[Php-java-bridge-users] session sharing with JavaBridge

[Raphael V. <rv_...@os...>]

Hi,

I installed php-java-bridge_2.0.8RC2 on Apache Tomcat/5.5.9 on Windows and use it from PHP  5.0.4 on the same machine.
While testing the examples I noticed some strange behavior.

Scenario:

JSP Url: http://localhost:8080/JavaBridge/sessionSharing.jsp

PHP Url: http://localhost/JavaBridge/sessionSharing.php


If the first hit goes to the PHP-Page it creates a cookie with the following information:

name: JSESSIONID
value: 84C9FD1F9C6AF4D81AAC24F6395DE10F
host: localhost
path: /

If the next hit goes to the JSP it recognizes the cookie and use the same session as expected.


If the first hit goes to the JSP it creates a cookie with a different path:

name: JSESSIONID
value: B9B7C792CB0242E808789B4DD7CD7A3A
host: localhost
path: /JavaBridge

Now the PHP-Page don't use this cookie and create an new one with path = / and the session will not be shared.

Is this a bug in JavaBridge or it is standard behavior of Tomcat? Is there any way to change it?

regards,
Raphael

Cool. I'll get MediaWiki set up - cycles are a bit short right now, but
I should have something next week. Any suggestions on a domain name?

Is there anything in particular folks would like to see besides the
documentation? I think it'd be nice to have a FAQ and a How-To section
with some nice sample code (adding Lucene searches to PHP apps is
especially cool).

Yes, I think that's the easiest solution.  I will add
a setting to the web.xml and document that this
setting is used when java cannot read the SystemRoot
environment variable or when the SystemRoot
environment variable is not set.=20

That way users can change it the way they want.

I will also add a System.properties option, syntax:=20

  java -DWindows.SystemDir=3D...

which overrides everything else, including the setting
from the web.xml.  That way your setup program (if you
provide one) can start tomcat with the correct
SystemDir setting and then write out the correct
web.xml for the user.

Hi Bharath,

which JDK and Windows OS version do you use? I do not
understand why some versions of windows require the
SystemDir environment variable. There's no reliable
way to read or set environment variables from java.=20

I have just tested on several systems, including XP
home and win98, none of these need SystemDir.  The
only system that I know of is XP, but this problem
goes away when I install network programs. =20

Maybe it is necessary to set a registry entry which
points to the correct SystemDir.  I will check this.


> Variable was pointing to C:/Windows (the correct

In JDK1.4 it is hard-coded. The code which does this
(in CGIServlet) looks like this:

try {
  var=3DSystem.getenv("SystemDir");
} catch (Throwable t){}
if(var=3D=3Dnull) var=3D"c:/winnt";

The problem is that Sun has introduced getenv() in JDK
1.2, then deprecated it in 1.4 and then un-deprecated
it in 1.5 and now recommends this to pass the
environment to the sub-process.

In other words there is no reliable way to ask for the
value of SystemDir in java.

I think it is possible to read the registry from
jdk1.4.  But this will not work either if the registry
key (which one?) is missing.

I have re-opened the ticked.


As a workaround please use Apache/Php/PhpJavaBridge
and Tomcat/mod_jk connector. This is described in the
INSTALL instructions and in the README.  This is also
much faster than calling CGI programs or native code
from java.

Jost Boekemeier

I have tried the latest build (php-java-bridge_2.0.8RC1.zip) and still
running into the same problem

Fatal error: php_mod_java(52) system error code: 10106. Could not

I had cleaned up all my old installations restarted the machine and then
reinstalled it so there is noway that there was a remnant of the old
installation.

Now when I ran test.bat things were fine and could see the java system
properties printed out but when I tried to browse the test.php through
tomcat I ran into the same problem. On a closer look=20
I found that in the case of phpinfo output through test.bat the

It was pointing to C:/Winnt (a non existent folder on the machine). Are
we
hardcoding this path?

[Jost B. <jos...@ya...>]

Hi Jonathan,

Thank you very much for the bug report.  The non-j2ee
Session (please see
http://cvs.sourceforge.net/viewcvs.py/php-java-bridge/php-java-bridge/server/php/java/bridge/Session.java?rev=1.10&view=markup)
is currently backed by a Hashtable.  That must be a
HashMap, of course[1].

If you have the JavaBridge backend running in eclipse,
please change the line

    protected Hashtable map;

to

    protected HashMap map;

I will fix this bug for the official 2.0.8 release.

Please use $session->remove($var).  Please see
http://cvs.sourceforge.net/viewcvs.py/php-java-bridge/php-java-bridge/server/php/java/bridge/ISession.java?view=markup


> With that in mind, a full explanation of how to use

The java_get_session() invokes JavaBridge.getSession()
which returns an ISession (see above).

The actual implementation is either the servlet's
HttpSessionFacade or our own Session.java, when the
backend runs outside of a standard j2ee environment.

Please see the interface ISession.java above.

That would be great. If you want to document the 10
ISession methods, we can give you CVS write account.

That's also a good idea.  But then we need someone to

do the synchronization ourselfs.  I guess that was the

If you look at the code in server/php/java/bridge/Session.java, you'll
see that put() expects two objects, so putting "null" will always throw
that exception.

$session->remove("key") will remove a variable.

I'd be happy to contribute to a documentation wiki. I even have some
server space to set one up, if need be. The bridge works great, but
documentation is definitely on the "Use the source, Luke" side :)

I just wanted to say thanks for a great piece of software. Being able to

Hi,

I have fixed this problem.  It turned out that the
windsock.dll was not found because the SystemRoot"
environment variable was not defined. (I don't
understand why windows needs this, isn't SystemRoot
always c:/winnt or c:/windows?)

I will prepare version 2.0.8pre1 tomorrow which fixes

Can you give an example, or better yet a test case which shows the

Which version of the php java bridge do you use ? If it's not the
latest version, try to update and then check if the problem still
occurs.

Also, If you can't create a test case outside of your development
environment or don't have time for that - try to find out where the
problem occurs - if the Java code gets called at all, if an exception
occurs.

Put the log level of the php-java bridge to 4 or higher and then look
at the log whether any problem is reported.

the default value is (or should be) 1400 seconds.  It
can be changed with:

$session=java_get_session(..)
$session->setTimeout(timeout_in_seconds);


How fast does the session expire? We've had a bug in

Ant: [Php-java-bridge-users] NoSuchMethodException: __sleep()

[Jost B. <jos...@ya...>]

Hi Jonathan,

> php_mod_java(59): Synchronization problem, rinit
> with active connection called.

thank you very much for this problem report. Now
suddenly PR1202896 ("session still open in rinit")
makes sense.

The basic problem is the same that Bryan has reported,
please see:

http://sourceforge.net/mailarchive/forum.php?thread_id=7884155&forum_id=42415)

Kai has already explained what what __sleep() means
and how to store java objects.

During client/server communication both the client and
the server build a dictionary of (handle . object)
pairs. When you serialize/deserialize a handle without
restoring its server-side meaning the server and
client suddenly use different dictionaries and very
strange things may happen; it is like switching the
language in the middle of a conversiation. In a
sentence like "hier is gift", the server should better
know that "gift" means "poison", otherwise it will get
into trouble when the client asks to handle() it.

Please use $session=java_get_session(<name>) to store
java values.


Okay, now how to handle the problem?  We could
implement the __sleep() and __wakeup() methods and
abort script execution if they are called. But I think
it shouldn't be too diffcult to implement them
correctly: All we need is to move the pair from the
globalRef into the session ref when _sleep() is
called. __wakeup() is a little bit more complicated
because we restore an object which has the old
(client-side view) of the object identity and we
receive an object from the session ref which has the
correct identity.  We must "patch" the restored object
to contain the correct id and then discard the
received object.

I have created a ticket for this: PR1274526.

In the meantime please use java_get_session() to store
your java values.


Regards,
Jost Boekemeier

[26-Aug-2005 08:52:27] PHP Notice:  php_mod_java(57): waiting for server =
another 14 seconds in Unknown on line 0

In my Apache error log, after I visit a page:
=20
[client 10.1.150.118] PHP Fatal error:  Exception thrown without a stack =
frame in Unknown on line 0
[client 10.1.150.118] PHP Fatal error:  php_mod_java(59): =

I'm seeing this in my php-java-bridge.log file:
=20
java.lang.NoSuchMethodException: __sleep(). Candidates: []
        at php.java.bridge.JavaBridge.Invoke(JavaBridge.java:966)
        at php.java.bridge.Request.handleRequests(Request.java:190)
        at php.java.bridge.JavaBridge.run(JavaBridge.java:142)
        at php.java.bridge.ThreadPool$Delegate.run(ThreadPool.java:20)

It looks like the php-java-bridge log error happens the first time I run =
a particular page, then the "exception thrown without a stack frame," =
etc. occurs when I try to rerun the page.  At this point, my PHP pages =
will stop responding until I restart Apache.

The code snippet that's (probably) causing the problem:
=20
 GLOBAL $doctypes;
=20
 try
 {
  $pac =3D getPingActionClient();
  $headersResult =3D $pac->readDocumentHeaders(getSessionVar('ticket'), =
getSessionVar('username'), null);
  $documentHeaders =3D $headersResult->getDocumentHeader();
 }
 catch (Exception $e)
 {
  log_write("[getDocumentHeaders] ERROR: $e");
  log_write("[getDocumentHeaders] Returning null...");
 }
=20
 $menu =3D '';
 $buildlist =3D array();
 $iter =3D $documentHeaders->iterator();
=20
 while ($iter->hasNext())
 {
  $header =3D $iter->next();
  $docClass =3D $header->getDocumentClassification();
  $urn =3D $docClass->getClassification();
  if (isset($doctypes[$urn]) && !in_array($urn, $buildlist))
  {
   $buildlist[] =3D $urn;
   $menu .=3D createMenuItem($doctypes[$urn]['display_name'], =
$doctypes[$urn]['menu_url']) . "/n";
  }
 }
=20
It gets a list of "Document Headers," then iterates over them.  Not too =
complex. I'm using PHP5 with Apache2: full info at  =
http://ajax.ping.chip.org/info.php <http://ajax.ping.chip.org/info.php>=20
=20
I'm happy to provide more information, just ask.  Any and all help is =
most appreciated.

OK this is first time I managed to get the .war successful deployed in
tomcat4. ;)


I just noticed one strange thing in handling the null-object:

--------- test.php5/instanceof.php ---------
If using *mod_php in apache* (using a browser and point it to
tests.php5/instanceof.php) while connecting either via
java_socketname=/var/run/.php-java-bridge_socket
or via
java_server=on

$list->add(null) has problems:

Fatal error: Uncaught [o:"java.lang.Exception: Invoke failed: [o:"[0,
one]"]->add((java.lang.Object)o:"null"). Cause:
java.lang.NullPointerException"] thrown in
/var/www/lokal/test/php-java-bridge/tests.php5/instanceof.php on line 16

php5-cli does not have this problem for some reason.

almost same thing seems to apply to
------ examples/php+jsp/oops.php -----
But this one *neither php5-cli or mod_php* like:
error: Uncaught [o:"java.lang.Exception: CreateInstance failed: new
java.lang.String(([B)o:"null"). Cause: java.lang.NullPointerException"]
thrown in /var/www/lokal/test/php-java-bridge/examples/php+jsp/oops.php
on line 6

first one seems kind of strange to me...

FYI I am using php5.0.4

Re: [Php-java-bridge-users] compiling on debian/gcc4 transition

Yes, I am a fool. :-<
Makefile is created by autoconf/configure whatsoever and of course
reflects the the CC,CXX environment vars I do set.

Still I think I haven't noticed this before:
-----------snipp----------------
configure: WARNING: YOUR GCC INSTALLATION IS BROKEN. It tries to link
with the same library for -m32 and -m64 builds. This may result in a
"wrong ELF class" error at runtime. Although you can work around this
bug at runtime by changing the LD_LIBRARY_PATH, we recommend to
re-install the gcc compiler before youcontinue to install the PHP/Java
Bridge.
----------snapp------------------

Everything seems to work now using gcc3-3 and g++-3.3 as the
libs(java,php5) are all compiled with gcc-3.x. Don't know if it would
work with gcc-4.0.

Since I use the 'make CFLAGS="-m32"' now probably I shouldn't have any
problems but still I'd like to know about that message, which sounds
somewhat scaring to me.

Cheers,
Peter
