The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Working with JSF Tables (com.webui.jsf.component.Table) and Lists using ObjectListDataProvider for Sorting, Paging, and Memorizing Position

Asked by jboss79 in Java Server Faces (JSF), Java Server Pages (JSP), Java Servlets

My problem is that I am trying to handle JSF tables with the following functionality:
1. Sortable Column Headers
2. Paging
3. Clicking on a record to navigate to another page (detail page) and then return to the same position in the table when saving or cancelling out of that page.

I've tried using standard JSF components and found no paging support. I then switched to MyFaces and found it clumsy and poorly documented. I finally switched to the Sun JSF components available in NetBeans Visual WebPack. It handles paging very nicely, but doesn't work for sorting. I also haven't figured out how to leave my list to go to a detail and get back to the same place.

The code below accomplishes paging, but I have not figured out sorting or leaving and returning to the same place.  I don't want to tie the table directly to a DB table, but rather to a list of objects. I've included relevant code:

//init() method of the JSF Page
List<User> list = getOYSessionBean().getUserList();
        if(list == null || list.size()<=0){
            FacesContext context = FacesContext.getCurrentInstance();
            HttpSession session = (HttpSession) context.getExternalContext().getSession(false);
            UserBean loginuser = (UserBean)session.getAttribute("LoginUserBean");
            if(loginuser!=null){
                User_Manager um = new User_Manager();
                um.setPubServerConnection(loginuser.getPubServerConnection());
                um.setServerConfig(loginuser.getServerUtility());
               
                if(um.readDBUsers(loginuser)==0) list = um.getUserList();
                getOYSessionBean().setUserList(list);
            }
        }
        getDpUserList().setList(list);

JSF Components used:
import com.sun.webui.jsf.component.Table;
import com.sun.webui.jsf.component.TableColumn;
import com.sun.webui.jsf.component.TableRowGroup;
import com.sun.data.provider.impl.ObjectListDataProvider;

Any support would be greatly appreciated. I've been reading tutorial after tutorial on the net, but have found minimal support for interacting with these components using Lists.

Thanks
