JBOSS MalformedURLException：未知协议：vfs 使用 RMI答案

【问题标题】：JBOSS MalformedURLException: unknown protocol: vfs using RMIJBOSS MalformedURLException：未知协议：vfs 使用 RMI
【发布时间】：2024-04-21 20:50:01
【问题描述】：

我最近尝试在 JBOSS EAP 6.4 环境中部署我的应用程序，使其在 Tomcat 上完全运行，但在 JBOSS 上，每当我的应用程序尝试从客户端发送文件时，似乎都会出现格式错误的 URL 异常在进行 RMI 调用（特别是 rmiio）时发送给服务器。

我的错误日志包含在下面

通过查看其他示例，我注意到其他格式错误的urlexceptions 包含no protocol 或unknown exception c，但其中大多数似乎是由代码库设置问题引起的，我不相信我有。此外，即使与 RMI 一起使用，我似乎也找不到任何提及 vfs 的内容。任何建议将不胜感激，谢谢！

【解决方案1】：

您在java.rmi.server.codebase 设置中的某处使用vfs:。您只能使用 Java 识别的协议。代码库 URL 几乎总是 HTTP。

【讨论】：

感谢您的回复！因为我使用了System.setProperty("java.rmi.server.codebase", class.getProtectionDomain().getCodeSource() .getLocation().toString());，所以我错过了这一点，并且我假设我的所有路径都只使用文件协议。所以要使用 JBOSS 运行它，我需要设置自己的 HTTP 网络服务器 like so?
