Data Source Name

When using the JDBC-ODBC bridge driver in a statement such as this

  Connection conn = DriverManager.getConnection ("jdbc:odbc:orcl",user,passwd);

the word orcl in the "url" is referred to as a data source name.
Using this driver to access our Oracle database it is necessary that "orcl"
be defined as a data source name on the lab computer running your application.  
This may be accomlished by the following steps:

For the "Classic View" of Windows,
   Click on Start, then Settings, Control Panel, Administrative Tools, then
      Data Sources (ODBC); 
   A page will popup with the title "Microsoft ODBC Administrator;
   Click the ADD button and a pull-down menu will appear;
   Scroll down and choose "Microsoft ODBC for Oracle", and click "Finish";
   A pop-up window will appear with textboxes:
       Enter "orcl" (no quotes) in the box labeled Data Source Name and in
          the box labeled Server;
   Click the OK button and the Microsoft ODBC Administrator window will 
      reappear;
   Click OK again and a data source named orcl will have been defined.


Note: if you are using lynx on the llano server, substitute lynx for orcl.
