Hi,

While generating a retention receipt inside of an invoice journal the process stops in a method that validates the FTP

protected void validateFtp()
{
    object                          ftpo = null;
    System.Net.FtpWebRequest        request = null;
    System.Net.NetworkCredential    credential = null;
    System.Net.FtpWebResponse       response;
    ElectronicFTP                   electronicFTP = ElectronicFTP::find();
    ;
    try
    {
        ftpo = System.Net.WebRequest::Create(@"ftp://"   electronicFTP.FtpAddress);
        request = ftpo;
        credential = new System.Net.NetworkCredential(electronicFTP.UserName, electronicFTP.Passwd);
        request.set_Credentials(credential);
        request.set_Method("NLST");
        request.set_Proxy(System.Net.GlobalProxySelection::GetEmptyWebProxy());
        response = request.GetResponse(); //HERE IT STOPS
        request.Abort();
        response.Close();

    }
    catch
    {
        infolog.add(Exception::Error, "No se encuentra disponible el sitio Ftp");
        throw Exception::Error;
    }
}

If there is no response, why it didnt catch the error if it is inside a try catch. It doesn't pop any error message but it doesn't generate any retention receipt, it just doesn't do anything. What could be the problem here?

RE: Process stops while validating ftp

I do not have a ttsbegin / ttscommit where im callling the method validateFtp( ). I have the ttsbegin / ttscommit where I'm doing the query to select the specific document that I'm generating the retention.

Do you have ttsBegin/Commit (at caller, etc)

Are you saying that it doesn't get into the catch block at all?

I would expect it does, you just don't do anything useful there. If you want to see the actual error, do something like this:

rotected void validateFtp() { System.Net.WebRequest request; System.Net.NetworkCredential credential; System.Net.FtpWebResponse response; ElectronicFTP electronicFTP = ElectronicFTP::find(); try { request = System.Net.WebRequest::Create(@"ftp://" electronicFTP.FtpAddress); credential = new System.Net.NetworkCredential(electronicFTP.UserName, electronicFTP.Passwd); request.set_Credentials(credential); request.set_Method("NLST"); request.set_Proxy(System.Net.GlobalProxySelection::GetEmptyWebProxy()); response = request.GetResponse(); response.Close(); } catch (Exception::CLRError) { throw error(AifUtil::getClrErrorMessage()); } }

By the way, your code

infolog.add(Exception::Error, "No se encuentra disponible el sitio Ftp"); throw Exception::Error;

can be simplified to mere

throw error("No se encuentra disponible el sitio Ftp");
