Listing 5–2 simple/src/java/com/corejsf/Name.java
1. package com.corejsf;
2.
3. public class Name {
4. private String first;
5. private String last;
6.
7. public Name(String first, String last) {
8. this.first = first;
9. this.last = last;
10. }
12. public void setFirst(String newValue) { first
13. public String getFirst() { return first; }
14.
15. public void setLast(String newValue) { last
16. public String getLast() { return last; }
17. }
Listing 5–3 simple/src/java/com/corejsf/TableData.
1. package com.corejsf;
2.
3. public class TableData {
4. private static final Name[] names = new Name[]
5. new Name("William", "Dupont"),
6. new Name("Anna", "Keeney"),
7. new Name("Mariko", "Randor"),
8. new Name("John", "Wilson")
9. };
10.
11. public Name[] getNames() { return names;}
12. }
NOTE:
The value attribute represents the data over which h:dataTable iterates; that data
must be one of the following:
• A Java object
• An array
• An instance of java.util.List
• An instance of java.sql.ResultSet
• An instance of javax.servlet.jsp.jstl.sql.Result
• An instance of javax.faces.model.DataModel
