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

It is now in CVS. From the NEWS file:

Version 6.2.1

* $s = new java("java.lang.String", "hello");
  $b = $s->getBytes("ASCII");
  echo (string)$b;

  The (string) cast no longer converts the byte[] array to a
  java.lang.String using the encoding set with
  java_set_file_encoding() but returns the byte[] array as a
  PHP string without changing it.

  In previous versions one had to use java_cast($b, "string")
  to do a binary-safe conversion from byte[] to PHP string.


* To support both x64 and 386 windows dll's, the layout has been changed:

    WEB-INF --- cgi
                   |
                    --- x86-windows --- conf.d --- mysql.ini
[extension="php_mysql.dll"]
                   |               |
                   |                --- ext --- php_mysql.dll
                   |                --- php-cgi.exe <-- moved here
                   |
                   |
                   |
                    --- i386-linux --- conf.d --- mysql.ini
[extension="mysql.so"]
                                  |
                                   --- ext --- mysql.so
                                   --- php-cgi      <-- moved here

Won't fix, at least not in version 6.1.2.x

Fixed in CVS head. =>

Please use a servlet environment and use the methods from the
EngineFactory to access the ScriptEngine. The JavaBridge.war example
contains two examples: The
http://php-java-bridge.cvs.sourceforge.net/viewvc/*checkout*/php-java-bridge/php-java-bridge/examples/php%2Bjsp/jsp%2Bphp.jsp
show how to invoke methods in a (remote-) PHP application server.  The
other example http://php-java-bridge.cvs.sourceforge.net/viewvc/*checkout*/php-java-bridge/php-java-bridge/examples/php%2Bjsp/jsr223.jsp
shows how to execute a PHP script in the current application server.

What do you mean with this? When running in a servlet environment, you
can. Please see the example above.

I am sorry, but I cannot reproduce this problem using PHP/Java Bridge 6.1.2.1.

None. You could have used invokeFunction() as well.

Please ask the jetty maintainer for support. I am not going to support
this setup. You have the same libraries deployed at two locations,
within the web app and in the ext directory. Please either remove the
.jar files from the ext folder and try again. Or please use Tomcat,
which supports running our class files from a shared loader quite
well. I think jetty fails to pass the web app root directory to the
classes loaded from ext. But I am not going to debug this server,
especially since I know that it has some issues.

Hi,

[please excuse the delay]

$javaOutputStream = new java("java.io.ByteArrayOutputStream");
$exportManager->exportReportToPdfStream($jasperPrint, $javaOutputStream);

java_set_file_encoding("UTF-8");
print ((string)$javaOutputStream->toByteArray());

The (string) cast above invokes a byte[] => String conversion using
the file encoding UTF-8. Since cp1252 is the codepage used by java,
the result is invalid PDF.

Please either avoid the byte[] => String conversion by using
java_cast() or please use java_set_file_encoding("cp1252")

Please change your code to

[...]
print (java_cast($javaOutputStream->toByteArray(), "string"));


Whether or not the (string) cast should avoid the conversion and
behave like java_cast() is another question. I think it should. But
before we change it, we'll have to check carefully if this won't break
compatibility. -- The __toString() method for proxy objects appeared
in PHP 5.2.0, so I think a change won't break too much code.

Thank you very much for reporting this issue.

Hi,

I only attempted this so I could isolate the development of the Java to PHP side from my servlet.

> System.out.println(((Invocable)e).invokeMethod(e.get("php.java.bridge.PhpProcedure"),
> "f", new Object[]{}));
> ((Closeable)e).close();

Why could I not reference an actual script file?  

I tested the example you gave and it worked but the application hung.  Is that normal?

I don't follow: is there some other key I should have used?  I'm missing the point here. 


I'm now trying to get PHPJavaBridge deployed on my Jetty test server.  I've got the following setup:

Jetty
    lib
        ext
            JavaBridge.jar
            php-script.jar
            php-servlet.jar
            script-api.jar
    webapps
        JavaBridge.war
        java
            Java.inc

So when I try to browse http://localhost:8080/JavaBridge I get:

Cannot access /java within the current web directory.

I have tried putting the java directory under Jetty, under lib and under ext but I get the same error.  Any ideas?


Thanks again,

Bernard.
