我们有一个应用程序，它在服务器（jboss.4.2.1.GA）端有一个swing客户端和java应用程序。我们正在使用ejb3。在我们的应用程序中，我们成功地创建了发票并将其显示给用户，但是当用户想要更改发票时，我们会收到以下错误。重新加载发票后，用户可以更改发票而不会出现任何错误。发票创建代码、发票更改和完整错误堆栈如下：

public Invoice createInvoice(String invoiceNo, CreateInvoiceGroupTemplate template, Collection serviceCalculations)
        throws Exception
{
    manager.setFlushMode(FlushModeType.COMMIT);

    if (glDao.isInvoiceNoInUse(manager, invoiceNo))
        throw new NonUniqueInvoiceNoException(invoiceNo);

    Invoice invoice = new Invoice();
    invoice.setNo(invoiceNo);
    invoice.setInvoiceDate(template.getMinimumInvoiceDate());
    Date paymentDay = findInvoicePaymentDay(template);
    invoice.setPaymentDate(paymentDay);
    invoice.setFormBeginDate(template.getFormBeginDate());
    invoice.setFormEndDate(template.getFormEndDate());

    Currency currency = new Currency();
    currency.setId(template.getCurrencyId());
    invoice.setCurrency((Currency) dao.findByPrimaryKey(manager, currency));

    Customer customer = new Customer();
    customer.setId(template.getCustomerId());
    invoice.setCustomer((Customer) dao.findByPrimaryKey(manager, customer));

    if (template.getRepresentativeId() > 0)
    {
        Representative representative = new Representative();
        representative.setId(template.getRepresentativeId());
        invoice.setRepresentative((Representative) dao.findByPrimaryKey(manager, representative));
    }

    if (template.getAccountingGroupId() != 0)
    {
        AccountingGroup accountingGroup = new AccountingGroup();
        accountingGroup.setId(template.getAccountingGroupId());
        invoice.setAccountingGroup((AccountingGroup) dao.findByPrimaryKey(manager, accountingGroup));
    }

    if (template.getAirlineGroupId() > 0)
    {
        AirlineGroup airlineGroup = new AirlineGroup();
        airlineGroup.setId(template.getAirlineGroupId());
        invoice.setAirlineGroup((AirlineGroup) dao.findByPrimaryKey(manager, airlineGroup));
    }

    if (template.getAirportId() != 0)
    {
        Airport airport = new Airport();
        airport.setId(template.getAirportId());
        invoice.setAirport((Airport) dao.findByPrimaryKey(manager, airport));
    }

    //automatically create new address based on the last invoice for this customer and representative
    InvoiceAddress oldInvoiceAddress = glDao.findAddressForLastInvoice(manager, invoice);

            refreshedServiceCalculation.setInvoiced(true);
            refreshedServiceCalculation.setVatRateModified(serviceCalculation.isVatRateModified());

您不应该将 Hibernate 创建的类直接序列化到您的客户端，因为您正在发送 Hibernate 工件。这就是导致您的 NoClassDefFound 错误的原因。

您应该使用自己创建的值对象并将 Hibernate 结果转换为这些对象。这将使您摆脱指向 Hibernate 特定类的隐藏链接。

您有一个或多个使用 fetch = FetchType.LAZY 定义的实体关系。作为此关系一部分的关联实体将替换为 AbstractComponentType。

由于 org.hibernate.type.AbstractComponentType 类不包含在 JBoss 客户端 jar 中，JVM 会抛出 ClassNotFoundException。

因此，要解决这个问题，您可以将 FetchType 更改为 EAGER，或者您可以确保在向客户端发送响应之前在会话 bean 中初始化关系。

（您也可以在您的类路径中添加一个包含 AbstractComponentType 类的 jar，只要客户端不会尝试访问被此 AbstractComponentType 替换的实体——我不推荐最后一个替代方案。）

根本问题是 ServerResponse 正在填充引用 org/hibernate/type/AbstractComponentType 的数据，并且 hibernate 类不在 swing 客户端的类路径上。您可以将休眠类添加到客户端类路径，但更有可能您发送回的对象比您想象的更重且包含更多引用。

没有足够的关于该类的信息以及一般如何制作发票来了解更多信息，但异常表明这是核心问题。

堆栈跟踪表明当您在保存时尝试将 Invoice 实例发送到服务器时，客户端中的类“org.hibernate.type.AbstractComponentType”不可用。

某个地方的类定义有错误，或者您必须将休眠 JAR 添加到客户端的类路径中。
