PostgreSQL Money type :: how to map it to Hibernate JPA?

I seem to be having problems mapping the PostgreSQL money type to the java.util.Currency type using the following JPA snippet:

@Basic(optional = true)                                 
@Column(name = "cafl_bubgeted_amount")
private Currency bubgetedAmount;

column cafl_budgeted_amount is of type money in PostgreSQL.
When the code is deployed in JBoss AS 7.1.1 I get the trace shown at the end of the post. Has anybody handled that mapping ?

trace when deployed in JBoss AS 7.1.3

一个java.util.Currency表示一种货币，比如USD或EUR，而不是Postgres MONEY中的456.34这样的实际金额。例外是因为它试图将数字解析为货币代码。

我强烈建议目前不要使用MONEY，而使用NUMERIC。这里有一些具体的问题。它在算术方面的表现不如NUMERIC好，而且它所代表的货币取决于您的本地化设置，这意味着一旦您需要多种货币，就会发生不好的事情。更糟糕的是，具有不同本地化设置的两个不同用户将看到相同的金额，但指定了不同的货币.....
此外，DECIMAL和NUMERIC比MONEY更好地支持跨数据库（但DECIMAL只是PostgreSQL中NUMERIC的单向别名），所以使用最小公分母建议使用更通用的、无损的10进制浮点数，而不是具有有趣的角落情况和陷阱的专门货币数量。

According to Cris Travers suggest, yo can change your money column to numeric type with an script like this one:

ALTER TABLE MY_TABLE_NAME
Alter column MY_COLUMN_NAME
type numeric(12,2);
