1.連接池
a.點擊項目名稱，右鍵選擇New(新建)->other...
b.在categories選框里選擇：Glassfish 右邊File types(文件類型)選擇：JDBC Connection Pool
c.JDBC Connection Pool Name(JDBC連接池名稱)：輸入BlogPool；連接之前創建的blogs庫。
d.全部默認選項，按finish(完成),連接池算是創建完成了。
2. 數據源
按步驟1-a,1-b選擇JDBC Resource
c.Gerneral Attributes(一般屬性）Connection Pool選擇Use Existing JDBC Connetion Pool（使用已有的連接池）
下拉單里選擇剛剛創建的BlogPool，JNDI Name里填寫：jdbc/Blog
Finish以后，在項目的Server Resources的sun-resources.xml文件里可以查看到連接池和數據源的信息。
