How to upload fies to Knowledge center via Content Service

@shivamg

I wont be able to attach screenshots but I will surely help you with code.
Below is the code snippet of how to use create method.

private Long createDocument(String documentName, Long saveInFolder, double size, ContentService contentService) {
\ tDocument document = null;
\ tLong generatedDocument = null;
\ tint sizeInt = (int) Math.ceil(size);
\ ttry {
\ tdocument = new Document(saveInFolder, documentName, "zip");
\ tdocument.setState(ContentConstants.STATE_ACTIVE_PUBLISHED);
\ tdocument.setSize(sizeInt);
\ tdocument.setFileSystemId(ContentConstants.ALLOCATE_FSID);
\ tgeneratedDocument = contentService.create(document, ContentConstants.UNIQUE_NONE);
\ t} catch (Exception e) {
\ te.printStackTrace();
\ t}

\ treturn generatedDocument;

\t}
First create an InputStream of the original file which you want to upload.
Then use the above logic to create a document and you get the document id.
Use the document id to get the InternalFilename i.e the file path and create an OutputStream if the document created.
Then read from the InputStream and write into the OutputStream.
The document is uploaded into the KC and you have the document id too.

Now that I am aware of upload method in the Appian API i would suggest you to go for upload method because it save a lot of coding and it might be more efficient too.

thanks a lot for this
and one question is when you get the document id
and you call getInternalFileUpload() but this fucntion dont have any parameter so how can you find the path of the location in KC

To find the path use document.getInternalFilename(), where document is a object.

@vinodb thanks
suppose i created a dynamic project to upload a file . how to make it a appian plugin

Can you plz elaborate your scenario?

@vinodb i am jst curious and trying to create the upload button so that i can upload a file in KC
I need a plugin for that

For this, You can use Appian SAIL component "a!fileUploadField()". What is the need to create a plugin?

yes i can but i am practicing to create the same thing to learn plugin creation

@sidhantb when i am creating a instance of document it requires three arguments parentFolderId,name, extension
how do i get parent folder id

@shivamg - You need to take parent folder id as input parameter.
