This is what I think .
First, let me explain the design model I implement (say, a DB query application)
1. Client sends (HTML) request to servlet asking for data from db. Client submit
userid & password.
2. Servlet conducts db access authentication
-> if login not allowed, feebacks login page (using rd.forward)
-> o.w, Servlet query db and generate a resultSet. Forward the resultset to a jsp file, say Format_RS.jsp
3. Format_RS.jsp formats the ResultSet to HTML Table (for example ) and feeback to client. ( I am experimenting using Format_RS.jsp just to generate a HTML string (eg HTML_out =" <Table> .. </Table>). After that, fowards the HTML string to another jsp Prsent_RS.jsp to display in client's browser)
(client -> servlet -> format_rs.jsp -> prsent_RS.jsp - client. Javabean only provides support functionalities)
I use java beans in servlet and jsp. Just like I use DLL functions in windows application. In the above model, servlets only take care of the business logic. Prsenting info to client is jsp's tasks.
Personally, I don't like to use javabeans in JSP to connect/query DB, since it is too messy to mix up HTML and jsp tags. As well, I don't use javebean to format resultset either. Simplily because I don't want to recompile the javabean source code to make a change in display. A text editor and a non java programmer and do the job.
I will highly appreciate someone points out my mistake and give me suggestion.
Sincerely
Jeff
