Hi Ramkumar, your question seems unrelated with the topic here.
But here is the answer:
If you don't want to run a separate Task Server you can't use Mina, because it runs separately as a different server.
If you want to use the Task Server capabilities inside a container like tomcat you can instantiate a local implementation. I'm working to provide this out of the box for multiple containers right now.
Buy you can check inside the github repository for an interface called TaskService and its implementation LocalTaskService to see how you can use that embedded in your application.
Cheers
