            log  =    new  PrintWriter( new  FileOutputStream(fl, true ), true );
            SimpleDateFormat df  =   new  SimpleDateFormat( " yyyy.MM.dd 'at' hh:mm:ss\n " );
            Date now  =   new  Date();
            String dateformat  =  df.format(now)
            BufferedWriter bf   =   new  BufferedWriter( new  FileWriter(fl,  true ));
            bf.append(dateformat);
            bf.close();
            log.println( " start connection databse: " );
            log.println( " driver name: " .concat(driveName);


输出的结果示例:
2006.12.12 at 10:21:13
start connection databse:
driver name:oracle.jdbc.driver.OracleDriver

错误的原因：
在nonregsiter中已经手动删除了id=‘82’的记录，而在WF_task以及wf-proces中还有bizclass = '3' && bizId = '82'的记录,只要删除wf-task中相应的记录.

 <bean id="baseDAO" class="com.aimy.core.dao.impl.BaseDAOImpl">
相当于
basedaoimpl baseDAO = new BaseDAOImpl();
2,通过静态工厂创建bean
<bean id="driver1" class="com.aimy.driver.driverManager"
factory-method="createInstance"/>
相当于
Object driver1 = driverManager.createInstance();

其中没有指定driverManager.createInstance();返回对象的类型，而且createInstance()必须是static方法
3，通过实例工厂方法创建bean
＜bean id="father" class="com.aimy.Father"/>
．．．．．．．．
<bean id="son" factory-bean="father" factory-method="createSon"/>
相当于
Father father = new Father();
Object son = father.createSon();

其中father和son必须在同一个bean工厂或父bean工厂，即在同一个applicationcontext或子applicationcontext


二、如果applicationcontext默认预实例化那些singleton　bean，这样就可以在beanfactory装载时就检查出错误，而如果singleton　bean设置为lazy－mode，

  <typeAlias alias="ID" type="com.xindeco.core.pojo.IDEntity"/>
  </select>
   <select id="GraAppInfo.searchUpApply" parameterClass="com.xindeco.business.dto.GraAppInfoDTO"    resultClass="ID" cacheModel="userCache">

   </dynamic>
  </select>
</sqlMap>

注意sqlmapGraAppInfoDTO的name，unit只能是基本数据类型，不能是复杂数据类型．
２、<script>的位置
<script>
form1.srchEdit.value='<%=srchEdit%>';
form1.srchType.value='<%=srchType%>';    
</script>
<form>
<input type="text" name="srchEdit"/>
<input type="text" name="srchType"/></form>
与<form>
<input type="text" name="srchEdit"/>
<input type="text" name="srchType"/>
</form>
<script>
form1.srchEdit.value='<%=srchEdit%>';
form1.srchType.value='<%=srchType%>';    
</script>
的差别，必须在form加载完对它赋值，否则srchEdit又重新加载，为null

3、hibernate属性设置出现错误：
      如果pojo类取fSUnit属性名，系统将无法识别。get和set将取不到值。
