Image not visible in JLabel with mouse click in JTable

I'm making a small application for a school project. Inserting photos into SQL database is fine, I rename the photos in a JTable and can also open blob photos in SQL editor. It is not possible to make the photos visible on a JLabel.
Can someone help me on this?
The intention is to get a preview of the information that has been entered at a mouse click. the application is an image bank where you can enter different healthcare devices.
Code JTable
DefaultTableModel model = (DefaultTableModel) tableDom.getModel();
try {
Class.forName("com.mysql.jdbc.Driver"); //database connectie maken
try (Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mybrains?
allowMultiQueries=true&serverTimezone=America/Winnipeg&dummyparam=", "", "")) {
String sql = "Select * from Telefonie ";
PreparedStatement pstmt = conn.prepareStatement(sql);
ResultSet rs = pstmt.executeQuery(sql);
model.setRowCount(0);
while (rs.next()) {
int id = rs.getInt("ID");
String naam = rs.getString("naam"); // naam is een kollom in de database
String model_type = rs.getString("Model_Type");
String functionaliteit = rs.getString("Functionaliteit");
String troubleshoot = rs.getString("Troubleshoot");
String oplossing = rs.getString("Oplossing");

//voorbeeldfoto.setIcon(foto());
model.addRow(new Object[]{id, naam, model_type, functionaliteit, troubleshoot,
oplossing, voorbeeld, fotos});
}
}
} catch (ClassNotFoundException | SQLException e) {

Fetching image from database and directly read it into panel

I am fetching a image from database and directly read it into panel using Imageio.read method with Bufferimage reference variable but it gives me error javax.imageio.IIOException: Can't read input file! I don't understand why it gives me error.
My database code:
public class ValidateClass {
public static byte[] validateImageAndEmpId(Connection con, String empId) {
byte[] imagedata = null;
try {
PreparedStatement ps = con.prepareStatement("select image from fingerprint where empId=?");
ps.setString(1, empId);
ResultSet rs = ps.executeQuery();
if (rs.next()) {
Blob blob = rs.getBlob("image");
imagedata = blob.getBytes(1, (int) blob.length());
System.out.println("Length" + imagedata);
System.out.println("testlen" + imagedata.length);
}
} catch (Exception e) {
e.printStackTrace();
}
return imagedata;
}
}
Code where I call this method:
public CEntityForm() {
jButtonStep1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
jButtonStep3_actionPerformed(e);
}
});
/*jButtonStep1 for 1 to 1 match fingerprint matching which is not in use */
jtool.add(jButtonStep1);
try {
// Taking picture1
//Set picture new
m_bimage1 = ImageIO.read(new File(new java.io.File("").getAbsolutePath() + "\\L1Right.Jpeg"));
m_panel1.setBufferedImage(m_bimage1);
//Send image for skeletinization
m_finger1.setFingerPrintImage(m_bimage1);
finger1 = m_finger1.getFingerPrintTemplate();
//See what skeletinized image looks like
m_bimage1 = m_finger1.getFingerPrintImageDetail();
m_panel1.setBufferedImage(m_bimage1);
//fingerprint matching details of finger 1 in number format so commented jtextfield2
// jTextField1.setText(m_finger1.ConvertFingerPrintTemplateDoubleToString(finger1));
/*end of picture 1 details*/
// Taking picture2
//Set picture new
Connection con = Conn.getConnection();
byte[] bytearry = ValidateClass.validateImageAndEmpId(con, $emp_Id);
// System.out.println("Input="+input);
m_bimage2 = ImageIO.read(new ByteArrayInputStream(bytearry));
// m_bimage2 = ImageIO.read(new File(new java.io.File("").getAbsolutePath() + "\\L1Right_Copy.Jpeg"));
m_panel2.setBufferedImage(m_bimage2);

Main Method
public class Testmain {

Output:

The exception seems to come from your other call to ImageIO.read(); the first one in the constructor. There you're passing a file that presumably doesn't exist.

JDBC JTable image

I have an item database (jdbc) the functionality is: insert, delete, and update using GUI JTable, all work good but I need to display the image in the JTable but I couldn't :(
If you could help me in that, here's the code for the main functionality:
fill Table method:
try{
connection= DriverManager.getConnection(url, usr, pas);
statement = connection.createStatement();
resultSet = statement.executeQuery("select * from item");
itemTable.setModel(DbUtils.resultSetToTableModel(resultSet));
} catch(SQLException ex){
JOptionPane.showMessageDialog(null, ex);}
add method:
try{
PreparedStatement insert =connection.prepareStatement("INSERT INTO items"
+"(name, price, image, ID)"
+"VALUES(?,?,?,?)");
insert.setString(1, nameTextField.getText());
insert.setDouble(2, Double.parseDouble(priceTextField.getText()));
insert.setByte(3, image);
insert.setInt(4, Integer.parseInt(IDTextField.getText()));
int row = insert.executeUpdate();
fillTable();
}catch (SQLException ex){
JOptionPane.showMessageDialog(null,ex);}
update method:
try{
PreparedStatement update =connection.prepareStatement("update item set "
+ "name=? , price=?, image=? where id=?""
+"VALUES(?,?,?,?)");
update.setString(1, nameTextField.getText());
update.setDouble(2, Double.parseDouble(priceTextField.getText()));
update.setByte(3, image);
update.setInt(4, Integer.parseInt(IDTextField.getText()));
int row = update.executeUpdate();
fillTable();
}catch (SQLException ex){
JOptionPane.showMessageDialog(null,ex);}
delete method:
try{
Statement delete = connection.createStatement();
delete.executeUpdate("delete from item where id="+IDTextField.getText());
priceTextField.setText("");
nameTextField.setText("");
idTextField.setText("");
fillTable();
}catch (SQLException ex){
JOptionPane.showMessageDialog(null,ex);}
A button event to choose image from JFileChooser:
String imagePath = null;
JFileChooser file;
private void ChooseImageButtonActionPerformed(java.awt.event.ActionEvent evt){
int result = file.showSaveDialog(null);
if(result == JFileChooser.APPROVE_OPTION){
File selectedFile = file.getSelectedFile();
String path = selectedFile.getAbsolutePath();
imagePath = path;
}
}

The important methods are fillTable() and add().
fillTable method could be like this:
//you need a TableModel, let´s call it model and let´s call your JTable myJTable
TableModel model = (javax.swing.table.DefaultTableModel) myJTable.getModel();
myJTable.setModel(model);
//try to add results
try {
connection = DriverManager.getConnection(url, usr, pas);
statement = connection.createStatement();
resultSet = statement.executeQuery("select * from item");
while (resultSet.next()) {
//after your query, get the Image
Blob blob = resultSet.getBlob(3);//column 3
byte[] data = blob.getBytes(1, (int) blob.length());
BufferedImage img = null;
img = ImageIO.read(new ByteArrayInputStream(data));
Icon imgToTable = imageToIcon(img);//use the method below
//add row to your table (throught the model)
model.addRow(new Object[]{resultSet.getObject(1).toString(), resultSet.getObject(2).toString(), imgToTable,resultSet.getObject(4).toString()});
//itemTable.setModel(DbUtils.resultSetToTableModel(resultSet));
}
resultSet.close();
} catch (SQLException ex) {
JOptionPane.showMessageDialog(null, ex);
}
Add method could be like this:
try{
PreparedStatement insert =connection.prepareStatement("INSERT INTO items"
+"(name, price, image, ID)"
+"VALUES(?,?,?,?)");
insert.setString(1, nameTextField.getText());
insert.setDouble(2, Double.parseDouble(priceTextField.getText()));
//i recommend to use something like this to configure you image
file = new File(imagePath);
fis = new FileInputStream(file);
if (null == fis) {
fis = new FileInputStream(imagePath);
}
//configure image
insert.setBinaryStream(3, fis);
// insert.setByte(3, image);
insert.setInt(4, Integer.parseInt(IDTextField.getText()));
int row = insert.executeUpdate();
fillTable();
}catch (SQLException ex){
JOptionPane.showMessageDialog(null,ex);}
And use this to convert from Image to Icon (to put it in a Table Cell):
//from Image a Icon
public Icon imageToIcon(Image image) {
ImageIcon imgIcon = new ImageIcon(image);
Icon iconReturn = (Icon) imgIcon;
return iconReturn;
}
If in your database you are not using blob let me know.

JAVA 1.7 and Mysql 5.7 connection

I have Java jdk1.7xxx installed and a MySQL database v5.7 too.
My database is named "mydb".
I access it from the mysql console.
However when I try to access it from my java program it makes an error "source of data unknown, or pilot name not specified". So I am missing some pilot/extra file I guess. But I did import java.sql.* at the beginning of my program..

Adding the jar:

I think that in String url = "jdbc:mysql://localhost/mydb";
you forgot to write the port number.
try String url ="jdbc:mysql://127.0.0.1:3306/mydb";
UPDATE
Ok, just try this code and run it from Eclipse and not from cmd.
Also you use executeUpdate for INSERT. For SELECT you use executeQuery.
//Execute when button is pressed
System.out.println("You clicked the button SAVE");
String url = "jdbc:mysql://127.0.0.1:3306/mydb";
String login = "root";
String passwd = "toor";
Connection cn = null;
Statement st = null;
ResultSet rs = null;
System.out.println("Connecting to database..");

embed MS Access database with runnable jar

So 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. Any form of help would be appreciable.
I've found many tutorials for using Derby database that would implement the same but none pertaining to Ms Access database. Suggestions are welcome !
This is my code:-
