13. 針對PictureWSP建立Web Service並產生wsdl檔-part1
14. 針對PictureWSP建立Web Service並產生wsdl檔-part2
15. 查詢wsdl檔-part1
16. 查詢wsdl檔-part2
17. 查詢wsdl檔-part3
18. 查詢wsdl檔-part4
19. 上網輸入 http://localhost:8080/PictureWSP/services/PictureWSP?wsdl (可更改localhost為你的IP Address,Android會透過wsdl將資料在雲端進行操作)
20. 以下為wsdl檔的模樣
21. 匯入MySQL的JDBC Driver-part1(下列為連結網址)
22. 匯入MySQL的JDBC Driver-part2
23. 下載完成並安裝,到C:\Program Files (x86)\MySQL\MySQL Connector J目錄下可找到mysql-connector-java-5.1.31-bin.jar
24. 匯入MySQL的JDBC Driver(將mysql-connector-java-5.1.31-bin.jar複製到專案裡的WebContent/WEB-INF/lib)
建立Android Client,並整合Web Service與MySQL
1. 開啟Eclipse ADT
2. 建立專案-part1
3. 建立專案-part2
4. 建立專案-part3(一直按Next到如下畫面)
5.匯入SOAP.jar檔,以下網址有教你如何匯入到專案

1. 透過Web Service讀取MySQL資料庫的資料
- Android Client透過Web Service讀取MySQL的所有資料,該資料為圖片存於主機上的路徑位置,透過該路徑讀取圖片,並回傳到Android Client UI顯示圖片
2. 透過Web Service寫入資料到MySQL資料庫
實作步驟
- 在Android Client讀取一張圖片,並透過Web Service將Android Client所讀取的圖片寫入到主機的目錄上並將主機目錄上的路徑寫入MySQL
1. 建立MySQL資料庫MySQL資料庫設計實作
2. 建立Web Service with java
3. 建立Android Client,並整合Web Service與MySQL
1. 啟動 appserv-win32-2.5.10.exe ,並以系統管理員身分執行

CREATE TABLE picture (
id INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
path TEXT NOT NULL
) ENGINE = MYISAM ;
12. 在主機上的C槽底下建立名稱為picture的目錄
實作建立Web Service with java
1. 開啟 Eclipse EE
2. 建立Tomcat Server,請點選以下連結
建立Tomcat Server 網址3. 安裝axis2-part1

13. 針對PictureWSP建立Web Service並產生wsdl檔-part1
14. 針對PictureWSP建立Web Service並產生wsdl檔-part2
15. 查詢wsdl檔-part1
16. 查詢wsdl檔-part2
18. 查詢wsdl檔-part4
19. 上網輸入 http://localhost:8080/PictureWSP/services/PictureWSP?wsdl (可更改localhost為你的IP Address,Android會透過wsdl將資料在雲端進行操作)
20. 以下為wsdl檔的模樣
MySQL JDBC Driver Download
22. 匯入MySQL的JDBC Driver-part2
23. 下載完成並安裝,到C:\Program Files (x86)\MySQL\MySQL Connector J目錄下可找到mysql-connector-java-5.1.31-bin.jar
24. 匯入MySQL的JDBC Driver(將mysql-connector-java-5.1.31-bin.jar複製到專案裡的WebContent/WEB-INF/lib)
建立Android Client,並整合Web Service與MySQL
1. 開啟Eclipse ADT
2. 建立專案-part1
4. 建立專案-part3(一直按Next到如下畫面)
5.匯入SOAP.jar檔,以下網址有教你如何匯入到專案
匯入SOAP.jar
下列為Android程式碼
