Secure FTP API for Java is a collection of classes that allows you to add secure file transfer capabilities to your Java applications. It has a complete implementation of the File Transfer Protocol as defined RFC 959, and support for secure file transfer using SSL/TLS as defined in RFC 2228. Both explicit and implicit SSL connections are supported. It has an extendable architecture to support legacy/non-standard FTP servers, event notification to notify the connection and transfer events to interested objects, support for active and passive data transfers, support for ASCII and binary data types, and the ability to set the timeouts and buffer size to use for the control and data connections.
Ingres is a feature rich and robust database (RDBMS) that's free to use, modify, and redistribute. Support is available for a reasonable price if you need it. Ingres supports many programming languages, including Python, Ruby, Java, Perl, C/C++, and more. Ingres has a bit of a learning curve, but once mastered is extremely powerful and highly tunable. It is also very stable and reliable. Ingres is one of a fairly small number of databases providing excellent geospatial features including data types and functions compliant with the Open Geospatial Consortium (OGC) Simple Feature Specification (SFS) for SQL.
