Hello,
Well, I will put all my code, because I have an error I can't found (since 2
days !!! )
First, here is my form :
| <jbpm:datacell>
|
| <f:facet name="header">
| <h:outputText value="Produit desire: "/>
| </f:facet>
|
| <h:selectOneMenu value="#{genList.value}">
| <f:selectItems value="#{genList.items}" />
| </h:selectOneMenu>
|
| </jbpm:datacell>
|
Here is my genList.java :
| public class genList {
|
| private String value="";
| private Connection conn;
|
| public genList() {}
|
| public String getValue() {
| return value;
| }
| public void setValue(String value) {
| this.value = value;
| }
|
| public Collection getItems() {
|
| Collection items = new ArrayList();
| SelectItem si = null;
|
| try{
| //-- Connexion
| Class.forName("com.mysql.jdbc.Driver");
| conn = DriverManager.getConnection
("jdbc:mysql://localhost:3306/databaseName", "root", " ");
|
| //-- Creation du statement et de la requete
| Statement stmt = conn.createStatement();
| String requete = null;
| requete = "SELECT ID_,NOM_ FROM materiel";
|
| //-- Execution de la requete
| ResultSet rs = stmt.executeQuery(requete);
|
| //-- Lecture des donnees
| while (rs.next())
| {
| si = new SelectItem (String.valueOf(rs.getInt(1)),
rs.getString(2));
| items.add(si);
| }
|
| //-- Deconnexion
| conn.close();
| } catch(Exception e){
| System.out.println("\n\n\nCONNEXION ECHOUEE: "+e+"\n\n\n");
| System.exit(-1);
| }
|
| return items;
| }
| }
|
And finally here is my Face Config :
| <managed-bean>
| <managed-bean-name>genList</managed-bean-name>
| <managed-bean-class>com.demande.action.genList</managed-bean-class>
| <managed-bean-scope>request</managed-bean-scope>
| </managed-bean>
|
When I want to start my process I always have this error :
Argument Error: An option for component j_id48 was not an instance of
javax.faces.model.SelectItem. Type found: java.util.ArrayList.
(j_id48 is the name given automatically to the combo box)
I tried a lot of things to repair that error, but nothing works... I can't see
where is the problem, if you could help me, I will be very happy !
Thanks,
