Connection con = DriverManager.getConnection(connectionUrl);

and no error is shown. However, If I changed the login username into a wrong one, error will be shown. what happened? I am using window 7 with sql server 2008.

Can you help me please? Thanks a lot.

Here is my connection:
Class.forName(“com.microsoft.sqlserver.jdbc.SQLServerDriver”);
String connectionUrl = “jdbc:sqlserver://TOSHIBA;databaseName=ogrenci;”;
Connection con = DriverManager.getConnection(connectionUrl);
jButton1.setText(“tamam”);
} catch (SQLException e) {
System.out.println(“SQL Exception: “+ e.toString());
} catch (ClassNotFoundException cE) {
System.out.println(“Class Not Found Exception: “+ cE.toString());
}

And here is the error:
SQL Exception: com.microsoft.sqlserver.jdbc.SQLServerException: Login failed for user ”.

My database has no user and password… I didn’t understand what’s the problem with this codes…

When i use this Url:
String connectionUrl = “jdbc:sqlserver://TOSHIBA;databaseName=ogrenci;integratedSecurity=true;”;

Then NetBeans gives me this error:
com.microsoft.sqlserver.jdbc.AuthenticationJNI
WARNING: Failed to load the sqljdbc_auth.dll
SQL Exception: com.microsoft.sqlserver.jdbc.SQLServerException: This driver is not configured for integrated authentication.

Could please help me urgently? Thanks in advance…

I have some issues on how to retrieve the data from the DB,
here are my specs:
Netbeans 5.5
MS SQL 2005+MS JDBC v4 driver.(successful connection with DB 4m Netbeans)

I have a table with following three fields:
fileType||fileExtension||fileHeader,
having values say,
JPEG_Image||JPG||FFD8,

now what i want is a query which will actually take the Jfilechooser’s input as the Header (read from file in hex) and then it SHOULD search in the 3 fields for the match of Header in the database, and then if found it should display it in messagebox or Jframe…

how do i use a variable, to:
1>store the value from the JFileChooser-header value to store in this variable
2>how do i construct a query so it will run and display the corresponding records as well.

I have the working code with me, however it is in plain java, no gui.

Can you please help.

Awaiting your reply
