I want to know how to retrieve the uploaded file by execution listener
Below is my code for execution listener
I want to know how to get that file from 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
