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

 am able to deploy an EAR into Jboss 4.0.4GA (ejb3 install) and can call an EJB3 Stateless Session.

I am however, having a little problem with logging - as soon as my EAR is deployed (or the original WAR) my console locks up.  I have managed to connect to the log4j output using Chainsaw so I know things are still working.  Why is my console and normal logging disappearing.

I sometimes get the following exception also - on a deployment (things still appear to work okay though)

p.s. Why is there such restrictions on posts to this forum - seems a little over censored in my opinion.  I have been writing software for many years, I admit to having no PHP experience, but I have had a few problems which I think had to do with the documentation not being particularly clear, are you afraid of a bit of constructive criticism?

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.

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.
