Edit Image in JAVA Applet

We need to create a Java Applet will be used on the NET using Browser,  which is used for Shipment of the items through Ships. In this Application where ever the ship will move we will get the location of the ship and the line will drawn on the map.

Now the following task we have to do as an R&D

1. Suppose we get the location from delhi to mumbai, Then we have to to draw the line between delhi to Mumbai on the image Map of India.

2. We have to add another image on the destination point i.e., on mumbai we have to put flag on the destination point.

3. When ever we click on the flag we should get the tool tip.

In Short I wish

That line to be drawn on Applet and I wish to keep the One Image on another and then bookmark or make link on that Image

Can anyone help me to give the solution and the best way to do this?

Can I get the applet code

Thanks in Advance
