The Spring tag groups are available in the JSP Editor Palette for a Spring project. For a non Spring web project, you can add Spring facet by right clicking on the project > MyEclipse > Project Facets[Capabilities] > Install Spring Facet and the Spring tag groups will be available in the JSP Editor Palette.
You can drag and drop the components from these tag groups into your JSP page. Attached is the screenshot for your reference.
Hope this helps. Let us know if you see any issues.
