I've been searching here for hour now and unfortunately I can't how to display database records to datatable, I'm newbie to JSF and I don't know much on JSF right now but I'm building a simple crud application I already know how to create, delete records using JSF but I'm having problem displaying this records to my datatable. I tried creating arraylist, I tried creating another class for this, To make it more clear here is my code:
This is my index.jsf:

I don't have any error or something and it display only the last records in the database. Guys if you know the easiest ways can you teach me how to do it, and I always go for a nice clean, short code. your help is really much appreciated :)
There is a bug in your displayTableRecords() method. Within while loop you instantiate new TableUser array for each iteration. Actually what you should do is add TableUser object one by one to existing array.
Use ArrayList inseadof array.
private List<TableUser> tableRs = new ArrayList<TableUser>();
public List<TableUser> getTableRs() {
return tableRs;
}
public void setTableRs(List<TableUser> tableRs) {
this.tableRs = tableRs;
}
private void displayTableRecords() {
String query = "SELECT * FROM USERS";
PreparedStatement state = con.prepareStatement(query);
state.execute();
rs = state.getResultSet();
while (rs.next()) {
tableRs.add(new TableUser(rs.getLong(1),
rs.getString(2), rs.getString(7), rs.getString(5)));
}
}

The fields must be likeThis instead of LikeThis. Just change your JSF code to
<h:dataTable value="#{pretechDataTableBean.user}" var="user">
<h:column>
<f:facet name="header">Name</f:facet>
#{user.fName}
</h:column>
<h:column>
<f:facet name="header">Email</f:facet>
#{user.email}
</h:column>
<h:column>
<f:facet name="header">Password</f:facet>
#{user.pwd}
</h:column>
</h:dataTable>
And update the field names in your User class to follow the proper Java Bean naming convention.
public class users implements java.io.Serializable {
private long userId;
private String fName;
private String lName;
private long userTypeId;
private String userName;
private String email;
private String pwd;
private String note;
private boolean isActive;
//constructor, getters and setters
}
Apart from this, there are other bugs in your current design:
You must not have business logic in the getters of your managed bean, instead take advantage of the #PostConstruct method to initialize the necessary data to be used.
Since this bean looks that should stay alive while the user stays in the same view, it will be better to decorate it as #ViewScoped instead of #RequestScoped.
Use proper names for your classes and fields. For example, if you have a List<Something> field, name your variable somethingList or similar in order that the code is self-explanatory.
From these, you can change your managed bean to:
#ManagedBean
#ViewScoped
public class PretechDataTableBean {
private List<users> userList;
public PretechDataTableBean() {
}
#PostConstruct
public void init() {
Session session = HibernateUtil.getSessionFactory().openSession();
Transaction transaction = null;
List<users> users =null;
try
{
transaction = session.beginTransaction();
users = session.createQuery("from users").list();
}
catch(Exception e)
{
e.printStackTrace();
}
finally{
session.close();
}
return users;
}
public List<users> getUserList() {
return this.user;
}
}
Since the field changed its name in the managed bean, you should edit it accordingly in the respective view:
<h:dataTable value="#{pretechDataTableBean.userList}" var="user">

I am getting the following error :
Unable to find matching navigation case with from-view-id '/index.xhtml' for action '#{medcontroller.getMedGeneric}' with outcome 'javax.faces.model.ListDataModel#7a652236'
I am new to jsf and I'm really clueless about solving this error. I have a ManagedBean with the following code:

}
public MedController(int startId, int endId) {

}
public Medicine getSelected() {

}
return medNames;
}
void recreateModel() {

}
public boolean isHasNextPage() {

return pageSize;
}
public String prepareView(){
current = (Medicine) getMedNames().getRowData();

Please help me solve the error.
Also, I do not have a faces-config.xml file. I am using netbeans ide 7.1.2 web application with jsf and hibernate framework.
Thank you in advance.
The <h:commandButton action> must point to a method which invokes some business logic and returns either void or a String representing the target page you'd like to (re)display. However you returned a whole ListDataModel which isn't making any sense to JSF navigation handler and hence this error.
Something like this should do:
public String getMedGeneric(){
// Do your business logic here.
return "someViewId";
}
This will navigate to someViewId.xhtml. However, if you intend to stick on the same view, just let it return void (or null) and it will redisplay the same view.
public void getMedGeneric(){
// Do your business logic here.
}
By the way, it's really a poor naming convention to prefix action method names with get. This is confusing and makes your code not self-documenting. Rather name it loadMedGeneric() or so. I'm merely guessing as you didn't tell anywhere about the concrete functional requirement, what exactly that button should be doing.
getMedGeneric should return java.lang.String which represent navigation to another page described in faces-config.xml. In your case it return some model so it will not work unfortunatell. Let try to put getMedGeneric() action to actionListener and then in action put navigation String. i.e:
action="navString" actionListener="#{medcontroller.getMedGeneric}"
you should try just
actionListener="#{medcontroller.getMedGeneric}"

}
i'm getting this error:
javax.faces.FacesException: DataModel must implement
org.primefaces.model.SelectableDataModel when selection is enabled.....
just add this attribute rowKey to the datatable tag :
<p:dataTable border="1" value="#{projectAdminisrationMB.projectNoUsersList}"
var="userObj"
rowKey="#{userObj.name}"selection="#{projectAdminisrationMB.selectedUsers}"
selectionMode="multiple" rowIndexVar="rowIndex"
binding="#{table2}">
You can get this error if you try to add a new item to the underlying list and forget to assign a value to that new item's rowKey.
Alternatively to rowKey you can wrap your data in a custom model which really implements org.primefaces.model.SelectableDataModel. This is helpful if
all of your your classes have the same kind of #Id (e.g. a long) and can implement the same interface (e.g. EjbWithId)
you want to add additional functionalities to your data which are not domain specific and don't belong e.g. User.
The interface may be something like this:
public interface EjbWithId
{
public long getId();
public void setId(long id);
}
Then a generic implementation of SelectableDataModel for all your classes can be used:
public class PrimefacesEjbIdDataModel <T extends EjbWithId>
extends ListDataModel<T> implements SelectableDataModel<T>
{
public PrimefacesEjbIdDataModel(List<T> data)
{
super(data);
}
#Override public T getRowData(String rowKey)
{
List<T> list = (List<T>) getWrappedData();
for(T ejb : list)
{
if(ejb.getId()==(new Integer(rowKey))){return ejb;}
}
return null;
}
#Override public Object getRowKey(T item) {return item.getId();}
}
In your #ManagedBean:
private PrimefacesEjbIdDataModel<User> dmUser; //+getter
dmUser = new PrimefacesEjbIdDataModel<User>(administrationProjectFinal.getUserList());
first check whether you've added
rowKey="#{userObj.id}"
then you need to have the data table List set in filteredValue attribute of your data table in xhtml, instead of value.
I have a simple page where a I use <ui:repeat> and it gets the value from a backing bean.
The initial request will give it an empty list. The postback then will invoke an action that will change the model behind the <ui:repeat> but it is not rendered?!
I debugged through it and I saw that the <ui:repeat> evaluates the value at restore view phase but thats it. When it reaches render response it does not use the latest value from my bean. Is that the expected behavior?
How can I make that work? Do I have to write my own repeat tag?
I can't really tell what could be the problem without some of your code, but these are the basics:
Backing bean:
public class ObjectService{
private DataModel objectDataModel;
private List<Object> objectList;
private Pagination paginationHelper;
private ObjectDao objectDao = new ObjectDao();
private String queryOption;
public void setQueryOption(String queryOption){
