 }

 public void setId(JsryId id) {

 }
}

public void save(Jsry jsry) {
  log.debug("saving Jsry instance");
  try {

<? xml version = " 1.0 "  encoding = " gb2312 " ?>
<!-- DOCTYPE service - config SYSTEM  " service.dtd " -->
< service - config >
     <!--  用户服务  -->
     < service name = " UserService "   class = " com.xainfor.service.UserService "  template = " normal "   />
     < service name = " GnmkService "   class = " com.xainfor.service.GnmkService "  template = " normal "   />
</ service - config >  

第二步:系统初始化是将所有服务名和路径加载到一个静态的HashMap中

public   class  ServiceConfig  {
    
     public   static  HashMap serviceMap  =   new  HashMap();
    
     public   static  String getService(String serviceName)  {
        String serviceClass  =   "" ;
        serviceClass  =  ServiceConfig.serviceMap.get(serviceName).toString();
         return  serviceClass;
    }
}

第三步:定义一个接口类

public   interface  Service  {
  public   void  execute();
}

public class ServiceExecuteHelper {
    
    /** *//**
     * 日志处理
     */
    private static final MsgLogger logger = MsgLogger.getLogger();
    
     public static void execute(String servicename) {
         try {
            //验证服务是否存在
            String servicClass = ServiceConfig.getService(servicename);
            //如果服务存在就加载服务信息
            if (servicClass != null && !servicClass.equals("")) {
                Class classObject = Class.forName(servicClass);
                Service service = (Service) classObject.newInstance();
                service.execute();                            
            } else {
                logger.info("服务["+servicename+"]未定义");
            }
        } catch(Exception e) {
            logger.info("服务["+servicename+"]不存在!");
        }
     }
}

public class GnmkService implements Service {

    /**//* (non-Javadoc)
     * @see com.xainfor.service.Service#println()
     */
    public void execute() {
        // TODO Auto-generated method stub
        System.out.println("执行的是GnmkService");
    }

}

public class UserService implements Service {
    
    public void execute() {
        // TODO Auto-generated method stub
        System.out.println("执行的是UserService");
        
    }
}

public class testService {
   
    public static void main(String [] temp) {
      ServiceExecuteHelper.execute("UserService");
   }
}

     最新的oracle10g的driver，已经解决了这些问题。我项目用ojdbc14-10.2.0.3.0.jar连接oracle9i数据库,可以正常读写CLOB。
         Hibernate存取Clob和Blob对象，将 clob用string方式处理。
         Hibernate Annotations方式,只要映射成Lob类型就可以，对该字段的读写，就是一般的操作方式。

        @Lob
    public String getTxt() {
        return txt;
    }

}
//删除cookie
function deleteCookie(name)
{
    var exp = new Date();
    exp.setTime(exp.getTime() - 1);
    var cval=getCookie(name);
    if(cval!=null)
    document.cookie= name + "="+cval+";expires="+exp.toGMTString();
}

 //checkbox全不选
function checkboxNoAll(itemName)
{
var item = document.getElementsByName(itemName);
for (var i=0; i<item.length; i++)
{
item[i].checked = false;
}
}
//checkbox中选择一条
function checkCount(itemName)
{
   var intCount=0;
  var item = document.getElementsByName(itemName);
   if (item.length>1){
      for(i=0;i< item.length;i++)
      {
          if(item[i].checked)
          intCount=intCount+1;
      }
   } else {
      if(item[0].checked)
      intCount++;
   }
   return intCount;
}

   1. logger的level越低，表示该logger越详细
   2. logging request的level越高，表示该logging request越优先输出

Level类中预定义了五个level，它们的大小关系如下：
Level.DEBUG < Level.INFO < Level.WARN < Level.ERROR < Level.FATAL

                                                                      在代码中打印日志
第一步是取得LOG，LOG采用APACHE的COMMON-LOGGING包来获得。
protected static Log log = LogFactory.getLog(XXX.class);

第二步就是LOG的输出，LOG输出只需要填写描述性文字，不要在LOG输出中包含任何类名，时间，日志级别等信息。输出LOG时必须检测当前LOG的输出配置情况。
if (log.isDebugEnabled()) {
            log.debug("Initializing module path '" + config.getPrefix() +
                "' data sources");
}

                                                        修改LOG配置文件，打印自己模块的LOG
在系统的configs目录下，已经有了缺省的LOG4J配置文件log4j.properties。
缺省配置下包括了打印IBATIS和JDBC执行情况
# JDBC logging configuration...
log4j.logger.com.ibatis=DEBUG
log4j.logger.java.sql=DEBUG
log4j.logger.org.springframework.jdbc.core=DEBUG

如果想记录自己的开发类的日志，可以简单的增加一行
log4j.logger.com.spsoft.sample.service=DEBUG
log4j.logger.com.spsoft.sample.service.dao.SampleDao=INFO
com.spsoft.sample.service是包名，当然也可以直接指定类名。
