I'm new in spring roo. I want to create a page with file upload. I used spring roo to create all pages and i try to use it to create a file browser button in file upload page. The problem is spring roo using spring form tag which doesn't have file browser. I solve this problem by using html input type="file" tag instead, but the spring roo showed the error like this "Failed to invoke handler method [public void egat.spring.roo.ptu.io.web.ImportExcelController.p ost(java.lang.Long,org.springframework.ui.ModelMap ,javax.servlet.http.HttpServletRequest,javax.servl et.http.HttpServletResponse)]; nested exception is java.lang.IllegalStateException: Could not find @PathVariable [id] in @RequestMapping "

How can i solve this problem?
