[jboss-jira] [JBoss JIRA] Closed: (JBMESSAGING-1131) Add configuration for Remoting servlet transport

Add configuration for Remoting servlet transport ------------------------------------------------ Key: JBMESSAGING-1131 URL: https://jira.jboss.org/jira/browse/JBMESSAGING-1131 Project: JBoss Messaging Issue Type: Task Reporter: Ron Sigal Assignee: Howard Gao Priority: Blocker Fix For: 1.4.0.SP3.CP08, 1.4.4.GA Attachments: build.xml, code_changes.zip, messaging-servlet-service.xml, remoting-servlet-service.xml, ServletExample.java, web.xml In addition to the "http" transport, Remoting also has the http-based "servlet" transport. The servlet transport is the same as the http transport on the client side (they both use org.jboss.remoting.transport.http.HTTPClientInvokr), but they are different on the server side. In particular, CoyoteInvoker, the http transport server invoker, uses the network layer of tomcat/jbossweb, i.e., a ServerSocket with worker threads. But in the servlet transport, a org.jboss.remoting.transport.servlet.web.ServerInvokerServlet fields invocations and passes them to org.jboss.remoting.transport.servlet.ServletServerInvoker. The advantage, which came up in a forum thread recently (http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4098850#... and http://www.jboss.com/index.html?module=bb&op=viewtopic&t=122218 ), is that only one ServerSocket is used. In principle, it's the appropriate transport to use when the server is running inside JBossAS. In fact, the wiki page "Accessing_EJB3s_over_HTTP_HTTPS" shows how to change the EJB3 transport from socket to servlet. However, there have been a couple of problems. For one, ServletServerInvoker has been a little behind CoyoteInvoker in its development, though I've been rectifying that (JBREM-675 "Problems with Servlet invoker"). For another, the servlet transport needs tomcat/jbossweb for unit testing, and we've never automated that, so it's not as well tested as CoyoteInvoker (JBREM-139 "need automated test for servlet server invoker"). However, I wanted to verify that JBossMessaging can run with the servlet transport, so I created a servlet example, parallel to the http example, along with the supporting configuration files, and it works.
