I am coding a CRUD app and want to fill my textbox input into the db, but I get an exception:
Here is my method:
public void create(Produkt p) {
if(p==null) {
log.error("Erstellen von null-Objekt in DB nicht möglich");
throw new IllegalArgumentException("Erstellen von null-Objekten in der DB nicht möglich");
}
if(p.getName().length()>30) {
log.error("Produktname zu lang!");
}
PreparedStatement ps=null;
try {
ps = hsqlmanager.getConnection().prepareStatement("INSERT INTO Produkt(name, kategorie, geloescht, haltbar, preis, altersfreigabe, bild) VALUES(?, ?, ?, ?, ?, ?, ?);");
} catch (SQLException e1) {
log.error("Es konnte keine Verbindung hergestellt werden im DAOProdukt!");
e1.printStackTrace();
}
try {
//TODO
ps.setString(1, p.getName());
ps.setString(2, p.getKategorie());
ps.setBoolean(3, p.isGeloescht());
ps.setBoolean(4, p.isHaltbar());
ps.setDouble(5, p.getPreis());
ps.setBoolean(6, p.isAltersfreigabe());
ps.setString(7, p.getBild());
System.out.println(p.getName() + p.getKategorie() + p.getPreis() + p.getBild() + p.isGeloescht() + p.isGeloescht() + p.isHaltbar());
ps.execute();//here I get the Exception
ps.close();
log.info("Produkt in DB erstellt.");
}
catch (SQLException e) {
log.error("createtes Produkt konnte nicht gespeicher werden - SQLFehler: " + e.toString());
e.printStackTrace();
}
}
Here is where I fill in the textbox:
String name=textBoxes.get(0).getText();
if(name.trim().isEmpty()) {
name="NO NAME ADDED!";
} else{
name = textBoxes.get(0).getText();
}
I guess it has to do with the name, beacause the exception says something like that:

So what does that mean? The exception points to the ps.execute(); but I am using the right type? Why?

I am getting this error while executing my java swing code.
How to solve this? I have found some questions similar to this but didn't got the required answers.
I am making a desktop application which will read tables from excel sheet and will update the table values in a database.
Here is the code snippet:
Main code from where I am reading and calling the database query
if (flag) {
int j=0;
String[] productArray= new String[2];
for (int i = 0; i < cr.getPhysicalNumberOfCells(); i++) {
String colKeyOrTabName = getCellValueAsString((cr
.getCell(firstCell + i)));
colKeyOrTabName=colKeyOrTabName.replaceAll(" ", "");
//colKeyOrTabName=colKeyOrTabName.replaceAll("[^a-zA-Z0-9-]", "");
productArray[j]=colKeyOrTabName;
j++;
//System.out.println(" "+ colKeyOrTabName);
}
if(!productArray[0].equalsIgnoreCase("code")){
DBConfig.insertCodes(productArray[0], productArray[1]);
}
/*Ends Here*/
rowNo++;
continue;
}
DB Code :
public class DBConfig {
private static BasicDataSource bds = null;
static{
try {
Class.forName("com.mysql.jdbc.Driver");
} catch (ClassNotFoundException e) {
// logger.error("Error - " + String.valueOf(e), e);
throw new RuntimeException(
"Error setting connection with SyntBots database");
}
bds = new BasicDataSource();
// set driver class name
bds.setDriverClassName("com.mysql.jdbc.Driver");
// Define Server URL
bds.setUrl(Config.get("config.db.url"));
// Define Username
bds.setUsername(Config.get("config.db.user"));
// Define Your Password
bds.setPassword(Config.get("config.db.password"));
}
public static void insertCodes(String code, String value) {
// TODO Auto-generated method stub
Connection con = null;
Statement stmt = null;
try {
// Connection conn = null;
con = bds.getConnection();
stmt = con.createStatement();
String sql = "insert into table(code,value) value('" + code+ "','"+ value+"')";
try{
stmt.executeUpdate(sql);
}
catch(SQLException e){
if(e.getErrorCode() == MYSQL_DUPLICATE_PK ){
System.out.println("Duplicate Entry"); }
}
// con.close();
} catch (Exception e) {
//logger.error("Ignore Error - " + String.valueOf(e), e);
} finally {
if (stmt != null) {
try {
stmt.close();
} catch (SQLException e) {
}
}
if (null != con) {
try {
con.close();
} catch (SQLException e) {
}
}
}
}
}
And here is the error(Console output) :

Update :
The Issue is fixed. It was of the case of missing JAR for MySQL driver.
But after that I am facing a new issue.
Have a look at the console output:

Well I have found the answer to my problem.
In my case it was related to the version of commons-pool2-2 jar file.
Instead of 2.4.2, I was using 2.0.
After changing the JAR to 2.4.2 it started working as expected.
Also I have used the mysql-connector-java-5.1.18 to resolve my previous issue.
NOTE : What I have found from the internet is that JAR compatibility is also need to fix the program.
I want to close my server when I press the stop button in my GUI. I use this code for the socket, which is listening if a client is connection to the serverSocket:
public void run() {
while (running) {
try {
if (serverSocketPassed) {
socket = serverSocket.accept();
scanner = new Scanner(socket.getInputStream());
stream = new PrintStream(socket.getOutputStream());
}
} catch (IOException e) {
System.out.println("err11");
e.printStackTrace();
}
}
}
And for the closing part the code looks this:
public void stop() {
try {
serverSocket.close();
running = false;
} catch (Exception e) {
System.out.println("Err");
e.printStackTrace();
}
scanner.close();
stream.close();
}
But when I call the stop function, before a client connected: I get an error.
This is the error:
err11

How can I properly close the server and it's components?
Instead of abruptly closing down the serversocket, close the stream.
Try this:
stream.close();
I try to make Test code about JTable input and refresh.
Insert and delete is working well,

Whenever you change your model vector directly, make sure to notify the container about this. You fail to do that in the following method:
private void delete(){
DefaultTableModel tmp = modelTest;
tmp.getDataVector().removeAllElements();
tableTest.repaint();
}
After the removeAllElements() you should call tmp.fireTableDataChanged(). Something like:
private void delete(){
DefaultTableModel tmp = modelTest;
tmp.getDataVector().removeAllElements();
tmp.fireTableDataChanged();
tableTest.repaint();
}
Reason: Changes directly to the Model's underlying data vector are not automatically propagated to the View. You are changing a Vector this way, not a Model. Changes to the Model are propagated to the View. Your calls to Model.addRow() inform the View that a row was added. Your Vector.removeAllElements() call is not informed to the View so after that call View and Model are out of sync (that is, if they weren't both empty before). The call to Model.fireTableDataChanged informs the View that the whole table data in the Model has changed. After this call they are in sync again. When Model and View are out of sync, you can expect ArrayOutOfBoundException's to occur e.g. during sorting.
I also had this problem recently - a NullPointerException caused by DefaultRowSorter.getViewToModelAsInts.
The problem for me is that I was trying to directly update the GUI when an exception was thrown in SwingWorker's doInBackground() method. I found the exact solution to my particular problem here. Maybe that will help you or at least point you in the right direction as I wouldn't be surprised if your problem was because you are trying to manipulate the GUI from the wrong thread.
I have a JTable connected to a database and a Delete button here is my code
Filling the table with data:
static class inventoryTableItems{
Object tempRow[];
public static DefaultTableModel itemTableModel;
inventoryTableItems() throws SQLException{
getItems();
}
public void getItems() throws SQLException{
try {
itemTableModel = new DefaultTableModel(MainFramePanels.inventory_Panels.data, MainFramePanels.inventory_Panels.Columns);
connectDB();
rows = stmtUpd.executeQuery("select c.*, q.Qty from catalogue=c inner join Quantity=q on c.SKU = q.SKU");
while(rows.next()){
tempRow = new Object[]{rows.getString(1),rows.getString(2),rows.getString(3),rows.getString(4),rows.getFloat(5),rows.getInt(6)};
itemTableModel.addRow(tempRow);
}
MainFramePanels.inventory_Panels.itemTable.setModel(itemTableModel);
MainFramePanels.mainFrame.pack();
MainFramePanels.mainFrame.revalidate();
}
catch (SQLException e) {
e.printStackTrace();
}
closeDB();
}
}
Here is the delete method code:
static class delOldItem{
delOldItem() throws SQLException{
delItem();
}
public static void delItem() throws SQLException{
String Oprt = "DELETE";
String Dscrpt = ("Delete TYPE("+tableItemType+") ITEM("+tableItemItem+") SKU("+tableItemSKU+") SIZE("+tableItemSize+") Thick("+tableItemThick+")");
try {
connectDB();
successPanel = new JPanel();
stmtUpd.executeUpdate("DELETE from catalogue where UPPER(SKU)=UPPER('"+tableItemSKU+"')");
getLog(Username,Oprt,Dscrpt,null);
new Log();
UIManager.put("OptionPane.okButtonText", "OK");
JOptionPane.showMessageDialog(successPanel,"SUCCESSFUL", "DELETE", JOptionPane.DEFAULT_OPTION);
new inventoryTableItems();
}
catch (SQLException e) {
e.printStackTrace();
}
closeDB();
}
}
When I delete a row it gives me an error.. what line is not correct? so that I will not have an error.
This is the error:

in delItem() function, move the position of following after closeDB() call.
new inventoryTableItems();
Hope it will help.
