Question

我正在使用带有MySQL的openxava 4.7.1。我做了所有正确的配置并定义了我的pojos，例如

package com.iserve.ticketmanager;

import java.util.*;
import javax.persistence.*;
import org.openxava.annotations.*;

@Entity
public class Party {

    @Id
    @Required
    @Column(name = "id", nullable = true)
    private Integer id;

    @Column(name = "name", length = 45, nullable = true)
    private String name;

    @Column(name = "manager", nullable = true)
    private Integer manager;

    @Stereotype("IMAGE")
    @Column(name = "logo", nullable = true)
    private String logo;

    @Column(name = "active", length = 0, nullable = true)
    private Boolean active;

    @OneToMany
    private Set<Payment> payment;

    @OneToMany
    private Set<User> user;

    public void setPayment(Set<Payment> aValue) {
        payment = aValue;
    }

    public Set<Payment> getPayment() {
        return payment;
    }

    public void setUser(Set<User> aValue) {
        user = aValue;
    }

    public Set<User> getUser() {
        return user;
    }

    public void setTicketsale(Set<Ticketsale> aValue) {
        ticketsale = aValue;

    }

    public void setInventory(Set<Inventory> aValue) {

    }

    public Set<Inventory> getInventory() {
        return inventory;
    }

    public void setTicketredeem(Set<Ticketredeem> aValue) {
        ticketredeem = aValue;
    }

    public Set<Ticketredeem> getTicketredeem() {

        ticket = aValue;

    public Set<Ticket> getTicket() {
        return ticket;
    }

    public void setShipment(Set<Shipment> aValue) {
        shipment = aValue;
    }

    public Set<Shipment> getShipment() {

    }

    public void setTicketbatch(Set<Ticketbatch> aValue) {
        ticketbatch = aValue;

    }

    public Set<Vendororder> getVendororder() {
        return vendororder;
    }
}

我通过在openxava发行版中启动tomcat来启动应用程序。当我尝试访问任何模块时，在所有情况下都会出现与此类似的错误 -

可能会发生什么？

Answer 1

我怀疑你在URL中使用小写字母作为实体的第一个字母。以这种方式尝试URL：

http://localhost:8080/YourApplication/modules/Party

您的应用和派对案例必须正确。

为什么OpenXava不能识别我的Pojo？
