DataNucleus AccessPlatform is a standards-compliant Java persistence product. It is fully compliant with the JDO1, JDO2, JDO2.1, JDO2.2, JDO3, JPA1, JPA2 and JPA2.1 Java standards, and provides a REST API. It complies with the OGC Simple Feature Spec for persistence of geospatial Java types. It allows access to all popular RDBMS available today, together with the MongoDB, LDAP, NeoDatis, JSON, Excel/ODF spreadsheets, XML, BigTable, HBase, and Neo4j databases.
VRaptor3 is a fully-fledged Java Web framework focused on fast development and maintainable code. It intends to make RESTful application development easy. A resource corresponds to a business logic annotated with its path and HTTP method. It runs inside DI Containers (Spring or Pico out of the box) and, therefore, enables full integration with them. Also, using Hibernate is easier: its session is automatically injected by VRaptor, so you just have to use it. VRaptor3 is refactor-friendly, especially in its redirecting configuration. It is also nicely extensible.
The UniversalContainer class is an attempt to provide a class which can act in a manner similar to the untyped variables, arrays, and hash-maps found in popular scripting languages such as Perl and PHP. The result is a class that can hold a wide variety of data and meta-data in a very flexible structure. UniversalContainers can hold integers, doubles, booleans, single characters, strings, and wide character strings. UniversalContainers may also be used as associative maps between strings and other UniversalContainers, or as arrays of UniversalContainers. Routines for database access and REST programming are included, including a JSON serialization engine.
Google Custom Search is a class that performs searches against a Google Custom Search engine, processing the response (search results and/or spelling suggestions) into properties of the object. It uses either cURL or the HTTP stream wrapper, depending on what is available on the server. The user can also specify the character encoding for the search query. Results are also made available in that encoding.
WSF Staff is Web Service Framework for C++, AJAX, and J2ME that is based on Apache Axis2/C. WSF Staff wraps Apache Axis2/C code into C++, and also provides many additional features: a stateful Web services implementation in C++ with instance support, a synchronous and asynchronous client implementation in C++, AJAX, and J2ME, a service-component architecture implementation, support for RESTful Web services and clients, WSDL support with xsd import and export, J2ME client support (based on ksoap), a flexible and extensible code generator to generate any sort of Web service related source code (not only in C++), security support (users, groups, sessions, ACLs, etc.), and a Web application toolkit (webapp) with widget support.
