Java web程序中备份oracle数据库

1.生成备份文件：

public ActionForward createDmp(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response)

public ActionForward findDmp(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response)

public ActionForward deleteDmp(ActionMapping mapping, ActionForm form,

HttpServletRequest request, HttpServletResponse response)

throws Exception String dmpFolder = request.getSession().getServletContext()

.getRealPath("")

+ "\\datas\\dmp\\";

File folder = new File(dmpFolder);

File[] files = folder.listFiles();

String fileName = request.getParameter("dmpName");

for (int i = 0; i < files.length; i++) if (files[i].getName().equals(fileName)) files[i].delete();

request.setAttribute("msg", "删除成功");

break;

}

}

return mapping.findForward("dmpList");

}
