hi,
I am a newbie to Apache Struts. I'd like to know what a good Struts application
looks like.
In our JSP pages, should we try to avoid embedded java code but use tags?
For example, i have an index.jsp page for my banking application.
When a user comes to this page, it displays the login form. When a user has
already logged
in, it displays the user's account list. The user information is saved in the
session as
an instance of my User class. I wrote my index.jsp as the following:
<%
User user = (User)session.getAttribute("USER");
if (user==null) {
%>
<html:form action="Login">
Login Name: <html:text property="loginName" size="16"/><br/>
Password : <html:password property="password" size="16"/><br/>
</html:form>
<%
} else {
Iterator iter = Account.getAccountList(user);
int count = 0;
while (iter.hasNext()) {
count ++;
Account account = (Account)iter.next();
%>
<%= account.getName() %>
(created on <%= account.getCreatedDate() %>)<br/>
<%
}
%>
Total <%= count %> accounts found.<br/>
<%
}
%>
Here are my questions:
1. My business object is the Account class. It provides
a static method getAccountList(User user) to get an iterator
of all the accounts of the given user. I am calling this method directly
in my index.jsp file, but it does not seem to be a good struts programming
style. So what is the preferred way for doing this?
2. I used embedded java code for checking whether a user has logged in.
Should i use tags in the bean taglib or logic taglib to get an object from
the session and check it?
Thanks for any reply.
