I wrote simple procedure which returns cities of a country :

CREATE DEFINER="root"@"localhost" PROCEDURE "select_city"(country INT)
BEGIN
   SELECT city_name FROM CITY WHERE country_id=country;
END $$

In Dropdown.xml :

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//
EN"
    "http://ibatis.apache.org/dtd/sql-map-2.dtd">

<sqlMap namespace="Dropdown">
   <select id="allCities" resultClass="java.util.HashMap">
        SELECT * FROM CITY
   </select>
  <parameterMap id="Parameters" class="map" >
             <parameter property="country" jdbcType="INTEGER"
javaType="java.lang.Integer"
                   mode="INOUT"/>
  </parameterMap>
  <procedure id="getCountries" parameterMap="Parameters" >
        {call select_city(?)}
  </procedure>
</sqlMap>

In Action class :
                HashMap paramMap = new HashMap();
        paramMap.put("country", new Integer(91));
        result = dropDownDAO.getCountries(paramMap);

In DAO class:
               public List getCountries(HashMap hashMap) throws
Exception {
        List dd = (List)sqlMap.queryForList("getCountries",hashMap);
        return dd;
        }

In sqMapConfig.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE sqlMapConfig
PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"
"http://ibatis.apache.org/dtd/sql-map-config-2.dtd">
<!-- Always ensure to use the correct XML header as above! -->
<sqlMapConfig>

        file (e.g. "${driver}". The file is relative to the classpath
and is

        <properties resource="resources/sqlMapConfig.properties" />

        <!-- Configure a datasource to use with this SQL Map using

DBCP
        notice the use of the properties from the above resource -->

   <transactionManager type="JDBC" commitRequired="false">
   <dataSource type="DBCP">

                <property name="Pool.MaximumIdleConnections" value="5"/

                <property name="Pool.MaximumCheckoutTime"
value="120000"/>
                <property name="Pool.TimeToWait" value="500"/>

        </dataSource>
  </transactionManager>

 <!-- Identify all SQL Map XML files to be loaded by this SQL map.
Notice the paths
        are relative to the classpath. For now, we only have one? -->
        <sqlMap resource="sql/DropDown.xml" />
</sqlMapConfig>

Please help me out on this issue
