如何解决Eclipse WebApp在Tomcat上通过Maven进行部署会导致错误：“无法在上下文路径中部署应用程序”
| 当我尝试使用命令“ 0”将IBM Developerworks中描述的HelloWorld项目部署到带有Maven 3的Tomcat 7时，出现错误ѭ1。 在列出的应用程序中，我的/ server出现了，但无法启动。 我根据base22的教程修改了我的maven Web项目，并在pom.xml中将Tomcat 2部署的修订“ 2”应用为locitic的descibet。 命令：mvn tomcat:deploy

解决方法
对于Tomcat 7，您需要使用\“ text \” URL进行部署。该URL是脚本部署所使用的URL。
您正在尝试使用\“ gui \” URL进行部署。
设置方法如下：
tomcat-users.xml
<role rolename=\"manager-script\"/>
<user password=\"script\" roles=\"manager-script\" username=\"script\"/>
