How can we insert data through java servlet?
I can insert data to table by using JSP Scriptlet easily but I have a hard time with servlet.
public class UsertToDatabase() {
public boolean inserUser(String name, String email, String pwd) throws SQLException {
PreparedStatement pstmt = null;
boolean flag = false;
System.out.println("start");
openConn();
System.out.println("start_1");
if(conn == null) {
[code]....
I am positive that the above code function fine. The problem is whenever I call UserToDB() class inside the servlet, and I got this error: java.lang.ClassNotFoundException: org.postgresql.
Driver which mean that my conn (connection) is not connected to the database but I have ensure to do so by calling openConn() before start the transaction.
This is my servlet code:
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String username = request.getParameter("username");
String email = request.getParameter("email");
String password = request.getParameter("password");
List<String> errList = new ArrayList<String>();

I need getting detailed examples about how I can read/insert into database using JSF code for its different components. I am a beginner in JSF and I have the basics, however, I need the best source which it has useful, easy and detailed steps to understand the techniques for connecting to the DB and how to insert or read data from the database.
I tried to search, but I found the lessons are not useful or not described in details.

View Replies View RelatedI am new to java and attempting to write a method that will insert data from a cachedrowset into an MS Access 2010 database table. My goal is to use this code that will accept any kind of Oracle SQL table size with different kinds of values and insert them into MS Access.
After I ran the code I get an error message below. By process of elimination i was able to find the issue is coming from the method called "insertAccessTable" somewhere in the while loop area "while (CRS_insertAccess.next())", but I am stumped on how to resolve this issue.

I need to read in a file then create the tables and load in the data from the files to the database. I cant seem to figure out how to load the provided text file into the database.it contains lines like this
Boston Americans,AL,Pittsburgh Pirates
New York Giants,NL,Philadelphia Athletics
etc..
The first line in the field is the name of the team that won in 1903, and the last line is the name of the team that won in 2013. Note that the World Series was not played in 1904 or 1994, so those years are skipped in the file
The program should have a menu that has the following options.
NOTE: the data for choices to e) needs to come from running sql statements on the database tables created in choice a). Not from an ArrayList in memory.
a) Convert the baseball text file to a database table. Ask the user from a dialog box, for the location of the text file. This menu item should create the tables and load up the data.
b)Let the user input a team name, and list all of the years that they won the World Series
c)Let the user input a team name, and list the number of times they won the World Series
d)Let the user input a year, and you list the winner and loser for that year.
e)Add a new winner. The user should supply the winning team name, losing team name and year. Make certain that the year does not yet exist in the table and do not duplicate the team name(s) if they are already in the database tables.
f)Exit

I am developing my first Java application and the database I use is MySQL. I have created two separate buttons; one to insert new data into my database and the other to update the database when changes are made.
Each button is working perfectly, but I now want to combine both functions into just the save button. Thus, whether I am entering new data or modifying existing data, the save button should use an IF ELSE condition to decide whether to use the INSERT or UPDATE command.
My problem is, how do I write this IF ELSE statement? What should be the condition? For example;
IF(what? ){
String sql ="Insert into Table1 (classID,className,counselorID,startDate,endDate) values (?,?,?,?,?)";
}ELSE{
String sql2 = "update Table1 set classID = '"+value1+"',className='"+value2+"',counselorID='"+value3+"',startDate='"+value4+"',endDate='"+value5+"'
where classID = '"+value1+"'";
}
Creating a file upload servlet to accept a CSV and parse for insert into a database, however, whenever I click submit, it always seems to open a new tab/window. Below is the method I have that builds the upload form: (Using GWT 2.4)
private void buildUpload(){
LayoutContainer headerContainer = new LayoutContainer(new ColumnLayout());
headerContainer.setStyleAttribute("padding", "5px");
add(headerContainer);
NamedFrame hiddenFrame = new NamedFrame("uploadFrame");
final FormPanel form = new FormPanel(hiddenFrame);

Is there something I'm missing? or something I've added that makes it open a new tab/window?
I want to make a database and use it in my java program. I am thinking of using MS Access database, although I m not very sure, sine I will have to use this data later in the SQL database as part of C# program.
How to start to create and use MS database in java program.
I have seen in one tutorial that the steps are:
1. Install your database management system (DBMS) if needed
2.Install a JDBC driver from the vendor of your database
but I am not familiar with this. Any example, or is this above compulsory?
I am creating a portal using JSP and MySQL with eclipse IDE. I have a scenario where data is stored on draft table and is retrieved then stored on another table. I need the entry in the draft table to be deleted after the insertion. When I tried to run the code it redirects to success page but makes no impact on database(neither inserts not gets deleted).

my aim is to make a runnable jar. I've made a program using swings which uses MS Access database to fetch records. So, I've used an absolute path to refer to the database for connection. Now, I intend to distribute this runnable jar to other people as well. So I guess the best option would be to embed the MS Access database as well in the jar file. But I don't know how to do that. Where should I keep the database in my Project Explorer ? Should I use a relative path etc.
This is my code:-

import java.awt.*;
import java.awt.event.*;
import java.sql.*;
import java.util.Vector;

View Replies View RelatedI'm given a task to generate an API (a jar file) where the access of a certain database is provided through the API. basic functionality: Client sends a query through the API to server and the Server responds with data.Since its and API, do I have to implement the code or is it enough if i gave just interfaces? what are the OOP concepts to focus on when designing a good API.
View Replies View RelatedI'm trying to use in the constructor inserts from keyboard and then check whether any of the constructors fields remained empty. Let say my constructor is:
public SomeClass(String a, String b, String c)throws SomeClassException{
if (a == null || b == null || c == null) {throw new SomeClassException("Some message"); // here is the empty test
} //...
Thus I prepared method: insertConstruct() as follows:
public static String insertConstruct(){
String lettering = null;
Scanner sc = new Scanner(System.in);
lettering= sc.nextLine();
return lettering;
}
And during creating the new object in some main method I call:
// ...
ClassName obj1;
obj1 = new ClassName(insertConstruct(),insertConstruct(),insertConstruct());
//...
The problem is not with inserting data but with leaving the field empty. When I pass any field just with keyboards Enter, the empty test doesnt return me any message about it. While it works if I build object with the constructor like:
// ...
className obj1;
obj1 = new ClassName("word a",null,"word c");
//...
What might case this failure?
