geoserver发布oracle georaster 栅格数据错误

http://hi.baidu.com/perneter/item/5042ee0cf93aaa13addc7004 中按照上面的步骤一步一步做，确在最后一步添加好xml后频频报错，
最后竟然是这个错，Could not list layers for this store, an error occurred retrieving them: sourceXSubsampling <= 0!

我的配置文件是：gddst.xml
内容：
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<config version="1.0">
     <coverageName name="terrametrics"/>
     <coordsys name="EPSG:4326"/>
     
     <scaleop interpolation="1"/>
     <verify cardinality="false"/>

     
     <spatialExtension name="georaster"/>
     <mapping>
         <masterTable name="TEST" >
             <geoRasterAttribute name="IMAGE"/>
             <coverageNameAttribute name="IMAGE_DESCRIPTION"/>
         </masterTable>
     </mapping>

     
     <connect>
         
         <dstype value="DBCP"/>
     

         <username value="HZJCSYS" />
         <password value="HZJCSYS" />

         <jdbcUrl value="jdbc:oracle:thin:@127.0.0.1:1521:ORCL11" />
           <driverClassName value="oracle.jdbc.OracleDriver"/>
         <maxActive value="10"/>
         <maxIdle value="0"/>
     </connect>
</config>

然后是tomcat中报的错误：

数据库中是：

上面说的问题，貌似是图片什么获取不到分辨率，求解。。。

补充：Java ,  Java相关
