How can I access the ServletContext from within a JAX-WS web service?

Question

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

Answer 1

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);

Answer 2

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());
