Hi all!

I really need your help for this.  I installed the JDBC driver on my 
machine by copying the jar file in C:\Program Files\Apache Software 
Foundation\Tomcat 5.0\common\lib\pg73jdbc3.jar and set environment 
variable CLASSPATH to this path.  I  create a JSP page (code below).  
The first time I launched this JSP page, all was ok.  I don't use it 
since last week but when I try to launched it yesterday, I got an error 
to connecting database :

Error establishing the connection : 
Something unusual has occured to cause the driver to fail. 
Please report this exception: Exception: {0}

So, I don't think the error come from my code because it already work with the same code but I don't know what I do to cause this error now.  
Any help will be greatly appreciated.


-------code for jsp page---------
  /* Load the JDBC Driver */
  try {
  }catch(ClassNotFoundException cnfe) {
    out.println("<BR>Error loading driver " + cnfe + "<BR>");
  /* Define the connection URL */
  String dbName = "gec_test";
  String host = "localhost";
  String postgresqlUrl = "jdbc:postgresql://" + host + "/" + dbName;
  /* Establish the connection */
  String username = "bergeron.melanie";
  String password = "*****";
    Connection connection = DriverManager.getConnection(postgresqlUrl, 
username, password);
  }catch(SQLException e){
    out.println("<BR>Error establishing the connection : " + e + "<BR>");
