Here is the screen shot when i run the application .

Looks like the MySQL driver can't be found. Some things to check:
Has the driver JAR been deployed to the serverlet container or
application server?
Have the connection details been verified through
the container console?

How to populate the dropdown list using <s:select> tag and hibernate in?

I am working on a project using Struts2 and Hibernate. After employees successfully log on, they will be brought to a new page displaying an event list. This list will be a dropdown select list. I have successfully written and tested my code for logon part, but when I add the second jsp page with tag, they show me the following exception:
message tag 'select', field 'list', name 'yourEvent': The requested list key 'events' could not be resolved as a collection/array/map/enumeration/iterator type. Example: people or people.{name} - [unknown location]
description The server encountered an internal error that prevented it from fulfilling this request.

This is an Hibernate problem. The entity has fields declared to be lazy loaded but the entity is not attached to a valid Hibernate Session to fire the proxies to retrieve the data lazily. From the stacktrace, I cannot be sure if this error is thrown by e.getSalaire().getPersonnel().getCin() or .getSalaire().getMois().getMois() (or maybe both).
I don't know how you configured the session management, probably Spring is handling it. To solve this, you should re attach the entity to a valid Hibernate Session. You can do this by using HibernateTemplate#refresh method from the Spring Hibernate integration classes.

Primefaces -> DataTable - Lazy Loading

I have a problem with DataTable - Lazy Loading. I think the problem is in IdiomasBean.java (the equilavent to TableBean.java), if I put:
public IdiomasBean() { }
public LazyDataModel<Idiomas> getLazyModel() {
lazyModel = new LazyIdiomasDataModel(idiomasBo.findAllIdiomas());
return lazyModel;
}
I get the datatable right, but... sortBy, filterBy and onRowSelect don't work.
public IdiomasBean() {
lazyModel = new LazyIdiomasDataModel(idiomasList);
}
public LazyDataModel<Idiomas> getLazyModel() {
return lazyModel;
}
I get: java.lang.NullPointerException

Does anybody have any solution?
Thanks!

Try this for your LazySorter class should fix the sort by not working
public class LazySorter implements Comparator<Idiomas> {
private String sortField;
private SortOrder sortOrder;
/**
* initializing sorting field and sorting order
* #param sortField
* #param sortOrder
*/
public LazySorter(String sortField, SortOrder sortOrder) {
this.sortField = sortField;
this.sortOrder = sortOrder;
}
/**
* Comparing object1 and object2 with reflection
* #param object1
* #param object2
* #return
*/
#Override
public int compare(Idiomas object1, Idiomas object2) {
try {
Field field1 = object1.getClass().getDeclaredField(this.sortField);
Field field2 = object2.getClass().getDeclaredField(this.sortField);
field1.setAccessible(true);
field2.setAccessible(true);
Object value1 = field1.get(object1);
Object value2 = field2.get(object2);
int value = ((Comparable)value1).compareTo(value2);
return SortOrder.ASCENDING.equals(sortOrder) ? value : -1 * value;
}
catch(Exception e) {
throw new RuntimeException();
}
}
}
