Is there a way to serialize an object to a specific location? I have a class (will post code) in a package that I "C:\>java" from the \classes directory, where the \com folder is, and it serializes the object in \classes, as opposed to the location of the actual class file.
If you use a relative path name in a FileOutputStream, then that path is relative to the current working directory. If you want it to go somewhere else, then use an absolute path. (This is simply a fact about path names, not about serialization per se.)
I don't think it's a good idea to put changeable data in the same directory where your classes are located, anyway. Perhaps you should put your data in the user's home directory, or a subdirectory of that which you create specifically for your application.
