【问题描述】：
我在 Netbeans 中创建了一个 Java Web 项目，并且默认创建了 index.jsp 文件，其中包含“Hello World”。我试图运行它，但得到以下错误 -
Deployment error: Access to Tomcat server has not been authorized. Set the correct username and password with the "manager" role in the Tomcat customizer in the Server Manager.See the server log for details.
在阅读了一些博客之后，我修改了tomcat-users.xml文件，目前它看起来像 -
<tomcat-users>
<!--
<role rolename="tomcat"/>
<role rolename="role1"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="role1" password="tomcat" roles="role1"/>
-->
<role rolename="manager"/>
<role rolename="admin"/>
<role rolename="standard"/>
<user username="admin" password="admin" roles="admin,manager,standard"/>
</tomcat-users>
此外，检查 netbeans 中 Tools->Servers->Connection 下的用户名和密码及其正确性，即 admin/admin。
但仍然遇到同样的部署错误。
它在build-impl.xml 中显示错误-
<nbdeploy clientUrlPart="${client.urlPart}" debugmode="true" forceRedeploy="${forceRedeploy}"/>
进行了清理和构建，但没有运气。

有人可以建议吗？谢谢。
【问题讨论】：
-
修改tomcat-users.xml后是否重启过tomcat？
-
Paulius Matulionis - 是的，我确实重新启动了它。
-
我对 Netbeans 了解不多，但我听说它有时会对您的应用程序产生影响。我的建议是使用 clean and build 构建您的项目，从命令行启动 tomcat 并尝试从 tomcat 的管理器页面 localhost:8080/manager/html 手动部署您的应用程序，如果出现问题，请检查服务器日志。

我想我从上面的日志中得到了一些提示，但不知道如何解决它。
Caused by: java.io.FileNotFoundException: C:\Program Files (x86)\apache-tomcat-6.0.35\work\Catalina\localhost\manager\org\apache\jsp\_401_jsp.java (The system cannot find the path specified)。实际上在CATALINA_HOME\work..下创建了类文件，但是由于我为我的项目选择了除CATALINA_HOME\webapps之外的其他位置，因此没有创建_jsp.class 文件。在我看来，这导致了这个问题。不知道如何解决它。你有什么高手的指点吗？
