Lukasz Lenart commented on WW-4874: ----------------------------------- I would wait till 2.6 - this change can impact users. I have created 2.5.15 just to cover the latest discovered issues but it should be a small release (in case of number of fixed issues). We can work on both releases the same time - we can create a branch off of the latest 2.5.14.1 tag. > Asynchronous action method > -------------------------- > > Key: WW-4874 > URL: https://issues.apache.org/jira/browse/WW-4874 > Project: Struts 2 > Issue Type: New Feature > Components: Core Actions, Dispatch Filter > Reporter: Yasser Zamani > Labels: action, asynchronous > Fix For: 2.5.x > > Original Estimate: 1,344h > Remaining Estimate: 1,344h > > User will be able to return {{java.util.concurrent.Callable<String>}} in > their actions. Struts when sees such result, runs {{resultCode = > result.call();}} in it's own managed thread pool but exits from servlet's > main thread with a null result, i.e. gives back main thread to container and > leaves response open for concurrent processing. When {{resultCode = > result.call();}} returned, Struts calls > {{javax.servlet.AsyncContext.dispatch()}} and {{resumes request processing}} > within a container's thread servlet to generate the appropriate result for > user according to {{resultCode}}. > This adds better support for SLS (Short request processing, Long action > execution, Short response processing) via Servlet 3's Async API. > Support of other cases like SSL (e.g. a download server) or LLL(e.g. a video > converter server) is still open. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
