Temporary file got override

docvominh — Fri, 22 Nov 2019 06:23:15 -0500

Hi Fold,

I got an issue with ch.ivyteam.ivy.scripting.objects.File.

When our Ivy application receive a file via SOAP with the same name all the time Ex: Information.html

We create a temporary file

ch.ivyteam.ivy.scripting.objects.File file = new ch.ivyteam.ivy.scripting.objects.File(path,true)

The problem happens is when 2 requests come at the same time, the second temporary file overrode the first one.

Is there any way to avoid it without change file name? or add subfolder (caseId) like IDocumentService in temporary file?

How to persist fields in ivy repo but not index in elastic?

adamf — Tue, 24 Sep 2019 02:58:44 -0400

For some projects it is interesting to store all data including files to the database so we can run such instances in docker and share the database. This way it would be possible to store the data in the business repo, even as we seen in https://answers.axonivy.com/questions/1779/how-can-i-persist-a-file-as-blob it is not always efficient. But we would not need to index the base64 conent of the file in elastic. Is it possible?

How to upload a File to a REST api

SupportIvyTeam — Thu, 18 Apr 2019 04:05:19 -0400

I am building a document management service with a RESTful API.

@Path("fileUpload")
public class FileUploadService
{
  @PUT
  @Produces(MediaType.APPLICATION_JSON)
  @Consumes(MediaType.MULTIPART_FORM_DATA)
  public Response uploadFile(@FormDataParam("file") InputStream fileStream,
          @FormDataParam("file") FormDataContentDisposition fileDetail) throws IOException
  {
   .... 
  }
}

It seems to work as expected if I use a third party client such as Postman. However, when using the REST activity of ivy I am unable to call this service. I always get errors stating the the header X-Requested-By is missing. Whats the issue? How can I send files using a REST Client Call activity?

How to access file picked up by FilePickupStartEventBean?

Adrian — Fri, 23 Nov 2018 09:16:12 -0500

Hello. I'm trying to create a simple process that takes the file at a specified path and logs its name(Java Program Start -> Script -> End).The problem is that I'm not sure how I can access the file in the script element.

How to quick search for some text in a mod file?

Emmanuel Comba — Thu, 17 May 2018 10:47:34 -0400

Hello IvyTeam,

We need often to search for some code snippet in some big Ivy Process files (.mod). We can do it in the text editor but it is not very handy to change anything there. The best would be to search with CTRL+F for some text. Then the designer should highlight the Steps where this text has been found. This would be a great help for our productivity.

Do you plan to do such an improvement?

Thanks in advance Emmanuel

Temporary file is not stored in a session subfolder

Gerald — Tue, 21 Nov 2017 08:06:27 -0500

Hi,

we are using the ch.ivyteam.ivy.scripting.objects.File object to create a temporary file, which we want to use as a source for a stream. This seems to work fine and we have no troubles in our development environment.

In our productive environment, however, we expierence sometimes a "file not found" exception. As far as I know, the temporary files should be stored in a temp folder like /files/sessions/{sessionID}/ .

In our environment, these files are not in a session subfolder but can be found directly in the folder /session/tempfileXYZ. We therefore assume that whenever we close a session, the whole tempfolder is deleted, which will result in our "file not found" exception for other users.

Is there any way to enable that files will be stored in session folders again?

Thx,

Gerald

Error when getting a File and putting in process Case

jirazazabal — Fri, 16 Jun 2017 11:48:33 -0400

Hi all,

I'm writing a process that must start when a PDF file comes to a folder, and then, use this file (PDF ) in a Dialog to show it to the user -I guess that I can reference in a a-href HTML tag the file to open it by clicking on the link, but I'm not sure if that it's the best way to do it-. I have implemented a ch.ivyteam.ivy.process.eventstart.beans.FilePickupStartEventBean start, and this is working fine. Then, in a script step, I'm trying to put the file in context in order to use it later in forms the way I've explained. So I've got a subprocess like:

With this code inside script step:

import ch.ivyteam.ivy.workflow.document.IDocumentService;

File file = new File(in.pdfPath,true);
ivy.case.documents().add(file.getName());

But now, I'm getting this error:

Use a picked up PDF in a process

jirazazabal — Thu, 01 Jun 2017 08:00:44 -0400

I have a process that starts when a PDF file comes to a folder. I have configured a program start like that:

And process data class like this:

But when the process starts when a file arrives to this folder, i have a NULL value in pdfPath attribute. I don't know why this happens, and I need to use this PDF file in HTML Dialogs.

Any idea?

Thanks in advance

How to read file from a subfolder in files/application?

hayit — Fri, 24 Mar 2017 13:48:34 -0400

Hello,

we created a subfolder in files/application and uploaded a file in this subfolder. Now I would like to read this file to send it as an Email-attachment.

File f = new File("subfolder\\testfile.pdf",false);
java.io.File Anhang =new java.io.File(f.getName());
in.anhang=Anhang;

But ivy doesn't find the File. When we upload the file directly in files/application it works.

Thank you.

How to programmatically download a file from Ivy-Server "files/application"-folder into a folder on the client with JSF?

Helmut Burgemeister — Sun, 13 Sep 2015 00:42:00 -0400

Hello! How can I download a file from the Ivy-Server's "files/application"-folder to a folder on the client with JSF per program-code? We are using only JSF in this project. No RIA. Is it possibly to download a file to the client without user-interaction in JSF, at all? Kind Regards, Helmut

Temporary (Ivy) file created by System session will not be deleted

Genzer Hawker — Fri, 16 Jan 2015 09:24:48 -0500

In the documentation of Ivy File (emphasis mine)

A File object can be used to read/write temporary or persistent data. IvyScript Files are created in a confined area that belongs to the running application. Temporary files are created in a session-specific file area and are automatically deleted if a session ends. Temporary Files can be made persistent.

If a temporary File is created, it will be located at {app}/files/sessions/{sessionId}/. The files then will be deleted if the session is invalidated.

Unfortunately, this isn't true for temporary files created by SYSTEM user. The SYSTEM user's session is always have the id of 0, hence all files created in SYSTEM user's session will be located at {app}/files/sessions/0/.

It seems that Ivy Server will never invalidate SYSTEM user's session, thus all files located in the directory will by left there undeleted (same as persistent file).

I don't know whether this is a known fact as a consequence of the implementation that SYSTEM user will never be invalidated or it should be considered (somehow) as a bug?

Thanks for considering my question.

Regards

File management in 5.1.2 jSF

dbalasse — Thu, 15 Jan 2015 17:15:29 -0500

Hello,

i am actually migration a 4.3 RIA application (which i didn't wrote) to a 5.1.2 JSF application.

In the old application we were using the workflowUI and something called DocumentWrapper to take care of the Files linked to a case. Does something similar exist in 5.1.2 JSF ? I've found in the addOns the whole ch.ivyteam.ivy.addons.filemanager package. It is used for RIA but could we reuse something ? Or do we have to develop the whole thing ?

Is storing files in a CMS an option ?

How to switch between java.io.File and ivy.scripting.objects.File?

Björn — Thu, 12 Dec 2013 16:56:28 -0500

From the Xpert.ivy help I succeeded in converting a ivy File Object to an Java File Object by using...

java.io.File tempFile = in.someIvyFileObjectInstance.getJavaFile();

But what about the inverse way: Java File -> Ivy File? I didn't found a solution for this.
