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.
Pylets is a fast, lightweight, aspect-oriented Web framework built on mod_python and Apache. It uses Apache logs (and more Apache configuration in the future.) It can use Python objects, packages, and modules, or whatever the programmer wants. Pylets are also template-agnostic. With the debug switches off, and caching turned on, Pylets are less than 2x slower than serving static pages. The package comes with ORMit, a lightweight DB-API 2.0 connector-compatible object relational mapper.
MixedCC (Mixed Compiler Compiler) is a parser-generator framework for multi-layer templates. It also works as a detachable stack machine engine. LL(1) BNF grammars of respective layers are specified in JavaCC-like syntax. The lexer is either JavaCC-generated or user-written. Tokens can represent stack-machine transition commands.
Oness is an ERP, CRM, SRM, and inventory management solution primarily supporting the textile commerce. It is based on J2EE technologies such as Spring, Hibernate, Struts, XDoclet, AspectJ, and Maven with a JSP-based Web interface. It is completely modular and thoroughly documented.
Poor Man's Imaging Wrapper a clean and simple API wrapper over JAI, Java2D, ImageIO, and AWT. It supports a set of imaging operations (read, write, scale/resize, crop, grayscale, add transparency, rotate, add border, flip/mirror, add text, overlay, blur, sharpen, etc.) with simple direct calls to the API. If you want to switch from Java2D to JAI, all you need to do is add JAI jars to the classpath. It supports GIF encoding if PJA tools jars are available in the classpath.
Spinneret is a structured storage engine that can be thought of as an extended tuple storage system. It takes the best aspects of relational, object, and hierarchical databases and throws away the dead weight associated with those technologies. The benefit of Spinneret is that its data model is incredibly flexible, allowing it to expose its underlying data in any number of ways. It operates similar to an object database, but without hard ties to an originating language, and can also behave like a relational database without the burden of complex joins.
Morph is a Java framework that eases the internal interoperability of an application. As information flows through an application, it undergoes multiple transformations. Morph provides a standard way to implement these transformations. In addition to providing a framework for performing transformations, Morph provides implementations of many common transformations. It has been built from the ground up for flexibility and extensibility, and it integrates seamlessly with dependency injection frameworks such as Spring, PicoContainer, and Hivemind.
OpenArm is an implementation of the Open Group's Application Response Measurement (ARM) standard. It provides a complete implementation of the ARM 4.0 Java interfaces, as well as ARM agent functionality that allows you to record your transaction events as log4J logging events, JMS messages, SNMP traps, JMX notifications, or as records in a relational database.
