使用 Ibatis 2.3 检索 CLOB 数据

Question

我正在尝试从 oracle 数据库检索 clob 数据，如 reports.xml 中所示。我正在使用 oracle jdbc 驱动程序版本“Oracle JDBC 驱动程序版本 - 10.0.2.0.0”。以下是我收到的错误，请告诉我如何解决这个问题。

reports.xml

<select id="getReportQuery"  parameterClass="java.util.HashMap" resultMap="queryStringData" >
        select REPORT_QUERY 
         from frd_rep_fw_reports where report_id=#REP_ID# AND report_type='P' 
</select> 
<resultMap id="queryStringData" class="java.util.HashMap">
  <result column="REPORT_QUERY" property="QRY_BODY" javaType="java.lang.String" jdbcType="CLOB"  typeHandler="com.ibatis.sqlmap.engine.type.ClobTypeHandlerCallback" />
</resultMap>    

sqlmapconfig.xml

<dataSource type="JNDI">
        <property name="DataSource" value="${connection.datasource}"/>
        <property name="Driver.SetBigStringTryClob" value="true"/>
    </dataSource>

获取最新的 ojdbc14.jar 我应该可以工作。另请让我知道表 frd_rep_fw_reports 是如何定义的
