How to read/resolve a serialized object?

[James Davison]

I created two methods to read/write serialized objects. The basic code for the read is shown below. Initially, both methods worked fine when contained in a class in the same Eclipse project as the class objects I was serializing. However, since it is generic code, I attempted to move the code to a separate utility project. The read code now fails with a ClassNotFoundException when it attempts to load a serialized file. I suspect it is a classloader issue because, within the utility project code, I can load the class to be read from a file using the Thread context class loader but not with the class loader that loaded the class containing the read/write methods. However I am unsure how to make this work. Any suggestions?

                // Read from disk using FileInputStream
                java.io.FileInputStream f_in = new java.io.FileInputStream(this.getName(id));
 
                // Read object using ObjectInputStream
                java.io.ObjectInputStream obj_in = new java.io.ObjectInputStream (f_in);
 
                // Read an object
                return obj_in.readObject();
