. lang。ClassCastException:[Ljava.lang.Object;不能被投射到[lblnditmmthd]

I need a serious help in this issue. May be its very basic, but, I am not able to figure it out. I have a session EJB with one method which returns an enum array, i.e. BlndItmTmMthd array. When, I call the method in the client side, it gives me a ClassCastException.

在这个问题上我需要认真的帮助。这可能是最基本的，但我不知道。我有一个会话EJB，其中有一个方法返回enum数组，即blnditmmthd数组。当我在客户端调用方法时，它会给我一个ClassCastException。

java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to [LBlndItmTmMthd

While debugging, I have found that the ejb method is correctly returning BlndItmTmMthd array by calling BlndItmTmMthd.values(). I am not able to find out the reason. Any idea will be helpful.

在调试过程中，我发现ejb方法通过调用BlndItmTmMthd.values()来正确地返回BlndItmTmMthd数组。我找不到原因。任何想法都是有用的。

AgreementSession.java is the EJB interface which contains the following method declaration:

添加内容从评论下面的协议会话。java是EJB接口，包含以下方法声明:

BlndItmTmMthd[] getAllBlendedItemTimingMethods();

AgreementSessionEJB.java is the EJB that implements it.

AgreementSessionEJB。java是实现它的EJB。

public BlndItmTmMthd[] getAllBlendedItemTimingMethods() { 
    BlndItmTmMthd[] blendedItemTmingMethods = BlndItmTmMthd.values(); 
    return blendedItemTmingMethods; 
}

Now, at the client side, when I invoke the EJB method with the following code:

现在，在客户端，当我使用以下代码调用EJB方法时:

BlndItmTmMthd[] _timingMethods = 
             getLoanScheduleSetupSession().getAllBlendedItemTimingMethods();

I get that runtime exception.

我得到了运行时异常。

The "[L" in your error tells you the problem - Java is failing to cast an array of Objects (that is, an Object[]) to an array of BlndItmTmMthds (a BlndItmTmMthd[]).

错误中的“L”告诉您问题所在——Java没有将对象数组(即对象[])转换为blnditmmthds数组(blnditmmthd[])。

Is BlndItmTmMthd really a java.lang.Enum?

blnditmmthd真的是java.lang.Enum吗?
