In a typical J2EE project, we put the application level initial parameter in context-param tag in web.xml, such as database configuration, administrator's email address, etc.
The values within the
String value = getServletContext().getInitParameter("name_of_context_initialization_parameter");
When dealing with Web Service, the same problem comes up.
What if we want to put database configuration information in a configuration file, and let Web Service access it? We want the configuration info is not hard-coded, and therefore can be changed during the deployment stage.
Luckily for us, the servlet context can be access by Web Service too. Servlet Context is 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:
@Resource private WebServiceContext context;
Then, you can access the servlet context using:
ServletContext servletContext = (ServletContext) context.getMessageContext().get(MessageContext.SERVLET_CONTEXT);
What about other ways to put configuration information for Java Web Service?
<pre><code> String foo = "bar"; </code></pre>
