MalformedURLException:未知协议:使用RMI的vfs

Question

在使应用程序在Tomcat上充分发挥作用之后，我最近一直试图在JBOSS 6.4环境中将我的应用程序部署为war，但在JBOSS上，每当我的应用程序试图在执行RMI调用(特别是rmiio)时将文件从客户机发送到服务器时，就出现了一个错误的异常。

我的错误日志包括在下面

通过查看其他示例，我注意到其他格式错误的例外情况要么由no protocol或unknown exception c组成，但它们中的大多数似乎都是由代码库设置问题引起的，我不认为是这样的。此外，我似乎找不到任何提到vfs甚至与RMI一起使用。任何建议都将不胜感激，谢谢！

您正在java.rmi.server.codebase设置中的某个位置使用java.rmi.server.codebase。您只能使用Java所识别的协议。Codebase几乎总是HTTP。
