i've done a pagination by myself.
is an Alpha relase :D, not tested but u can set size and page to display:
action:
private List<Item> items = new ArrayList<Item>();
private int tot;
private int page = 0;
private int size = 1;
private List pages = new ArrayList();
public AllItem() {
}
@Override
public String execute() throws Exception {
List<Item> temp = mgmt.getAllItem();
if (page > 0) {
page--;
}
if (size > temp.size()) {
size = temp.size();
}
int start = Math.min(page * size, temp.size());
if (start == temp.size()) {
start = start - size;
}
int end = Math.min((page + 1) * size, temp.size());
items = new ArrayList<Item>();
items = temp.subList(start, end);
tot = getItems().size();
pages = new ArrayList();
for (int i = 0; i < temp.size(); i = i + size) {
pages.add((i / size) + 1);
}
return SUCCESS;
}
public List<Item> getItems() {
return items;
}
public int getTot() {
return tot;
}
public int getPage() {
return page;
}
public void setPage(int page) {
this.page = page;
}
public int getSize() {
return size;
}
public void setSize(int size) {
this.size = size;
}
public List getPages() {
return pages;
}
jsp
<%@ taglib uri="/struts-tags" prefix="s" %>
<s:iterator value="items" >
do your presentation of the data
</s:iterator>
this is the menu change the action!
<s:iterator value="pages" >
<a href="<s:url action="showShop" namespace="/shop">
<s:param name="page">
<s:property/>
</s:param>
<s:param name="size" value="%{size}"/>
</s:url>">
<s:property/>
</a>
</s:iterator>
