CREATE TABLE ADDRESS (
ID int NOT NULL PRIMARY KEY,
STREET varchar (40) NULL ,
CITY varchar (20) NULL ,
STATE varchar (2) NULL ,
ZIP varchar (10) NULL
);
CREATE TABLE CUSTOMER (
ID int NOT NULL PRIMARY KEY,
LAST_NAME varchar (20) NULL ,
FIRST_NAME varchar (20) NULL ,
ADDRESS_ID int NULL ,
HAS_GOOD_CREDIT int NULL
);
它们之间的对应关系为：
Customer-has-a-Address
Address-belongs-to-Customer
出现下面的Exception：

是不是因为MySQL的原因？
还有，CMP Entity Bean的Local接口主要是用来干什么的？什么时候用？
谢谢！
