java - Tomcat 教程 : Why Did This Install Fail?

Question

我正在学习 Tomcat 教程 here特别是 the section of installing the hello world war file to the server container

在安装 ant 时我得到这个错误:

BUILD FAILED
java.io.IOException: Server returned HTTP response code: 401 for URL: http://localhost:8080/manager/text/deploy?path=%2Ftomcat-tutorial&war=file%3A%2F%2F%2Fhome%2Fdavid%2FIdeaProjects%2Ftomcat-tutorial%2Fbuild

这同时使用了 example web.xml和 example build.xml在 Tomcat 站点上提供。为什么会失败，我该如何解决？

Answer 1

HTTP 401 未经授权。您没有配置/使用正确的凭据。

所以失败的不是构建，而是尝试部署应用程序的构建后步骤。

也许你没有关注this instruction for ant file :

• Create a "build.properties" file in your application's top-level source directory (or your user login home directory) that defines appropriate values for the "manager.password", "manager.url", and "manager.username" properties described above.

编辑:This可能有帮助:

You can find the role names in the web.xml file of the Manager web application. The available roles are:

manager-gui — Access to the HTML interface.
manager-status — Access to the "Server Status" page only.
manager-script — Access to the tools-friendly plain text interface that is described in this document, and to the "Server Status" page.
manager-jmx — Access to JMX proxy interface and to the "Server Status" page.
