Hi,
I am getting OutOfMemoryError in my java swing application as below.
Exception occurred during event dispatching:
java.lang.OutOfMemoryError

Is it possible to fix this?

Where is the class itm.map.MapView coming from? What is the code supposed to do?

Have you tried reserving more heap space?

It is very easy to create memory "leaks" in Swing if you don't properly dispose of listeners. The swing forum is where you will get help on this.
