What is ConnectionLocator/MidpointLocator?
I write :
label.setText("Test");
connection.add(label);
in createFigure(),but it doesn't display the text.

label.setText("line");

connection.add(label,new
ConnectionLocator(connection,ConnectionLocator.MIDDLE));
return connection;
}
Any problem with this method?

Your code seems fine.
What exactly is going wrong? Is your connection line being displayed
correctly?
Try removing the BendpointConnectionRouter OR maybe you can use the
ManhattanConnectionRouter just to check.
Best,
Brian.
