Async support in WebLogic 12.2.1.2.0

[eduard...@datilmedia.com]

Hi,

I'm trying to run this interceptor in WebLogic 12c:

(def test-queue
(interceptor/before
(fn [context]
(let [channel (chan)]
(go
(let [msg (m/publish q/resp-queue "hello")
rec-msg (m/receive q/resp-queue)
response (assoc context :response (resp/ok rec-msg))]
(>! channel response)))
channel))))

I'm getting the following error, has anyone stumbled with the same issue?

INFO io.pedestal.http - {:line 78, :msg "GET /datil-pay-gtw/test"}
ERROR i.p.http.impl.servlet-interceptor - {:line 404, :msg "Servlet code threw an exception", :throwable #error {

Hi,

Thanks for reaching out on the list!
After digging around a bit, I found this stackoverflow question, related to the Java exception you reported, which points the reader to another question.

That exception happens when a servlet attempts to call .startAsync in an initial context/request that isn't async-capable.

I don't have any experience with running a Pedestal service directly on WebLogic (as a WAR).  Perhaps others might be able to chime in with various config settings that worked.

Regards,
Paul

Hi Paul,

Thank for your reply! You are right. I will look into Weblogic specific configurations.
