4.4.0 - at least you can always ask new users to get latest version of
PHP to avoid bugs introduced earlier. I've tried to compile PHP myself
from CVS, but failed. And also I don't use any web-server - I want to
try mix of Java and PHP in standalone application.

Yes, sometimes. It will be nice if this application could detect
presence of PHP and link it dynamically regardless of PHP5/PHP4
differences and without additional path setup.

I like things like unzip and run. Like any lazy user I hate doing
things that could be automated or not intuitively setup by default.
Especially test-cases. =)

README is very long and contains a lot of information. Read 25k just
to find command line options (especially if there are not any) is a
waste of time. I thought it should be good for an application to
react on help/unknown cmd parameters to be user-friendly.

The bridge is not running under Tomcat or Apache - it is supposed
to be used for standalone application in my case. And yes - it is
windows.

I don't think it is easy, esp. for me. =) Probably It should be
easier to create a proxy Java object, which will call invokable
PHP functions where it needed. The problem is that I still unsure
if I've got the whole picture of this bridge and how to plug it
into Java application correctly.

Hi Peter,

[please excuse the delay]

Well, your GCC installation uses two different static
libraries for m32/64 but only one dynamic library. 
Depending on the processor architecture this may or
may not be a problem.  I have changed the message in
2.0.8RC5.

> know if it would work with gcc-4.0.

gcc4 should be able to compile the source. (other
distributions such as RedHat use gcc4 for a long time
now, so I don't think that this is an issue).

Hi William,

[please excuse the delay]

to the best of my knowledge this problem should be
fixed in version 2.0.8RC5. Please see the updated
INSTALL document for details.

Furthermore it should be possible to use the binary
RPM:

* Extract the "java.so" and "JavaBridge.jar" from the
binary RPM with the command:

  rpm2cpio php-java-bridge*.rpm | cpio -iduv

* Install PHP 4.3.2 or above and copy the "java.so"
and "JavaBridge.jar" into its extension folder.

* run the test.php with: php test.php


Regards,
Jost Boekemeier

Hi,

> Fatal error: Uncaught
> [o(Exception):"java.lang.Exception: 

In PHP4 the exception would be a warning which could
be suppressed with @

Example:

$null = @new java("java.lang.String", null);
$ex = java_last_exception_get();
echo "val: $null, ex: $ex\n";

The above code would display "val: , Object" in PHP4.

The above exception message ("Uncaught...") makes me
believe that you already use PHP5 or above.

First of all, thanks for his cool extension. I got it running within 5
minutes, and it works like a charm.

Except for one issue: I'm using it to run Lucene with PHP 4. Now, in certain
cases Lucene throws an exception, for example when the query parser can't
handle an invalid query. Then I get a message like

Fatal error: Uncaught [o(Exception):"java.lang.Exception: Invoke failed:
[o(QueryParser):"org.apache.lucene.queryParser.QueryParser@1f8c6df"]->parse(
(java.lang.String)o(String):"AND "). Cause:
org.apache.lucene.queryParser.ParseException: Encountered "AND" at line 1,
column 0. Was expecting one of:  ... "+" ... "-" ... "(" ...  ...  ...  ...
... "[" ... "{" ...  ... "] thrown in {/path/name} on line 37

I know there is java_last_exception_get(), but the fatal error occurs on
line 37, which is exactly where I call the (java) query parser, and then
script execution is terminated.

So, is there anyway to handle those cases gracefully (except for upgrading
to PHP 5)?

Thank you,

Michael

Hi Bharath,

you're right. The CGIServlet cannot handle post
requests. The code is there, but it seems that nobody
has tested this until now.

Please excuse the inconvenience, I'll fix this asap. 
(The CGIServlet was copied from tomcat, which was
probably a mistake...)

Please see PR#1291191
(https://sourceforge.net/tracker/index.php?func=detail&aid=1291191&group_id=117793&atid=679233)

Hi Bharath,

first of all thank you very much for this bug report.

Assuming that phpinfo shows that 

X_JAVABRIDGE_OVERRIDE_HOSTS  127.0.0.1:9980  
X_JAVABRIDGE_CONTEXT  1  

the null pointer means that the php_java.dll was not
able to send back the X_JAVABRIDGE_CONTEXT and that
the servlet has received the invalid context 0.

I could not reproduce this problem, but I have created
a ticket (#1291175) for this NP exception. Please see 
https://sourceforge.net/tracker/index.php?func=detail&aid=1291175&group_id=117793&atid=679233

Please attach the values for 
X_JAVABRIDGE_OVERRIDE_HOSTS  and X_JAVABRIDGE_CONTEXT
there and the method (POST or GET) there. If possible
please also attach the php_java.dll and the
php-cgi.exe you use.

Please also check why the bridge uses port# 9568 and
not 9567. Is it possible that you use an old version
of the php_java.dll with a recent version of the
JavaBridge.war backend? It might be that your
php_java.dll still sends a 32 bit value for the
context# and the backend always reads the 2 high
bytes, which are 0.

Jost Boekemeier

Subject: problem with Post

I have the java bridge setup as a webapp on tomcat. When I post a
request to a php bridge in the webapp, for some reason the post
variables seem to be lost. Get variables are reaching correctly.

To reproduce the problem drop the attached php file to the JavaBridge
web app on tomcat.

A session value is hard coded into the script. A GET value is also
hardcoded. Enter text into the text box to simulate POST vars. The
ideal output should be similiar to the one below:=20

POST Vars=20
Array ( [username] =3D> whateveryoutypedin )=20

GET Vars=20
Array ( [temp] =3D> 1 )=20

Session Vars=20
Array ( [tempvar] =3D> temp value )

I have also added phpinfo() to see what we get. Don't see a _POST var
Any idea?

Hi Shoan,

Are you sure that JavaBridge.war is installed and the
JavaBridge context is running?

If the context is not running, the client receives a
HTML error message which is similar to the bridge' XML
protocol, it crashes or hangs after that. (It is
difficult to catch this problem without validating the
response.)


What happens if you visit
http://localhost:8080/JavaBridge and then click on
test.php?

Jost Boekemeier

Hi,

I installed the latest php-java bridge 2.0.8RC2 on windows XP. PHP  
5.0.3.3 CGI/Fast CGI. I have set the required system variables viz.  
JAVA_HOME, CATALINA_HOME, PATH, SystemDir, SystemRoot.

On executing test.bat after starting tomcat, I get an error window  
"CGI / FastCGI has encountered a problem and needs to close. We are  
sorry for the inconvenience."  The result.html seems to be abruptly  
terminated and there are no java variables in it. Although, there is  
a new section for java as shown below:

java support     Enabled
java bridge     2.0.8RC2
java.log_level     4
java.hosts     127.0.0.1:8080
java.servlet     On
java status     running
java server     127.0.0.1:8080


Please let me know if you need more information to troubleshoot the  
problem.

Peace,
Shoan.

Hi,

> 1. BUG. There is no PHP4 version of library in

The PHP/Java Bridge does not work on threaded HTTP
servers, e.g. IIS, unless ZTS is switched on. 
ZTS is experimental in all versions below PHP 5 and I
know of at least 3 incompatible ABI's since 4.3.2.

So the question is: which version of PHP4 on windows
should we support? Isn't it possible to compile your
own php4 binary as described in the README?


> 2. About 80% of windows distributive size is

Yes, certainly. But is 3MB really too large these
days?


> 3. Patch to make test run even if unzipped not in
> c:/php5

Isn't it possible to adjust the php.ini accordingly?
One has to do this during the installation process
anyway. But the widgetTest.bat could be changed, of
course. 


> 4. JavaBridge.jar doesn't output any messages about
> it was started successfully

If you start it at log level 3 or above, as described
in the README, it will output to stdout or to a log
file.

"apachectl start" starts the apache server and the
bridge and "apachectl stop" stops both, please see the
README for details.  Since version 2.0.8 this works on
windows, too.

However, the recommended way to run the backend is to
start it via the php-java-bridge.service script (on
Unix) or via tomcat (on windows).

 
> 6. It would be good to have a ToC in readme.

Yes.


> Q1. Is it possible to extend Java class with PHP?
> I.e. make PHP class, inherited from one of Java?

The java_closure() call currently accepts only
interfaces, not classes. It would be nice if the Sun's
dynamic proxy would accept a class, but it doesn't. If
we want this, we must write our own proxy compiler.

Please see

Hi Raphael,

all pages are generated through tomcat, only the
content within the page is generated by php. Since you
use the default value for java.servlet which is:

java.servlet="/JavaBridge/PhpJavaServlet"

tomcat has set the path value to the app directory,
which is "/JavaBridge".

The reason why the bridge component truncated the
/JavaBridge to / was to disallow session sharing for
PHP pages which are outside of the app directory. The
current test is wrong, of course: /JavaBridge !=
JavaBridge, so the bridge has incorrectly changed the
path.

You can remove the strncmp from line#198 in
http://cvs.sourceforge.net/viewcvs.py/php-java-bridge/php-java-bridge/protocol.c?annotate=1.29

I have created a bug report for this, please see
PR1288025
(http://sourceforge.net/tracker/index.php?func=detail&aid=1288025&group_id=117793&atid=679233).

I will prepare a 2.0.8RC3 tomorrow evening.

I use Apache 2.0.53. Perhaps it is not clear: Both server use different
folders. The logical path is the same to avoid problems with the path
value in the cookie.

I wonder why it work in one direction but not the other way round. The
only difference is the path value. A workaround could be to set the path
always to / so the cookie is valid for the whole server. The port is imo
not relevant. Unfortunately I can not do it by myself because I don't
know if it is handled by the JavaBridge or in Tomcat.

We have a pretty complex application written in PHP which we need to
integrate into a Java Portal. The Portal runs in a OC4J and the PHP
application on an seperate Apache Instance on the same machine. Both
application have a own user management. If a user log in (the portal)
and then goes to the PHP application it need to know which user is it. I
thought the easiest way is to read the Java session and then map the
user data to the user of the PHP Application.

Raphael

interesting.  I didn't think about this scenario. I
assume you use IIS, which cannot JkMount the tomcat
folder, and manually redirect all .jsp requests to a
different server.


> Is this a bug in JavaBridge 

If we want session sharing between different servers,
we must strip off the server part from PHP_SELF,
please see protocol.c, setResultWith_context()

This raises some security concerns, though.

So before I change the code to strip away the server
part, I would like to see a use case. Can you please
explain why do need this?


Regards,
Jost Boekemeier

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 this would help.=20

Thanks

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.

Thanks Jost

Here is my configuration

Windows XP professional SP2
JDK - 1.4.2_05

I will use the work around for the time being

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.

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
