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:
<c:forEach items="${itemList}" var="item">
Item ID= <c:out value="${item.id}"/><BR>
Error Code: <c:out value="${item.error.errorCode}"/><BR>
Error Desc: <c:out value="${item.error.errorString}"/><BR>
</c:forEach>Using logic:iterate tag:
<logic:iterate id="item" name="itemList">
Item Id= <bean:write name="item" property="id"/><BR>
<bean:define id="error" name="item" property="error"/>
Error Code: <bean:write name="error" property="errorCode"/><BR>
Error Desc: <bean:write name="error" property="errorString"/><BR>
</logic:iterate>I'd recommend you to use JSTL.

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 -------- ------------------------- item1 description1 item2 description2 item3 description1 . . . .
