Project nestor builds a modular enterprise application server based on OSGI and Declarative Services.

See also:

Development environment is based on Eclipse+BndTools.

Main nestor components are:

  • a generic, configurable object pool
  • a jdbc database connection pool, configurable with OSGI Config Admin and using an OSGi DataSourceFactory.
  • a transaction manager implementation
  • a transactional jdbc database connection pool.
  • a whiteboard for JAX-RS applications using Jersey and Jackson
  • a whiteboard for SOAP web services using the JAX-WS implementation included in Java SE.

This repo contains the following Bundles (BndTools projects)

  • cnf: BndTools bundle repository
  • com.amplifino.counters: thread safe counters
  • com.amplifino.nestor.associations: lazy references to map rdbms foreign keys.
  • com.amplifino.nestor.bndrun.template: template for bndrun files containing essential bundles for interactive testing.
  • sample rest whiteboard application showing graphical view of bundle wiring
  • java interface to external GraphViz dot program
  • com.amplifino.nestor.jaxrs: OSGI RFC217 rest whiteboard using Jersey
  • com.amplifino.nestor.jdbc.api: fluent api on top of JDBC
