Everything you install yourself is ignored
intentionally.  Please always install from RPM for two
reasons:

1. RPM keeps the dependencies in a database. If you
manually install software into /usr, the RPM database
content gets out of sync with the file system.

2. RPM's contain SEL contexts. Java, php and the
php/java bridge rely on the correct security contexts.
If you break them, you must switch off SEL entirely or
provide your own contexts and relabel the entire file
system.


However, it is possible to compile your own local
versions of apache/php and the php/java bridge into
/usr/local, please see the INSTALL document (section
"Install from source") for details

Ant: [Php-java-bridge-users] A synchronization problem?

It's a known bug in the thread pool of version 2.0.7. 
Its hould be fixed in 2.0.8, please see the changelog
entry for getNextRunnable from 2005-08-23 for details.

This problem appears only when you have very short
scripts; if one sees this message in a production
environment, I suggest to switch off the thread pool
or to upgrade to 2.0.8.

[Php-java-bridge-users] A synchronization problem?

[SQUILLACE M. <msq...@so...>]

Hi Jost,
=20
Having at last connected a PHP script to WebSphere MQ via the
php-java-bridge I've been benchmarking the connection with Apache "ab",
and while the results are good performance-wise, the following error is
intermittently logged:
=20
Exception in thread "JavaBridge" java.util.NoSuchElementException
        at java.util.LinkedList.remove(LinkedList.java:644)
        at java.util.LinkedList.removeFirst(LinkedList.java:134)
        at
php.java.bridge.ThreadPool.getNextRunnable(ThreadPool.java:33)
        at php.java.bridge.ThreadPool.access$100(ThreadPool.java:7)
        at php.java.bridge.ThreadPool$Delegate.run(ThreadPool.java:20)

The error occurs only when I specify a concurrency level greater than 1
- in my current setup it is most evident when running 5 concurrent
clients, which is not that much load.
=20
From what I gather there may be a problem with thread synchronization in
the bridge; what do you think?
I'm still running php-java-bridge v.2.0.7 and plan to upgrade, but can't
see anything in the changelog that addresses a similar problem.
=20
On a side note, I observe decreasing throughput after running several
benchmarks with identical parameters: the slugginess goes away when I
restart the bridge ... do I need to explicitly invoke some "garbage
collection" method at script's end?
=20
Bye,
Massimo

[Php-java-bridge-users] PHP install issue

[I l <is...@ho...>]

I've had to manualy install php 5.0.4. The php binary is located in 
/usr/local/php5/bin

Running the RPM for FC, I get these two dependencies errors.
/usr/bin/php is needed by php-java-bridge
php >= 5.0.4 is needed by php-java-bridge

It looks like its searching for php in the wrong directory. I've tried using 
links to those binary php files. But it still gave me the same error. I even 
copied the binaries to that directory. It seems like I will need to install 
php to the default directory, but unfortunetly I cann't.


Is there anyway to tell the rpm to look for the php in the right directory? 
Or another way around this. A buddy of mine said install another version of 
php.


I've looked everywhere on your site and tried searching your mailing lists 
with no success.

Your help would be greatly appreciated.

Thanks.

So if you wanted an Integer, couldn't you just do

$i = new java.lang.Integer(3);
$hash->put($i);

Or doesn't that work?

if  you use the standalone backend all your caches and
all your session vars are gone.

When the backend (JavaBridge.war) is running in a j2ee
server, java_reset() does nothing. 

(j2ee servers have their own methods admin
interfaces).

[Edward H. <edw...@ya...>]

Hi Jost,
 
Thanks for the advice. I managed to find and fix the bug this morning which pertains to a static variable not being set correctly as you predicted.
 
Just out of curiousity, what is the harm of using java_reset() unnecessarily (i.e. in the event that no libraries or setup files have been changed). 
 
This is so I can bear this in mind in the future if I happen to encounter a similar problem.
 
Thanks very much for your assistance.

java_reset() is a privileged procedure and should only
be used by admins (after the setup or the libraries
have changed for example).

If possible set the log.level to 4 and check why the
second call fails. If you can't find the problem
yourself please create a bug report, please see

how should this work when the parameter doesn't have
any type information?

$hash->put(3);

should the 3 be converted into an Integer or a Long?

Currently it's a Long (for ext/java compatibility).

the class is garbage collected when your VM has a
class GC and this GC is called. In the standard
configuration (64MB heap) the
tests.php4/binaryData.php test triggers such a GC.

This caching behaviour is intentional.


Everything else (instance variables etc.) is destroyed
after script execution.

It is certainly possible to write a counter using a
static variable so that a method call fails after some
time. But I don't think this is a good programming
practice. :)

Can you please be more specific? If possible please
set the java.log_level=4, create a bug report and
attach the log up to the point where the problem
occurs. (please see

RE: Ant: RE: Ant: [Php-java-bridge-users] Problem compiling version 2.0.7 on Red

[Jim D. <jd...@ho...>]

Jost,
  Thanks for compiling for RH 9.0, that solves that problem.  I have a 
problem with PHP seeing the java.so.  When I run a test with, echo '<php 
phpinfo() ?>' | php | fgrep java, I get the folllowing error;

PHP Warning:  Unknown(): Unable to load dynamic library './java.so' - 
./java.so: cannot open shared object file: No such file or directory in 
Unknown on line 0

(I tried the full path also in the php.ini, 
"extension=/usr/local/lib/php/ext/java.so")

What I have done,
1- Tested  and confirmed that I have PHP 4.4.0.  It is running fine and 
serving up web pages.
2- I copied the java.so to the PHP install directory, /usr/local/lib/php/ext
3. I added "extension=java.so" to the php.ini
4 - I copied JavaBridge.jar /usr/opt/tomcat/webapps/WEB_INF/lib
(Is this the correct directory to copy to JavaBridge.jar to?)


Thanks, for the compiled code, and I really appreciate your help!

Jim

[Php-java-bridge-users] How instances are handled in java bridge

[Edward H. <edw...@ya...>]

Hi,  
I'm also wondering how instances are created and destroyed using java bridge. It seems to me (and from reading the docs) that when instances are created i.e. when u do smth like 
$newinstance=new java_class("java.lang.someclass"); 
This class and all variables/properties belonging to that class will never get destroyed? Is this correct? 
 
This is because I have a class and when I run JavaBridge.jar and execute the class for the first time it always works. But subsequent calls to that class will fail unless I shut down JavaBridge.jar (by terminating javaw.exe from Task Manager) and restart it again. And it also works when I call the java class from command prompt and calling it multiple times does not create any problem.
 
The error that I'm getting is ArrayIndexOutofBounds Exception on one of the variables of the class. I'm just wondering if there is any difference calling java class from command prompt and calling it via the java bridge which can explain this behaviour.
 
Thanks.

That's what I was trying to get at - if int<->Integer conversion works,
then it is easy to instantiate an Integer from PHP code and pass that to
your Java method. There would be no need for the "php ints are java
longs" flag.

R: R: R: R: [Php-java-bridge-users] Primitive types [SOLVED!]

[SQUILLACE M. <msq...@so...>]

Jost,

Success!

Before calling the snippets I sent you it was necessary to setup
WebSphere MQ environment, but since the statements I used didn't signal
any problems I was confident it was all OK; moreover I got the same
errors as those I sent you with or without such initialization.

Now, to prepare the environment you have to set specific key/value pairs
defining the server to connect, the port and the channel to use, and
following the manual e.g. I assigned the value 'MY_TEST_CHANNEL' to a
key 'CHANNEL_PROPERTY'.

What I didn't understand was that I had to instantiate a class named MQC
and susbstitute the key name with something like $mqc->CHANNEL_PROPERTY
(which points internally to a string valued "channel").

As soon as I realized this and made corrections the scripts ran fine
through the end, writing a message a reading it back (and quickly too!).

The exceptions reported put me on the wrong path, and I don't know why
they were raised ... it appears there is nothing wrong with type
coercion in the bridge.

Thank you very much for your help,

Massimo

I think it is a mistake to rely on auto-conversions,
especially if the function parameter doesn't have any
type information (e.g. the type is java.lang.Object).

Under some circumstances PHP changes the number type
from exact to inexact. If your hash table contains a
Long with the value 1 and you ask for $i (when $i is a
float), this will not work either.

Depending on whether the proposed "php ints are java
longs" flag is set or not, you will ask for a
java.lang.Long object with the value 1 or for a
java.lang.Integer object with the value 1.

Hi,

Well, people have a reason why they use php 4.3.2,
4.3.3 or 4.4.0 or 5.0.x.  Certain extensions only work
in one of these versions.

So if users what to use a specific version of php for
which no binary exists, I usually ask them to compile
from source.

> I've tried to

Which errors specifically?

I didn't think this is possible. PHP is missing
features which are essential for desktop applications.
For example it doesn't have threads; it relies on the
web server to provide an "execution environment".

There are other environments which support the PHP
programming language for example a php -> CIL compiler
exists for the MONO project. 


> Yes, sometimes. 

Okay.  I think it is possible to split the zip file
into a "documentation" zip and a zip file which
contains the php_java.dll, the php.ini and a short
readme.

I don't see how this could be automated.  Some people
use IIS, others prefer apache.

Sorry, the parameters are documented in the
INSTALL.WINDOWS document only.  The README is indeed a
little bit unix centric; unix users usually start the
bridge via the php-java-bridge.service script or via
the php-java-bridge command.

If you install with "rpm -i php-java-bridge*.rpm" or
by double-clicking on the .rpm, the RPM package
manager will automatically set this up.

AFAIK windows doesn't have such a setup program. But I
am not a windows expert, though.
 

> I don't think it is easy, esp. for me. =) 

What I meant was: Isn't it possible to use
java_closure() for this?  For example:

<?
class test {
  function toString() {
    $sys=new JavaClass("java.lang.System");
    return "Hello java from php@" . $sys;
  }
}

$t = new test();
$javaT = java_closure($t);
echo $javaT;
?>

=> [proxy0: "Hello java from php@100982"]


The problem is that Sun's dynamic proxy doen't accept
a super class, i.e. the parent class is always
java.lang.Object.  There are several open source
implementations which change this.

But in practice I think this isn't an issue. You can
always delegate, e.g. use the decorator pattern.

In order to set java.log_level to 4 I had to restart the php-java-bridge
(I also restarted Apache just in case) and, as you can see from the
above, now the exception is slightly different ("object is not an
instance of declaring class" instead of "java.lang.ClassCastException");
could be because of my previous tests, sure, but makes me think ... if
script 1 modifies the global environment of the bridge scripts 2 and
following are all influenced ... what if script 1 is buggy?

Re: [Php-java-bridge-users] HashMap->get()

[Nicolas G. <nic...@gm...>]

Yes, you're right. I've reviewing all the code again.the difference was
this:

In the first code I do this:

$i=3Dnew java("java.lang.Integer",1);
$i=3D1;
$Cliente=3D$h->get($i);
echo "Cliente:".$Cliente->toString();

see that line in red, I didn't post it in the previous mail :(

now I understand why didn't work. When I do "$i=3D1" I make the $i a long. =
So,
the only way that we can handle Integer is with the java constructor.

RE: [Php-java-bridge-users] exception when using a method that takes a boolean

[Bharath T. <bh...@mv...>]

Hi Jost

Yes, HibRepository.java is my class. Let me double check on the config
properties

Hi,

this sounds as if some config properties are missing.

Is HibRepository.java one of your classes?

Shouldn't java autobox/autounbox Integer to int and vice versa? It will
if you are using java 1.5 at least.
