我在我们的应用程序中看到一个奇怪的异常，它结合了EJB3和EJB2。一个简单的购买请求（涉及将一些记录写入数据库）失败。
涉及数据库调用的其他请求工作正常。
堆栈跟踪显示了依次通过多个EJB的代码 - 这些类的代码提取显示在堆栈跟踪下面。

以下是相关代码：
@Stateless //only so we can inject an entityManager
public class AccountDaoImpl implements AccountDAO {
@EJB(beanInterface=MultiTenantEntityManager.class)
private MultiTenantEntityManager multiem;
}
因为我们有多租户，所以我们不能只使用@PersistenceContext注释 - 而是根据this example我们需要一个多租户实体管理器。
AccountBean调用DAO层：
//this is an EJB 2
public class AccountBean implements EntityBean, Account {
AccountDAO mAccountDao;
public void setEntityContext(EntityContext ctx) {
this.ctx = ctx;
if (mAccountDao==null)
mAccountDao = (AccountDAO) ctx.lookup("ercore/AccountDaoImpl/local");
}
public String ejbFindByPrimaryKey(String msisdn) throws FinderException {
mAccountDao.selectAccount(msisdn);
}
}
在AccountBean上配置了事务性，以便将“trans-attribute”设置为Supports。我尝试将此更改为Required，但没有效果。
订阅管理层是EJB2帐户bean的加载位置：
public class SubscriptionManagementImpl implements SubscriptionManagement {
public Account findAccountByPrimaryKey(String msisdn) throws EcommerceException {
Account sAccount = getAccountHome().findByPrimaryKey(msisdn);
}
}
此订阅管理层又由PurchaseBean调用：
public class PurchaseBean implements PurchaseTcApi, SessionBean {
public PurchaseAuthorization purchasePackage(String msisdn) throws RemoteException {
Account account=getSubscriptionManagement(locale).findAccountByPrimaryKey(msisdn);
}
并且委托层正在调用PurchaseBean：
public class PurchaseApiDelegateImpl implements PurchaseApi {
public PurchaseAuthorization purchasePackageMsisdn(String msisdn) throws PurchaseAuthorizationException {
getPurchaseBean().purchasePackage(clientApplicationId,
msisdn, packageId, purchaseAttributes, this.locale);
}
委托层又由servlet层调用。呼！
所以这是一个非常复杂的设置，我不会假装我喜欢它，但它工作正常，直到我开始尝试将事情移到EJB3（现在是AccountDaoImpl）。
我怀疑它可能与交易边界有关。我知道默认设置是Required，这意味着加入一个事务（如果有），否则创建一个新事务。因此，我无法看到事务如何处于非活动状态，因为一旦我们在AccountDaoImpl中输入方法，就应该创建一个事务。
答案 0 :(得分：0)
你可能看起来太遥远了。
是个例外org.hibernate.exception.GenericJDBCException：无法打开连接
您是否可以检查数据库连接的凭据是否正确以及数据库的网址是否也正常？
答案 1 :(得分：0)
我认为实际的根本原因并未暴露在这些堆栈跟踪中。 您可以通过调试器连接您的应用程序，并检查是否未在某处吞下根本原因异常。此根本原因异常可能已中止您的事务并使其处于非活动状态。
