load JNLP file in PHP module

[amkreutz]

Hi developers,

I have a little problem.
In my PHP module I trigger a new PHP script like :

line 35: system(SCRIPT_PATH."/haragconvert.csh $pathOfBinXml $pathXml");

This script converts a Binary file to a normal XML file. At the end of this execution (script), a XML file is stored on the hard disk.

At the end of this PHP module, I must load a JNLP file.
I have written a JNLP class in PHP and this class writes dynamically a JNLP file and stores this on the hard disk too.

class:
$my_jnlp_class->writeJNLP ($fileName);

The aim of this project is, I wanne load this JNLP afterwards when the PHP script is read. So I wanne load that JNLP file developed in that PHP script.

I thaught it goes like this:

Like : header("Location: $fileName");

But then I become the error:

Cannot modify header information - headers already sent by (output started at /usr/local/JNLP.php:35)
see above line 35(script executed)

So what do I want:
Load the JNLP file after (in HTML like herf http://www.some.jnlp).
What's the statement (s) for loading a JNLP file and how dissepears th error Header already send.

Please help me guys.
Thank in advance

Yeah but in my case, is it while I have an output from the script:

system(path.haragconvert parameter parameter);

because I must write this statement in the PHP module and I want to
load that JNLP file.

How then must I load that jnlp file http://etc.jnlp

[rehfeld]

well im not sure what you mean by load the file

do you want to load the file into php so you can do something w/ it?

or do you just want to output the contents of that file to the browser?

do you want to redirect the browser to the location of the file?

maybe one of these is what you want

fopen()
file_get_contents()
readfile()
include()

[amkreutz]

well a simple example is:

in HTML a href http://www.server.file.jnlp

when the user then clicks on the link, the JNLP file will be loaded.

The created JNLP file on the hard disk (in my case), I wanne load.

Normally:
header("Location: $fileName");

but I got the error :
header already send etc...

because I must develop (see topic) the statement :

system(path.haragConvert. parameter parameter);

This statement gives me that error.

How to get that error away????
and load the JNLP file (http://www.someting.jnlp)

you didnt read the link i gave you? it tells you how.

in your case you prob want to use output buffering

$my_jnlp_class->add_sysproperty("adresXML", 
                         $pathXml);
$my_jnlp_class->add_sysproperty("adresIMG",   
                         $image_path);


$aux_functions = new auxiliary_functions();
$fileName = ".".$aux_functions->get_tmp_prefix
                              ().".jnlp";

$my_jnlp_class->writeJNLP ($fileName);

header("Location: $fileName");

?>

As you see in this PHP module I must write the system (haragr para para ) statement and what you said :outputbuffering is the solution.
BUT I can't do an inlude statement on the beginning of the PHP module, because the name of my JNLP file is a timestamp and is thus always another filename.

Maybe you know the problem more now or I don't get it.

thanx in advance Holland

where you have this:

require_once('globals/config.php');

change it to this:

ob_start();
require_once('globals/config.php');

thats it. it will fix the headers already sent error.

[amkreutz]

thank you rehfeld, this was the solution of my problem.

thanx thanx
