Jailer is a database subsetting and browsing tool. It is a tool for data exporting, schema browsing, and rendering. It exports consistent, referentially intact row-sets from relational databases. It removes obsolete data without violating integrity. It is DBMS agnostic (by using JDBC), platform independent, and generates DbUnit datasets, hierarchically structured XML, and topologically sorted SQL-DML.
The Apache Open For Business Project is an enterprise automation software project that includes ERP, CRM, E-Business/E-Commerce, SCM, MRP, and CMMS/EAM functions. It is a foundation and starting point for enterprise solutions and can certainly be used out of the box, but is also great for creating specialized applications.
With MetaModel, you use a type-safe SQL-like API for querying any datastore. It is a data access framework providing a common interface for exploration and querying of different types of datastores. It isn't a data mapping framework. Instead, it emphasizes abstraction of metadata and the ability to add data sources at runtime, making MetaModel great for generic data processing applications, but less so for applications modeled around a particular domain.
DataVision is a reporting tool similar to Crystal Reports. Reports can be designed using a drag-and-drop GUI or a text editor. They may be run, viewed, and printed from the application or exported as HTML, XML, PDF, Excel, LaTeX2e, DocBook, or tab- or comma-delimited text files. The output files produced by LaTeX2e and DocBook can in turn be used to produce PDF, text, HTML, PostScript, and more. It can generate reports from JDBC databases or text data files. Report descriptions are stored as XML files.
Tapestry is a rich, component-based object model for developing dynamic, robust, highly interactive Web applications. Applications are constructed in terms of Java objects, methods and properties, instead of URLs and query parameters. It builds and interprets all URLs, dispatching directly to application-specific "listener" methods. It includes complete source code, documentation, tutorials and a complete example J2EE application.
Sculptor is a productivity tool that applies the concepts from Domain-Driven Design and Domain Specific Languages. You express your design intent in a textual specification, from which Sculptor generates high quality Java code and configuration. You can use the concepts from Domain-Driven Design (DDD) in the textual Domain Specific Language (DSL), e.g. Service, Module, Entity, Value Object, Repository. The generated code is based on well-known frameworks such as Spring Framework, Hibernate, and Java EE. Sculptor takes care of the technical details and the tedious repetitive work, and lets you focus on delivering more business value (and have more fun). The DSL and the code generation drives the development and is not a one time shot. The application can be developed incrementally with an efficient round trip loop. Sculptor is useful when developing typical enterprise or Web applications that benefit from a rich and persistent domain model.
