Hi, where you can get the file php-5.0-java-x86-windows.dll or java-x86-windows.dll to test the bridge between php and java, and that the war is not found.

Thank's

It probably isn't.

http://localhost:8080/test/env.jsp/tail?a=b
=>
URI          /test/env.jsp/tail
ServletPath  /test/env.jsp
PathInfo     /tail
QueryString  a=b
a            b

>env.servletPath = (String) req.getAttribute("javax.servlet.include.servlet_path");
>if (env.servletPath == null) {
>env.servletPath = req.getServletPath() + req.getPathInfo();
>}

So PATH_INFO should be null for your request.  The
super.setupRequestVariables() sets

env.servletPath = (String)
req.getAttribute("javax.servlet.include.servlet_path");
if (env.servletPath == null) env.servletPath = req.getServletPath();

which is equivalent to your code.

I downloeded 6.2.1.RC3 http://sourceforge.net/projects/php-java-bridge/files/Binary%20package/php-java-bridge_6.2.1rc3/exploded/JavaBridge.jar/download

We use Tomcat with our JBOSS.

Well the "destop guide" shows how to extend your Java desktop
application to allow scripting.

For web applications please follow the other guide (web front-end =>
servlet/jee back-end).

You *can* use JavaBridge.jar instead of a servlet back end. But note
that the standalone JavaBridge.jar container isn't as efficient as a
servlet or JEE container.

Hi,

you say "latest" PHP/Java Bridge version. I assume it is version
6.2.1RC3. -- latest stable is 5.4.something.

> env.servletPath = (String) req.getAttribute("javax.servlet.include.servlet_path");

We've made a change regarding this, please see

I don't think jboss uses its own servlet container. Do you use jetty or tomcat?

Regards,
Jost Bökemeier

Hi,

JBOSS, and its own servlet container.  I wrote a servlet that replaced this in FastCGIServlet

  protected void setupRequestVariables(HttpServletRequest req, Environment env) {
super.setupRequestVariables(req, env);
env.servletPath = (String) req.getAttribute("javax.servlet.include.servlet_path");
if (env.servletPath == null) {
env.servletPath = req.getServletPath() + req.getPathInfo();
}
  }

And I can get to pages with https://localhost:8080/ctx/directory/directory/test.php now.

But not sure if I should do that ...

PS.  I don't know how to reply to my own email in digest mode...

Thanks.

Hello,

I'm new to php/java bridge and I'm wondering if I could use this fantastic project in a work of mine. The "problem" is the follow:

I have to create a Webservices running on a customized-centos to offer an access to some business operation.  My goal is to write the webservices in PHP (as I've already an Apache running on my distro) and write the business operations in java (to avoid my code to be read or edited). Business operations would be a collection of classes rappresenting database entities, classes to manipulate them and some other stuff. I could say I want to create a java-layer between php-webservices and database server. 

Reading at the installation guide, I've found out one could create a "desktop" java client and call it's methods and classes within php. I don't understand if it's my scenario (webservices + persistence-layer) or it's completely different. So, do I need to write something like the follow:

- a java-main class like

public class Test {
  public static final String JAVABRIDGE_PORT="8087";
  static final php.java.bridge.JavaBridgeRunner runner = 
    php.java.bridge.JavaBridgeRunner.getInstance(JAVABRIDGE_PORT);

  public static void main(String args[]) throws Exception {

    //some initializations go here?

   runner.waitFor();
    System.exit(0);
  }

  //and then write a contract for php
  public Model getModel(String modelName)..
  public boolean someStuff()   

} 

public interface Model{

	public boolean save();
}

-and within php

<?php 

require_once("http://localhost:8087/JavaBridge/java/Java.inc");

$dbLibrary = new java("Test");

$model = $dbLibrary->getModel("myModel"); //does it return a valid class with a valid db connection(if i setted it in the model)?

//do some stuff on model

$model->save(); //should it work?????

?>

? Is this the way? 

Thank you very much

Hi Ian,

> variable

the __destruct() hook lets you destroy external resources associated
with the current class instance. What you are looking for is the
__sleep() hook, which lets you save the object state.

Please see the PHP documentation for details.
Please see also: http://bugs.php.net/bug.php?id=49432

Hi,

Thanks for the response, although I don't quite understand what's going
on so please bare with me ;)

The site I am working is pure php but in order to process a particular
type of transaction I have to use a Java library.

I have placed all the code I need into a php class and call this when
necessary.  I have found that session variable set after using this
class aren't stored. (This was very frustrating to debug as you can
imagine.)

Could you tell me when and under what circumstances the java_shutdown()
function is called?  I may be able to alter my code to work around this
issue if it is necessary to run the session_write_close() at that point.
 I don't normally call this manually but let the main site __destruct()
function call handle the saving of all my objects into a session
variable - which is then rebuilt when another page is called.

Thanks for your assistance.

Ian

Hi,

not if we want to get PHP/Java Bridge 6.2.1 through the release tests,
no. Please see http://php-java-bridge.cvs.sourceforge.net/viewvc/php-java-bridge/php-java-bridge/tests.php5/session_write_close_bug.php?revision=1.5&content-type=text%2Fplain

This problem should be solved on PHP level, please see
http://bugs.php.net/bug.php?id=46451

Why and how do you want to access the session after the evaluator shutdown?

Regards,
Jost Bökemeier

Hi,

Is there a way to call the Java Bridge from php so that
session_write_close() is NOT called on java shutdown. This was causing
problems with my application by saving the session before I had finished
using it.

I have commented out the offending line in java.inc.php but don't want
to have to remember to do this on every upgrade.

Regards

Ian
-- 

  Jost, all -

I have been doing more investigations into why the php-java bridge is 
not working as I would expect, but so far I got no joy in why it is 
failing...  So I thought I would send in a concise version of the jsp 
code/file I am trying to set up, and see if you or anyone else can spot 
what I am doing wrong....  (this also shows the interplay between jsp 
variables and the Javascript/PHP scripts, which is why I am choosing to 
use JSP)

What I am discovering, is that as expected the method evalPHP is being 
called (twice). The call to the function - outputJavaScript in my PHP 
script does indeed return a Javascript statement (via the internal call 
to pass_to_php_backend), which is a String variable, and I can in fact 
put an echo statement just before the return and see that the expected 
Javascript statement is produced.  But what is NOT happening is that 
this returned string is produced in the output document, at the point of 
call to evalPHP.  (I have placed calls to alerts to show this is indeed 
what is happening, as can be seen in the following code.)

Thoughts?  Thanks again in advance for helping me with this...   Marc...

I am sorry but I don't follow you...  What should be a method?  My PHP 
script? If that is what you are referring to, then how will that affect 
the placement of the output from the script when it is evaluated? And 
how do I call it? Perhaps I need a better example to help me grok this?  
Keep in mind that what I am trying to accomplish is to executed an 
embedded multi-line PHP script inside a Javascript segment, all of which 
is inside a .jsp file.....  At the moment the PHP script is being 
executed, but the output, being done via echo statements in the script 
(and called PHP functions) is all being placed at the beginning of the 
output document, not at the place where the evalPHP call is made...

Also, are the changes I made to the evalPHP function correct? I presume 
that the first argument of evalPHP (String arg....) is the string that  
contains the actual script that I want to execute. I have concatenated 
all the PHP script lines into a single String variable and this is what 
I pass to evalPHP.

Thanks again for all your time and help!   Marc...

Hi Jost -  Hmmmm  since the method evalPHP, as you sent it to me in your 
previous email, is declared private static final, one cannot use the 
'this' parameter. Do you see any problem with removing the static final 
from the declaration? That allows this to be called in the context of 
the instance of the servlet that is running. But doing so will then 
cause the parameters of evalPHP - application, request, and response to 
be undefined since this code is within the Declaration section of the 
servlet. I think the application parameter can be retrieved via a call 
to this.getServletContext(), but the only way to get the request and 
response parameters will be to pass them in to the evalPHP method.  Do 
you concur? I am thinking the following -

private String evalPHP(String arg, HttpServletRequest request, 
HttpServletResponse response) {
     CompiledScript instance =
(CompiledScript)((java.security.cert.CertStoreParameters)script).clone();
     instance.getEngine().put("script", arg);
     OutputStream out = new ByteArrayOutputStream();
     Writer writer = new OutputStreamWriter(out);
     instance.getEngine().getContext().setWriter(writer);
     instance.getEngine().setContext((ScriptContext)new

PhpCompiledHttpScriptContext(instance.getEngine().getContext(),this,this.getServletContext(),request,response));
     try {
         instance.eval();

     } catch (ScriptException e) {
         throw new RuntimeException("bleh!");
     }
     try {
          writer.close();
     } catch (IOException e) {
         throw new RuntimeException("bleh!");
     }
     String result = out.toString();
    return result;
}

I have gone ahead and tried this, and it almost got me to what I want. 
But one problem remains and I don't grok the code enough to be able to 
solve on my own, so need a bit more guidance. The PHP script that I want 
to embed in the middle of a Javascript section generates a line of 
Javascript that I want the servlet to write back out, at the point where 
the call to evalPHP is made. But when I execute this jsp servlet, the 
generated Javascript from the PHP script is being put out at the very 
beginning of the document. (I was also surprised that the return result 
from evalPHP is null....)

    Thanks again for all your help!   Marc...

Hi again,

insert a

  instance.getEngine().setContext(new
PhpCompiledHttpScriptContext(instance.getEngine().getContext(),this,application,request,response));

before calling instance.eval(). Otherwise JSR223 will use the default
context, which isn't very usable in a web-context.

Hi Marta,

first of all, requestDispatcher.forward() lets you forward POST
requests. But I don't think this works with include().

Second: some application servers like Sun Java AS 9 have a very small
thread pool size. If you open a loop-back connection to the back end,
you risk to lock up the whole application server.

AS 9 pool size defaults to 5, which means that 3 concurrent user
requests *will* lock up your application server forever, if your
servlet opens a HTTP URL connection back to your application server.
Apache's pool is larger, it defaults to MaxChilds=150. Send it more
than 75 concurrent requests and it will stop responding forever.

So file_get_contents(localURL) or a loopback java.net.URLConnection to
the back end is not an option. Forget that.

If your JSP has been written properly, it separates the business- from
the UI logic. So it should be easy to call the business methods from
your PHP servlet as well. If not, your only option is to refactor the
JSP or to duplicate some of its functionality.

A third option (but rather lo-tech) is to ask the browser to deliver
the content of your JSP and to deliver it to your PHP servlet using
AJAX.

Regards,

Hi,

please take a look at the jsr223.jsp from the documentation download.

> <?php require_once("java/Java.inc");

It's a JSP, so you need to use JSP syntax:

<%@page import="javax.script.*" %>
<%@page import="php.java.script.servlet.PhpCompiledHttpScriptContext" %>

<%!
private static final CompiledScript script;
static {
	try {
		script =((Compilable)(new
ScriptEngineManager().getEngineByName("php"))).compile(
        "<?php echo eval(java_context()->get('script')); ?>");
	} catch (ScriptException e) {
		throw new RuntimeException("bleh!");
	}
}
private static final String evalPHP(String arg) {
    CompiledScript instance =
(CompiledScript)((java.security.cert.CertStoreParameters)script).clone();
    instance.getEngine().put("script", arg);
    OutputStream out = new ByteArrayOutputStream();
    Writer writer = new OutputStreamWriter(out);
    instance.getEngine.getContext().setWriter(writer);
    instance.eval();
    writer.close();
    return out.toString();
}
%>

<script type="text/javascript">
