file upload and download in java servlet example - Access Spring beans from a servlet in JBoss

1 Answers

There is a much more sophisticated way to do that. There is SpringBeanAutowiringSupportinside that allows you building something like this:

public class MyServlet extends HttpServlet {

  private MyService myService;

  public void init(ServletConfig config) {

This will cause Spring to lookup the ApplicationContext tied to that ServletContext (e.g. created via ContextLoaderListener) and inject the Spring beans available in that ApplicationContext.

I want to write a simple servlet in JBoss which will call a method on a Spring bean. The purpose is to allow a user to kick off an internal job by hitting a URL.

What is the easiest way to get hold of a reference to my Spring bean in the servlet?

JBoss web services allow you to inject a WebServiceContext into your service class using an @Resource annotation. Is there anything comparable that works in plain servlets? A web service to solve this particular problem would be using a sledgehammer to crush a nut.
