ClassCastException during deserialization

[Himanshu Gupta]

I am getting the ClassCastException when I try to deserialize the Object.
I tried to print the name of the class and it displays the same class.

try {
			
			vIHData = (SymRegIHData) pInfoHabitant.getData();
		} catch (Exception e) {
			e.printStackTrace();
			System.out.println("**************8 "
					+ pInfoHabitant.getData().getClass().getName());
			System.out.println(pInfoHabitant.getData().toString());
		}

Error Trace:

Does anyone has any idea about this. If yes then please share your thoughts.

Thanks in advance.

You must have used a different class loader to load the class of the serialized object. That's the only way I can explain two classes with the same name not being the same - class equality is defined by the name and class loader only.

I think its the same issue. Any idea how to fix issues like this.

Thanks for your valuable reply. It helped.
