Cannot not run executable jar file after set content type for download

Dear all,

I have a jar file in server. I download it through ftp. And then I run the command : java -jar Hello.jar
The output is ok.

Then I try to make a download page (php) for user to download the executable jar file. However, after I download it. I run the same command. The output generate the following error :
================================================

Code:

Exception in thread "main" java.util.zip.ZipException: error in opening zip file

        at java.util.zip.ZipFile.open(Native Method)
        at java.util.zip.ZipFile.<init>(Unknown Source)
        at java.util.jar.JarFile.<init>(Unknown Source)
        at java.util.jar.JarFile.<init>(Unknown Source)

================================================

The download.php content
================================================

PHP Code:



    header("Cache-Control: ");// leave blank to avoid IE errors 
    header("Pragma: ");// leave blank to avoid IE errors 
//    header("Content-type: application/octet-stream"); 
    header("Content-type: application/java-archive"); 
    header("Content-Disposition: attachment; filename=\"".$fileName."\""); 
    header("Content-Disposition: inline; filename=$fileName"); 
    header("Content-Transfer-Encoding: binary");                                         
    header("Content-length:".(string)(filesize($fileString))); 
    sleep(1); 
    fpassthru($fdl); 
    header ("Connection: close");

================================================

so I guess the download.php cause the jar file error. but I cannot find the error. Would anyone know the solution?

Any person familiar with header.

thx help!!
