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 can i save bytearrays via the entityclass in a database?

markusinho — Thu, 11 Oct 2018 11:00:01 -0400

Hello,

I am trying to set up an entityclass with a postgres server. I need this database to store some images i upload with the primefaces < p:fileUpload/> tag. With this tag the images are uploaded as a UploadedFile, now I can access the contents via getContents() and I will get the image as a Bytearray (byte[] in Java) .

Now I need to know how can i save this Byte Array via the entityclasses in my postgres database. Postgres allows the datatype bytea for a column for this datatype, but if I add Bytearray as a type for the column in the entityclass AxonIvy throws this error: The field type 'Binary' does not support persistence.

So my question is:
Is there any possibility i can save bytearray or blobs on my postgres server via the entity class?
What are all the classes which support persistence?

Thanks

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 post a file to a start ivp "Requests Start"

NhutNguyen — Mon, 16 Nov 2015 05:07:28 -0500

Hello, I have an example JSP page:


<html>
<head>
<title>File Upload Form</title>
</head>
<body>
This form allows you to upload a file to the server.<br>
<form action="http://localhost:8081/ivy/pro/designer/HREventManager_ivy/150FEF18A5DB6168/start3.ivp" method="post" enctype="multipart/form-data"><br>
Type (or select) Filename: <input type="file" name="uploadFile">
<input type="submit" value="Upload File">
</form>
</body>
</html>

In the start3.ivp page, I have the java code to check the file stream:

import java.io.StringWriter;
import org.apache.commons.io.IOUtils;
import javax.servlet.http.Part;
import ch.ivyteam.ivy.htmldialog.request.impl.HttpProcessRequest;
import javax.servlet.http.HttpServletRequest;
import java.util.Iterator;
Iterator parameters = ivy.request.getParameterNames();
while(parameters.hasNext()){
    String name = parameters.next() as String;
    ivy.log.error(name);
    ivy.log.error(ivy.request.getParameter(name).getClass());
    ivy.log.error(ivy.request.getParameter(name));
}     

HttpProcessRequest r = ivy.request as HttpProcessRequest;
ivy.log.info("r="+r);
HttpServletRequest o =r.getHttpServletRequest();
ivy.log.info("o="+o);
ivy.log.info("content length="+o.getContentLength());
ivy.log.info("part="+o.getParts());
ivy.log.info(o.getMethod());

When run the form,I see nothing in the log about o.getParts. Here is the full output:


uploadFile
class java.lang.String
5z.doc
r=HTTP POST Start Processes/BadgeRequestProcess.mod/start3.ivp(553.553.0.0)
o=org.apache.catalina.connector.RequestFacade@4c384c5a
part=[]

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 ?

Dynamic amount of fileuploads: file not uploading

ahatius — Tue, 21 Jan 2014 20:34:00 -0500

I'd like to give the user the ability to choose the amount of attachments he'd like to provide. To do this I created a datatable with buttons to add and remove attachment-lines:

<p:dataTable id="attachments" var="attachment" value="#{data.attachments}">
    <p:column headerText="#{ivy.cms.co('/labels/vendor')}"><p:inputText value="#{attachment.vendor}" /></p:column>
    <p:column headerText="#{ivy.cms.co('/labels/description')}"><p:inputText value="#{attachment.description}" /></p:column>
    <p:column headerText="#{ivy.cms.co('/labels/amount')}"><p:inputText value="#{attachment.amount}" /></p:column>
    <p:column headerText="#{ivy.cms.co('/labels/attachment')}"><p:fileUpload value="#{attachment.file}" mode="simple" /></p:column>
    <p:column headerText=""><p:commandButton value="delete-row" update="attachments" action="#{logic.deleteAttachment(attachment)}" /><p:commandButton value="add-row"  update="attachments" action="#{logic.addAttachment()}" /> </p:column>
</p:dataTable>

The only problem is, that it seems to not upload the specified file. The submitted form is beeing processed by this script, the output of in.test beeing false:

for(Integer i = 0; i < in.attachments.size(); i++) {
    in.test = in.attachments.get(i).file.exists().toString();
}

The Simple-Fileupload-Demo works, so I guess it can't be a problem with my installation / computer. I just cleared all of the attachments and uploaded only one. So while this is a foor loop, it just iterates through 1 time. Data is stored in my own Data Class Attachment, containing 4 attributes (Vendor, Description, Amount and File).
