在netbeans中，如果运行的时候，出现如下错误

compile-jsps:

D:\我的资料库\Documents\NetBeansProjects\WebApplication1\nbproject\build-impl.xml:1022: 部署错误: 尚未授予访问 Tomcat 服务器的权限。请在服务器管理器的 Tomcat 定制器中设置 "manager-script" 角色的正确用户名和口令。

有关详细信息, 请查看服务器日志。

构建失败 (总时间: 0 秒)

1、打开“工具”－“服务器”，在左边的服务器列表中选中Tomcat，看右边的Catalina 基目录，打开这个目录

找到文件

C:\Program Files\Apache Software Foundation\Tomcat 7.0\conf\tomcat-users.xml

重新配置如下

<tomcat-users>

<!--

  NOTE:  By default, no user is included in the "manager-gui" role required

  to operate the "/manager/html" web application.  If you wish to use this app,

  you must define such a user - the username and password are arbitrary.

-->

<!--

  NOTE:  The sample user and role entries below are wrapped in a comment

  and thus are ignored when reading this file. Do not forget to remove

  <!.. ..> that surrounds them.

-->

<!--

  <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-script"/>

<user username="admin" password="112233" roles="manager-script"/>

</tomcat-users>

重启服务器就好了。
