Solution
I have create a java-servlet project which uses sql server as a database. Underline project takes input from the ui and persist into database.
After inserting data into database, it will show up is records inserted successfully or not.
Change the DBConnectionUtils according to your database
String url = "jdbc:mysql://localhost:3306/";
String dbName = "root";
String driver = "com.mysql.jdbc.Driver";
This is the link for the project on github https://github.com/rosmahajan/java-servlet
Otherwise please post more information like any exception or error you are getting to investigate what is wrong with your code.
Hope this helps you !!
