I'm trying to find a good source of information on how to playback audio samples in java. Preferably with source code examples that I could learn from.

The sample durations are too short to be kept in individual files because of the time taken to load them.

So the idea is to playback samples that are equally spaced within one monolithic audio file.

It doesn't seem like an impossible task, but finding information on java audio (all in one article) has been difficult.

Q. Hey man! have you sorted out the finite soup machine?

A. Why yes, it's celery or tomato.

jtds connection problem.... SQL Server 2012 Express

This is my first Java database application so I'm sure I'm missing something. This is the code I have...

Java

import java.sql.*;

public class ClsConn {
    private Connection conn;
    
    public Connection openConn() {
        try {
            System.out.println("Trying the connection now...");
            //Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
            Class.forName("net.sourceforge.jtds.jdbc.Driver");
            //conn = DriverManager.getConnection("jdbc:odbc:IntranetSql");
            conn = java.sql.DriverManager.getConnection("jdbc:jtds:sqlserver://localhost:1433;databaseName=Intranet;user=sa;password=passwrd");
            System.out.println("DSN Connection ok.");
        } catch (Exception e) {
            System.out.println("DSN Exception: " + e.getMessage());
            e.printStackTrace();
        }
        return conn;
    }
}

This was originally using a DSN, but that didn't seem to work (I was getting some interesting behavior) so I've gone to what you see there. I'm getting this error message: Cannot open database "Intranet" requested by the login. The login failed.

For reference on the same server for my asp pages I have the following which is working:

Public Function OpenConnection() As Boolean
       Dim connString As String
       cnn = New SqlConnection
       connString = "server=localhost; uid=sa; pwd=password; database=intranet"
       Try
           cnn.ConnectionString = connString
           cnn.Open()
           Return True
       Catch ex As SqlException
           GlobalClasses.Client_Alert(ex.Message)
           Return False
       End Try

   End Function

I have opened up 1433 on the server so I have no idea what's going on... Any ideas would be greatly appreciated...

--Update 1--
For "fun" I just changed the Database to "Master" and the gosh darn thing "works"... well my query fails because the table it's looking for isn't in Master but the connection is working. I really need to start drinking or something. So it appears that everything is working for for some reason I can't see the database???

--Update 2--
Ok so I change my query figured that would be a good idea right? Nah... So I put in "use Intranet SELECT...." and get "Exception: Database 'Intranet' does not exist. Make sure that the name is entered correctly.". So I did what any good frustrated developer would do and opened up the mgmt studio for SQL Server and went to master and ran the same exact query with the "use..." (yes I cut and pasted it in just to be 100% sure) and imagine that it works. Yet my Java application is still saying it doesn't exist.
I am trying to figure this out not just waiting for an answer... Big Grin | :-D

--Update 3--
Connection string is now:
conn = java.sql.DriverManager.getConnection("jdbc:jtds:sqlserver://localhost:1433/master;user=sa;password=passwrd");

Stopped the service for 2008 and now it's working... I'm going to go grab a drink now.

Hello,

try specifying the instance parameter in connection string. Following text is extracted from the JTDS FAQ.

SQL Server can run multiple so-called "named instances" (i.e. different server instances, running on different TCP ports) on the same machine. When using Microsoft tools, selecting one of these instances is made by using "<host_name>\<instance_name>" instead of the usual "<host_name>". With jTDS you will have to split the two and use the instance name as a property.

Regards,

Prasad P. Khandekar

Hey guys & gals.

I'm just asking a quick question about my end of year college project.

I've written an Android application which scans student ID's, gets the information from the barcode, sends that to a server which shows on screen via WiFi.

Now currently I have it set so when it receives the info it saves to a txt file.

I allready have an excel file with details in it e.g Student Number, days present, Submission.

Is it possible for me to use a button press on the Server GUI that will take the string e.g "ABC12345" from the txt file and run a check against "ABC12345" in the Excel file containing the students info? which will then do checks using "fuzzy" logic, e.g if they missed 4 days out of 20 they're OK and if they miss 15 out of 20 they're in trouble?

If it is possible to do, could you give me some guidance on how to go about checking the txt file string against the Excel and any tutorials I can read up on? Smile | :)
