jpgreenwald / InjectionServlet.java

Created July 6, 2013 17:20

It seems to be impossible to use CDI within a JAX-RS 2.0 ContainerRequestFilter, but it is possible to first use a WebFilter to obtain the service and then pass it along via attributes.

	package com.swsandbox.resource;

	import com.swsandbox.service.UserService;

	import javax.inject.Inject;
	import javax.servlet.*;
	import javax.servlet.annotation.WebFilter;
	import java.io.IOException;

	@WebFilter(urlPatterns = "/*")

jpgreenwald / GuavaHack.java

Created July 6, 2013 00:41

Google Guava does not work well with Java EE 7 containers like glassfish 4. This is a producer hack to allow for deployment.

	package com.swsandbox.hack;

	import com.google.common.collect.ImmutableSet;
	import com.google.common.util.concurrent.Service;

	import javax.enterprise.context.ApplicationScoped;
	import javax.enterprise.inject.Produces;

	/**
	* This is included to bypass the Java EE 7 issue with Google Guava and CDI:
