1. Pleas indent your code and put it between <pre> tags for readability, thus
public void stop1()
{
this.player.close();
}
2. Give proper details of your problem.

when i play an mp3 file then if i want to pause that song for some time then i can't i can only play and stop the song in this code
|
|
|
|

Rather than just repeating your original post, it would be helpful if you followed my previous suggestions. It is extremely difficult to read your code from that unformatted listing, and I cannot find a method anywhere that handles a Pause command.

I'm getting two values for my salt
This is my code
private static String getSalt() throws NoSuchAlgorithmException, NoSuchProviderException
{
SecureRandom sr = SecureRandom.getInstance("SHA1PRNG");
byte[] salt = new byte[8192];
sr.nextBytes(salt);
return salt.toString();
}
and when I save it in my database
my code
PS.setString(1, User);
PS.setString(2, getSalt());
PS.executeUpdate();
System.out.println(" Salt :"+getSalt());
I get different value..why?
I'm salting String asdf
Database value [B@2fc396df
Printed value [B@5199c9ac
|
|
|
|
|
salt.toString();
That doesn't do what you think it does. It prints the object reference not the contents.
|
|
|
|
|
By the way, your function createSalt() creates a new salt every time you call it!
When you want to compare the original value and the database value, you hat to write the salt into a variable, then set it to your object, write to database, then retrieve from the database.

I showed you how to find information on reading CSV files, no doubt you can do the same for XML.

You don't use swing to read a file. Look at these links[^].

For output I should use swing.
and I know how to read .csv file, but my problem is with output.
how to get that output.

That question is impossible to answer in a forum like this. Go and find some swing tutorials and learn about what features are available to hlep you format your output.

I'm getting the right output but could not able to save the hash password into the database it's being stored as a Text.

Hello chdboy please check this line
PS.setString(1, User);
PS.setString(2, _Pass);
PS.executeUpdate();
you have provided normal text to user and password field
While you need to provide hex code in this line no 1 and 2
|
|
|
|
|
Thanks a lot ...now let's see if there is a problem in getting hex code back to the string when user enter details .
|
|
|
|
|
You shouldn't need to, that means anyone else can, and your system is not secure. Passwords should use one-way hashes so they can never be converted back to the original string. See Secure Password Authentication Explained Simply[^].

I am new to Java and Web Development. I need to build a Java server App, which has to interact with MySQL DB stored procedures and fetch rows and return to client.
1. Client can be from Http request from web browser
2. An Android app
3. Desktop app
4. and others
Now my question is; should the server App be
1.JSP
2.Servlet
3.WebService
Load balancing should be done for Server App, and server App is going to be 3-tire
Please advice the Pro/Cons in each case.

This question is far too broad for a technical forum such as this. You need to do your own research and study before deciding which technologies will be best to address your problem.
