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.
