Serializable

[Candy Bortniker]

I am getting this error when I try to write to the file, NotSerializableException. How do I fix this? This is the code that I think is throwing the error.

if (e.getActionCommand() == "Done")
{ //write vector to file
try
{ ObjectOutputStream oos = new ObjectOutputStream (
new FileOutputStream( "account.txt" ) );
oos.writeObject ( transaction );
oos.close (); }
catch ( Exception ex )
{ System.out.println ( "Error " + ex ); }
}//end Done

The object pointed to by "transaction" must belong to a class that declares that it "implements java.io.Serializable", or you'll get this exception.
