They aren't ready yet. They will be used in the
Eclipse IDE and debugger.

One problem with these stubs is that PHP currently
handles some method names like exit(), put() etc
specially. This might change in PHP6.

We can set it up, if someone is willing to maintain
it.

you don't need java knowledge to invoke methods from
Java libraries. In fact you don't even need Java to
call out to Java libraries, if you have a recent
version of gcc installed (Linux only).

require_once("java/Java.php") 

is enough.

with

require_once("java/Java.php");
java_require("/path/to/myLib.jar;...);
$myClass = new Java("myLib.myClass");
...

The low-level interface is:

require_once("java/Java.php");
$string = new java("java.lang.String", "hello");
$ar = java_values($string->toCharArray());


The high-level interface:

require_once("java/java_lang_String");
$string = new java_lang_String("hello");
$ar = java_values($string->toCharArray());

You must use the full qualified name. For example:

  $handle = new Java("com.foo.something.Utility");

You can see the name by opening the .jar file with
winzip for example.

Re: [Php-java-bridge-users] tomcat - using php4

[<php...@li...>]

Hi,

[please excuse the delay]

I am sorry, but I could not reproduce this problem
with php 4.

I have installed the latest tomcat version
(http://ftp.uni-erlangen.de/pub/mirrors/apache/tomcat/tomcat-5/v5.5.20/bin/apache-tomcat-5.5.20.exe)
and downloaded and copied the current PHP/Java Bridge
("JavaBridge.war") into 

C:\Programme\Apache Software Foundation\Tomcat
5.5\webapps

downloaded and extracted the current PHP4 version to
c:\php and changed

C:\Programme\Apache Software Foundation\Tomcat
5.5\webapps\JavaBridge\WEB-INF\web.xml 

to

       <init-param>
        <param-name>php_exec</param-name>
         <param-value>C:\php\php.exe</param-value>
       </init-param>


After that I was able to run PHP4 applications within
tomcat.

The only problem I see is that the documentation shows
forward slashes, which is something that doesn't work
on windows. But this is a minor problem, imho.

You don't need a php_java.dll to run php from java. 

The PECL extension is only necessary for PHP4 and only
if you want to embed java statements into your PHP
pages.


> So I try c:\php\php.exe in web.xml and get "Fatal:

That's okay, see above. You probably use an old
version of the PECL extension.


> PHP 4.4.2 too old.
> For PHP versions < 5.1.4 install the PECL extension,

Yes, the pure PHP implementation currently only works
with php 5.1.4 or above. If you want to embed java
statements into your php pages, you must install the
PECL extension from sourceforge.


> Try the url in the error msg above and search it for
> PECL without luck

The PECL extension is packaged within the
JavaBridge.war.


> tried copying php_java.dll and php_java.jar 

These versions are 4 years old and don't work anymore.
Don't use them. Please use the most recent versions of
the PHP/Java Bridge and the PECL extension.

[Php-java-bridge-users] PHP Pear classes versus Java classes

[<php...@li...>]

What are the purpose of the PEAR style php stub classes that I  
created during the install of PHP-Java Bridge?

For example, if I do the following in a HP script:

$request = new Java("java.util.HashMap");

I can then use the "put" method to stick keys and values into this  
special Java Style array.

$request->put( "key", "value" );


But, I can also do the following:

require_once('classes/java_util_HashMap.php');
$request = java_util_hashMap();

But cannot do the "put" method to get values into the variable.

$request->put( "key", "value" );

This gives me a "NoSuchMethodException" error?

So I guess I just don't understand what these php stubs are for?  Can  
anyone explain?  Also, is there an official BBS style forum anywhere  
for posting help -- the mailing list seems outdated?

Thanks,

Jon

Re: [Php-java-bridge-users] Installation question/configuration (Apache/PHP/Jboss)

[<php...@li...>]

Thanks for your reply.

I now have successfully called an EJB3 Stateless Session Bean using this fantastic bridge in Jboss 4.0.4.GA (ejb3 install).  

I am however, having a little problem with logging - as soon as my EAR with a modified WAR (i removed all the files not necessary for my deployment) is deployed my console locks up.  I have managed to connect to the log4j output using Chainsaw so I know things are still working.  Has anyone else had similar problems?  Found any solutions - I think it's probably a property I haven't passed over when starting Jboss for a port or something...

We should probably encapsulate them, for example with

  require_once("java/Java.php");

It should work; I have tested the sample against the
current jboss release. There's a FAQ entry for it.

Please see the JSF examples for more information how
to use IOC (Fowler calls it "dependency injection").

I think Spring directly supports JSF beans, so that
should be pretty easy.

Re: [Php-java-bridge-users] Installation question/configuration (Apache/PHP/Jboss)

[<php...@li...>]

HI am such an idiot - I don't need the java/*.php files, I just needed to remove the line:

require_once("java/Java.php");

from the top of the sample pages...

So now I know I am using the c-based extension and I can run the most of the examples.

I am, however, getting a javax.naming.NameNotFoundException when I try the document example.

I am running with Jboss.

BTW - Has anybody had any success with using this bridge with Spring beans (in Java) if so, how do I go about accessing these?  Code example will be great.

Thanks

    # Static content

    (more like the above - including   _/*.php)

I am not really sure if I need the JkAutoAlias also..

[Php-java-bridge-users] I am a total Java dufus!

[<php...@li...>]

Hi all.

The title of the email says it all!  I know PHP like the back of my  
hand, but know little to nothing about Java.  I was able to compile  
and test the bridge for OS X Server, but I am running into a brick  
wall trying to understand how to create calls to Java objects  
(libraries, JAR's, or whatever they are called) and could use a  
little help from you experts.

Hopefully some of you can answer a few questions for me to get me  
started (ill try to be brief):

1) What are the standard "include" files I need at the top of each of  
my PHP scripts to utilize the Bridge?

2) How do I gain access to certain Java methods in my PHP scripts?   
For example if I want to convert a string read from a file into an  
array of values I think I would use $array_var->toCharArray 
($string_var).  I believe I need the "java.lang.string" library/class  
thing (found this in the Java API docs at Sun.com) but I cannot  
figure out how to enable this class or method in my PHP scripts?

3) I cannot figure out how to instantiate a new class or object.  For  
example a Java API we need to access has a file called  
"cybsclients15.jar".  I used a "java_require 
('......cybclients15.jar')" which seems to work (I didn't get any  
errors).  So how do I call or access the classes in that file?  For  
example, there is a class called "Utility" which in turn has a method  
called "read") in the JAR file.  I tried the following:

<?php
java_require("/Library/WebServer/Documents/cj/simapi-java-5.0.0/lib/ 
cybsclients15.jar");
$handle = new Java("Utility");
$props = $handle->read("config.properties");
?>

This is supposed to create a handle to the class called "Utility" and  
then let me use the "read" method to read a configuration file into  
an array.  All I get is the following error that seems to tell me the  
class does not exist:

Fatal error: Uncaught [o(Exception):"java.lang.Exception:  
CreateInstance failed: new Utility. Cause:  
java.lang.ClassNotFoundException: Could not find Utility in

Hi,

I am wanting to use your php-java-bridge to share httpsession data between a php application and a j2ee application and also for the php applicaton to communicate with some java session facades as an alternative to SOAP based calls.

I have had mixed success with the various configurations described in the documentation and would appreciate comments on the most optimal solution.   I am finding the documentation a little confusing :(

Re: [Php-java-bridge-users] tomcat - using php4

[<php...@li...>]

On the forward slashes, turns out you might have been on to something
there.

Chgd web.xml to use back slashes and got some different results

When set to:
<init-param>
 <param-name>php_exec</param-name>
 
<param-value>C:\Apache\Tomcat\webapps\JavaBridge\WEB-INF\cgi\php-cgi-x86
-windows.exe</param-value>
</init-param>

I get a phpinfo page with "PHP Version 5.1.3-dev" in the header, and 21
instances of 'php-cgi-x86-windows' (no .exe or .dll extension listed..)
running in in my task manager window.  If I shut TC down then they
terminate correctly as well.  This is progress

Now I'm fishing around abit to see if I can stumble across a solution, I
try 'php-4-java-x86-windows.dll' in place of php-cgi-x86-windows.exe in
the web.xml param-name value.  Restart TC and get:

javax.servlet.ServletException: An IO exception occured. Probably php
was not installed as "/usr/bin/php-cgi" or "c:/php/php-cgi.exe"
 or
"C:\Apache\Tomcat\webapps\JavaBridge\WEB-INF\cgi\php-cgi-x86-windows[.sh
]|[.exe]".
Please see "php_exec" in your WEB-INF/web.xml and WEB-INF/cgi/README for
details.
	php.java.servlet.PhpCGIServlet.doGet(PhpCGIServlet.java:546)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:689)
	javax.servlet.http.HttpServlet.service(HttpServlet.java:802)

Makes sense, it seems to need an executable of some sort.

The only other .exe file that I have in the cgi dir is the launcher.exe
file that I copied in from the IBM link you provided.  Changing web.xml
to use that results in the test.php page hanging with out reloading and
52 instances of php.exe running and visible in the task manager window.
Stopping TC does not terminate the 52 instances of php.exe

So I try c:\php\php.exe in web.xml and get "Fatal: The loaded java
extension is not the PHP/Java Bridge" with 20 instances of php.exe
running.  Stopping TC terminates the php.exe instances correctly

Copy php.exe from c:\php to the cgi subdir and repath the web.xml file
and I get:
PHP 4.4.2 too old.
For PHP versions < 5.1.4 install the PECL extension, see INSTALL
document from http://php-java-bridge.sourceforge.net/INSTALL.
Or set the path to the PHP executable, see php_exec in the
WEB-INF/web.xml

Hmm, running php.exe from 4.4.4

Try the url in the error msg above and search it for PECL without luck,
tried copying php_java.dll and php_java.jar into the cgi subdir
alongside php.exe, but the only way to get something that is close to
working is to set the param-name value to php-cgi-x86-windows.exe, but
it reports 5.1.3

Hope this helps

Mike

You think it's a bug vs. "pilot error" on this end?

I'll try the backslashes and get right back to you

Mike

Re: [Php-java-bridge-users] tomcat - using php4

[<php...@li...>]

Hi Mike,

thank you very much for this bug report. 

I haven't looked carefully enough at the error message
you've given. The exception is caused by a bug in the
CGIServlet, which requires a File.separator instead of
a slash.

I have created a ticket for this bug, please see
http://sourceforge.net/tracker/index.php?func=detail&aid=1574648&group_id=117793&atid=679233

As a workaround please use a backslash to specify the
path, e.g.:

  c:\windows\php.exe

I will check this with the author of the CGIServlet so
that we can publish an updated PHP/Java Bridge in
december.

Jost Boekemeier

Re: [Php-java-bridge-users] How to call a method with parameters?

[<php...@li...>]

Hi, Jost.

Thanks for your tremendous contributions to the PHP and Java user
communities.

Your reply actual gave me the answer to my problem.  Lately I've gotten used
to using PHP functions with pre-defined default values for arguments that
are not specified when the function is called.  The Java method I was trying
to call had a few optional parameters, and I just left them off, foolishly
thinking they would get filled in by default... and that was causing the
error.  Once I gave it all the parameters it expected, it worked fine.
Silly mistake!

Once I overcame that, I had another problem which I'll outline here for
posterity:
I couldn't get the "java.class.path" value defined properly until I came
across these two bits you posted in 2005:
"According to the README it is java.classpath" and "Please don't forget the
double-quotes"
http://www.thescripts.com/forum/thread11467.html

"java.classpath" vs. "java.class.path" -- There's probably a lot of
confusion about this since http://php.net/java states it as
"java.class.path" but apparently JavaBridge requires "java.classpath"

Leaving off the quotes might be another common problem since lots of
settings in php.ini don't require them -- for example setting extension_dir.
But java.classpath didn't work for me until I added the quotes.

Thanks again.

-Kevin

I've edited web.xml and added a path to php-cgi-x86-windows.exe within
the php_exec params, restarted TC but still have the same 500 error

> Are you sure that php.exe is a cgi binary? IMHO the cgi binary is
called php-cgi.exe.

Downloaded PHP 4.4.4 from php.net and there is no file inside the
release named php-cgi.exe

> However, I think it is best to download and to install the php
integration kit for windows and use the launcher.exe so that the
PHP/Java Bridge can use the FastCGI interface instead of CGI:
http://www.alphaworks.ibm.com/tech/phpintwasce/download

Ok, I've got the kit downloaded, copied only launcher.exe into the
webapps/JavaBride/WEB-INF/cgi dirand have updated the php_exec param in
webapps/JavaBridge/web.xml to point to launcher.exe, restarted TC and
end up with the same 500 problem

Is there a config parameter that I'm missing?  Am I the only one trying
to run the bridge within a TC/Win2k env?

Re: [Php-java-bridge-users] How to call a method with parameters?

[<php...@li...>]

Hi Kevin,

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

There is something I don't understand, the prototype
definition you've given requires 6 arguments, but
you've passed only 3:

> public static ExampleResult execute(java.lang.String
> ID, java.lang.String
> Name, java.lang.String PW, java.lang.String
> extraParam1, java.lang.String
> extraParam2, java.lang.String extraParam3)

> ->execute('123', 'John Doe', 'myPassword')


However the error message lists the three param proc
as a candidate, so your code should work. Can you
please open a problem report (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
and set the java.log_level to 6, re-start the backend
and append the log at the end of the ticket?

The log will show the reason why the bridge has
discarded the potential candidate.

Jost Boekemeier

[Php-java-bridge-users] How to call a method with parameters?

[<php...@li...>]

Hello.  I've been trying to figure this out for a few days now, and I'm so
totally stuck that I really need to ask for help before I go nuts.

I have a .jar file with the following information given in the
documentation:
-----------------------------------------
example.jar

java.lang.Object
 |
 +- example.client.ExampleRequest

Method:
public static ExampleResult execute(java.lang.String ID, java.lang.String
Name, java.lang.String PW, java.lang.String extraParam1, java.lang.String
extraParam2, java.lang.String extraParam3)
-----------------------------------------
... and the installation instructions say it needs to go here:
/opt/example/lib/


Question:  How do I call the execute() method and pass it the parameters it
needs?
I always get "java.lang.NoSuchMethodException" even though the method
definitely exists.  Is it because I'm not calling it correctly?


1) If my PHP code is this:
java_require("/opt/example/lib/example.jar");
$example = new Java("example.client.ExampleRequest");
$result = $example->execute('123', 'John Doe', 'myPassword');

I get this in the Error log:
java.lang.NoSuchMethodException: execute(o(Request$PhpParserString),
o(Request$PhpParserString), o(Request$PhpParserString)). Candidates [public
static
example.client.ExampleRequest.execute(java.lang.String,java.lang.String,java

Can anyone see what I'm doing wrong?

It is called php-cgi-x86-windows.exe.

Doesn't work. The command line interface only works on
the command line. :) You need the php-cgi.exe.

Are you sure that php.exe is a cgi binary? IMHO the
cgi binary is called php-cgi.exe.

However, I think it is best to download and to install
the php integration kit for windows and use the
launcher.exe so that the PHP/Java Bridge can use the
FastCGI interface instead of CGI:
http://www.alphaworks.ibm.com/tech/phpintwasce/download

Basically the windows version of PHP has been compiled
without a standalone fast cgi server; the -b flag is
missing in the windows php binary. Until the PHP
people add this capability to the windows version of
php, the above launcher.exe is required to run PHP
efficiently on windows.

This probably means that no HTTP header fields were
sent, which may mean that the bridge uses the CLI
instead of the CGI version of PHP.

I cannot find any file in the php release named 'php-cgi.exe'.  I
believe that php-cgi.exe is php5...  I've tried using a path to the cli
(c:/php/cli/php.exe) version and the cgi (c:/php/php.exe) version of
php.exe in the C:\Apache\Tomcat\webapps\JavaBridge\WEB-INF\web.xml file
(uncommented lines 58-61, and updated the value) but both result in an
exception when I try to run the test.php page:

note The full stack trace of the root cause is available in the Apache

I'm obviously still missing something, any ideas?

Re: [Php-java-bridge-users] tomcat - using php4

[<php...@li...>]

Hi,

please excuse the delay. I assume you're running setup
#6 (see
http://php-java-bridge.sourceforge.net/README).

It is possible to adjust the php_exec option, see
WEB-INF/web.xml. It defaults to
WEB-INF/cgi/php-cgi-<arch>-<os>, which is PHP 5.1. You
can set it to c:/php-cgi.exe for example.


> don't want to run the slower pure PHP implementation

The pure PHP implementation needs PHP >= 5 anyway.
When you use an accelerator technology, the pure PHP
implementation isn't much slower than the C-based
implementation. Round-trips are most expensive, but
they can eliminated by sending the Java() statements
in a single stream, e.g.:

java_begin_document(); 
  java statements; 
java_end_document();

So I think the lack of performance is not a good
argument to dismiss the pure PHP implementation. :)

Jost Boekemeier

Class.forName("name") 

loads name from the bootstrap classloader, so
java_require() has no effect. -- One could expect that
some default class loader, for example the class
loader from the current Thread context is used. But in
many areas Java simply doesn't work as one would
expect.

Please either use Class.forName with an explicit
classLoader argument (you can obtain the current class
loader from the current Thread) or simple use:

new Java("name);

instead.

Btw: Your .ini entry java.classpath=foo.jar;bar.jar
probably didn't work because the above semi-colon
starts an one-line comment.

Subject: tomcat - using php4


running TomCat 5 on Windows 2k, I've got the app up and running but the
test page shows that the version of php is php5 but I'd rather run php4.
The php/java bridge docs read vague to me (new to this) about how I can
config the bridge to run PHP 4 vs 5 without rebuilding the app.   I
don't want to run the slower pure PHP implementation
 
any reference doc that someone can point me to that would show me the
config setup for running php4?

you can only convert Java libraries which do not
depend on external libraries.


Please either use the low-level interface, i.e.

java_require("foo.jar;bar.jar");
new Java("com.Foo", "FOO");

instead of

require_once("foo/com_Foo.php");
...
new com_Foo("FOO"),


or copy all external references into the jar file
which should be converted.
