  • Error when using int-sftp:inbound-channel-adapter. Using the 2.0.3 RELEASE version

    I get the following error when the int-sftp:inbound-channel-adapter starts.
    I checked the host/user/password/port values are all correct.
    The local and remote directories have proper file permissions etc. Any thing that I am doing wrong here? Request for suggestions.

      Also, you might want to upgrade to 2.0.4 since there were some changes and bug fixes that might be related to your issue

        Here is my configuration.

        <int-sftp:inbound-channel-adapter id="sftpInbondAdapter"
        auto-startup="false"
        channel="ftp_Channel_1" session-factory="sftpSessionFactory"
        local-directory="${sftp.localDir}" remote-directory="${sftp.remoteDir}"
        auto-create-local-directory="true" delete-remote-files="false"
        filter="customFilter">
        <intoller task-executor="custom-pool" fixed-rate="1000" />
        </int-sftp:inbound-channel-adapter>
        <task:executor id="custom-pool" pool-size="5-20" queue-capacity="100"
        keep-alive="120" />

          Hi Oleg,

          I get the same error even after upgrading the version to 2.0.4 latest GA build.

            First of all, thanks for your original question. The issue you encountered has been fixed several days ago. The fix will be part of the upcoming 2.0.5 release (Scheduled for June 27, 2011). Please see the following Jira for reference:

            https://jira.springsource.org/browse/INT-1921

            Thus, if you upgrade to the latest Snapshot release, your issue should go away.

            Furthermore, there are several other easy workarounds available for the existing 2.0.4 release to solve your issue. In my opinion the best solution would be to explicitly specify the "remote-file-separator" attribute on the "int-sftp:inbound-channel-adapter" element, such as:

            remote-file-separator="/"

            Alternatively, as long as you ensure that the "remote-directory" has a trailing path separator you should be fine as well (e.g. remote-directory="/poll/")

            Please let us know if this fixes your issue.

              Thanks for your quick response. The work around solved my problem.
