Java DB Inserting Data Into Table
0
I am having trouble trying to insert data into a table in my database in netbeans, below is my code:
public class NewUser extends HttpServlet {
/**
* Processes requests for both HTTP <code>GET</code> and <code>POST</code>
* methods.
*
* @param request servlet request
* @param response servlet response
* @throws ServletException if a servlet-specific error occurs
* @throws IOException if an I/O error occurs
*/
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=UTF-8");
HttpSession session = request.getSession(false);
String query = new String[5];
query[0] = (String)request.getParameter("username");
query[1] = (String)request.getParameter("password");
query[2] = (String)request.getParameter("confPassword");
query[3] = (String)request.getParameter("name");
query[4] = (String)request.getParameter("address");
Jdbc jdbc = (Jdbc)session.getAttribute("dbbean");
if (jdbc == null)
request.getRequestDispatcher("/WEB-INF/conErr.jsp").forward(request, response);
else {
jdbc.insert(query);
request.setAttribute("message", query[0]+" has been registered successfully!");
}
This is in a class "NewUser.java". The insert method is in a class "jdbc" and is as follows:
public void insert(String str){
PreparedStatement ps = null;
try {
ps = connection.prepareStatement("INSERT INTO CUSTOMER VALUES (?,?,?,?)",PreparedStatement.RETURN_GENERATED_KEYS);
ps.setString(1, str[0].trim());
ps.setString(2, str[1]);
ps.setString(3, str[3]);
ps.setString(4, str[4]);
ps.executeUpdate();
ps.close();
System.out.println("1 row added.");
} catch (SQLException ex) {
Logger.getLogger(Jdbc.class.getName()).log(Level.SEVERE, null, ex);
}
}
The "CUSTOMER" table looks as follows:
# | Username | Password | Name | Address | ID
('ID' is the primary key which is auto incremented)
The JSP where the user inputs the information is as follows:
<%@page import="model.Jdbc"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>User</title>
</head>
<body>
<h2>User's details:</h2>
<%! int i = 0;
String str = "Register";
String url = "NewUser.do";
%>
<%
if ((String) request.getAttribute("msg") == "del") {
str = "Delete";
url = "Delete.do";
}
else
{
str = "Register";
url = "NewUser.do";
}
%>
<form method="POST" action="<%=url%>">
<table>
<tr>
<th></th>
<th>Please provide your following details</th>
</tr>
<tr>
<td>Username:</td>
<td><input type="text" name="username"/></td>
</tr>
<tr>
<td>Password:</td>
<td><input type="password" name="password"/></td>

<tr>

</tr>
<tr>
<td>Address:</td>
<td><input type="text" name="address"/></td>
</tr>
<tr>
<td> <input type="submit" value="<%=str%>"/></td>
</tr>
</table>
</form>
<%
if (i++ > 0 && request.getAttribute("message") != null) {
out.println(request.getAttribute("message"));
i--;
}
%>
</br>
<jsp:include page="foot.jsp"/>
</body>
</html>
The SQL statement used to create the database:
CREATE TABLE Customer (
username varchar(20),
password varchar(20),
name varchar(20),
address varchar(60),
id INT primary key GENERATED ALWAYS AS IDENTITY (START WITH 1, INCREMENT BY 1)
);
The code doesn't throw any errors however, when I check the database to see if the data has been added it never gets added and I cannot figure out why (I think it's something to do with the "insert" method?). I have looked around for solutions however, I still get the same outcome and could really use some help.
Cheers,

For Oracle you need to specify column for auto generated columns:
ps = connection.prepareStatement("INSERT INTO CUSTOMER VALUES (?,?,?,?)", new String{"ID"})
For ID column

You forgot to replace prepareStatement.return.. to Statement.return..ps = connection.prepareStatement("INSERT INTO CUSTOMER VALUES (?,?,?,?)",Statement.RETURN_GENERATED_KEYS,new String{"ID"});

Are you sure all the columns in the Customer table are varchars or some are int too.
– Himanshu Ahuja
Nov 18 '18 at 14:25
The only one that is an int is the primary key "ID", I will edit my post to show the SQL statement I executed to create the table, hopefully that will help!

Unfortunately this didn't work either, could it possibly be due to the 'CUSTOMER' table itself? Each column is just of type 'VARCHAR' other than 'ID' which is an integer

Unfortunately that didn't work either, I really appreciate the help! The actual data that is being put into the table is inputted in a jsp file, i'm not sure if that'll help but i'll edit my post to include the jsp

For Oracle you need to specify column for auto generated columns:
ps = connection.prepareStatement("INSERT INTO CUSTOMER VALUES (?,?,?,?)", new String{"ID"})
For ID column

You forgot to replace prepareStatement.return.. to Statement.return..ps = connection.prepareStatement("INSERT INTO CUSTOMER VALUES (?,?,?,?)",Statement.RETURN_GENERATED_KEYS,new String{"ID"});

Are you sure all the columns in the Customer table are varchars or some are int too.
– Himanshu Ahuja
Nov 18 '18 at 14:25
The only one that is an int is the primary key "ID", I will edit my post to show the SQL statement I executed to create the table, hopefully that will help!
