我正在使用 Apache TomCat 服务器在 eclips 中运行 WEB 服务程序。我正在手动运行它。在此期间，它会给我错误，即找不到符号 LoginResource.class。
我有两个文件 LoginResource.java 和 LoginApplication.java。两个文件都被编译但是当我在服务器上运行它们时它给了我这个错误。当我直接在服务器上运行整个项目时，它会运行，但是当我手动运行服务器时会出错。
为了解决这个问题，我将两个文件（.class）放在同一个文件夹中，但仍然是同样的错误。任何人都有解决这个问题。以下是我的两个 .java 文件- LoginApplication---->
package com.login;
import org.restlet.Application;
import org.restlet.Restlet;
import org.restlet.routing.Router;
public class LoginApplication extends Application {
public Restlet createInboundRoot() {
Router router = new Router(getContext());
router.attach("/login", LoginResource.class);
return router;
}
}
