php-java-bridge-users Mailing List for PHP/Java Bridge

Hi,

> The bridge supports the JSR223 API. Which means that you could do the following (in pseudo
> code):

the following code works with the pure Java implementation (PHP/Java Bridge version 4):

<%

out.print("hello from JSP");

javax.script.ScriptEngineManager m = new javax.script.ScriptEngineManager ();
javax.script.ScriptEngine e = m.getEngineByName ("php");
javax.script.ScriptContext c = e.getContext ();

java.io.Writer w=new java.io.FilterWriter(out){public void close()throws
java.io.IOException{flush();}};

c.setWriter (w);

e.eval ("<?php echo java_inspect(java_context());?>");
e.eval ("<?php $w=java_context()->getWriter(); $w->write(\"hello from PHP\"); $w->close();?>");
e.eval ("<?php phpinfo(); ?>");

%> 


Note the FilterWriter above. It is needed because some versions close the output stream at the end
of the script.

Hi,

if I understand the jk_mount directive, you now forward all requests to the oracle application
server. 


> Is there any way I can include PHP code in JSP pages? 

The bridge supports the JSR223 API. Which means that you could do the following (in pseudo code):

<%
javax.script.ScriptEngineManager m = new javax.script.ScriptEngineManager();
javax.script.ScriptEngine e = m.getEngineByName("php");
e.setOutputStream (out);
e.eval ("<?php echo 1+2 ?>");
%>

However, isn't it possible to run PHP on the Apache web server and to use the PHP/Java Bridge
protocol to connect to the Java back end?

Jost Boekemeier

Hello again,

I downloaded the OAS 90MB download, installed it in a VM, followed your =
instructions and everything worked for me there as well. Unfortunately, =
it still didn't work in my application.

Anyway, after a lot more of trials and errors, and just as I was about =
to give up, it turns out that what I had to do to make it work in my =
application was to inlclude the following line in the mod_oc4j.conf file =
(included at the end of the Oracle/Apache httpd.conf):

<IfModule mod_oc4j.c>
...
Oc4jMount /JavaBridge home
Oc4jMount /JavaBridge/* home
</IfModule>

This made everything work (along with a change to the default J2EE port, =
which in my case was set differently).
Another difference I noticed in my case was that the protocol specified =
in the <web-site> directive was not "http", but "ajp13". I don't know if =
this made any difference.

Now, I only have one more question which is probably unrelated to the =
bridge, but nevertheless I would appreciate it if anyone could answer.
Is there any way I can include PHP code in JSP pages? I realize I =
probably cannot put <?php ?> tags in a JSP page and expect them to be =
parsed by PHP, but I tried including an external PHP file with <%@ =
include file "/myscript.php"%> and <jsp:include page=3D"/myscript.php"/> =
but it didn't work. I also tried <c:import url=3D"/myscript.php"/> but =
it somehow didn't seem to be interpreted by Java (I got it back =
literally in the html) which makes me think maybe my JSTL .jar file may =
be out of date or something.

Anyway, thanks again for going to great lengths to help Jost! :-)

Hi

> 07/11/23 16:07:21 Oracle Application Server Containers for J2EE 10g (9.0.4.0.0)

I have just tested the bridge against Oracle AS 9.0.4 and I could not reproduce these problems.


1. downloaded/extracted oracle web containers for java (the 90MB download)

2. copied home/config to home/config-new

3. changed home/config-new/application.xml so that it contains
     ...
    <web-module id="dms" path="../../home/applications/dms.war"/>
    <web-module id="JavaBridge" path="../../home/applications/JavaBridge.war"/>

4. changed home/config-new/http-web-site.xml so that it contains
   ...
   <web-app application="default" name="admin_web" root="/adminoc4j"/>
   <web-app application="default" name="JavaBridge" root="/JavaBridge"/>

5. changed the server port in home/config-new/http-web-site.xml to 8899:
   ...
  <web-site port="8899" 
   ...

6. Copied JavaBridge.war (from the version 3.2.1 j2ee download) to home/applications

7. Started the Oracle J2EE server so that it runs with the new configuration:

   java -jar '/home/jostb/Desktop/oc4j_extended.zip_FILES/j2ee/home/oc4j.jar' 
     -config '/home/jostb/Desktop/oc4j_extended.zip_FILES/j2ee/home/config-new/server.xml' 

8. http://localhost:8899/JavaBridge/test.php renders the test PHP page.


If the problem persists, please open a problem report and attach your configuration
at the end of the ticket (please use the following link
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233).

Hi,

I am not criticising OAS in general, but the way this particular
application was implemented, it is really a mess and with my limited
experience in Java/J2EE I can tell that a lot of things were not done
in a standard way.

Anyway, I tried to run the command as you suggested while all services
were running and I got the following error:

07/11/23 16:07:19 Auto-deploying file:/D:/oracle/oraMtier/j2ee/home/applications
/JavaBridge/ (New server version detected)...
07/11/23 16:07:20 Error starting HTTP-Server: Address already in use: JVM_Bind
07/11/23 16:07:21 Oracle Application Server Containers for J2EE 10g (9.0.4.0.0)
initialized

Do I need to shut down one of the services before I run this command?
I tried shutting down the HTTP server and then running the command
again, but got the same message minus the "Auto-deploying" stuff.

In both cases the url test.php does not work (404).

Thank you so much for replying, and I apologize if my questions seem a
little stupid, like I said, I don't have much experience in Java/J2EE.

Hi,

unfortunately for me this doesn't work. I'm pretty sure something's
messed up in the configuration of this particular OAS, because
although in the http-we-site.xml the port mentioned is 8888, there
appears to be no J2EE listener on that port.

I've also installed the JavaBridge.war as described in the
install.oracle file and I can see it is being expanded at runtime.
However, I cannot access the http://localhost:8888/JavaBridge/test.php
url.

Could it be that the whole site is only accessible through HTTPS?

Thanks for replying anyway :-)

I had the same problem running Tomcat and Apache - once you have the

Hi,

Thanks for the advice.  I finally got it working by using Tomcat as  
the back-end and compiling the java.so module using the --disable- 
backend option:

./configure --disable-backend --with-java=<JAVA_HOME>

Hi,

I'm working on an application that we took over from some other company, and
it's based on Oracle Application Server (on Windows 2003 Server). In
general, it's a mess in many ways, and on top of that we don't have a lot of
experience in Java/J2EE, so we're trying to combine PHP with the existing
codebase in order to leverage our PHP know-how.
So, to make a long story short, we've managed to successfully install the
PHP-Java Bridge v.3.2.1 with PHP 5.1.6 and the Oracle HTTP server (Apache
1.3) to the point where we can see the "java status" parameter as "running".
However, all our tests immediately return the following error:

Fatal error: php_mod_java(98): Call object is null: The connection to the
current back end doesn't exist anymore; probably the current back end has
been restarted w/o restarting the front end. in d:\www\javatest01.php on
line 8

We assume this has to do with connecting to the wrong host/port, but we are
at a loss in finding the right port. Attached is the report of ports in use
by the Oracle Application Server. The "running" status cannot be obtained
from 127.0.0.1:8888 or 127.0.0.1:7777. It usually works with ports 3701-4,
but then we always get the error above. Any ideas?

Thanks in advance

Hi,

the Linux C code is only supported on Debian or RedHat Linux. Please see the DEB and RPM
documentation for more information how to create a Debian or RedHat Linux package. (The C code
will compile on any operating system with the required autoconf installation, but we don't support
it)


Please use the pure Java implementation and the Java.inc instead. Please see the INSTALL.J2EE or
INSTALL.STANDALONE or INSTALL.J2SE documents and the README for details.

Hi,

I have a problem compiling the php-java bridge and keep getting the  
following:


configure: error: host_alias is not set. Make sure to run config.guess
Back-end configuration failed.
Please install the recommended autoconf, libtool and automake versions
or disable back-end configuration and use the pre-compiled J2EE back- 
end:

     ./configure --disable-backend --with-java=<JAVA_HOME>

configure: error: ./configure.gnu failed for server


Here is the output of config.guess (I am running Fedora Core 7):

x86_64-unknown-linux-gnu


Here is the command I am issuing:

phpize && ./configure --with-java=/usr/local/src/j2sdk1.4.2_15 && make


I have checked that I have all the correct versions of the tools  
including autoconf, automake and libtool.  I've tried the exact  
versions required and the latest versions but with no success.

I'd really appreciate any advice as I have been trying to sort out  
this problem for over a day now!

Many thanks,

I will respond to your message when I return.

Hi Jost,

Your last comment solved my problem! i found a lucene.jar in
'/srv/www/tomcat5/base/webapps/JavaBridge/WEB-INF/lib'. After i removed this
and reloaded tomcat it worked fine!

Thank you very, very much!

Hi,

> Even unpacked the jar

that might be part of the problem. You have multiple versions of your libraries in your
classpath(s) (e.g. web-inf/lib, web-inf/classes, /usr/share/java, $HOME/lib,
/usr/java/packages/lib/ext, the global $CLASSPATH, ...)

Debugging this is hard, especially if no common code repository exists (or no convention where to
store Java libraries).

Hi Jost,

Thank you for your explanation. I double checked that i use the right
library jar file, i load it with

$aJarFiles[] = _JAVA_PATH.'lucene'._DIR_SEP.'lucene-core-2.2.0.jar';
$aJarFiles[] =
_JAVA_PATH.'lucene'._DIR_SEP.'contrib'._DIR_SEP.'highlighter'._DIR_SEP.'
lucene-highlighter-2.2.0.jar';
$aJarFiles[] =
_JAVA_PATH.'lucene'._DIR_SEP.'contrib'._DIR_SEP.'spellchecker'._DIR_SEP.'
lucene-spellchecker-2.2.0.jar';
$aJarFiles[] =
_JAVA_PATH.'lucene'._DIR_SEP.'contrib'._DIR_SEP.'similarity'._DIR_SEP.'
lucene-similarity-2.2.0.jar';
$aJarFiles[] =
_JAVA_PATH.'lucene'._DIR_SEP.'contrib'._DIR_SEP.'analyzers'._DIR_SEP.'
lucene-analyzers-2.2.0.jar';

java_require(implode(";",$aJarFiles));

Which give me no errors so the files will be included like they should. Even
unpacked the jar, read through the compile .java file to find the method en
it is there but it isn't listed on the java_inspect function. How would that
be possible? The documentation says it is a public method.

You can use 

  echo java_inspect ($indexWriter);

to see the list of public methods exported by your version of the index writer.

Source files are irrelevant. It depends on which version of the library. 

If you use the dynamic class loader, the loader automatically uses the latest version of your
software (assuming that you name your java libraries appropriately, see the README for details).

I have the following problem, i updated my lucene java libraries to
lucene-core-2.2.0.jar. the API docs tell me i could do an update on the
indexwriter with a document. Everything works untill it reaches the update
document. it gives me :

Uncaught [[o:Exception]:"java.lang.Exception: Invoke failed:
[[o:IndexWriter]]->updateDocument([o:Term], [o:Document]). Cause:
java.lang.NoSuchMethodException: updateDocument([o:Term], [o:Document]).
Candidates: []

It says NoSuchMethodException but i'm pretty sure it is there (checked the
src files).

API Page:
http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/index/IndexWriter.html

snippit code:
$oLuceneAnalyzer = luceneAnalyzer::getStandardAnalyzer();
$oLuceneWriter = new Java('org.apache.lucene.index.IndexWriter',
'/srv/www/myindex',$oLuceneAnalyzer,false);

  for ($i = $this->nStart; $i < $this->nEnd; $i++)
  {
   $objDocument = $this->oLuceneHits->doc($i);
   $FieldStore = new JavaClass( 'org.apache.lucene.document.Field$Store' );
   $FieldIndex = new JavaClass( 'org.apache.lucene.document.Field$Index' );
   $FieldTermVector = new JavaClass( '
org.apache.lucene.document.Field$TermVector' );

   $objDocument->add(new Java('org.apache.lucene.document.Field',
'sectionPublished', '2:14', $FieldStore->YES, $FieldIndex->UN_TOKENIZED,
$FieldTermVector->YES ));

   $term = new java('org.apache.lucene.index.Term
','documentid',$this->oLuceneHits->doc($i)->get('documentid'));
   $oLuceneWriter->updateDocument($term,$objDocument);
  }
  $oLuceneWriter->close();


I tried to set logging in my php.ini settings but that doesn't seem to work,
it just won't write a log file, php.in settings:

Just copy Java.inc into the PHP "include_path".

The java.so (or php_java.dll) starts a Java process as a Apache- or IIS sub process.

Some development versions of PHP do not call mshutdown(), so that Apache waits for the 
sub process forever. The PHP developers usually detect these problems before each PHP release.
However, it is a good idea to start Java outside of the HTTP domain, anyway.

I've installed tomcat and using JavaBridge against it. It looks fine
now. But I don't like the idea of including remote file "Java.inc". Is
there some way to get things working without this?

I'm still not absolutely sure WHAT produces this problem. May be it's
problem with some patch used in Gentoo distribution. I'll try this on
pure vanilla apache + php system this weekend and let you know.

Hi,

I am sorry, but I could not reproduce this problem on RedHat Fedora or Ubuntu/Debian Linux.


[PHP mshutdown() procedure not called on a non-standard PHP installation]
> Gentoo linux
> PHP 5.2.4_p20070914-r2

If you use a non-standard PHP installation, please use the pure Java implementation and the
Java.inc instead. Or please report these problems to your OS vendor.

Hi,

I am sorry, but I could not reproduce this problem. Can you please attach a test case 
to the ticket #1824173
(http://sourceforge.net/tracker/index.php?func=detail&aid=1824173&group_id=117793&atid=679233)?

Yes, that's the expected behaviour when the same class is loaded twice by two different class
loaders.


> If "$clazz = new JavaClass("org.test.B");" was performed before
> "$bean->getA();" everything worked out fine

I don't think so. If you compare B@beanClassLoader with B@dynamicJavaBridgeClassLoader, you will
see that both classes are assignment incompatible.


> something was buggy in the dynamic classloading scheme.

There may be a bug in the dynamic class loader. But I fail to see it.

> addresses this, by checking findLoadedClass(name) before

The patch is incorrect. An attempt to load the same class twice must throw an exception. Otherwise
we will get ClassCastExceptions later on.

The problem, as I understand it, is, that you load the same class from two different locations.

Hi,

this sounds like a bug to me.

Presumably java_instanceof() has never been tested with the DynamicClassLoader. Please see
ticket#1824173
(=>http://sourceforge.net/tracker/index.php?func=detail&aid=1824173&group_id=117793&atid=679233)
for details.

I haven't received your attachment, but I think we are able to reproduce this problem.

Hi there!

Running (the otherwise excellent) php-java-bridge-4.1.8 I encountered a bug=
.

I had the following java-class structure

Class A
Class B extends A

>From php I referenced a remote EJB and called a method with the
following signature:

public A getA();

Where the method in fact returns an instance of  class B.

In php I then tried to figure out whether it was an instance of Class
A or B by using
java_instance_of:

$obj =3D $bean->getA();
$clazz =3D new JavaClass("org.test.B");
if ($clazz instanceof Java && java_instanceof($address, $clazz)){
  //...
} else {
 //...
}

However, this raised a LinkageException on the JVM, claiming that
Class B  already was loaded by the classloader.
If "$clazz =3D new JavaClass("org.test.B");" was performed before
"$bean->getA();" everything worked out fine, so I figured that
something was buggy in the dynamic classloading scheme.

I've attached a patch to the DynamicJavaBridgeClassLoader which
addresses this, by checking findLoadedClass(name) before
doLoadClass(name) but after verifying that it isn't in the cache.

/Sincerely
