Thanks for your reply. I changed
person.setId("stsch");
to
person.setId(KeyFactory.stringToKey("stsch"));
and
@Id
private String id;
to
@Id
Key String id;
but I am still getting the same error:
java.lang.IllegalArgumentException: Cannot parse: stsch===

com.google.appengine.api.datastore.KeyFactory.stringToKey(KeyFactory.java:
