updatemainproblem.java

是一个J2EE的项目,在eclipse下编译通过,应用struts,hibernate开源框架,界面不是很漂亮.

public class Updatemainproblem extends Action{
	public ActionForward execute(ActionMapping mapping, ActionForm form,
		    HttpServletRequest request, HttpServletResponse response) throws Exception {
		
	    try

	    	m.updatemainproblem(mp);
	    	//保存信息
	    	request.setAttribute("asd", "success");
	    	
	    	
	    }
