[jboss-jira] [JBoss JIRA] (AS7-4935) JSP rendering via AsyncContext.dispatch returns blank page

Rossen Stoyanchev created AS7-4935: -------------------------------------- Summary: JSP rendering via AsyncContext.dispatch returns blank page Key: AS7-4935 URL: https://issues.jboss.org/browse/AS7-4935 Project: Application Server 7 Issue Type: Bug Components: Web Affects Versions: 7.1.1.Final Reporter: Rossen Stoyanchev Assignee: Remy Maucherat The scenario involves: # ServletA forwards to Servlet B # ServletB calls request.startAsync and starts new thread # New thread renders JSP For the JSP rendering if asyncContext.dispatch("") is used I get a blank page in the browser. However if request.getRequestDispatcher("") is used along with forward/include, rendering succeeds. I didn't see any exception in standalong/log/server.log but maybe I didn't enable logging correctly. Here you can find a project to use along with instructions: https://github.com/rstoyanchev/dispatch-test Beyond the bug I would like to confirm it is safe to use request.getRequestDispatcher from an async thread. The spec doesn't say otherwise and it seems to work in AS 7.
