Java中的企业应用程序项目

我试图在java中创建一个企业应用程序项目 . 我从http://pl.cs.jhu.edu/oose/resources/j2ee-tutorial/index.php链接中学到了一些基础知识 .

项目结构如下：* EAR（企业应用程序项目）* ApplicationClient（应用程序客户端模块）连接器（连接器模块） EJB（EJB模块）* EJBClient（EJB客户端模块）* JavaUtility（实用程序项目，首先单独创建并添加to testEAR）* DynamicWebApplication（动态Web模块）

我使用JBOSS作为Application Server .

连接器模块作为Java应用程序运行它工作正常 . 连接器模块运行，因为不提供运行服务器选项 .

JBOSS无法安装连接器模块 . 当我尝试在JBOSS上运行EAR时，我得到错误日志 . 贴在最后 .

有趣的是我删除了连接器模块并添加了一个java项目，它运行正常 .

如果我只创建一个Dynamic Web Project并将Web，Java，DB Connection的所有代码放在不同的包中，我是否会放弃Enterprise Application Project可以提供的任何功能？请详细解释这一点，因为据我所知，我们几乎可以将所有内容都放在Dynamic Web Project中 . 你可以参考SourceForge或GitHub中的任何EAR项目，我可以从那里下载并进行逆向工程和逐步学习 . 任何解释ejb，ejb客户端，应用程序客户端项目的教程链接都是受欢迎的 .

运行ear项目时jboss上的错误日志： -
