Hi there,
I have a question.
In a servlet if we want to call a jar file we should import it.
Eg. import test.*;

if we want to use a class in that jar file, the way we call it is :

Try try = new Try();

and calling method in that class:


What if we want to initialize it. How to do this?Is the below code right?

Try try = new Try(1,2);

I have a servlet that will call a java application to execute.
Java application will produce an output which is wave file.
If I try to run the java file itself (stand-alone)and if it fails to produced an output an error message will appear at the dos windows.

The problem is how to transform that : System.out.println("error message")
to html ?

I use servlet to send input from jsp to my java program. Later, java program will creat a wav file as the ouput. i will embed the wav file in html page. the problem is, when i want to key in new input, it will go through the same process but when i want to play the wav file, i will listen to the previous wav file even in server the wav file have been overwrite with new wav output. When i clear user cache before key in new input, I will get the latest output. Is there anyway for the servlet to clear user cache before send new input to java application?

what i means from my previous reply is that even when i change attachment to inline, user still can save the file. what i want to do is it will not prompt the pop-up menu but it open it automatically for user. am i able to do that? if not, is there any other way or can i dumb the save button which mean that it just a button but if user click on it, nothing happen. or can i take out the save button

hi there....
a have a servlet where it will download a wav for user. a pop-up windows will appear and user can choose whether they want it to open or save.the coding :

public void download(HttpServletRequest req, HttpServletResponse resp)throws IOException {

PrintWriter out=resp.getWriter();

String filePath;

String fileNameNew="temp.wav";

resp.addHeader("Content-Disposition", "attachment; filename="+fileNameNew);
File uFile= new File("temp.wav");
int fSize=(int)uFile.length();
FileInputStream fis = new FileInputStream(uFile);
PrintWriter pw = resp.getWriter();
int c=-1;

while ((c = != -1){
// Close output and input resources.
}catch(Exception e){

despite pop-up windows, is there any way to do so that there will be no pop-up window but it will automaticly open the wav file using user's audio player.

the idea is i dont want to give privillage for user to save that file. they can only open it.
