I’m working on JSF1.2 + EJB3.0 + Websphere 7.0.0.3. The whole business logic layer and Data layer (EJB 3.0) are tested and work successfully from the beginning. After I integrated JSF1.2, I got these errors when I tried to get some data from database:

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.

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;
    }
}

I’m quite sure that this error might come from my stupid mistake but I couldn’t figure it out. Can someone help me out?

Just replace

value="#{modelRootBean.getCustomers}"

with

value="#{modelRootBean.customers}"
