getting data in value object out of logic:iterate
I read the docs and looked through the examples and didn't see anything that
did what I was trying.
I have an array of Value(view) objects that I want to iterate through in my
jsp.
Here it is;
public class User
{
private String firstName;
private String lastName;
public String getFirstName() { return firstName; }
public void setFirstName(String firstName) { this.firstName =
firstName; }
public String getLastName() { return lastName; }
public void setLastName(String lastName) { this.lastName = lastName; }
...
}
public SomeAction extendsAction
{
perform(....
{
User[] users = new User[3];
users[0] = user1;
users[1] = user2;
...
request.setAttribute("users", Arrays.asList(users));
return mapping.findForward("something.jsp");
}
}
in the something.jsp
<TABLE>
<logic:iterate id="userList" name="?">
<TR>
<TD>
??? users.getFirstName(); ???
</TD>
<TD>
??? users.getLastName(); ???
</TD>
...
</TR>
</logic:iterate>
HELP!
thanks,
Michael Lee

You are very correct, there is a lot of 'chimp' like work in translating
value objects to forms to jsp tags to ApplicationResource.properties. I
spend lots of time double checking upper, lower case on stuff, simple
conversions (VO.setX(ActionForm.getX()) etc).
I'll have to check it out, thanks for the help!

Hi Michael,
You need:
<logic:iterate name="users" id="aUser">
<bean:write name="aUser" property="firstName"/>
<%-- etc --%>
</logic:iterate>
The name attr in logic:iterate must match the attribute name of the List.
Any BTW you're going to get really tired of writing Beans classes like
User. Many folks on this list are using the DynaBean framework. Also
let me plug my own project, dynclass.sourceforge.net, which will
transform an arbitrary java Map into a JavaBean...
