ibatis 调用存储过程报java.lang.NullPointerException错，请问

[capricornwq]

xml:
<parameterMap id="invoiceInsertMap" class="map" >
<parameter property="invoicestart" jdbcType="NUMBER" javaType="java.lang.Long" mode="IN"/>
<parameter property="totalnum" jdbcType="NUMBER" javaType="java.lang.Integer" mode="IN"/>
<parameter property="invoicebookid" jdbcType="NUMBER" javaType="java.lang.Integer" mode="IN"/>
</parameterMap>
<procedure id="invoiceInsert" parameterMap="invoiceInsertMap" >
{call invoiceInsert (?,?,?)}
</procedure>
调用：
public int invoiceInsert(InvoiceBook invoicebook) {
HashMap paramMap = new HashMap();
paramMap.put("invoicestart", invoicebook.getInvoicestart());
paramMap.put("totalnum", invoicebook.getInvoicedicid());
paramMap.put("invoicebookid", invoicebook.getInvoicedicid());
return invoiceDao.invoiceInsert(paramMap);
}

报java.lang.NullPointerException错

向大虾们请教

有人知道么？？？？　　50分相送！！！

还是不同样的报错
(1)我的xml：
<parameterMap id="invoiceInsertMap" class="java.util.map" >
<parameter property="invoicestart" jdbcType="NUMBER" javaType="java.lang.Long" mode="IN"/>
<parameter property="totalnum" jdbcType="NUMBER" javaType="java.lang.Integer" mode="IN"/>
<parameter property="invoicebookid" jdbcType="NUMBER" javaType="java.lang.Integer" mode="IN"/>
</parameterMap>
<procedure id="invoiceInsert" parameterMap="invoiceInsertMap" >
{call invoiceInsert (?,?,?)}
</procedure>
(2)invoiceInsert 为数据库中存储过程，代码无误

(3)对外调用的接口：
public int invoiceInsert(InvoiceBook invoicebook) {
HashMap paramMap = new HashMap();
paramMap.put("invoicestart", invoicebook.getInvoicestart());
paramMap.put("totalnum", invoicebook.getInvoicedicid());
paramMap.put("invoicebookid", invoicebook.getInvoicebookid());
return invoiceDao.invoiceInsert(paramMap);

}
(4)invoiceDao 对xml配置中调用：
public int invoiceInsert(HashMap paramMap) {
int i=0;
try{
daoManager.startTransaction();
i=((Integer)queryForObject("invoiceInsert",paramMap)).intValue();
daoManager.commitTransaction();
}catch(Exception e ){
e.printStackTrace();
}
return i;
}

控制台打印的结果
{call invoiceInsert (?,?,?)}
[100000000, 20, 1]
Types: [java.lang.Long, java.lang.Integer, java.lang.Integer]
java.lang.NullPointerException
再次求教，如果可以给个实例，也万分感谢!!!

<parameterMap id="invoiceInsertMap" class="map" >
把 map写完整 （java.util.map）看看行不行
或者<alias>
<typeAlias alias="map" type="java.util.map" />
</alias>
