I have some documents added as a part of process. Now I want to get download link of those documents in my backend task listener bean. How can I achieve that? I searched into apis of RelatedContentService of Activiti but could not get it.
I am using alfresco activiti enterprise 1.4
If you are looking for the api to download the file, you can use
GET api/enterprise/content/{contentId}/raw. For more details check https://docs.alfresco.com/activiti/docs/dev-guide/1.5.0/#_content
{contentId} can be obtained from the RelatedContentService API.

Yes Ciju, I am aware about that but if I have to get it in backend class(without hardcoding any part of the link) how do I get it?
I might not have understood the question correctly. The link itself is not stored anywhere in the database, it would need to be constructed in your task listener. Also, I'm not sure of the use case here, would you mind sharing the use case? Are you generating an email in the task listener with a link to the attachment?
The options that I am aware of are:
1) Via activiti-app UI (Cookie Based Authentication) - /activiti-app/app/rest/content/{contentId}/raw
2) api/enterprise/content/{contentId}/raw (Basic Authentication)
3) The third option is for you to write a Custom REST API on top of the relatedContentService API (https://docs.alfresco.com/activiti/docs/dev-guide/1.5.0/#_custom_rest_endpoints)

Hi Mittal,
I think what you are really asking is, how, inside your task listener, can you "generate" the content links to the documents stored in the process instance. I imagine as part of your delegate service you are saving these URL's for another system, or something like that.
If this is the case, then what you really need is to recover the content ID's for the attached files as this is the only variable in the enterprise API to retrieve raw content.
The content ID for all documents associated with the process instance can be retrieved using the following REST API:
Alfresco Activiti - Enterprise REST Content
e.g. http://localhost:8080/activiti-app/api/enterprise/process-instances/45025/content
If you are looking for the Java equivalent you would use the RelatedContentService.
Check out the following forum post on how to use the RelatedContentService:

Greg
