Sevlet program for updating table

To do so, we just need to follow these steps: I've tried to document the following Java My SQL UPDATE example so you can see these steps.

To create the registration page in servlet, we can separate the database logic from the servlet.

But here, we are mixing the database logic in the servlet only for simplicity of the program.

For example, the if there is one, is used as the starting page.

With JDeveloper, you can define which page is to be the default run target for the application, that is, the page of the application that is displayed first, by defining it in the properties of the project.

In this chapter, you will see how you can modify the sample application and add functionality that allows users to edit, update, and delete data in Oracle Database.

Im having some little troubles with the UPDATE servlet.

Im trying to update my db but its just not happening. **NB: I'm just having trouble with the Update Servlet because i dont know how to get the modified datas from the JSP in order to send it to the DAO and then to update the DB.

Specifically, in this example, you'd probably already know the "id" for the user Fred, and when you go to update Fred's data, you would normally do it like this: ---- ------------ ----------- --------------------- ---------- ------------ | id | first_name | last_name | date_created | is_admin | num_points | ---- ------------ ----------- --------------------- ---------- ------------ | 2 | Fred | Flinstone | 2010-06-23 | 0 | 6000 | ---- ------------ ----------- --------------------- ---------- ------------ 1 row in set (0.00 sec) In "real world" Java database programs I almost always use the Spring JDBC libraries to access a database, but when you're first getting started, or working on small programs, I think it's important to see examples like this so you can understand how things work under the covers.
