Tutoriel JSF, Spring et Hibernate

Bonjour,

Je suis le tutoriel de Alexis Hassler "Tutoriel JSF, Spring et Hibernate" et j'en suis à l'étape de JSF.

Lorsque je lance courselist.jsf dans le navigateur j'obtiens l'erreur suivante :

Citation:

Voici mon courselist.jsf :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 <rich:scrollableDataTable id="courseTable" binding="#{courseBean.courseTable}" value="#{courseBean.courseList}" var="course" width="300px" height="200px"> <%-- <a4j:support event="onRowDblClick" <%-- action="#{courseBean.viewDetail}" --%> /> --%> <rich:column id="code" width="60px"> <f:facet name="header"> <h:outputText value="Code" /> </f:facet> <h:outputText value="#{course.code}" /> </rich:column> <rich:column id="name" width="200px"> <f:facet name="header"> <h:outputText value="Nom" /> </f:facet> <h:outputText value="#{course.name}" /> </rich:column> <rich:column id="length" width="60px"> <f:facet name="header"> <h:outputText value="Longueur" /> </f:facet> <h:outputText value="#{course.length}" /> </rich:column> </rich:scrollableDataTable>
Et le coursebean.java
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 public class CourseBean implements Serializable { @Autowired private transient courseService courseService; private transient HtmlScrollableDataTable courseTable; private List<Course> courseList; private Course currentCourse; @PostConstruct public void init() { courseList = courseService.findAll(); } public String update() { courseService.save(currentCourse); init(); return null; } public HtmlScrollableDataTable getCourseTable() { return courseTable; } public void setCourseTable(HtmlScrollableDataTable courseTable) { this.courseTable = courseTable; } public List<Course> getCourseList() { return courseList; } public void setCourseList(List<Course> courseList) { this.courseList = courseList; } public Course getCurrentCourse() { return currentCourse; } public void setCurrentCourse(Course currentCourse) { this.currentCourse = currentCourse; } }
Quelqu'un saurait-il m'expliquer d'où peut venir l'erreur ?

Merci d'avance pour votre aide.

soit tu changes ton id="", car cette erreur apparait lorsque tu essaie de mettre dans un binding une proprieté de type String, appremment il doit le confondre a ton id.

essaie en remplacant tes #{ par des ${

j'ai contourné à ce probleme en mettant le code suivant :

<rich:scrollableDataTable
value="#{courseBean.getCourseList()}"
var="course" width="300px" >

mais je recois une table vive ,ce qui vaut dire que mnt j'ai un probleme dans mon fichier application-context.xml :

<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
<bean id="courseService" class="Service.CourseServiceImpl">
</bean>

<bean id="courseBean" class="Web.CourseBean" scope="session">
<property name="service">
<ref bean="courseService"/>
</property>
</bean>

eclipse m'affiche l'erreur suivante :

Error creating bean with name 'courseBean' defined in ServletContext resource [/WEB-INF/application-context.xml]: Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException: Invalid property 'service' of bean class [Web.CourseBean]: Bean property 'service' is not writable or has an invalid setter method. Does the parameter type of the setter match the return type of the getter?

ton bean n'a pas de propriété appelée "service", en tout cas pas d'après spring ni d'après le code que tu nous a montré plus haut.
