In my application I have two different swingworkers (they do two different jobs). The first one works perfectly, while the latter does not.
What I can do to fix it?
class worker extends SwingWorker<Boolean, String> {
@Override
protected Boolean doInBackground() throws Exception {
getstub().registration(name.getText(), surname.getText());
return true;
}
protected void done() {
boolean status;
try {
status = get();
regstatus.setText("registration status: " + status);
} catch (InterruptedException e) {
} catch (ExecutionException e) {
}
}
}
class worker1 extends SwingWorker<Boolean, String> {
@Override
protected Boolean doInBackground() throws Exception {
int i = Integer.parseInt(id.getText());
double r = Double.parseDouble(range.getText());
double la = Double.parseDouble(lat.getText());
Coordinate lat = new DegreeCoordinate(la);
double lo = Double.parseDouble(lon.getText());
Coordinate lon = new DegreeCoordinate(lo);
System.out.println("id: "+i+" lat: "+la+ " lon: "+lo+" type: "+type.getText()+ " range: "+r);
getstub().request(i, lat ,lon ,type.getText(), r);
return true;
}
protected void done() {
boolean status;
try {
status = get();
reqstatus.setText("request status: " + status);
} catch (InterruptedException e) {
} catch (ExecutionException e) {
}
}
}
and two jbuttons that start the worker
private JButton register = new JButton("Register");
register.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
new worker().execute();
}
});
private JButton search = new JButton("Search now");
search.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent arg0) {
reqstatus.setText("I'm searching...");
new worker1().execute();
}
});
The problem in large scope
Looks like you're using ninja-exception-logging (the invisible one):
Do some real logging there and you will most probably see the problem. At least use
System.out.println()
; a better choice is log4j.The particular mistake
With logging enabled, a
NumberFormatException
, wrapped in theExecutionException
was found.
