org - java.net.SocketException: respuesta mal formada del servidor SOCKS, con apache FTPClient

java ftp connection

Question

Estoy intentando conectarme al servidor FTP utilizando Apache FTPCleint en la aplicación java web start. A continuación está el código que estoy usando.

ftpInstance = new FTPClient();

ftpInstance.setRemoteVerificationEnabled(false);

ftpInstance.connect(<HostName>);
int rpyCode = ftpInstance.getReplyCode();

if(!FTPReply.isPositiveCompletion(rpyCode)){
    throw new Exception("Connection Rejected with reply code " + rpyCode + ". - " + <Hostname>);
}

El problema está en la línea ftpInstance.connect(<HostName>) . Se ha lanzado una excepción. Mire el rastro de la pila

El código anterior está funcionando bien en el proyecto normal pero no en el inicio web java.

Cualquier ayuda es apreciada. Gracias.

Ha configurado la configuración del proxy SOCKS que apunta a algo que no es un proxy SOCKS.
