List of improvements:
1. new look with Bootstrap 3
2. add final/first page
3. no. of rows
List of softwares:
1. Bootstrap 3, http://getbootstrap.com/getting-started/
2. Previous example, http://www.oracle.com/webfolder/technetwork/tutorials/obe/java/JSFTablePagination/JSFTablePagination.html
Step:
1. Install jquery and bootstrap 3 libraries to Netbeans.
2. At jsf page, I created a new form (shown at the end).
3. At PaginationHelper, modify and add as follows:
public PaginationHelper(int pageSize, int page) {
this.pageSize = pageSize;
this.page=page;
}
//current page
public int getCurrentPage() {
return page;
}
public int getFinalPage(){
int count =getItemsCount();
return count % pageSize ==0 ? (count/pageSize)-1 : count/pageSize;
}
public void setFinalPages(){
this.page=getFinalPage();
}
4. At DvDLibraryBean, modify and add:
private int pageSize;
private int [] page;
//getter and setter
@PostConstruct
public void postConstruct() {
page =new int[]{5, 10,15,20,30, 50};
pageSize=10;
}
public PaginationHelper getPagination() {
if (pagination == null) {
pagination = new PaginationHelper(this.pageSize, 0) {
@Override
...
}
//go to the 1st page
public String firstPage() {
pagination=null; //reset pagination to null or setting to page=0;
recreateModel();
return "home";
}
//go to the last page
public String lastPage() {
getPagination().setFinalPages();
recreateModel();
return "home";
}
public String recreatePageSize(AjaxBehaviorEvent e) {
pagination=null;
recreateModel();
return "home";
}
5. Modify faces-config.xml with referring to list_Bootstrap.xhtml
Here are codes of list_Bootstrap.xhtml
