当我刚刚使用jsp既不使用servlet也不使用任何框架时，如何解决绝对uri错误

Question

当我使用此控制器代码时：

public class BuisnessController {

    private Logger logger = Logger.getLogger(BuisnessController.class);

    public void addbuisnessimage(HttpServletRequest request,
        HttpServletResponse response, String bpath) {
        String ret = ""; // For User Registration and File upload code

        String business = "";
        String subbuisn = "";
        String image_file = "";

        try {
            if (request.getContentType().indexOf("multipart/form-data") != -1) {
                List list = new ServletFileUpload(new DiskFileItemFactory())
                    .parseRequest(request);
                java.util.Iterator it = list.iterator();
                while (it.hasNext()) {
                    FileItem fl = (FileItem) it.next();
                    if (fl.isFormField()) {
                        String fname = fl.getFieldName();
                        String fval = fl.getString();
                        if (fname.equalsIgnoreCase("business")) {
                            business = fval;
                        } else if (fname.equalsIgnoreCase("image_file")) {
                            image_file = fval;
                        } else if (fname.equalsIgnoreCase("subbuisn")) {
                            subbuisn = fval;
                        }
                    } else {
                        String filename = fl.getName();
                        File file = new File(bpath,"images");
                        file.mkdirs();
                        String basepath = file.getAbsolutePath();
                        long t = 0;
                        String ext = "error";
                        try {
                            t = new java.util.Date().getTime();
                            int l = filename.lastIndexOf(".");
                            ext = filename.substring(l, filename.length());
                            String fpath = basepath + "/" + t + ext;

                            File f = new File(fpath);
                            fl.write(f);

                        } catch (Exception e) {
                            e.printStackTrace();
                        }
                        BuisnessImageDTO adminRoleDTO2 = new BuisnessImageDTO();
                        adminRoleDTO2.setBusiness(business);
                        adminRoleDTO2.setSubbuisn(subbuisn);
                        adminRoleDTO2.setImage_file(image_file);

                        if (ext.equalsIgnoreCase("error")) {
                            adminRoleDTO2.setImage_file("NA");
                        } else {
                            adminRoleDTO2.setImage_file(+t + ext);
                        }

                        ret = new BuisnessService().addbuisnessimage(adminRoleDTO2);
                    }
                }
            }
            if (ret.equalsIgnoreCase("success")) {
                request.getRequestDispatcher("buisness-add.jsp").forward(request, response);
            } else {

                request.getRequestDispatcher("buisness-add.jsp").forward(request, response);
            }
        } catch (Exception e) {
            e.printStackTrace();
            logger.error("Data Missing", e);
            logger.warn("This is a warning message");
            logger.trace("This message will not be logged since log level is set as DEBUG");

            try {
                request.getRequestDispatcher("buisness-add.jsp").forward(request, response);
            } catch (Exception ex) {
                ex.printStackTrace();
                logger.error("IOEXception occured:", ex);
            }
        }
    }

在我的本地Tomcat上它可以正常工作，但是当我在服务器上部署我的网站时，它会为每个文件夹提供绝对路径错误。即便如此，我也无法获取图像格式数据库。它只显示图像ID，如12356.jsp。我正在使用javax.servlet.jsp.jstl 1.2.1 jar

这是我的xml代码：

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        <exception-type>java.lang.Throwable</exception-type>

    </error-page>

    </context-param>
    <session-config>
        <session-timeout>100</session-timeout>
    </session-config>
    <listener>
        <listener-class>com.haani.atp.group.listener.MyListener</listener-class>
    </listener>
</web-app>

请给我一些建议，因为这是我第一次部署任何网站。
