"Unconnected sockets not implemented" when using FTPSClient
-----------------------------------------------------------
Key: NET-327
URL: https://issues.apache.org/jira/browse/NET-327
Project: Commons Net
Issue Type: Bug
Affects Versions: 2.0
Environment: Windows XP SP3, Java 1.6.0_18, Apache Karaf 1.6.0
Reporter: Bengt Rodehav
I'm using Apache Camel as an integration platform. Specifically, at the moment,
I depend on the ftp/ftps/sftp support in the camel-ftp component. Under the
hood Camel uses Commons Net for ftp and ftps support.
Recently, the camel-ftp component was enhanced (on my request) with the
possibility to use a secure data channel. This is accomplished by using the
execProt() (and execPsbz()) method in class FTPSClient.
However, later on (in case Camel needs to reconnect), one of the connect()
methods in the base class to FTPSClient is called. Unfortunately all the
connect methods first create an unconnected socket and then tries to connect
it. The connection factory now associated with the FTPSClient then throws an
exception stating: "Unconnected sockets not implemented".
It seems like the FTPSClient does not support "re-connect" once it has entered
secure communications mode.
