Bootstrapping Jersey With POJO / JSON Mapping

Jersey is the JAX-RS reference implementation by Sun / Oracle. The bootstrapping process is relatively straightforward. It is done by declaring Servlet(s) to handle the Jersey requests.

The basic configuration (without POJO / JSON mapping) can be found here: http://www.mkyong.com/webservices/jax-rs/jersey-hello-world-example/

To add POJO / JSON mapping:

• Ensure the following jar files are on classpath:
• asm
• jackson-core-asl
• jackson-jaxrs
• jackson-mapper-asl
• jackson-xc
• jersey-core
• jersey-json
• jersey-servlet
• jersey-server
• web.xml should look something like this:

<servlet> <servlet-name>WsServlet</servlet-name> <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> <init-param>     <param-name>com.sun.jersey.config.property.packages</param-name>     <param-value>com.xxxxx.ws</param-value> </init-param> <init-param> <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name> <param-value>true</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>WsServlet</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping>
