from the bottom) suggests that there actually IS some object
returned, so why does the PHP-code then obtain a null???

Really puzzled!

OK - and what exactly does that now tell us???

Michael  (puzzled...)

Sorry, but that instruction was to terse for me. How/where exactly do I set
that protocol level so that I can monitor what is going on?

I am running the PHP/Java bridge 1.3.8 on XAMPP v1.5.4a on a Windows XP box
and I enabled the PHP/Java bridge by placing the files
"WEB-INF\lib\JavaBridge.jar" and "WEB-INF\cgi\java-x86-windows.dll"
(extracted from the file "JavaBridge.war") into C:\Program
Files\xampp\php\ext (the latter under the name "php_java.dll" and adding a
line "extension=php_java.dll" to php.ini). That's at least how I learned to
install and enable the php/java bridge...

Hi,

you're right that new Java(...) cannot return NULL.

> How can I figure out, what's going wrong here and
> why???

You can look at the protocol level. Either set the log
level to 4 or above or, if you use linux, type:

strace -s 1024 php yourPhpScript.php >error.log

You will see something like:

--> <C p=3D... v=3D...>...</C>
<-- <O v=3D.../>


Which PHP version do you use, btw?

Yes, generics (implemented as erasures) are no problem
for the bridge. Please see our FAQ for details. Real
generics, as proposed by the Rice people (which could
be the base of a proper java module system) need some
adjustment within the bridge code.


> Does the bridge

You probably mean "does the bridge support java
generics"? Yes, it does. 

Does it support a generic syntax? No. Java only
supports generics on its surface, the byte code below
is still the same as in java 1.4.

Implementing a syntax transformer (something like
Scheme's define-syntax) for PHP is outside the scope
of the PHP/Java Bridge. 


> Could the syntax be like?
> new java("java.util.List<String>");

The syntax is:

  new java("java.util.List");

Hi
  For my application, most of the methods use generic as a parameter or
return value (e.g. List<Foo>).  Does the bridge support generic systax.
If it does, could I have a link to the document?

Could the syntax be like?
new java("java.util.List<String>");

Hi,


Please open a ticket, please use 

http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233

and attach the log of the bridge there.


We'll check this issue asap.

Depending on whether you use the Apache front-end or
the J2EE back-end directly, a) you need to install the
java.so/php_java.dll or b) set the path to the php
executable, respectively.

That is: 

http://localhost:8080/JavaBridge/test.php
invokes the php_exec from the web.xml, 

http://localhost:80/JavaBridge/test.php invokes Apache
or IIS and triggers the php.so or php.dll which in
turn reads the php.ini which in turn loads the java.so
or php_java.dll.

Well, as someone else noted, your only mistake was
that you thought that getInstance evaluates for its
side effects. But this isn't the case. It is a
function.

Okay.

Okay. This means that even if the machine boots,
tomcat  (and the bridge) will re-start automatically.
Good.

Your ISP doesn't want you to start java from the
console. This is usually a GRSecurity or SEL issue.

Not really. You can restrict Java so that it core
dumps on startup. Please take a look at the SEL files
distributed with the php-java-bridge source download.
Sun JDK 1.5 for example creates executable files in
the temp dir with global permissions. This is very
insecure, imho. If you switch off these permissions
via a SEL rule, Java will crash in the garbage
collector or in the JIT thread.

It all depends on the SEL context. Presumably tomcat
runs in the initd_t context, not in unconfined_t. But
that's guesswork.

I am using php/java bridge 3.1.8. I am having the interesting case that in
my PHP code I do a

      $classpath='...';
      java_require($classpath);
      try {
            $var=new Java('class.name.here');  // the constructor has no
paramete
      } catch(JavaException $exeption) {
            throw new Exception('Java-exception creating object of class
"class.name.here": '.$exeption);
      }
      if ($var) {
            // using the object...
      } else {
            echo 'got a null object... :-( ';
      }

Initially I was getting misc. ClassNotFound-Exceptions until I got my
classpath right. The classpath seems to be OK now, but now I am NOT getting
any JavaException but I get back a null-object, i.e. I am falling into the
echo ... statement in the above snippet.

How can I figure out, what's going wrong here and why???

Michael

I appreciate your attempt to help with this, but the documentation and
my lack of Java knowledge is becoming tedious.

I get this message when running the script that you and I have been
sending back and forth:
---------------------
PHP 5.0.4 too old.
For PHP versions < 5.1.4 install the java.so or php_java.dll from the
php-java-bridge-legacy download.
Or set the path to the PHP executable, see php_exec in the
WEB-INF/web.xml
---------------------

The web.xml file lists this php_exec under a section titled "PHP CGI
servlet: when IIS or Apache are not available" and I have put the php
binary as a value (uncommented). =20

What I don't get is that Apache *is* available, so why is the
documentation steering me towards this implementation?  Please explain.

I do not understand how PHP deals with Java's instances.  I do
understand objects and classes from a PHP perspective, but I have just
begun to learn Java so this process has a learning curve for me.  Try to
be open-minded.

I installed this: php-java-bridge-4.0.7_j2ee and though the environment
is a virtual dedicated server, my rights are sadly limited.  If I could
update php I would.

I've got tomcat running on autostart and have the bridge in its webapps
directory. =20

If tomcat is supplying the VM, why am I getting stack heap issues in
trying to start a VM when merely calling java -jar JavaBridge.jar --help
?

This has *got* to work, I just need to figure out how...

--K

  $algorithm = java("java.security.MessageDigest");
  $algorithm->getInstance("md5");
  $algorithm->reset();
 
  As far as I understood the discussion this should be $algo = java(...)->getInstance(...).
  You want to reset the algorithm, not the class, no?
   
  8=)

Hi,

> And a beginner with Java I am, indeed.  

Isn't it possible to test your scripts on a local
computer? 

When they work, you can create a web archive (.war
file) and deploy it into the Tomcat/J2EE server of
your ISP.

After that symlink or copy the scripts from the tomcat
webapps directory to the Apache or IIS document root
and you're done.

Hi,

which version of the bridge do you use?

> same exception as a few days ago, which was that
> update() didn't exist:

Yes, I've seen the message. However, the message was
correct, update is not a static feature of the class.

> In other various tests it would toss a "reset()
> doesn't exist"

How does the code look like? Do you see the reset()
function when you call 

  echo java_inspect($obj);

I think you've confused the class and the instance.

What do you mean with this? The init-param is still
commented out!?!

This is a misunderstanding, anyway. The J2EE component
uses the built-in php-cgi.exe, which is 5.1.4. But you
want to use Apache or IIS as a front end and the PHP
version installed there.

I didn't know that you use an old version of PHP,
sorry.

> When I run 'which php' I get '/usr/bin/php'

Irrelevant. The Apache binary uses a dll/shared
object.

Too bad.
