Hibernate Data base connection lost - Java Discussion Boards

Think before creating anything.What is the purpose of creating a time picker in jsp instead of javascript? If there are no special purpose then go for javascript to save the implementation time.

Hi ...

I have tried to create Jsp Invoice but i have some problem i hope you can help me to do it ..

Blush | :O

This the javascript used to get price for the item

JavaScript

var xmlHttp
   var xmlHttp
   function showState(str){
       if (typeof XMLHttpRequest != "undefined"){
           xmlHttp= new XMLHttpRequest();
       }
       else if (window.ActiveXObject){
           xmlHttp= new ActiveXObject("Microsoft.XMLHTTP");
       }
       if (xmlHttp==null){
           alert("Browser does not support XMLHTTP Request")
           return;
       }
       var url="getprice.jsp";
       url +="?count="+encodeURI(str);
       xmlHttp.onreadystatechange = stateChange;
       xmlHttp.open("GET", url, true);
       xmlHttp.send(null);
   }

   function stateChange(){
       if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete"){
           document.getElementById("price").innerHTML=xmlHttp.responseText
       }
   }

Use the best guess

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.

Apart from this[^] and this[^], what exactly are you looking for?

Use the best guess

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:

VB

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");

modified 7-Mar-13 10:46am.

Ok, combo of hatred of M$ and Java here.... apparently when I installed Visual Studio Web edition or IIS it put a copy of SQL Server 2008 Express and Java was nice enough to grab that one vs the 2012 which Visual studio was... 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.

Knowledge exists, man only discovers it.

I have problem for creating invoice

like OpenERP invoice

any one can help me?

This is not a well framed question! We cannot work out what you are trying to do/ask from the post.

You need to elaborate and be specific on what are you trying to do and where are you stuck. Use the "Edit" link to edit your question and provide better information.

Hello,
I have a project that must use the artificial immune system as a method of classification.
I've asked my questions on other forums, but no large numbers of people who have used this method.
So please, someone he already used the AIS?
I depend on your support please for my project entitled:

"Application of the immune system for recognizing artificial
forms; the Arabic Script"

see this article Artificial Immune Algorithm in C#[^]

Bonjour,
j'ai un projet qui doit obligatoirement utiliser le système immunitaire artificiel comme méthode de classification.
j'ai déjà posé mes questions sur d'autres forums, mais il n'y a pas grand nombres de personnes qui ont utilisé ce procédé.
Donc svp, quelqu'un à t-il déjà utilisé l'AIS ?
je depend de vos aides s'il vous plaît pour réaliser mon projet intitulé:

" Application du système immunitaire artificiel pour la reconnaissance de
formes'' l’Écriture arabe "
et merci

This is an English speaking website/forum. could you please translate that to English so that every one could understand and answer to your query.

I'm not sure what you are asking here, but if you want someone to provide you with a ready made answer then you will be disappointed.

Je ne suis pas sûr de ce que vous demandez ici, mais si vous voulez quelqu'un pour vous donner une réponse toute faite, alors vous allez être déçu.

A bit of googling around came up with the following research paper..
