chstr.java

采用TOMCAT+SQL编程

package shudian;
public class chStr
{public String chStr(String str)
   {if(str==null){str="";}
    else
      {try
          {str=(new String(str.getBytes("iso-8859-1"),"GB2312")).trim();
          }catch(Exception e){e.printStackTrace(System.err);}
      }
   return str;
    }
}
