FTP Adapter ORABPEL-11407 Connection closed error.

Question

Hiiii friends
I have configured the connection factory for FTP Adapter (not defined any connection pool). My BPEL process poll the ftp location to get the file.
But no bpel instance is getting generated and domain.log shows the following error. Can you help me in this issue ?

I am not sure what exactly is happening here. I have already established the successful connection with the same FTP server using different FTP clients.

Answer 1

sounds like the ftp server closed the connection. did you try to use other ftp clients from the same machine where the bpel engine is running?
