You can inject ServletContext and ServletConfig. e.g.:
@Context ServletConfig sConfig;
When EE 6 is ready it will be possible to avail of the full injection
of EE resources as one can when say using Servlet. I am in the process
of implementing support for this.
Jersey also has a mechanism to plug-in custom injections. Some
developers have been using this in the interim of waiting for full EE
6 support, mainly for injecting EJB references. I can provide more
details as required.
Note that one can also use JNDI directly, and one can developer a
Jersey-based injectable provider that utilizes JNDI. For example, see
Gerard's blog entry:

You can use Spring (or Guice with GuiceyFruit).
But, if you want a lighter-weight solution in the interim of Java EE 6
i recommend utilize one of the two JAX-RS and Jersey solutions
previously mentioned.
