Ich arbeite an JSF1.2 + EJB3.0 + WebSphere 7.0.0.3. Die gesamte Geschäftslogikschicht und die Datenschicht (EJB 3.0) werden von Anfang an getestet und funktionieren erfolgreich. Nachdem ich JSF1.2 integriert hatte, habe ich diese Fehler erhalten, als ich versuchte, einige Daten aus der Datenbank zu erhalten:
E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E: Uncaught exception created in one of the service methods of the servlet Faces Servlet in application de.rwth.swc.ejb.generator.prototype.muster.ear. Exception created : javax.servlet.ServletException: /modelroot.jsp(19,5) '#{modelRootBean.getCustomers}' The class 'de.rwth.swc.ejb.generator.prototype.muster.client.backingbeans.ModelRootBean' does not have the property 'getCustomers'.

Modelrootbean (BackingBean)
package de.rwth.swc.ejb.generator.prototype.muster.client.backingbeans;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
import javax.ejb.EJB;
import de.rwth.swc.ejb.generator.prototype.muster.controller.ModelRootControllerBean;
import de.rwth.swc.ejb.generator.prototype.muster.domain.Contract;
import de.rwth.swc.ejb.generator.prototype.muster.domain.Customer;
public class ModelRootBean implements Serializable{
private List<Customer> customers;
private List<Contract> contracts;
@EJB
private ModelRootControllerBean modelRootControllerBean;
public ModelRootBean() {
customers = new ArrayList<Customer>();
contracts = new ArrayList<Contract>();
}
public List<Customer> getCustomers() {
customers = modelRootControllerBean.getAllCustomer();
}
public void setCustomers(List<Customer> customers) {
this.customers = customers;
}
public List<Contract> getContracts() {
//contracts = modelRootControllerBean.getAllContracts();
return contracts;
}
public void setContracts(List<Contract> contracts) {
this.contracts = contracts;
}
}
Ich bin mir ziemlich sicher, dass dieser Fehler aus meinem dummen Fehler zurückzuführen sein könnte, aber ich konnte es nicht herausfinden. Kann mir jemand helfen?
Lösung
Einfach ersetzen
value="#{modelRootBean.getCustomers}"
mit
value="#{modelRootBean.customers}"
Andere Tipps
Verwenden modelRootBean.customers Anstatt von modelRootBean.getCustomers.
ManagedBean Properties müssen ohne "Get" -Präfix in JSF aufgerufen werden.
