uploading content

tog — Thu, 22 May 2008 15:47:19 GMT

Hi,I know there is a web service interface to alfresco but I was wondering if it was possible to upload content using either a command line (curl for example) or by doing a POST request to the server ?CheersTog

I am also interested in this. The WebScriptRequest doesn't provide access to the underlying input stream. I can't see a way of gaining access to it under the covers either. Can anyone suggest a way of getting it, or give a good reason why one shouldn't get it?

Regards
Brian

Hi,
there is a UploadContentServlet: http://wiki.alfresco.com/wiki/URL_Addressability#UploadContentServlet

Or you can roll your own Web Script, which allows you to pass in arbitrary metadata in the same HTTP request:

Hi Mike,
Actually, the doc said it is available in Enterprise edition. I downloaded a trial enterprise version but was not able to find this sample.
Can someone help me on this ?

Best Regards

The sample doesn't ship with the product - just create it yourself from the wiki text.

Thanks,
Mike

Ok I see, thanks for your quick answer.
So what prevent me to use it with the community edition ? - I would feel more comfortable if I can do my mock up with this version and move afterwards to an enterprise edition.

Thanks

You might find one of the JavaScript APIs is missing in 2.1 Community. It'll be in v2.9 though. Try it and see what happens!

Thanks Mike,
I implemented what I found on the wiki.
When I try to run it I am denied the rights to run the script with this error:
I might be missing something here 😉

Look at the root of the exception: org.alfresco.repo.jscript.ScriptNode.createFile(ScriptNode.java:1237). (AlfrescoScript#34) also gives you a hint that the script is running but encountered a problem on line 34.

It's simply that the user you're running the script with doesn't have permissions to create content in Company Home.

Thanks,
Mike

Re: uploading content

tog — Fri, 06 Jun 2008 09:50:38 GMT

Ok Mike,

But there is something I don't understand. Usually when I try to run such a script I am prompted with a pop-up for entering login/password ? In that case not ? Which is the user being used for this action ?

Assuming that I might have been using a previous script with credentials not allowing access to Company Home, how can I terminate the current session from the browser ?

Thanks

Ok I manage to be logged with admin who has the proper right …
But I get a new error:

Exception: org.alfresco.error.AlfrescoRuntimeException - Java class "org.alfresco.repo.jscript.ScriptNode$ScriptContentData" has no public instance field or method named "encoding". (AlfrescoScript#36)

org.alfresco.repo.jscript.RhinoScriptProcessor.executeScriptImpl(RhinoScriptProcessor.java:535)

There is nothing like "encoding" being defined in the webscript.

Any idea ? or should I dig in the source

Thanks

Hi,

I've run into the same problem before, the encoding field is probably not implemented in the version of alfresco that you're using.
Have a look at this post: http://forums.alfresco.com/viewtopic.php?f=36&t=9768

Thanks Roeland
This is working like a charm. Next step is to upload 16GB

Cheers

Re: uploading content

tog — Tue, 10 Jun 2008 07:22:25 GMT

Ok so actually uploading 16GB does not work out of the box. Actually the limit seems to be around 2 GB (1GB and 1.5GB are working fine).
Does someone knows how this is working underneath ? Is the file loaded into memory ? What is the limiting factor ? - the memory of my local machine ?
I should be able to stream my data isn't it hence my other post which is not yet populat

Cheers
Guillaume

Re: uploading content

Ok so most (if not all) browsers have this 2GB limit. I will move to a custom client for uploading files.

Re: uploading content

agatap — Wed, 11 Jun 2008 12:49:14 GMT

Is there any way to upload a file from a form using java - we don't plan on using javascript in our application?
I cant see how to access the input stream from a DeclarativeWebScript.

Best,
Agata

Re: uploading content

tog — Wed, 11 Jun 2008 13:10:30 GMT

Yes this is possible. This is #2 on my TODO list. #1 is a java client to upload files larger than 2GB.
I will post the status later on

Cheers
Guillaume

Re: uploading content

:arrow: I need help !

So in order to circumvent the browser limitation, I have a small client that is able to post a large file to Alfresco …. but large is still smaller because I was not able to write a Java-based webscript using apache commons upload to stream the file.

Here is the pseudo code


public class UploadWebScript extends AbstractWebScript {
    public void execute(WebScriptRequest request, WebScriptResponse response) throws IOException {

       HttpServletRequest httpRequest = ((WebScriptServletRequest)request).getHttpServletRequest();
   
        ServletFileUpload upload = new ServletFileUpload(new DiskFileItemFactory());
        upload.setHeaderEncoding("UTF-8");

        try {
            logger.info("parsing http request");
            List<FileItem> fileItems = upload.parseRequest(httpRequest);
….
    }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

fileItems remains an empty list …???

Similarly, request.getParameter("file") is null !

Can someone told what I am doing wrong here ?

Cheers
Guillaume
