public class JfreeChartAction extends ActionSupport {

public String execute() throws Exception {

donnees.setValue("Code",05);
donnees.setValue("Développement",02);
donnees.setValue("Tests",06);
donnees.setValue("Maintenance",01);
chart = ChartFactory.createPieChart3D(
"Répartition du typologiecarte", //titre
donnees, // données à afficher
true, // afficher la légende
true,
true
);
// créer le camembert
PiePlot3D plot=(PiePlot3D) chart.getPlot();
// angle d’affichage
plot.setStartAngle(190);
// rotation
plot.setDirection(Rotation.CLOCKWISE);
// transparence du schéma
plot.setForegroundAlpha(0.4f);
plot.setNoDataMessage("Pas de données à afficher");
return SUCCESS;
}
// getter pour retourner l’image
public JFreeChart getChart() {
return chart;

I don't know how to resolve it can anybody help me please?
problem occurs due to wrong return type declaration
return String is chart but no result found this name.
public String execute() { return "success"; }
now try it.
I solved my problem by adding a xwork-core-2.1.6.jar thanks to everyone makes effort to help me .
best regards

1) You have MySQL connection exception as below:
Establishing SSL connection without server's identity verification is not recommended.
According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set.
To resolve this use the connection string like below:(change the db name to your existing db name)
jdbc:mysql://localhost:3306/dbname?autoReconnect=true&useSSL=false
This needs to be sorted first, that's why the values of the variables are not been rendered
2) In the Latest trace the requested list key 'projectidList' could not be resolved as a collection/array/map/enumeration/iterator type.
This error occurs when you try to access a list/collection which haven't been created.
Try to initialize the collection objects List<String> projectidList at class level.
when particular action is triggered at that time, JSP page is not knowing the the type of field, in this case, when you write List<String> projectidList = new ArrayList<String>(); instead of this, change it to ArrayList projectidList = new ArrayList();.
Make sure that you access list after the action class is instantiated i.e. corresponding action is called.
If you want to directly access it before calling action make it static and access it inside jsp.
I am working on a dynamic Web Application and as a first step i want to use my jsf page to save a new Group in the DataBase .I am connecting to an Oracle 10g DataBase, working on eclipse Kepler, with Glassfish4 and using primefaces 4.0.This the StackTrace

This is the code of the managedBean
#ManagedBean
#ViewScoped
public class GroupeBean {
private Groupe newGroupe=new Groupe();
public Groupe getNewGroupe() {
return newGroupe;
}
public void setNewGroupe(Groupe newGroupe) {
this.newGroupe = newGroupe;
}
private DaoGroupe gdao= new DaoGroupe();
public void createGroupe()
{
gdao.ajouter(newGroupe);
}}
This is the code of the Dao Class
public class DaoGroupe {
private static final String JPA_UNIT_NAME="Portail";
private EntityManager entityManager;
protected EntityManager getEntityManager() {
if (entityManager == null) {
entityManager = Persistence.createEntityManagerFactory(
JPA_UNIT_NAME).createEntityManager();
}
return entityManager;
}
public void ajouter(Groupe g)
{
EntityTransaction tx = entityManager.getTransaction();
tx.begin();
entityManager.persist(g);
tx.commit();}}
And this is the insert tab in my jsf page
<p:tab title="Groupe">
<h:form>
<h:panelGrid columns="2">
<h:outputText value="Nom : *" />
<p:inputText value="#{groupeBean.newGroupe.nom}" required="true"
label="nomgrp" validatorMessage="Nom de Groupe Obligatoire" />
<h:outputText value="Numéro : *" />
<p:inputText value="#{groupeBean.newGroupe.idGroupe}" required="true"
label="numgrp" validatorMessage="Numéro de Groupe Obligatoire" />
</h:panelGrid>
<p:commandButton value="Ajouter"
style="width:205px;margin-left:10%"
action="#{groupeBean.createGroupe}" />
</h:form>
</p:tab>
You get a NullPointerException in your DaoGroupe-Class within the method ajouter.
I guess the entityManager.getTransaction() is the reason, because the entityManager is not filled anywhere. Replacing it with using your getEntityManager()-method might be a first point to start debugging from.
EntityTransaction tx = getEntityManager().getTransaction();
Hope it helps...

Please, could anyone help me?
Check if you have common-lang.jar of version 2.3 (as written by your link here: http://displaytag.sourceforge.net/11/displaytag/dependencies.html) otherwise browse if the jar has this class. If there is no class org.apache.commons.lang.UnhandledException in this jar you should download recommended version (http://commons.apache.org/proper/commons-lang/).

... You're throwing that exception, precisely where the stack trace tells you you are.
Are you unaware of Java stack traces? Are you unable to read the information it provides?
It's pointing to your code.
First of all defaultStack already includes fileUpload interceptor so you have to configure that interceptor instead of adding it twice to your action interceptors stack.
<action name="uploadAction" class="com.scrolls.fileupload.action.UploadImageAction" method="uploadImage">
<interceptor-ref name="defaultStack">
<param name="fileUpload.maximumSize">2097152</param>
<param name="fileUpload.allowedTypes">
image/png,image/gif,image/jpeg,image/pjpeg
</param>
</interceptor-ref>
<result name="success">ImageUploadSuccess.jsp</result>
<result name="input">index.jsp</result>
</action>
Second: in Struts2 you do not need to read submitted file from request. Read about file upload http://struts.apache.org/2.x/docs/file-upload.html.
You can try download example project from this link.

I have tried it already, it works.(thanks to the tutorial creator)
I am working on Struts2 Interceptors .
I have read that Struts2 Interceptors are just like Filters , which execute before the Action class is executed and one more time after processing the result ( Please correct me if i am wrong ) , that is two times
But when i ran the below code , the interceptors are executed only once .
Please correct me if i made any mistake .
Please see my code below :
This is My Struts.xml file
<struts>
<constant name="struts.devMode" value="true" />
<package name="test" extends="struts-default">
<interceptors>
<interceptor name="loginkiran" class="vaannila.MyLoginInterCeptor" />
</interceptors>
<action name="HelloWorld" class="vaannila.HelloWorld" method="kiran">
<interceptor-ref name="loginkiran" />
<result name="SUCCESS">/success.jsp</result>
</action>
</package>
</struts>
This is my Action class
public class HelloWorld
{
public HelloWorld() {
}
public String kiran() {
System.out.println("iNSIDE THE aCTION CLASS");
return "SUCCESS";
}
}
This is my Interceptor class
public class MyLoginInterCeptor implements Interceptor {
#Override
public void destroy() {
// TODO Auto-generated method stub
System.out.println("Destroying Interceptor");
}
#Override
public void init() {
}
#Override
public String intercept(ActionInvocation invocation) throws Exception {
HttpServletRequest request = (HttpServletRequest) ActionContext
.getContext().get(ServletActionContext.HTTP_REQUEST);
System.out.println("iNSIDE THE iNTERCEPTOR");
return invocation.invoke();
}
}
This is my JSP File :
<html>
<body>
<%
System.out.println("iNSIde THE jsp");
%>
</body>
</html>
The Output for the above code is this :
iNSIDE THE iNTERCEPTOR
iNSIDE THE aCTION CLASS
iNSIde THE jsp
Interceptors are not executed twice (nor are filters): interceptors (and filters) wrap the action (or servlet/etc.)
public String intercept(ActionInvocation invocation) throws Exception {
System.out.println("Before action invocation...");
return invocation.invoke();
System.out.println("After action invocation...");
}
