In this example you
will learn how to use Struts HTML Tags. In order to use the Struts HTML Tags
you need to include the following taglib directive in the jsp page.
1.<%@taglib
uri="/WEB-INF/struts-html.tld" prefix="html" %>
All the Struts HTML
tags should be nested within the body of the <html:form /> tag. We will
create a simple feedback form to see how the different Struts HTML Tags can be
used. The feedback.jsp contains the following code.
01.<%@taglib
uri="/WEB-INF/struts-html.tld" prefix="html" %>
02.<html>
03.<head>
04.<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
05.<title>Feedback Form</title>
06.</head>
07.<body>
08.<b>Feedback Form</b>
09.<hr>
10.<html:form action="/feedbackAction">
11.<table>
12.<tr>
13.<td>
14.Name :
15.</td>
16.<td>
17.<html:text name="feedbackForm" property="name" />
18.</td>
19.</tr>
20.<tr>
21.<td>
22.Sex :
23.</td>
24.<td>
25.<html:radio name="feedbackForm" property="sex" value="M" >
26.M </html:radio>
27.<html:radio name="feedbackForm" property="sex" value="F" >
28.F </html:radio>
29.</td>
30.</tr>
31.<tr>
32.<td>
33.Comments :
34.</td>
35.<td>
36.<html:textarea cols="20" rows="5" name="feedbackForm"
37.property="comments" />
38.</td>
39.</tr>
40.<tr>
41.<td>
42.<html:submit />
43.</td>
44.<td>
45.<html:reset />
46.</td>
47.</tr>
48.</table>
49.</html:form>
50.</body>
51.</html>
The name attribute
of the HTML tag contains the Form Bean name. The property attribute of the HTML
Tag contains the corresponding Form property.
Once the feedback
is submitted by the user, the user will be forwarded to the success page. Here
the feedback submitted by the user will be displayed. We use Struts Bean Tag do
to this. We use Struts Logic Equal Tag to display Male if the user has selected
M for sex and Female if the user has selected F for sex. In order to use the
Struts Bean and Logic Tag you need to include the following taglib directives
in the jsp page.
1.<%@taglib
uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
2.<%@taglib
uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
The success.jsp
page contains the following code.
01.<%@taglib
uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
02.<%@taglib
uri="/WEB-INF/struts-logic.tld" prefix="logic" %>
03.<html>
04.<head>
05.<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
06.<title>Feedback Form</title>
07.</head>
08.<body>
09.<b>Feedback Successfully Submitted.</b>
10.
11.You have submitted
the following feedback.
12.<table>
13.<tr>
14.<td>
15.Name :
16.</td>
17.<td>
18.<bean:write name="feedbackForm" property="name" />
19.</td>
20.</tr>
21.<tr>
22.<td>
23.Sex :
24.</td>
25.<td>
26.<logic:equal name="feedbackForm" property="sex" value="M"> Male </logic:equal>
27.<logic:equal name="feedbackForm" property="sex" value="F"> Female </logic:equal>
28.</td>
29.</tr>
30.<tr>
31.<td>
32.Comments :
33.</td>
34.<td>
35.<bean:write name="feedbackForm" property="comments" />
36.</td>
37.</tr>
38.</table>
