Spring: HSQL- Failed to execute database script

I'm trying to run HSQL with following two scripts and then test it, but each time I get this error which I cannot handle.

Failed to execute database script; nested exception is org.springframework.jdbc.datasource.init.ScriptStatementFailedException: Failed to execute SQL script statement at line 4 of resource class path resource [data.sql]: insert into spittle (spitter_id, spittleText, postedTime) values (2, 'Trying out Spring''s new expression language.', '2010-06-11')

Update - additional exception that has been thrown:

integrity constraint violation: foreign key no parent; SYS_FK_10108 table: SPITTLE

These are my scripts:

schema.sql

drop table if exists spittle;
drop table if exists spitter;

create table spitter (
  id identity,
  username varchar(25) not null,
  password varchar(25) not null,
  fullname varchar(100) not null,
  email varchar(50) not null,
  update_by_email boolean not null
);

create table spittle (
  id integer identity primary key,
  spitter_id integer not null,
  spittleText varchar(2000) not null,
  postedTime date not null,
  foreign key (spitter_id) references spitter(id)
);

data.sql

insert into spitter (username, password, fullname, email, update_by_email) values ('habuma', 'password', 'Craig Walls', '[email protected]', false);
insert into spitter (username, password, fullname, email, update_by_email) values ('artnames', 'password', 'Art Names', '[email protected]', false);

insert into spittle (spitter_id, spittleText, postedTime) values (1, 'Have you read Spring in Action 3? I hear it is awesome!', '2010-06-09');
insert into spittle (spitter_id, spittleText, postedTime) values (2, 'Trying out Spring''s new expression language.', '2010-06-11');
insert into spittle (spitter_id, spittleText, postedTime) values (1, 'Who''s going to SpringOne/2GX this year?', '2010-06-19');
