Tomcat Project工程中创建action遇到的问题,请教了

[FreedomLeo]

我是新手,用的开发环境是:
eclipse3.3+MyEclipse6.0GA+Tomcat
我在eclipse中新建了一个tomcat project
然后由于找不到struts.jar包,我就把struts1.3.8中lib目录下的所有.jar文件都导入我的工程中
然后想建立一个action,结果出现如下错误:
No available Struts 1.3 projects found in workspace. All MyEclipse Struts 1.3 wizards
require at least 1 properly configured Struts 1.3 project in your workspace.
If your workspace current contains Struts 1.3 projects please ensure that they are opened and
that their web.xml is valid.

Please correct this situation and try again.

请教高手,这是什么原因啊?
