Re: download file

[Paweł Wielgus]

Hi,
read this:
http://struts.apache.org/2.0.6/docs/stream-result.html

and this (note that it's to much as for a simple download but that's
what i've got):

package com.ppp.oko.struts.action.motion.file;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;
import java.text.ParseException;
import java.util.Map;

import javax.servlet.ServletContext;

import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.interceptor.SessionAware;
import org.apache.struts2.util.ServletContextAware;

import com.opensymphony.xwork2.ActionSupport;
import com.pi.eplatform.suirz.common.DateRepresentation;
import com.ppp.oko.logic.MotionFile;
import com.ppp.oko.logic.user.Obserwator;
import com.ppp.oko.logic.user.User;
import com.ppp.oko.persistence.prevayler.Motion;

@Result(name="success", type="stream", params={"contentType", "image/jpeg"})
public class ShowAction extends ActionSupport implements
ServletContextAware, SessionAware {

    private static final long serialVersionUID = 1L;
    private String number;
    private String date;
    private long id;
    private ServletContext sc;
    private Map<String, Object> sessionMap;

    public InputStream getInputStream() throws ParseException,
FileNotFoundException {
        Motion motion = ((Obserwator)
sessionMap.get(User.class.toString())).getMotion(new
DateRepresentation(date), number);
        MotionFile motionFile = motion.getMotionFile(id);
        String appPath = sc.getRealPath(".");
        String pathname =
appPath+"/WEB-INF/user/fotki/"+motionFile.getMotionFileName();
                return new FileInputStream(new File(pathname));
    }

    public void setNumber(String number) {
                this.number = number;
        }

    public void setDate(String date) {
                this.date = date;
        }

        public void setId(long id) {
                this.id = id;
        }

        @Override
        public void setServletContext(ServletContext arg0) {
                this.sc = arg0;
        }

        @Override
        public void setSession(Map<String, Object> map) {
                this.sessionMap = map;
        }

}


Hope that helps,
Paweł Wielgus.
