RE: Source Evaluation?

[tmalin@xxxxxxxxxxxxxx]

Looking at them real quick, I would try to seperate my business logic from
my presentation. Seperate the connection and all HTML from the servlet. Use
JSP's for the presentation and a bean for the connection to the database. I
am trying to use the WebSphere connection pool for database access. I would
like someone elses opinion on connection pools (actual use).  You might
also try putting your try {  database connection  } catch block inside the
init() method after super.init(config) statement. init() is initilized one
time and you only need database connection one time.

private Statement statement = null;
private Connection conn = null;
private String URL = "jdbc:as400://web400;
private String userid = "";
private String password = "";

public void init( ServletConfig config )
      throws ServletException
{
  super.init( config );
try
    {
      Class.forName("com.ibm.as400.access.AS400JDBCDriver");
      con  = DriverManager.getConnection(URL, userid, password);
 }   catch (Exception e)  {
     e.printStackTrace();
     conn = null;
}

Well, the first two want em posted, so here we go.  :)
I'll attach them to this mail.

Thanks everyone!  Be honest and let me know what I'm doing wrong, and maybe
at least one thing I'm doing right.  :)

Here's how it works.  getfilename.html calls getFileName which builds HTML
and another form and calls runSQL.
