軟體印象

1. config servlet in web.xml
 <servlet>
     <servlet-name>addressData</servlet-name>
     <servlet-class>com.xxx.webapp.AddressDataAutoCompleteServlet</servlet-class>
     <load-on-startup>1</load-on-startup>
    </servlet>
   
2. set autocomplete in JSP
$().ready(function() {
 
 $("#addressLine1").autocomplete("<%=StrUtils.filterStr(request.getContextPath())%>/servlet/addressData?paramName=addressLine");
 $("#addressLine2").autocomplete("<%=StrUtils.filterStr(request.getContextPath())%>/servlet/addressData?paramName=addressLine2");
 $("#addressLine3").autocomplete("<%=StrUtils.filterStr(request.getContextPath())%>/servlet/addressData?paramName=addressLine3");
 $("#addressCity").autocomplete("<%=StrUtils.filterStr(request.getContextPath())%>/servlet/addressData?paramName=addressCity");
 $("#addressPostCode").autocomplete("<%=StrUtils.filterStr(request.getContextPath())%>/servlet/addressData?paramName=addressPostCode");
 $("#firstFocusObj").focus();
});

<html:text name="" tabindex="9" style="color: grey;" onclick="clearAddressValue(this)" styleId="addressLine1" value='<%=request.getAttribute("postalAddress1") == null ? defalutAddressValue : (String)request.getAttribute("postalAddress1")%>' property="TLContactDetailForm.postalAddress1" size="50" maxlength="50" styleClass="inputText2"></html:text>

<input type="text" name="TLContactDetailForm.postalAddress1" maxlength="50" size="50" tabindex="9" value="Start typing your address and we will finish it for you" onclick="clearAddressValue(this)" id="addressLine1" style="color: grey;" class="inputText2">

3. return addresses in java class: AddressDataAutoCompleteServlet.java

package com.xxxxxx.webapp;

import javax.servlet.http.HttpServletResponse;

import org.apache.log4j.Logger;

public class AddressDataAutoCompleteServlet extends HttpServlet {
    private static final long serialVersionUID = 1L;
    public Logger LOG = Logger.getLogger(this.getClass().getName());

        LOG.info(paramName);
        LOG.info(paramValue);

        List list = new ArrayList();

        try {
            list = ServiceLocator.getAddressService()
                                 .searchAddressList(paramName, paramValue);
        } catch (ServiceException e) {
         LOG.error(e.getMessage(),e);
        }

        PrintWriter t_PW = response.getWriter();
       
        for (int i = 0; i < list.size(); i++) {
            String address = StrUtils.toTitleCase((String) list.get(i));

            if (paramName.equals("addressLine")) {
             AddressShow.showAddress(t_PW,address);
            } else if (paramName.equals("addressLine1")) {
             AddressShow.showAddress(t_PW,address);

     */
    protected void doPost(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {
        this.doGet(request, response);
    }
}

AddressShow.java

package com.intl.cigna.util;

import java.io.PrintWriter;

public class AddressShow
{
  public static void showAddress(PrintWriter pw, String input)
  {
    pw.write(input + "\n");

  }
}

Description:.

To bring up System Properties:

1.       Click Start and then Control Panel. From the Control Panel, double click System.

2.        Another way to bring up this box is to right click the My Computer on your desktop. From the menu, select Properties.

Solution:

1.       參考http://www.passcape.com/windows_run_commands

除了這兩種方式外，還有一種直接運行system32下面的命令文件方式

運行C:"WINDOWS"system32 下面的sysdm.cpl。

Description: @Override該標記是為了增強程序在編譯時候的檢查，JDK1.5下，如果該方法并不是一個覆蓋父類的方法，在編譯時編譯器就會報告錯誤。

Analisys:

 1public class A {
 2 public void method(int i) {
 3 }
 4}
 5
 6public class B extends A {
 7 @Override
 8 public void method(int i) {
 9 }
10
11//如果如下定義，就會在編譯時出現(xiàn)一個錯誤，因為不是覆蓋父類的方法
12@Override
13 public void method(int i, String p_Str) {
14 }
15
16}
17

JDK1.6正常，支持對接口的實現(xiàn)的@Override

 1public interface iA {
 2
 3 public void method(int i) {
 4
 5 }
 6
 7}
 8
 9public class B implements iA {
10
11 //JDK1.5下會報錯，JDK1.6下可以
12
13 @Override
14
15 public void method(int i, int j) {
16
17 }
18
19}
