Re: How to retrieve uploaded files from alfresco database?

If you have an attachment ID (from when you uploaded the attachment), then you can use the taskService 

taskService.getAttachment(attachmentId);

If this returns not null, then you can get the attachment content using:
InputStream attachmentStream = taskService.getAttachmentContent(attachmentId);

Hope this is what you were looking for,

Hi,

Thank you

I may need more help regarding this as I am new to this.

Can you please please provide the full implementation of this.

I am doing something like this

Also how do you get the attachment id provide you know the form id

TaskService taskService  = processEngine.getTaskService();

if(taskService.getAttachment("uploadurl")!=null){

InputStream attachmentStream = taskService.getAttachmentContent(attachmentId);

}

Here uploadurl is the form id for file upload

I think I am not doing it right

Please help
