Retrieve Image from SQLITE DB and open it in imageView using JFXbutton - database

Question

I'm trying to create desktop App (scenebuilder) and I want to retrieve path of Image from DATABASE (SQLITE) and Attach it to button to open it in ImageView but I'm facing a problem while doing that.
Note: I'm trying to learn Java
My code
#FXML
private ImageView imageView;
#FXML
void btn10 (ActionEvent event) {
Connection c = null;
Statement stmt = null;
try {
Class.forName("org.sqlite.JDBC");
c = DriverManager.getConnection("jdbc:sqlite:sogeclair.sqlite");
c.setAutoCommit(false);
System.out.println("Opened database successfully");
stmt = c.createStatement();
String sql = "SELECT * FROM image WHERE rowid = 1" ;
System.out.println(sql);
ResultSet rs = stmt.executeQuery( sql );
while ( rs.next() ) {
String path=rs.getString("imaging");
imageView.setImage(new Image(path));
System.out.println();
}
rs.close();
stmt.close();
c.close();
} catch ( Exception e ) {
System.err.println( e.getClass().getName() + ": " + e.getMessage() );
System.exit(0);
}
System.out.println("Operation done successfully");
}
and I got this in result
Opened database successfully
SELECT * FROM image WHERE rowid = 1
java.lang.IllegalArgumentException: Invalid URL: Invalid URL or resource not found

and MyDatabase
All comments are welcome :D help me please :D

This is code from a program I wrote that retrieves an image blob from sqlite. You can download and run the program from here. It's running, but it's an incomplete program.
In your code, once you get the image using ideas from my code then just use that image to set your ImageView.
String sqlTCNote = "SELECT * FROM Company;";
try (Connection conn = DriverManager.getConnection("jdbc:sqlite:contactFX.db");
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery(sqlTCNote))
{
while(rset.next())
{
Company c1 = new Company();
c1.setName(rset.getString("company_name"));
c1.setShortName(rset.getString("short_name"));
c1.setStreet(rset.getString("street"));
c1.setCity(rset.getString("city"));
c1.setState(rset.getString("state"));
c1.setZip(rset.getString("zip"));
c1.setPhoneNumber(rset.getString("phone_number"));
c1.setTollFreeNumber(rset.getString("toll_free_number"));
c1.setEmailAddress(rset.getString("email_address"));
c1.setMissionStatement(rset.getString("mission_statement"));
c1.setPersonalNote(rset.getString("personal_note"));
c1.setWebSiteAddress(rset.getString("website_address"));
//This is the part you are interested in!
InputStream input = rset.getBinaryStream("image");
InputStreamReader inputReader = new InputStreamReader(input);
if(inputReader.ready())
{
File tempFile = new File("tempFile.jpg");
FileOutputStream fos = new FileOutputStream(tempFile);
byte[] buffer = new byte[1024];
while(input.read(buffer) > 0){
fos.write(buffer);
}
Image image = new Image(tempFile.toURI().toURL().toString());
c1.setImage(image);
}
for(int i = 0; i < 10; i++)
{
c1.addEmployee(new Employee());
}
companyData.add(c1);
}
}
catch(SQLException ex)
{
Logger.getLogger(MainController.class.getName()).log(Level.SEVERE, null, ex);
}
catch (IOException ex)
{
Logger.getLogger(MainController.class.getName()).log(Level.SEVERE, null, ex);
}
