Driver not found issue

[Joseph Smithern]

I need to create a site that will only have database updates around 1 or 2 times a day.
My Oracle driver is loaded in the Tomcat lib folder and I have connected to it before in other projects but cant connect to it using the below attempt.

For my connection I keep getting StackTrace error saying: jdbcDriver not found

Servlet:

private  DbManager dbManager;
public void init(ServletConfig config) throws ServletException
{
     super.init(config);
     dbManager = new DbManager();
     dbManager.setUrl(config.getInitParameter("url"));
     dbManager.setUser(config.getInitParameter("user"));
     dbManager.setPasswrd(config.getInitParameter("passwrd"));
     try
     {
        Class.forName(config.getInitParameter("jdbcDriver"));
      }
      catch (Exception ex)
      {
	System.out.println("Initialize connector string");
	ex.printStackTrace();
      }
}

DbManager class:

private String url = "";
private String user = "";
private String passwrd = "";
	
public void setUrl(String url)
{
	this.url = url;
}
	
public String getUrl()
{
	return url;
}
	
public void setUser(String user) 
{
	this.user = user;
   }
    
    public String getUser() 
    {
    	return user;
    }
    
    public void setPasswrd(String passwrd) 
    {
    	this.passwrd= passwrd;
    }
    
    public String getPasswrd() 
    {
    	return passwrd;
    }
    

    public Connection getConnection() 
    {
	    Connection conn = null;
	    try {
	      conn = DriverManager.getConnection(getUrl(), getUser(),getPasswrd());
	      }
	    catch (SQLException e) {
	      System.out.println("Could not connect to DB");
	      e.printStackTrace();
	      }
	    return conn;
    }
    

Db update class:

public class Update
{
     Connection conn = new DbManager().getConnection();
     ......

Please advise.

That's odd, because the only place that string occurs in the code you posted is here:

config.getInitParameter("jdbcDriver")

And the getInitParameter() method of ServletConfig won't throw any exceptions, it just returns null if there's no such parameter configured. Also, usually there's a lot more to a stack trace than that. It would help if you posted the rest of it. And if you could scan your code for the string "jdbcDriver" to see what else might be printing that string which you didn't post here.
