How to use hashmap in logic:iterate/

Question

Now i want to display four list columns within a table.
example:
<logic:iterate name="rowSet" property="hashMap" id="rowSetObj">
<tr>
<td><bean:write name="rowSetObj" property="v1"></td>
<td><bean:write name="rowSetObj" property="v2"></td>
<td><bean:write name="rowSetObj" property="v3"></td>
<td><bean:write name="rowSetObj" property="v4"></td>
</tr>
</logic:iterate>
Can you help me?
how do i need to make a java bean about rowSet and rowSetObj?

Answer 1

Hi,
You need to make bean like:
public class YourClass {
public someType getV1() {return somthing}
Then as you need iteration you have to create array, or collection or something described in http://jakarta.apache.org/struts/userGuide/dev_logic.html
and fill it with instances of YourClass
Then you need to add this that something into session like this:
session.setAttribute(SESSION_ATTRIBUTE_NAME, yourArray);
And then in your JSP you can do as you wrote, but you have to add one more attribute: type. so, you will have:
<logic:iterate name="rowSet" property="hashMap" id="rowSetObj"
type yourPackage.YourClass scope="session">
<tr>
<td><bean:write name="rowSetObj" property="v1"></td>
<td><bean:write name="rowSetObj" property="v2"></td>
<td><bean:write name="rowSetObj" property="v3"></td>
<td><bean:write name="rowSetObj" property="v4"></td>
</tr>
</logic:iterate>
good luck
if i'm write it should work :)
