Part II: Create Weblog UI - A HowTo for creating a UI (in Struts) for managing the DAOs created in the Hibernate Relationships tutorial. I've eliminated creating managers in this tutorial for a couple reasons: 1) to reduce the amount of code and 2) to show you that you don't have to create them.

About this Tutorial

In this section, you'll create a UI that has the following features.

Create a Weblog
View Weblog and its Entries
Add a New Entry
Edit/Save an existing Entry
Edit a Weblog and its Users
Edit a User and their Weblogs

[1] Modify userForm.jsp to allow creating/editing a weblog (many-to-many)
[2] Modify the UserAction to support editing a user's weblogs
[3] Create an EntryAction to handle CRUD-ing Entries
[4] Add the ability to see all Weblogs and edit them, as well as their users

Modify userForm.jsp to allow creating/editing a weblog [#1]

A weblog record has 4 fields: weblogId, username, blogTitle and dateCreated. The blogTitle is the only field that users should be able to edit. The rest of them can be set programmatically. Open web/pages/userForm.jsp and add the following code to the bottom of the form (between </table> and </form>.

<fieldset style="position: absolute; top: 190px; left: 520px">
    <legend style="font-weight: bold">Weblogs</legend>
    <c:forEach var="blog" items="${userForm.weblogs}" varStatus="index">
        <input type="hidden" name="weblogs[<c:out value='${index.index}'/>].weblogId" value="<c:out value='${blog.weblogId}'/>"/>
        <input type="hidden" name="weblogs[<c:out value='${index.index}'/>].username" value="<c:out value='${blog.username}'/>"/>
        <input type="hidden" name="weblogs[<c:out value='${index.index}'/>].dateCreated" 
           value="<fmt:formatDate value='${blog.dateCreated}' pattern="MM/dd/yyyy"/>"/>
        <input type="text" name="weblogs[<c:out value='${index.index}'/>].blogTitle" size="40" value="<c:out value='${blog.blogTitle}'/>"/><br/>
    </c:forEach>

</fieldset>

If you run "ant deploy", go to http://localhost:8080/appfuse/editProfile.html and login as "tomcat/tomcat", you should see a screenshot like the one below:
