A bundle project producing JAX-RS RI bundles. The primary artifact is an "all-in-one" OSGi-fied JAX-RS RI bundle (jaxrs-ri.jar). Attached to that are two compressed JAX-RS RI archives. The first archive (jaxrs-ri.zip) consists of binary RI bits and contains the API jar (under "api" directory), RI libraries (under "lib" directory) as well as all external RI dependencies (under "ext" directory). The secondary archive (jaxrs-ri-src.zip) contains buildable JAX-RS RI source bundle and contains the API jar (under "api" directory), RI sources (under "src" directory) as well as all external RI dependencies (under "ext" directory). The second archive also contains "build.xml" ANT script that builds the RI sources. To build the JAX-RS RI simply unzip the archive, cd to the created jaxrs-ri directory and invoke "ant" from the command line.

There is a newer version: 3.1.9

/**
 * Jersey client connector provider contract.
 *
 * Connector provider is invoked by Jersey client runtime to provide a client connector
 * to be used to send client requests over the wire to server-side resources.
 * There can be only one connector provider registered in a single Jersey client instance.
 * 
 * Note that unlike most of the other {@link org.glassfish.jersey.spi.Contract Jersey SPI extension contracts},
 * {@code ConnectorProvider} is not a typical runtime extension and as such cannot be registered
 * using a configuration {@code register(...)} method. Instead, it must be registered using via
 * {@link org.glassfish.jersey.client.JerseyClientBuilder} using it's
 * {@link org.glassfish.jersey.client.ClientConfig#connectorProvider(ConnectorProvider)}
 * initializer method.
