RMIIO和NoClassDefFoundError

Question

我正在尝试将一个文件从客户机(JSE)上传到服务器应用程序(Java、EJB、Wildfly)。我正在尝试使用此页中的第一个示例，但是当我试图在Wildfly服务器上运行服务器应用程序时-我得到了以下错误：

我不明白为什么找不到这个类(com/healthmarketscience/rmiio/RemoteInputStream)。我使用一个Maven，并将它添加到我的pom.xml中

<dependency>
    <groupId>com.healthmarketscience.rmiio</groupId>
    <artifactId>rmiio</artifactId>
    <version>2.0.5</version>
</dependency>

所以我在我的项目里有了rmiio图书馆。

我该如何解决这个问题？

Answer 1

我解决了这个问题。一步一步地做我所做的：

1. 我在Wildfly_HOME下创建了以下路径: rmiio库的WILDFLY_HOME\modules\system\layers\base\com\healthmarketscience\main。
2. 我在rmiio-2.0.5.jar目录中添加了一个module.xml文件和一个main文件。下面是module.xml文件：
3. 我将一个jboss-deployment-structure.xml文件添加到项目中的META-INF目录中。下面是jboss-deployment-structure.xml文件：
