Ekke, Started using 4.0.2, but getting same error. This is how I am loading the Package : this.pkg = new Package(); this.pkg.readExternal(ois); Does that look right to you?

Ekke, Thanks a lot! It worked just fine... The other missing point is that after deserializing the PackageBuilder should be buit as in your example : builder = new PackageBuilder((Package)ois.readObject()); and later on from that isnatcne should be retrieved the Package inctance by doing: package = buider.getPackage(); as otherwise this code was failing: package = (Package)ois.readObject(); // FAILES, subsequent use of package produces "class not found" exception when inserting objects. Mark, Think this should be documented somewhere in manual... under IMPORTANT section... by the way, IMHO that section should be more visible from what is used currently in manual... - thin italic font, how about bold red?

You should be able to serialise a Package without having to first add it to PackageBuilder, we have numerous tests for this. Mark, I looked at the test in PackageBuilderTest.testSerializable(), but it is too syntetic, f.e. it doesn't use insert(...) function as I do in my scenario. Please try creating a test with inserting some MyClass() after deserializing without recreating PackageBuilder and you will see it failing. I made many tests suggesting that. Even when I use DroolsObjectInputStream() -Sergey
