Hej!

I am relatively new to Seam community and i am developing one portal together with Seam. I am currently stuck in middle, i would like to use Seam together with my custom servlet which extends HttpServlet. I don't have a clue how to connect Seam entities to work with my custom servlet. Now i have entity Itemcategory in Seam and works well with JSF showing data, but when i try to create Itemcategory object in my custom servlet i get this message No application context active.

So i searched for help through net, and found that i need to use some kind of context from Seam. So i am now asking for some useful working example of how to implement Seam functionality into my custom servlet.

I thank you for your help in advance

You need to SeamFilter installed, which relies on the SeamContextFilter to establish Seam contexts around a custom servlet. Then you can get a Seam component as follows:

Component.getInstance(componentName);

Hi Dan, Have you tried it? Do you have any example? Thanks,

You can also wrap your servlet request in a ContextualHttpServletRequest in doGet etc. 


protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
  new ContextualHttpServletRequest(request) {
    public void process() throws Exception {
      // Access seam stuff with Component.getInstance(...)
    }
  }.run();
}
