Hi guys,

I'm currently working on a mobile phone application and need to save a file into the phone. However whenever I try using FileConnection, an exception will occur with the message "Application not authorized to access the restricted API". The FileConnection statement itself seems to be fine as I tried those from online examples, so I'm wondering what project settings I'll have to change to avoid this security issue. Please guide me with more details as I'm rather new to this, thanks!

Sincerely,
Ralph

Hi William, thanks for the link. However I tried the code on my phone (LG Secret) but the application hanged at the Java Powered screen. It worked when I tried compiling and running it on Java ME Platform SDK 3.0, Early Access though, you have any idea why?

It is probably down to the JME runtime. Check with LG if there is anything specific permissioning wise you need to do for the phone.

Hi

Following the code of my applet

Runtime rt = Runtime.getRuntime();
           Process proc = rt.exec("C:\\Program Files\\eSpeak\\command_line\\espeak.exe \"This is a text\"");
            int exitValue = proc.waitFor();

while the program is on the server

the applet run fine when i call the page on my machine

but when the web page is called on some other machine it gives access denied exception

i have set the permission on my jre but still no sol.

Applets are inheritly secured. You cannot execute process, perform I/O, database action with applets under nornal security manager settings. To do so, create your security manager and a policy file.

but will how will i tell the applet that the particular file is on the server file system not on the client.

and currently with the code above where does the applet look for the file under normal circumstances. Confused | :confused:

Further to the original answer.

An applet is sandboxed when running on the client. The runtime allows it to 'phone home', but AFAIK that is it. You cannot run an external process from an applet. Not at all. It's breaks the runtime. And then puppies die. Frown | :(

I was anticipating that so that is why I started this approach using a servlet

below is code of my servlet response

The process I Called give the audio wave file on console which i read and and now sending it as response but the audio is not hear able at the client I know I am making a mistake here but don't know where and i tried so many things

can you help

response.setContentType("audio/x-wav");
 PrintWriter out = response.getWriter();
 try
    {
       String line;

    Runtime rt = Runtime.getRuntime();
    Process proc = rt.exec("C:\\Program Files\\eSpeak\\command_line\\espeak.exe --stdout \"This is a text\"");

    AudioInputStream adstream= (AudioInputStream)proc.getInputStream();
    byte[] b= new byte[512];
    int bytes=0;

    while ( (bytes = adstream.read(b)) != -1 )
             {
             for(int i=0;i<bytes;i++)
                 {
                 out.print(b[i]);

                 }

The idea is coming, so no hiding behind the door:

An 'applet' is mini-applicatation that can be inside a webbrowser.
An 'agglet' is an agile applet that can reproduce itself and move around; but still sandboxed.
A 'servlet' is a small server-side applicatation.

Now, you've got a servlet creating, psssible, an audio stream.
The stream is returned to the applet and the applet does what exactly?

BTW I would be very VERY suprised if the code, as written, is actually getting the audio stream.

well let say it is because --stdout switch makes the program called to send the wav file on the console instead of writing it to file now it is on the console but the problem is to send it to ahead and their is some problem can you identify it?

"BTW I would be very VERY suprised if the code, as written, is actually getting the audio stream."

so if you have identified the problem can you tell me where it is Confused | :confused:

If that is really the case then it might work. What I would suggest is that you create the audio streams required on the server and feed them to the applet.
The applet can then play the audio; that I would need to google...

There are two ways to do so:
1. Use AJAX library
2. Post or submit data using javascript method.

Doubt on getPixel function

18-May-09 22:50

Questions for you:
0. Where is your program running?
1. How are you referencing the file?
2. Do you include the path?
