Question

我跟随tutorial学习EJB和远程接口。与教程不同，我使用的是IntelliJ，WildFly和Gradle。我在IntelliJ中将EE项目放在一起时遇到了一些麻烦，但在阅读了他们的文档，略读教程等之后。

这里是aPicturesWorthAThousandWords风格的细节：

（抱歉，因为低代表我无法添加图片！）

LibrarySessionRemote：

package com.test.eetestapp;

import javax.ejb.CreateException;
import javax.ejb.Remote;
import java.util.List;

@Remote
public interface LibrarySessionRemote {
    void create() throws CreateException;

    void addBook(String bookName);

    List getBooks();
}

LibrarySessionRemoteBean：

package com.test.eetestapp;

import javax.ejb.CreateException;
import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.ejb.TransactionManagement;
import java.util.ArrayList;
import java.util.List;

@Stateless(name = "LibrarySessionEJB")
@Remote(LibrarySessionRemote.class)
@TransactionManagement
public class LibrarySessionRemoteBean implements LibrarySessionRemote {
    List<String> bookShelf;

    public LibrarySessionRemoteBean() {
        this.bookShelf = new ArrayList<>();
    }

    @Override
    public void create() throws CreateException {

    }

    @Override
    public void addBook(String bookName) {
        bookShelf.add(bookName);
    }

    @Override
    public List getBooks() {
        return bookShelf;
    }
}

EJB-jar.xml中：

<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
          http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd"
         version="3.1">
    <enterprise-beans>
        <session>
            <ejb-name>LibrarySessionEJB</ejb-name>
            <business-remote>com.test.eetestapp.LibrarySessionRemote</business-remote>
            <ejb-class>com.test.eetestapp.LibrarySessionRemoteBean</ejb-class>
            <session-type>Stateless</session-type>
            <transaction-type>Container</transaction-type>
        </session>
    </enterprise-beans>
</ejb-jar>

我相信WildFly设置是正确的。我使用的域具有两个主机控制器，每个控制器运行一个服务器（在同一服务器组内）。我通过部署一个简单的.war并查看结果来验证这是有效的。

对WildFly的EJB部署导致ClassNotFound
