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...

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

Hi...

I am going to convert my codings Visual c++ to java...
I just want to know ..
Do we have any function in java which equivalent to [ GetPixe() in Visual C++ ] ...

If you've got a question post it and post it once. Using multiple forums will not help. Changing your displayed name will not help.

Everytime you double post, a sweet little puppy dies! Looking at your postings here and in the c/c++ forum, you don't like puppies!

Now, go to the corner and sing the very sorry song.

Manipulating other Applications

15-May-09 21:29

Hi..Sakthi here..

First i would like to thank all Expert's for your good response..
Here i have given the question with one Ex:
My question Thumbs Up | :thumbsup:

is the check whether the entered input text is meaningful or not...For this we need to compare the given input with english dictionary,if we have found exact word then we can accept it .other wise reject rhe word..We are checking in terms of spelling ..

Class -------- > Text ( Selected )

Klass -------- > Spelling mistake ( Rejected )

------------------------------------------------------------

Like that we need to implement the english dictionary in java
Does we have any separate built in class for this process..

Waiting for good response

Thanks in advane ..

Hi, I am trying to write a Java Applet to manipulate other applications. For example,execute the application, then make the mouse to click any where on the application and record the Mouse clicks/verify to replay it at later time. Anyone knows how to do this in Java. I know how to record the mouse clicks in Applet, but how would you do this in another application?

Thanks in advance. Any help is greatly appreciated.
