<jsp:useBean id="user" class="UserData" scope="session"/>
<HTML>
<BODY>
<FORM METHOD=POST ACTION="SaveName.jsp">
What's your name? <INPUT TYPE=TEXT NAME=username
SIZE=20 VALUE="<%= user.getUsername() %>"><BR>
What's your e-mail address? <INPUT TYPE=TEXT
NAME=email SIZE=20
VALUE="<%= user.getEmail() %>"><BR>
What's your age? <INPUT TYPE=TEXT NAME=age
SIZE=4 VALUE=<%= user.getAge() %>>
<P><INPUT TYPE=SUBMIT>
</FORM>
</BODY>
</HTML>
如上面的代碼所示，它只簡單地在INPUT標誌上增加一個“VALUE”地區，並且用一個表達是初始化這個地區。
為了處理在輸入過程中的異常錯誤，我們可以在bean中使用“String”地區並且將它轉換為目標資料類型就可實現。所以這樣也可以處理異常錯誤。
作為課後練習，我們可以將前面教程中的例子改成不用Blazix標誌庫。
至此，本“JSP由淺入深”系列教程到此全部結束，希望對你有協助。
