Ron Sigal commented on JBMESSAGING-1131:
----------------------------------------
I've attached EJB3-JBM-Servlet-Examle.zip to JBPAPP-1274 "Fix JBoss Messaging and
JBoss Remoting so that servlet transport can be used", which is an Eclipse project
with everything needed (as far as I can tell) to run JBM over the Remoting servlet and
sslservlet transports.
By the way, concerning "When reading from the stream (unmarshalling), the JBM
unmarshaller assumes it can always read a int from the inputstream passed in. This int is
the ID JBM use to reconstruct its own packet. If Remoting somehow passes a different
inputstream (maybe some internal packet that is not relevant to JBM) the JBM unmarshaller
has no way to identify, that's why I got EOFException and so I catch it in my
code." The fact that you got an empty InputStream is a Remoting issue, which
I've fixed.
I ran the example using EAP 4.3.0.GA_CP03, with an unmodified JBM. Hopefully, all
that's necessary now is to configure the 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
Fix For: 1.4.0.SP3.CP06, 1.4.3.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.
