Connection Error

[rmarkert]

How can I catch an error from a Connection failed?

This is my code...

public void init(ServletConfig conf) throws ServletException {

super.init(conf);

try{
String driver = (String)getServletContext().getAttribute("db_driver"
String user = (String)getServletContext().getAttribute("db_adara_user"
String pwd = (String)getServletContext().getAttribute("db_adara_pwd"
String dbstring = (String)getServletContext().getAttribute("db_adara_string"


Class.forName(driver);
con = DriverManager.getConnection(dbstring,user,pwd);


}catch(Exception e) {
What can I do here?
I wanna give a message to user "Connection failed".
}
}



Thanks!

You can't give a message to a user in the init() method. This is called by the Web Container before the first request for the Servlet (usually upon booting the Web Container). Thus the best you can do is write to a log that the servlet could not be initialized and throw a javax.servlet.UnavailableException exception to let the container know that the Servlet failed to be initialized and should not be placed into service.
