I have problem in taking from the database the startdate and the finaldate of task to draw the chart
public IntervalCategoryDataset getCategoryDataset() {
conn = ConnectDB.ConnectDB();
TaskSeriesCollection dataset = new TaskSeriesCollection();
String sql = "SELECT `TITRE`, `DATE DEBUT Prévi`, `DATE FIN prévi` FROM `projet`;";
try {
pst = conn.prepareStatement(sql);
rs = pst.executeQuery(sql);
while (rs.next()) {
String a = rs.getString("TITRE");
Date StartDate = rs.getDate("DATE DEBUT Prévi");
Date EndDate = rs.getDate("DATE FIN prévi");
Names.add(a);
Dates.add(StartDate);
Dates.add(EndDate);
++count;
}
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e.getMessage());
}
int j = 0;
int k = 1;
TaskSeries series1 = new TaskSeries("Estimated Date");
for (int i = 0; i < count; i++) {
series1.add(new Task(Names.get(i),
Date.from(LocalDate.of(Dates.get(j).getYear(), Dates.get(j).getMonth(), Dates.get(j).getDay())
.atStartOfDay()
.toInstant(ZoneOffset.UTC)),
Date.from(LocalDate.of(Dates.get(k).getYear(), Dates.get(k).getMonth(), Dates.get(k).getDay())
.atStartOfDay()
.toInstant(ZoneOffset.UTC))));
}
dataset.add(series1);
return dataset;
}
I expect to have for every tasks its chart but I have the same chart for all the tasks.
You should apply a single loop, and in addition either use getObject(index, LocalDate.class) or - if your driver doesn't support the previous option - java.sql.Date.toLocalDate():
public IntervalCategoryDataset getCategoryDataset() {
conn = ConnectDB.ConnectDB();
TaskSeriesCollection dataset = new TaskSeriesCollection();
TaskSeries series1 = new TaskSeries("Estimated Date");
String sql = "SELECT `TITRE`, `DATE DEBUT Prévi`, `DATE FIN prévi` FROM `projet`;";
try {
pst = conn.prepareStatement(sql);
rs = pst.executeQuery(sql);
while (rs.next()) {
String name = rs.getString("TITRE");
LocalDate startDate = rs.getObject("DATE DEBUT Prévi", LocalDate.class);
LocalDate endDate = rs.getObject("DATE FIN prévi", LocalDate.class);
series1.add(new Task(name,
Date.from(startDate.atStartOfDay().toInstant(ZoneOffset.UTC)),
Date.from(endDate.atStartOfDay().toInstant(ZoneOffset.UTC)));
}
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e.getMessage());
}
dataset.add(series1);
return dataset;
}
You always get the same result because the j and k values are stacked in their default values and not incrementing along with the i counter in your for loop. Referring to the code am seeing, i advise you to get rid of the j and k counters, replace the j with i and the k with i+1.
Your for loop should be like the following:
for (int i =0; i<count; i++) {
series1.add(new Task(Names.get(i),
Date.from(LocalDate.of(Dates.get(i).getYear(), Dates.get(i).getMonth(),Dates.get(i).getDay()).atStartOfDay().toInstant(ZoneOffset.UTC)),
Date.from(LocalDate.of(Dates.get(i+1).getYear(),Dates.get(i+1).getMonth(),Dates.get(i+1).getDay()).atStartOfDay().toInstant(ZoneOffset.UTC))
)
);
}

a possible reason to this situation is, you are hitting mysql's max open connections error, because you are not closing connections in method CallItem_ListCreate. it seems mysql default max connection count is 151. you are openning 15 connections per hour and after 10 hour you will hit that mentiooned error.
p.s. : you should try running your code in debug mode (or using tools like visualvm, jstack) and view thread dumps as #saurav commented.
Quick questions...
I'm trying to make a Dynamic JTree but I can't get to put every database I have into one single node for each one. This is my code so far:
jTree2 = new javax.swing.JTree();
try {
String DSN = "jdbc:mysql://localhost";
String user = "root";
String password = "";
conexion = DriverManager.getConnection(DSN, user, password);
}
catch(Exception e) {
System.out.println("ERROR");
}
try {
sentencia = conexion.createStatement(
ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
}
catch(Exception e) {
System.out.println("ERROR2");
}
try {
String hi = "";
ResultSet rs1 = conexion.getMetaData().getCatalogs();
ResultSetMetaData rsmd = rs1.getMetaData();
int columnCount = rsmd.getColumnCount();
while (rs1.next()) {
for (int i = 1; i <= columnCount; i++ ) {
hi = hi + rs1.getString(i) + ", ";
}
//for
String sb = hi.substring(0, hi.length()-2);
jTree2.setModel(new FileSystemModel(new File(sb)));
}
}
catch(Exception ae) {
System.out.println("ERROR3");
}
jScrollPane3.setViewportView(jTree2);
And the result I get is this:
Every database is splitted by a "," but I want them to be on a single node for each one. Any help?
This should do it for you:
DefaultMutableTreeNode parent = new DefaultMutableTreeNode("Databases", true);
while (rs1.next()) {
for (int i = 1; i <= columnCount; i++) {
DefaultMutableTreeNode node = new DefaultMutableTreeNode(rs1.getString(i), true);
parent.add(node);
}
jTree2.setModel(new DefaultTreeModel(parent));
}
I'm adding data to a table model which in turn i will pass to the database.amoung some of the fields am adding is a date object as shown by the code below.
String ref = cboReferenceNumber.getSelectedItem().toString();
if(!txtAction.getText().equals("") ){
DefaultTableModel model = (DefaultTableModel)jTable1.getModel();
java.util.Date date = new java.util.Date();
String action = txtAction.getText();
String hierachyOfControl = (String)cboHierachyOfControl.getSelectedItem();
String responsiblePerson = (String)cboName.getSelectedItem();
java.util.Date dueDate = dcDueDate.getDate();
java.sql.Date sqlDueDate = new java.sql.Date(dueDate.getTime());
String status = txtStatus.getText();
Object[] newRow = {action,hierachyOfControl,responsiblePerson,sqlDueDate,status};
if(dcDueDate.getDate().getTime() <= date.getTime()){
JOptionPane.showMessageDialog(Corrective.this, "Due date can not be less or equal to today's date");}
else{
model.addRow(newRow);
}
}else{
JOptionPane.showMessageDialog(Corrective.this, "Please enter action required for"+" "+ref);
}
i then use the code below to add the created model to a database but the date column complains of the error message on my question header.
String sql = "insert into CorrectiveAction(ReferenceNumber,Action,Hierachy"+
",ResponsiblePerson,DuteDate,Status)values(?,?,?,?,?,?)";
String reference = cboReferenceNumber.getSelectedItem().toString();
TableModel tm = jTable1.getModel();
try {
Connection con = DbConnection.dbConnection();
PreparedStatement pst = con.prepareStatement(sql);
for(int tableRow = 0; tableRow < tm.getRowCount(); tableRow++){
for(int col = 0; col < tm.getColumnCount(); col++){
Object val = tm.getValueAt(tableRow, col);
pst.setObject(col+1, val);
pst.setString(6, reference);
}
pst.addBatch();
}
pst.executeBatch();
pst.executeBatch();
JOptionPane.showMessageDialog(this, "Record successfully saved..!");
}
catch (SQLException | HeadlessException | ClassNotFoundException e){
Logger.getLogger(Corrective.class.getName()).log(Level.SEVERE, null, e);

Kindly help me out
You need to find out whether MStorage calls rs.next() again, as you already used up all the results within another block:
while (rs.next())
{
MaufacuringDate = rs.getTimestamp("manufacturingdate");
}
I guess you have iterated over the record using Resultset object rs and now your rs cursor is at the end of the record/ or we can say it not pointing to any record.
Still your code below is using rs object which is exhausted and not pointing to any record/table row.
if (rs.getBigDecimal(11).signum() == 0) {
list.add(new MStorage(ctx, rs, trxName));
}
Possible solution :: Create a new statement, execute query and get the new ResultSet object whose cursor will be at the start of record (Note: Cursor at -1 (use .next())) and iterate over the record ad get the required result.
OR use some logic inside previous iteration over record and get the result there itself instead of iterating again .
I am trying to get date in my database that have format like this "dd/MM/yyyy" and compare them to get latest date..
I was surprised to find that it couldn't do the conversion implicitly or explicitly - but I don't even know how I would do this, as the Java API is still fairly new to me. Any suggestions? It seems like this should be an easy feat to accomplish.

Your loop resets i on every iteration. Move the declaration of i in your while loop. Or just use a for loop. Like,
for(int i = 0; rs.next(); i++) {
last_updatedDb = rs.getString("Last_updated");
System.out.println(last_updatedDb);
last_updatedArr[i] = last_updatedDb;
}
or something like,
int i = 0;
while(rs.next()){
// int i = 0;
last_updatedArr[i] = rs.getString("Last_updated");
System.out.println(last_updatedArr[i]);
i++;
}
SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
java.sql.Date date1,date2;
// reuse i from while loop...
for(i = 0; i < last_updatedArr.length; i++){
