Re: [Php-java-bridge-users] Servlet PhpCGIServlet is not available

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

Hi Peter,

first of all thank you very much for this problem
report. Indeed, override redirect (which stops the
secure channel and opens a new socket connection to
8080 to obtain the session handle when java_session()
is not the first java statement in a script) doesn't
work anymore in 3.1.8. The reason is that it now needs
a security token which has been destroyed after the
first Java() statement.

The pure PHP implementation of the PHP/Java Bridge
code doesn't implement override redirect, so this
feature isn't portable anyway.

Please use java_session() as the first Java()
statement in a script, for example:

<?
...
$session = java_session();
$ob = new Java(...);
?>


Since the handle is cached, the following will also
work:

<?
java_session();
$ob=new Java(...);
$session = java_session();

?>


However, I will make a patch available which fixes
this problem. 

Regards,
Jost Boekemeier

Can you please open a problem report (please use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
and attach the relevant tomcat log there?

It's faster and more secure. And it should work with
any J2EE server or servlet engine, that's why I am
very surprised that it doesn't work with one tomcat
version. I think the tomcat log should reveil the
reason.

Jost Boekemeier

It wraps the original exception (jsr223 demands it).
Doesn't $exception->getCause() reveal the original

[Php-java-bridge-users] Problem accessing MySQL-JDBC-Driver

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

Hello,

php-java-bridge is a great tool. But now I'm having a problem with 
accessing a MySQL-database using jdbc which I was not able to solve.

I always get the message "java.sql.SQLException: No suitable driver 
Responsible" or class not found errors.

The problem occurs when I try to convert the java code
   Class.forName("com.mysql.jdbc.Driver");
and the "getConnection" into corresponding php-code.

Please see the code snippets and the provided system information for 
details.

I have tried several ours to solve the problem. So any help would be 
desperately appreciated... Any ideas?

   $conn = new Java('java.sql.Connection');

   // The following is working without errors. So the class must be 
there, I suppose...
   $mysql = new javaClass('com.mysql.jdbc.Driver');
   $mysqlinst = $mysql->newInstance();

Re: [Php-java-bridge-users] Servlet PhpCGIServlet is not available

Hi,
   
  interestingly I've got similar problems while upgrading to bridge 3.1.8. The tomcat error log contained NoClassDefFound messages suggesting that some essential classes were missing.
   
  It turned out that tomcat kept old classes in its work and tmp directory and it was using these classes instead of the new versions from the JavaBridge.war.
   
  Cleaning these directories helped, but I now get java.lang.SecurityException messages when accessing the java session store from apache...The sessionSharing.php example works, but my classes don't. the only difference I see is that my classes call java_get_session more than once. Is there a bug in 3.1.8?

have any idea how to fix this?

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

yes, the servlet doesn't wait for the context anymore,
so after one Java() statement the request object is
recycled. I have removed the context.waitFor() after
2.0.8 (see line 330 in
http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bridge/server/php/java/servlet/PhpJavaServlet.java?revision=1.25&view=markup)
because the request object isn't really useful at the
moment anyway. It doesn't carry any information about
the original request, etc. But we could forward the
necessary request options and let the servlet wait for
the Context, if needed.

After the first line the servlet and its associated
request object is recycled by tomcat and the bridge
runs with a context server which is more than 50 times
faster than sending PUT request.

You can switch off the pipe and socket context server
by running tomcat with the java options:

 -Dphp.java.bridge.no_pipe_server=true
-Dphp.java.bridge.no_socket_server=true 

(see
http://php-java-bridge.sourceforge.net/server/documentation/API/php/java/bridge/http/PipeContextServer.html
and
http://php-java-bridge.sourceforge.net/server/documentation/API/php/java/bridge/http/SocketContextServer.html)



> Is that the expected behaviour, even considering I

Yes. Even if the Pipe-/SocketContextServer is switched
off and the bridge must send a PUT request for each
individual Java() statement, the request and response
objects are recycled by the servlet engine. This means
that you can't store any values there, each PHP Java()
statement is executed in a fresh context, only the
session store stays the same.

This shouldn't be too difficult. However, I think this
is a feature which should also go into the bridge
code. I will create a new 3.2.x branch and add this
feature there.

Just forward both, the PHP and the JSP requests. This
will invoke the FastCGI machinery, which isn't much
slower than Apache (according to my tests it is even
faster than Apache's worker MPM).

Re: [Php-java-bridge-users] getting hold of HttpServletRequest obj as if php page was jsp

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

Jost - thanks for the informative reply.

I am running PHP in apache, and forwarding JSP pages (and the java  
bridge) through to Tomcat. So according to what you say below, that's  
not going to work well for me in any case.

However I tried to get  java_context()->getHttpServletRequest()  
anyway, just to experiment and see if that would get me anything  
interesting. Unfortunately that's raising exceptions:

<?php
     $request = java_context()->getHttpServletRequest();
     echo $request->toString();
     $uri = $request->getRequestURI();
?>

displays:

[o(String):"org.apache.coyote.tomcat4.CoyoteRequestFacade@1707653"]
Fatal error: Uncaught [o(Exception):"java.lang.Exception: Invoke  
failed: [o(CoyoteRequestFacade)]->getRequestURI. Cause:  
java.lang.NullPointerException

Responsible VM: 1.4.2_06@http://java.sun.com/" at:

Is that the expected behaviour, even considering I am forwarding the  
embedded php java() statements?

I have a feeling that I am going to need to implement my own  
HttpServletRequest in any case - why, because I'll probably be  
implementing what used to be full JSP pages as in-page modules within  
a CMS (Joomla or Typo3, probably). Thus the URLs of the new system  
will be a lot different to the old system (the CMS will use parts of  
the URL for its own navigation, which I won't want to pass through to  
our java backend), and I will probably have to construct "fake"  
HttpServletRequests to match what the backend is expecting.


Just out of interest, how would I get Tomcat to interpret the php  
pages instead of apache?
- Is there an easy way to implement this with our current setup (we  
have stock apache running php, passing jsp pages to Tomcat on port  
8080 with jk)?
- Can one pass php pages through to Tomcat using the same mechanism  
as for JSP?
- If so, would this cause much of a performance hit?


Thanks for any help
Cheers,
Stephen Brandon

Can't the <a

be used for this?

Yes, this should work fine.

You can access the HttpServletRequest from here:
http://php-java-bridge.sourceforge.net/documentation/PHP-API/html/java_8c.html#doc26
and
http://php-java-bridge.sourceforge.net/server/documentation/API/php/java/servlet/Context.html#getHttpServletRequest()


> Is it clear what I am trying to achieve? 

You haven't mentioned if you run PHP within your
servlet engine or within Apache or IIS. If you run PHP
within your servlet engine, 

$request = java_context()->getHttpServletRequest();

will just work.  

If you run PHP in a HTTP server and only forward the
embedded php java() statements, things will be more
difficult, because the bridge doesn't pass all
information to the back-end. For example a request

GET http://host.com/foo/bar.php?param=...
will cause the bridge to send a HTTP PUT request:
PUT http://127.0.0.1:8080/foo/bar.phpjavabridge

This means that you currently cannot retrieve the
method() and the params from the request. -- But the
bridge could forward them, if you need this.

[Php-java-bridge-users] getting hold of HttpServletRequest obj as if php page was jsp

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

Hi,

I am looking at using the PHP Java Bridge to help to transfer a whole  
lot of JSP pages into a PHP-based CMS. Installation went fine.

The JSP pages are well structured with a set of java classes as a  
backend, such that the JSP page basically has to call a method with  
the HttpServletRequest request object as argument, and returns arrays  
of data to display on the page.

Therefore it doesn't seem too difficult to imagine making a PHP  
module/class which simply calls the same java method via the PHP Java  
Bridge, then does the layout pretty much like the JSP file used to.

HOWEVER the first stumbling block is that because we're no longer  
operating in a JSP sort of context, we don't appear to have an  
HttpServletRequest to pass to the backend any more, which we require  
to get hold of the URL string, cookies, etc.

I'm not keen (at this stage) on reprogramming all the java classes to  
use an alternative source of input data, if it would be possible to  
get hold of a HttpServletRequest that we can pass in as before.

I had a look at creating one programmatically (faking it), but it's  
not a class but an interface, and there are potentially some issues  
with session ids etc that I don't know about.

Is it clear what I am trying to achieve? Does anyone have any hints  
for how to create a HttpServletRequest, get hold of one, or otherwise  
pass URI/cookie/session data through to our backend, that is used to  
receiving HttpServletRequest objects?

Many thanks,
Stephen Brandon

This may work when you don't compile in the source
directory. But depending on the PHP or autotools
version you could end up with a mix of old and new
code.

Don't look at the SF stats, they're all wrong. :)

The Release-3-1-8 tag is now there.

No idea. I've just compiled and tested the CVS head on
a ppc64 running Suse Linux. There were no compilation
issues and both, the java.so and the java/Java.php ran
the bench without problems.

[Php-java-bridge-users] install-probs and tags, status of CVS

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

Hi Jost,

I am really astonished be the work that you are doing with the
java-bridge. Since it is still constantly improving I jump in on more
recent versions every once in a while to keep up.

I like to use CVS for this since it is so easy to update or switch
between tags/releaes/branches and alike.

Running an update today (3.0.8-dev to 3.1.8-dev) I had a lot of trouble
getting everything to work. In this case I tried to switch to some
reliable/stable code-base and therfor tried to find an appropriate tags
in CVS.

Sadly you seem to have quit tagging or branching in CVS for quite a
while and what even was worse to me now is that from your CVS-log
messages it seems that 3.1.8 was just created really recent, however the
file-release for 3.1.8 on sf date back to 08/2006. Therefor I didn't
find any stable tags/date in CVS.

So as last chance I tried it with the source-tarball from SF.

The good news: It is just working as intended. :->

The bad news: It seems I am not able to fit my CVS-checkout for exactly
this code by tag or date or neither can I try to find out about the
problems I ran into. :-< [1]

Anyway I would really greatly appreciate the usage of tags/branches in
CVS. ;)

Yes, I know CVS is mostly intended for developers only...

Greets,
Peter

java.io.FileNotFoundException: /dev/shm/.php_java_bridge

Hi again,

are you sure this web context exists?


If not, change java.servlet=User to

The tomcat HTML error message "Context doesn't exist"

The file "java_lang_System.php" does indeed exist in my "classes"  
directory.  So it looks like it is just a naming issue (at least with  
Power PC machines).  I will have an Intel Mac laptop at the end of  
the month so can test the same install there to see if there is a  
difference.

Okay, so it is just an issue with where you do an include.  I was  
concerned that the bridge software itself would look for the "rt"  
directory and run into problems if it could not find it.

Hi,

you could set the bootPath to an empty string in line
103, see
http://php-java-bridge.cvs.sourceforge.net/php-java-bridge/php-java-bridge/server/php/java/bridge/Snarf.java?view=annotate&sortby=date

In the future we should avoid creating stubs if the
files already exist.


> I double checked and there is no RT directory like
> you mentioned.

Thanks. I think the easiest way to fix this is to
check if the created directory contains
java_lang_System.php. If it does and the dir doesn't
have the name "rt", rename it. I have created a ticket
for this bug:
http://sourceforge.net/tracker/index.php?func=detail&aid=1557227&group_id=117793&atid=679233

> am not sure how this affect the overall
> installation? 

The Lucene search and Itext PDF examples use something
like:

require_once("rt/java_lang_System.php");
require_once("rt/java_awt_Color.php");

When rt doesn't exist, those examples will not work.

> to the bridge software because of its name?

The require_once() in the above examples will fail.

> > Do you use a power or intel mac?
> I am currently running this on a dual G4 powerPC 

I thought so. There's a chance that the intel macs are
more compatible with the Sun VM.

Hi,

first of all thank you very much for the feedback.

> non-zts-20050922/JavaBridge.jar --convert
> This ran for about 4 minutes before completing.  

It creates PHP proxies for the classes found in boot
classpath and for the additional libraries specified
on the command line. Depending on how many classes it
has to convert and how fast your machine/VM is, this
may take some time. On my devel. machine the command
completes in less than two seconds. But even 4 minutes
shouldn't be a problem because one usually calls this
command once; during installation.


> directory (/urs/local/php5/lib/php) and found

These are created from the essential .jar files from
the boot classpath. But rt is missing for some reason,
doesn't the apple VM store the runtime into rt.jar?
If not, we have a portability problem -- all other JVM
implementations I've looked at (among them IBM, Sun,
GNU) keep the base classes in rt.jar.


> And the "classes" directory is
> HUGE.

That must be the rt then. This means that we have to
add code which tries to detect the apple VM and rename
the "classes" directory into the standard name "rt".
Do you use a power or intel mac?


> It looks  
> like it has thousands of items (are these classes
> too)?

Yes, the directory contains java_lang_String.php and
the like.

> 1) What are all those other directories for when I

They're created for convenience.

You should not be printing to System.out, but instead returning a String
[untested]:

	public class HelloWorld {
	       public String sayHello() {
	              return "What up dog!";
	       }
	}

(I guess static methods also work; I can't remember now)

And then use this in PHP [untested, too]:

	// ...
	$x = new java("HelloWorld");
        printf("HelloWorld says '%s'<br/>",
               $x->sayHello());

[Php-java-bridge-users] Can't get simplest call using bridge to work - help

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

I am going crazy with this.  Any help would be greatly appreciated.

I just can't seem to understand how to communicate to java classes  
via PHP.  I know very little about Java, so am just trying to get the  
basics working before I go further with my project.  I'm sure this is  
ridiculously easy for you Java folks, but I am very confused - I must  
be going about this the wrong way:

I compiled a java class into a file called "HelloWorld.jar":

import java.util.*;
public class HelloWorld {
     public static void main (String args[]) {
         // insert code here...
         System.out.println("What up dog!");
     }
}

Then I created a PHP script to try and make a call to this using the  
PHP/Java bridge:

<?php
require_once('php_Java.php');
$dir = dirname($_SERVER['SCRIPT_FILENAME']);
java_require($dir."/HelloWorld.jar");

$x = new JavaClass("HelloWorld");
$y = new java_class("HelloWorld");
$z = new java("HelloWorld");
echo "=== CAST AS STRING ===<br/>";
echo (string)$x."<br/>";
echo (string)$y."<br/>";
echo (string)$z."<br/>";
echo "=== JAVA VALUES ===<br/>";
echo (java_values($x))."<br/>";
echo java_values($y)."<br/>";
echo (java_values($z))."<br/>";
echo "<p>-- END --";
?>

And when I fire this up in Safari to look at the results, I get:

=== CAST AS STRING ==
class HelloWorld
class HelloWorld
HelloWorld@aed5f9
=== JAVA VALUES ===
class HelloWorld
class HelloWorld
HelloWorld@aed5f9
-- END --

Why doesn't this thing print out my text.  What the heck am I doing  
wrong?  Any help appreciated.
