I want to share an object between my servlets and my webservice (JAX-WS) by storing it as a servlet context attribute. But how can I retrieve the servlet context from a web service?

The servlet context is made available by JAX-WS via the message context, which can be retrieved using the web service context. Inserting the following member will cause JAX-WS to inject a reference to the web service context into your web service:
import javax.annotation.Resource; import javax.servlet.ServletContext; import javax.xml.ws.WebServiceContext; import javax.xml.ws.handler.MessageContext; ... @Resource private WebServiceContext context; Then, you can access the servlet context using:
ServletContext servletContext = (ServletContext) context.getMessageContext().get(MessageContext.SERVLET_CONTEXT); 2 Comments

If you're trying this on a JBoss EAP stack, and you start by creating a Seam project using the New Project Wizard in JBoss Developer Studio, you end up with a commons-annotations.jar file in your WEB-INF/lib (containing, among others, the @Resource annotation). The end result is that your WebServiceContext is not getting filled, and you get a NullPointerException. For us, the solution was simply to remove the commons-annotations.jar, to make sure that the JBoss-included version was used. After that, things went swimmingly. Thanks for the great answer, a real lifesaver!

Is there any other injectable resources other than the web service context ?
If you use Maven add this dependency!!!
<dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>2.4</version> <scope>provided</scope> </dependency> So I solved for avoid conflict error for get ServletContext INFO :
And in class method I use
@WebService(endpointInterface = "choice.HelloWorld") public class HelloWorldImpl implements HelloWorld { @Resource private WebServiceContext context; public String sayHi(String text) { HttpServletRequest request =(HttpServletRequest) context.getMessageContext().get(MessageContext.SERVLET_REQUEST); System.out.println(request.getContextPath());
