aijt,
When you add Struts capabilities, right on the first page of the wizard is where you select Struts 1.1 or 1.2. We don’t support removing of capabilities, so please create a new project and re-add Struts 1.2 capabilities to it. You can manually remove struts capabilities from a project by erasing the .mystrutsdata file and removing the Struts nature from the .project file however.
