Can you list the errors and the project version (e.g. s3v1)?

s3v5 is where I copied teh treets.ser from.

Error loading treets. java.lang.ClassNotFoundException: com.teamtreehouse.Treet at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at java.io.ObjectInputStream.resolveClass(Unknown Source) at java.io.ObjectInputStream.readNonProxyDesc(Unknown Source) at java.io.ObjectInputStream.readClassDesc(Unknown Source) at java.io.ObjectInputStream.readArray(Unknown Source) at java.io.ObjectInputStream.readObject0(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at com.treehouse.Treets.load(Treets.java:14) at Example.main(Example.java:12)

This is how I am trying to load it:

public static Treet[] load() {
        Treet[] treets = new Treet[0];
        try(
            FileInputStream fis = new FileInputStream("treets.ser");
            ObjectInputStream ois = new ObjectInputStream(fis);
        ) {
            treets = (Treet[]) ois.readObject();
        } catch(IOException ioe) {
            System.out.println("Error reading file");
        } catch(ClassNotFoundException cnfe) {
            System.out.println("Error loading treets.");
            cnfe.printStackTrace();
        }
        return treets;
    }

Did you happen to change the package that Treet and Treets were put in while copying the files?

Yeah that would be it. My package is just called com.treehouse whereas workspaces called it com.treehouse.treets

I just had a look in the .ser file and it specifies the package directory (I think) so that would be why it cant load them. At least I know it isnt my code now but rather just a directory issue

if you change the package declaration to

package com.teamtreehouse;

for Treet and Treets (and then have Eclipse refactor) it should load the file without issue.

Thanks.
