Singleton with jetty webapps

Question

I want to inject object that has 12mb into my jetty webapp. I deploy my app as WAR file so I cannot add guice injector as it is shown in other question.

How to do it? I quess I need to use applicationContext.xml

Answer 1

Use the ServletContext.setAttribute(String,Object) to store your object.

Then use ServletContext.getAttribute(String) to access that singleton from your Servlets and Filters.

Make sure your object is safe to use from multiple threads!
