Udhayan, struts doesn't need any installation, if you want to include struts in a project, then you have to include all the struts libraries in your eclipse project, that's all. If you want to simplify your work of creating struts project, then you can use an eclipse plugin for struts. You didn't tell us which version of struts you are using. For Struts 1.x,
this plugin seems to be good. For Struts 2.x,
this plugin looks good (although I've not used any of these plugins)...
