Document creation within plugin

Hi Soujanya,

Could you please elaborate more on this.

Thanks.

Hi Raghavendra,

I am trying to create a custom smart service plugin (using java) where in i have to requirement to read the existing document from Appian knowledge center.How can i achieve this via java code.

Hi Soujanya,

You can use download method of ContentService class to download document from knowledge center.

1. Get the conent Service from the constructor
2. Call the below method to get the Appian document as JAVA File.

Long documentId = 123L;
String filePath = cs.getInternalFilename(cs.getVersion(documentId,ContentConstants.VERSION_CURRENT));  /* you will get something like, C:\appian\_admin\accdocs1\1\10000001.pdf */
File jAppianFile = new File(filePath);

Thanks,

Raghu

How about if I don't have document id, i want to create a document id too (fresh document and fresh id), how is it possible.

Hi Pradeep,

You have to upload document using a!fileUploadField. You can save Document Id in local variable to process it further.

Please have a look at following code.

a!fileUploadField(
      label: "File Upload",
      labelPosition: "ABOVE",
      saveInto: {
        local!docId
      },
      validations: {}
    )

 

 

i mean in plugin creation, i have to create a new document.

Most plugins uploaded to community will include their source code so your best point of reference would be to download and inspect an existing plugin that performs a similar operation.
"PDF Tools" for example shows you how to create new documents using the ContentService and how to retrieve the ID.

Hey,

You can try using the upload method from ContentService

ContentOutputStream upload(Document doc,

                          java.lang.Integer unique)

                   throws InvalidContentException,

                          StorageLimitException,

                          PrivilegeException,

                          InsufficientNameUniquenessException,

                          DuplicateUuidException

Creates a document and provides an output stream to which the document's content should be written. The document is created using the createApproval(Content, Integer) API. The caller must write the document's data to the returned output stream and complete the upload by calling ContentOutputStream.close(). Invoking the stream's close method will calculate the size of the data written to the stream and save it as metadata for the document.

the stream returned can be used to write like any other plain java stream.

for more details, check the ContentService public API definition from developers tab of community.

Hope this helps!
