为什么这里老是报错？多谢！

try{
..........

}
catch(Exception e){
return null;
}
finally{
if (i_CallableStatement!=null) {ipst.close();}
if (i_Connection!=null){iconn.close();}
}

报错：
"loginBean.java": Error #: 360 : unreported exception: java.sql.SQLException; must be caught or declared to be thrown at line 43, column 38
