Question

我遇到以下问题：

我编写了一个EJB，其中的方法可能抛出PersistanceException，这是一个经过检查的异常（实际上，它封装了一个SQLException）。但是当客户端调用其中一个方法并抛出PersistanceException时，客户端会收到UndeclaredThrowableException而不是PersistanceException。

我在网上进行了一些搜索，我知道当客户端调用动态代理时会发生这种情况，而动态代理并非设计用于处理实际抛出的已检查异常。但就我而言，这个动态代理是由容器自动生成的（Tomme 1.6）。这是Tomee的错误，还是我错过了什么？

以下是代码的说明：

PersistanceException类：它是一个经过检查的异常

@ApplicationException( rollback=true)
public class PersistanceException extends Exception
{ 
    ...
}

EJB接口

@Remote
public interface DbManager extends Serializable
{
    public Number runSequence( String datasourceName, String sequenceName) throws PersistanceException;

    ...
}

EJB实现

@Stateless
public class DbManagerBean implements fr.csf.srv.DbManager
{
    public static final long serialVersionUID = 1L;

    public Number runSequence( String datasourceName, String sequenceName) throws PersistanceException
    {
        ...
        if( condition)
        {
            throw new PersistanceException( ...);
        }
    }

    ...
}

客户：

@Stateless
public class ...
{
    @EJB
    private DbManager dbManager;

    public void method()
    {
        ...
        try
        {
            dbManager.runSequence(...);
        }
        catch( PersistanceException e)
        {
            // The expected exception, but we never arrive here
        }
        catch( Throwable e)
        {
            // Unexpected exception. We get here, instead of the PersistanceException catch.
        }
        ...
    }
}

更新（2014年9月1日）：我安装了最后一个Tomee版本（1.7.0），但它没有改变任何东西。问题仍然存在。这是堆栈跟踪。但它并不完全适合上面的例子，因为我必须简化它，而不是打扰我的应用程序的业务方面。

Answer 1

我已经使用其他容器（Glassfish 4.0）测试了我的应用程序，它运行得非常好。所以我现在可以告诉它，它确实是Tomee 1.6.0中的一个错误，不幸的是，这个错误在最新版本1.7.0中没有得到纠正。似乎MagicWand找到了一个补丁，但我无法让它发挥作用。是否有一个jar文件可以下载并放入Tomee lib目录？或者在JVM类路径中？谢谢您的帮助。 JMB。

Answer 2

您使用的是哪个版本的TomEE，因为此错误看起来像是与您的代码无关的容器问题。似乎TomEE 1.6.0有一个bug，我找到了类org.apache.openejb.util.classloader.ClassLoaderAwareHandler here的修复程序。可能与您的情况无关，但我建议您尝试将TomEE升级到至少1.6.0.2如果您不打算破坏兼容性，或者您可以升级到最新和最好的版本1.7.0并查看它是否有效

使用Tomee 1.6调用EJB方法时出现UndeclaredThrowableException

PersistanceException类：它是一个经过检查的异常

EJB接口

EJB实现
