    NextBus Public Feed Adapter for Java

    A Java adapter for the NextBus Public XML Feed Service

    Restful Web Service adapter for the NextBus prediction and transit network reporting service. This implementation uses XSD Schema, JAXB and a domain object model to decouple the consuming application from the over-the-wire representation of the data. NextBus is currently providing real-time bus data in several major metro transit agencies including, but not limited to MBTA (Boston), Toronto, Seattle, Brooklyn, Staten Island as well as a number of University towns. In additional to the standalone Adapter, an Enterprise Service Bus pump and demonstration subscription client are available for those interested in Asynchronous integration of the transit feed.

    OFsX

    Oracle File system Extension

    Problem: How can Oracle PL/SQL applications read, write, move or copy arbitrarily large files to or from arbitrary file system locations? Solution: This utility (OFsX) uses PL/SQL, Oracle AQ & Spring Integration to handle reading, writing, copying, moving & deleting of files from Oracle PL/SQL in a general way. Summary: PL/SQL is an excellent language for developing data-intensive, enterprise applications. However, it can be difficult for PL/SQL applications to interact with a file system (Fs). OFsX makes two-way PL/SQL-to-Fs interaction easy.

    OMapper

    OMapper

    Automate your bean mappings seamlessly

    OMapper is a simple library to ease the process of mapping objects or beans from one design layer to another design layer, using annotations. One can specify mappings both in source class (Sink Annotation) and target class(Source Annotation). Supports mapping composed user class objects and array fields. It is NOT an ORM Framework like Hibernate, but it facilitates object to object mapping between different design layers. So, say if hibernate or axis generates DTO's and you want to map them to your own beans , so at that point this framework can be used. Please refer to the wiki for usage guidelines. Key Benefits : => Smaller code foot-print => Faster development time => One time mapping creation => Easy to debug => Reduces the bugs due to missed mappings for large DTOs

    OnAccessFileEncryption

    OnAccessFileEncryption

    EaseFilter OnAcess File Encryption SDK

    Transparent file encryption performs real-time I/O encryption and decryption of the files in any block data with 16 bytes. The encryption uses a 256 bits symmetric key to encrypt or decrypt the data with AES encryption algorithm. Auto file encryption protects data "at rest", meaning the transparent data and files encryption. It provides the ability to comply with policies which can be applied by users, processes and file type. This allows only authorized users and processes to access the encrypted files, unauthorized users and processes can’t access the encrypted files. The Auto FileCrypt Tool was developed with EaseFilter Encryption Filter Driver(EEFD) SDK, a file level encryption filter driver. Run the auto file encryption service with administrator permission, add the managed folders as encryption folder, when the files were added to the managed folder, the files will be encrypted automatically, when files were read, the data will be decrypted in memory automatically.
