Re: struts help using logic:iterate
Hien,
Thank you for replying to my message. I will try this way. Since I'm new
on Struts, I thought there would be some other tag other than logic:iterate
tag to do the trick. Btw, I'm running weblogic 7.0 sp4. Do you know if it
supports JSTL?

Re: struts help using logic:iterate
If you make your Item class returns an Error object, you can avoid the
errorCodeList, something like this:
public class Item {
private int id=0;
private MyError error;
/**
* @return Returns the error.
*/
public MyError getError() {
return error;
}
/**
* @param error The error to set.
*/
public void setError(MyError error) {
this.error = error;
}
/**
* @return Returns the id.
*/
public int getId() {
return id;
}
/**
* @param id The id to set.
*/
public void setId(int id) {
this.id = id;
}
/**
* @param id
*/
public Item(int id) {
super();
this.id = id;
}
}
assume that you have MyError class defined as a JavaBean with two
properties errorCode (int) and errorString (String).
in your jsp:
<%
java.util.Collection itemList = new java.util.ArrayList();
hqn.Item item1 = new hqn.Item(1);
item1.setError( new hqn.MyError(1, "Error Description 1") );
itemList.add( item1 );
hqn.Item item2 = new hqn.Item(2);
item2.setError( new hqn.MyError(2, "Error Description 2") );
request.setAttribute("itemList", itemList );
%>
Using JSTL forEach tag:
Item ID=
Error Code:
Error Desc:
Using logic:iterate tag:
Item Id=
Error Code:
Error Desc:
I'd recommend you to use JSTL.

I have two Arraylist call itemList and errorCodeList. The itemList
contains list of Item object. The item object has a property calls
errorCode which returns an error code in int (1-50). I want to
display the error description associates to that error code. How can
I pass in the error code to the errorCodeList the get the error
description.
Item Error Description

struts help using logic:iterate
I'm very new to struts so please be kindly. I have two Arraylist call itemList and errorCodeList. The itemList contains list of Item object. The item object has a property calls errorCode which returns an error code in int (1-50). I want to display the error description associates to that error code. How can I pass in the error code to the errorCodeList the get the error description. Item Error Description - item1description1 item2description2 item3description1 .. ..
