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.
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 have two tables teams and games:
Drop table if exists game;
Drop table if exists team;
CREATE TABLE IF NOT EXISTS game (
yearGame int(11) NOT NULL,
winTeam int(11) NOT NULL,
lossTeam int(11) NOT NULL,
[Code] ....
I cant figure out how to load the values into the tables as only some of the fields are in the text and and the league field is in a seperate table. Here is my script so far
do {
JFileChooser chooser = new JFileChooser();
FileNameExtensionFilter filter = new FileNameExtensionFilter("Text/Java files", "txt", "java");
chooser.setFileFilter(filter);
int returnVal = chooser.showOpenDialog(null);

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 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 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).

I'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?

I have the following code which reads in data from a bluetooth transmitter, however the program is crashing upon read-in. The bluetooth connects to the device just fine, as indicated by the indicator LED on the transmitter. However during the read-in:
void beginListenForData()
is where the exception happens. Specifically, it is at the line
readBuffer[readBufferPosition++] = b;
However I don't know why it is crashing. My transmitter is sending 1 byte (0x02) at 9600 baud every 1 sec for testing purposes.
