download file

[PEGASUS84]

please
can anyone send me the cplete code to create an action which allows to download a 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.

Right it's  really too much
because i've not many packages that you've used.

is there a more simple code ?

[Paweł Wielgus]

Nope, that's all i've got,
but You can try to remove all that's unimportant.

Best greetings,
Paweł Wielgus.

       InputStream inputStream;


   public void setInputStream(InputStream s){inputStream=s;}
   public InputStream getInputStream(){return inputStream;}

   public String execute(){
   return "sendFile";
   }
}
and in Struts.xml i've this:

<action name="fileDownload" class="action.FileDownload" >
               <result name="sendFile" type="stream">
               ${contentType}
               </result>
       </action>

i wish to download a file

[Nils-Helge Garli]

And where does your input stream come from?

So you'll need a "contentType" action property. If you look at Pawel's
email you'll see where he opens a file and uses it as the input stream:

String pathname = appPath + "/WEB-INF/user/fotki/"
                   + motionFile.getMotionFileName();
return new FileInputStream(new File(pathname));

There's also a complete example in the showcase application.

Hi all,

I've seen this topic beeing discussed several times already, but I didn't find a solution that works for me.

What I already got:
I invoke an action with a sx:a (targets="dialogContainer"). The action opens a document and has two possible return values: "prompt" and "download".
"prompt" means, that there are several information necessary before the document can be downloaded. It is type="tiles".
"download" means, that the document is ready for download. It is type="stream".

On the "prompt" page is a finish button, that has no targets set, so the download starts fine.
If the action returns "download" immediately it shows the stream in the specified "dialogContainer".

What I need is to modify the targets value out of my action.

I tried it from within the action and with an interceptor, but it seems like I can't access the "targets" in the ValueStack.
Another way I tried, was to use afterNotifyTopics and redirect the data to what I want - but that didn't work either. (Problem with the stream result)

Can someone give me a hint, how I can possibly solve it?
I even thought about modifying the freemarker template for the anchor tag - but I couldn't find the right spot, where to do it.

Any help appreciated!

Kind regards
Jan

targets can be set like anything else, with an ognl expression, like

<s:a .... targets="%{targets}" ..

then you need a getTargets() method in your action. Is that what you
need? or you need to modify the targets on the client side, meaning in
javascript?

the target refers to the component whose content will be updated
<img id="loadingImage" src="images/loadingAnimation.gif" style="display:none"/>
<s:div id="parentDiv">
    <s:form action="actionName">
        <sx:a targets="parentDiv" showLoadingText="false" indicator="loadingImage"/>

dialogContainer is too general and not a component per se
best to identify a div tag such as parentDiv

[Jan Froehlich]

Martin & Musachy, thank you for your replies.

@Martin, sorry that I couldn't make it that clear - "dialogContainer" is a div that is embedded in my page.

@Musachy
I did some more research, and I guess I can't solve it in any way.
If my action returns "prompt" (tiles) it works like a charm and updates my "dialogContainer" with the specified tile.
But when it returns "download" (stream) it doesn't matter (afaik) which targets I define, cause an ajax request wont start a file download in any case.

What could solve my problem is something like a javascript, that takes the returned stream from the action and instead of updating the targets-component it should change the mime type to application/octet-stream and writes it (maybe) to a new window.

Hope its now understandable what I need to do! ;)

Thanks again!

Kind regards
Jan

early here in EDT so I'll make the suggestion for the Action class changing the ContentType
FileUploadAction.setContentType("application/octet-stream");

[Jan Froehlich]

Hallo Martin,

if I see that right, you speak german too - so lets make it a little easier - if not - just ignore the rest of the message! ;)

Das Ganze ist ein bisschen komplizierter als das Ändern des Mime Types.

Um das ganze mal ein bisschen detailierter zu umreißen - ist mir im englischen zu kompliziert:

Ich rufe eine Action auf, die sich solange selbst aufruft und ein tiles Ergebnis zurückliefert bis alle notwendigen Eingaben vorgenommen sind.
Im Code sieht der Aufruf etwa so aus:
<s:iterator value="documents" var="document">
        <s:url var="urlOpenDoc" action>
                <s:param name="documentId" value="#document.id" />
        </s:url>
        <sx:a href="${urlOpenDoc}" targets="dialogContainer"><s:property value="#document.name" /></s:a>
</s:iterator>

Solange ich ein Tile als Ergebnis bekomme ist alles schön und gut. Das wird korrekt dargestellt.
Wenn aber alle Eingaben erledigt sind, liefert die Action ein Stream result zurück.
                        <result name="download" type="stream">
                                <param name="contentType">application/octet-stream</param>
                                <param name="inputName">inputStream</param>
                                <param name="contentDisposition">filename="${fileName}"</param>
                                <param name="bufferSize">1024</param>
                        </result>
Das ist schon entsprechend Konfiguriert um eine Datei zum Download anzubieten.
Problem an der Stelle ist dann nur, dass der Aufruf über Ajax erfolgt und als Target immer noch den dialogContainer hat.
Der Stream wird also im dialogContainer angezeigt, aber nicht als Download.

Ich muss also irgendwie aus der Action heraus sagen - hey - das ist kein tile, das ist ein Download - also geh nicht in das Target, sondern geh in das "Fenster" und zeig mir den Download Dialog.

Ist glaube ich immer noch recht chaotisch und unverständlich, aber vielleicht wird jetzt etwas deutlicher, was genau ich für ein Problem hab.

Vielen Dank auf jeden Fall!!

Viele Grüße
Jan

early here in EDT so I'll make the suggestion for the Action class changing the ContentType
FileUploadAction.setContentType("application/octet-stream");

Hi musachy,

oops - I thought I sent the mail just to Martin. :D

However with that mail I just wanted to explained to him, what my problem is - cause I thought he might have misunderstood what I mean.
What I think is, that there is no way to achieve what I want to do.

Guess that's what you are telling me too!

Thanks so far!

Jan
