I tweaked the schema a bit to fix id references and make sure an id is declared before it is referenced.

var statement = {
    "id" : "fd41c918-b88b-4b20-a0a5-a4c32391aaa0",
    "actor" : {
        "objectType" : "Blowup",
        "name" : "Project Tin Can API",
        "mbox" : "mailto:[email protected]"
    },
    "verb" : {
        "id" : "http://adlnet.gov/expapi/verbs/created",
        "display" : {
            "en-US" : "created"
        }
    },
    "object" : {
        "id" : "http://example.adlnet.gov/xapi/example/simplestatement",
        "definition" : {
            "name" : {
                "en-US" : "simple statement"
            },
            "description" : {
                "en-US" : "A simple Experience API statement. Note that the LRS does not need to have any prior information about the Actor (learner), the verb, or the Activity/object."
            }
        }
    }
};
var schema = {

Unfortunately that looks like an older version of JSON-Schema. The current version (what JaySchema uses) is v4 and that looks like v3. v4 is a lot different so it isn’t going to work without major changes to the schema.
