我在tomcat webserver上部署restlet应用程序时遇到问题。
我能够直接从eclipse运行应用程序，但是当我在tomcat上部署时，我遇到了类似下面的问题。
May 10, 2015 10:04:32 AM org.apache.catalina.loader.WebappClassLoader loadClass

我检查过，simple.jar是部署战争的一部分。
有人可以建议这种非法访问是什么以及我如何解决它。
感谢。

我想你混合了Restlet的独立和嵌入式方法：
您是在Eclipse中使用独立方法还是嵌入式方法（例如使用WTP）进行尝试？
这是一个允许您创建嵌入式项目的Maven文件：

可以使用命令mvn eclipse:eclipse初始化Eclipse项目。
