php-java-bridge-users Mailing List for PHP/Java Bridge (Page 2)

Hi,
   I already spent a long time finding out why java_require can't find my jar file in classpath.  I set Selinux to permissive to make sure that it's not because of selinux.  It seems that it can find the original java package correctly, e.g. java.io...
 But it can't find my custom jar files.  I tried to set the java.classpath in /etc/php.d/java.ini, but it still doesn't work.  I also tried to create a directory in /usr/share/java and put all my custom jar files there and then set the java.classpath, but it still doesn't work.  Don't know why.  I am using Eclipse with Trustudio to debug.  
 
 Many thanks.

Hi Victor,

the java bridge servlet logger does not provide a
timestamp; printing the log with a timestamp is the
servlet engine's job. 


>  Does the log
> support timestamp?  If so, how to turn it on?

For the standalone component the timestamp is on by
default. For the servlet engine it is off, but you can
provide your own logger, for example:

public class MyServlet extends PhpJavaServlet {

  public static class Logger extends
PhpJavaServlet.Logger {
    public String now() {
      // or something
      return String.valueOf(
         new java.sql.Timestamp(
           System.currentTimeMillis())):
    }
  }
  ...
}

Please see the API for details:
http://cvs.sourceforge.net/viewcvs.py/*checkout*/php-java-bridge/php-java-bridge/server/doc/php/java/servlet/PhpJavaServlet.Logger.html?rev=1.2

However, I think your servlet engine should have the
capability to print its log with a timestamp, it
should be an option in the server.xml.

Jost Boekemeier

 Hi,
   I am reading the php-java-bridge.log, but there is no timestamp.  I have no way to tell if the error is a past error or a current error.  Does the log support timestamp?  If so, how to turn it on?
 
 Many thanks.

Hi Shoan,

> Apache 2.0.54-r31 running on Gentoo.

there's an official php-java-bridge ebuild available
for gentoo.  I suggest to try that instead.

[...]

No idea. Probably some autoconf/automake/libtool/m4
issue (too old, dev. files missing etc.)

Please see the README for the list of supported
autoconf versions and the INSTALL document for more
information how to compile the bridge.

If you've followed the INSTALL instructions and still
get this problem please open a problem report (please
use
http://sourceforge.net/tracker/?func=add&group_id=117793&atid=679233)
and attach the configure.log to that ticket.

We'll look at this asap.

Please first deinstall the "ext/java" php_java.dll and
php_java.jar and remove all java options from your php
ini.

After that you can install the bridge as usual.


It is not possible to install the PHP/Java Bridge and
its successor, "ext/java" at the same time.

Hi Claus,

> [...] with PHP5.
[...]

> error: `_ISalpha' undeclared 

The php_java_snprintf code is not compiled when you
have php5.  If you get errors there, this may mean
that you compile against php4.

Anyway, the code should compile against php4 >=4.3.2
without problems, the _ISalpha macro is defined in
ctype.h.

Please follow the INSTALL description as close as
possible. If this doesn't work, please open a problem
report, please use

 Hi, I am trying the Bridge, but I got lost. 
  
  I am using EasyPHP 1.8. Now I could see this result
  
    Wed Nov 16 02:40:22 GMT 2005
    Now linking arrayToString.jar
    and calling ArrayToString->arrayToString(1,2,..,9)
    
    Fatal error:  Call to undefined function:  java_require() in c:\easyphp1-8\www\java-bridge\test.php
  
  it can find java.lang.System, but it can't find  arrayToString.jar.  I guess, this bridge should have some jar file  I should put to extension. but which one is ? I find EsayPHP has one  php_java.dll and php_java.jar defaultly.  
  
  Anybody has some experience in building this bridge in EasyPHP ?
  
  Thanks.

Hi,
  I have a java code like this: 

Car racecar = Car(0, 2);

How do I do this with php-java-bridge? 

If I do this:

$racecar = new Java("Car");  

then where do I put the parameter 0 and 2?

Many thanks.

Victor,

> Can setAttribute be used to save a java object in
> application scope?

  $ctx->put($key, $val)

can be used to store $val into the "application
store", yes. Please see the documentation for details
(php-java-bridge.sf.net).

This private "application store" is not shared with
.jsp or servlets. If you really need to access the
servlet context in version 2.x, please use the
following code:

public class MyControllerServlet extends
PhpJavaServlet {
 protected void service(HttpServletRequest req,
HttpServletResponse res) throws ServletException,
IOException {
  req.getSession().setAttribute("ServletContext",
getServletConfig().getServletContext());
 }
}

After that please change all references to
"PhpJavaServlet" to "MyControllerServlet" in the file
WEB-INF/web.xml.

You can access the servlet context as follows:
<?php
 dl('java.so');
 $servletCtx = java_session()->get("ServletContext");
 ...
 $servletCtx->setAttribute(...)
?>


> btw, where can I download 3.0? 

A preview version is in our CVS repository. But the
code is neither stable nor complete (some classes to
work with Java Server Faces are still missing).

Jost Boekemeier

Can setAttribute be used to save a java object in
application scope?  

btw, where can I download 3.0?  Is it a developmental
verion?  or is it a stable version?  Where are the
documentation of it?

I really need to use the application scope because I
am converting a jsp that uses application scope to
php.  

Thanks.

Hi Victor,

> scope, but how about application scope?

In PHP/Java Bridge 3.0 you can use 

java_context()->setAttribute(200, "test");

to store "test" into the application scope.


In version 2.x please use

  $ctx = java_session("myApplication");
  ...
  $ctx->destroy();

Hi Victor,

aliases or top-level environments are not available in
php.  You must use the full qualified name, e.g.:

$memoryBuffer=new java("java.io.BufferedInputStream");

Hi,
In JSP, it has application scope, session scope and
page scope. You can save a java object in the
application scope in JSP, and it will be there as long
as the web application is running. How do I do the
same thing in PHP, I know PHP can do session and page
scope, but how about application scope?

Many thanks.

It does contain that line. 

It seems my PHP uses the php.ini file when called via command line, as well.

Hi Michael,

> server (Apache2/PHP5), I get these messages a lot.
> PHP Notice:  php_mod_java(57): waiting for server

please make sure that the php.ini contains

extension=java.so


so that the extension is loaded only when apache
starts. If the above line is missing, the extension is
loaded for each request.

Hi Adam,

the java.lang.reflect.Array has the following factory
procedure:

 newInstance(Class componentType, int[] dimensions)

so that you can call:

$ar=$Array->newInstance(new java("java.lang.Object",
array(2,2,2,2,2,2));

to create an array with 6 dimensions.

$str=new java("java.lang.String", "hello");
$ar[0][1][0][1][0][1]=$str;

should work, at least in PHP5. (It might work in PHP4,
too, but then you have to use the array setter/getters
explicitly).


Regards,
Jost Boekemeier

Hi Jonathan,

I think this is a more general problem. My suggested
workaround doesn't even work for custom number types
which might not have an appropriate constructor. 
Representing a complex number as a php value isn't
possible anyway.

For version 3.0 we have the opportunity to change this
behaviour and remove auto-conversion of return values
completely. This would allow users to work with java
numbers or java strings in a natural way, for example:

$str = new java("java.lang.String", ${123}";
$str = $str->substring(2);
$str = $str->substring($str->length()-1);

If users want to convert a java object into a php
object they can always use the cast operator, for
example:

echo strchr((string)$str, "2");


Regards,
Jost Boekemeier
