pagination in struts2
Are there any examples that show how to do pagination in struts2?
I would like to do pagination where we call the DB again when the user
clicks on one of the page numbers.

Lots of possibilities here:* you need to have a class named TestList in your
application
* you need a constructor for your TestList class that accepts an int and a
boolean as its arguments
* you need to be sure you are appropriate importing the reference to
TestList in your JSP

Re: pagination in struts2
Posted by denis cabasson <de...@gmail.com>.
Display tag is great for table pagination.
If you are looking for pagination without tables, I'd recommend the pager
tag library :
http://jsptags.com/tags/navigation/pager/index.jsp
Custom coding is my least favorite way of solving an issue.
To extract a variable from an action to the page, I'd recommend using a
s:set tag to set a variable holding the list in the page context.
Your example of displaytag is missing :
<s:set name="testList" scope="page" value="testList" id="testList"></s:set>
(before the display tag)

Re: pagination in struts2
Posted by Stefano Tranquillini <st...@gmail.com>.
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>">

</a>
</s:iterator>

Re: pagination in struts2
Posted by Andy Sykes <a....@ucl.ac.uk>.
I found I had to use the <s:set> tag to set the object in the request
scope before displaytag could "see" it, since displaytag doesn't know
about the Value Stack (maybe it should?). Confusingly, displaytag
gives you that message if it can't see the variable you're
referencing, as well as if the variable is empty.
eg. <s:set name="items" value="items" scope="request"/>

Re: pagination in struts2
Posted by Stefano Tranquillini <st...@gmail.com>.
i done this:
this is the class taht create the list
private List<Item> items = new ArrayList<Item>();
private Integer resultSize;
public AllItem() {
}
@Override
public String execute() throws Exception {
items= mgmt.getAllItem();
resultSize=getItems().size();
return SUCCESS;
}
public List<Item> getItems() {
return items;
}
public Integer getResultSize() {
return resultSize;
}
this is the page
<%@ taglib uri="/struts-tags" prefix="s" %>
<%@ taglib uri="http://displaytag.sf.net" prefix="display" %>
<display:table name="testList" pagesize="2" partialList="true"
size="resultSize">
<display:column property="name" />
<display:column property="descitipion" />
<display:column property="prize" />
</display:table>
the result is:
Nothing found to display.

It pays to really spend some time looking over existing documentation;
it's often quicker than waiting for someone on a list or forum to answer.

Re: pagination in struts2
Posted by Andy Sykes <a....@ucl.ac.uk>.
Have a look at the external sorting and pagination page[1] on the
DisplayTag site. Also, take a look at the PaginatedList interface[2].
It takes a little bit to get your head around it.
If you get stuck, the displaytag lists are pretty good at helping with
the common issues.
Andy.

Re: pagination in struts2
Posted by Bhaarat Sharma <bh...@gmail.com>.
jim,
I found this example
http://displaytag.homeip.net/displaytag-examples-1.2/example-paging.jsp?d-49653-p=1
it says "Ok, you have made a query that returns you back a list of 120
elements, but you don't want to show the user all 120 items at once, you
want to allow them to page through the results (pretend 120 is really 1200
or 12000)."
they are iterating through a long 12000 record list and then just putting
that into pages. What I was looking for was something that would show 50
results of 12000 on first page then when NEXT is cliked, it against goes to
DB to get next 50 records.

I found this within thirty seconds of clicking Dave's link:
http://displaytag.sourceforge.net/1.2/tut_sources.html
Note that the contents of this page are actually fairly freakin' horrible
and should not be done on a grownup application. But the instructions are
right there and easy to find.

then again I go to the DB to fetch next set of 50 records.

I'd suggest looking into DisplayTag (http://displaytag.sourceforge.net/)
