how can immutant be configured to serve ips other than localhost (127.0.0.1)

I'm not sure how to configure my immutant installation to serve webpages

when I do:

>> lein immutant run 

>> curl http://127.0.0.1:8080/testing

it works, but

>> curl http://172.20.10.3:8080/testing

which is an alternative ip on my computer does not.

Where can we configure this option?

How do I configure HornetQ for STOMP in Immutant 2

My ultimate purpose is to make WebSocket clients participate in messaging. This seems to be supported and well documented in the sibling project TorqueBox but I can't find any information in the Immutant docs.

How to use config immutant to implement quartz cluster?

I want to start several web-server, and every server has a quartz instance for avoiding the job being interrupted by restarting the server.

I found that immutant can config the single job .But when i run the server i found that the scheme use the not-cluster config.And i do not know how to config it.

immutant failing to add a cache to a web cache container

I have a heimdallr application that is deployed via wildfly. In this application I am using the cache functionality that is provided by the namespace immutant.caching.

The first time I deploy the application everything goes fine without error. If I attempt to redeploy the application I get the following error:

The way I initialize the cache is

(def site-cache (agent
                  (immutant.caching/cache "site-cache" :ttl [ttl :seconds])
                  :error-mode :continue
                  :error-handler (fn [the-agent exception]
                                  (log/error "Exception in Site Agent " exception (string/join "\n" (.getStackTrace *e))))))

With using immutant 2.x my understanding is that the immutant.caching/cache should create the container if it doesn't exist. Is there a way for me to verify the cache container exists, and if not create it before I attempt to add a cache to it?

EDIT: This was being caused by an error with our deployment scripts. A hack had been done to deploy the same .war twice, which caused the application to not shut down properly causing the error.

Can Immutant be configured to use something other than 8080 as well as to use SSL?

I am playing around with immutant and was wondering how to set two things:

• to setup an alternative ssl port
• to use port 80 instead of port 8080

error while using immutant server to access page from browser

Sending an HTTP request while running Immutant

I'm running Immutant. Can/should I use clj-http to send requests, or is there a better way of going about this?

Deploying Immutant to WildFly with several contexts

I have an Undertow web server with Immutant (Clojure), my main- looks like this:

(run
  (-> routes/app
    wrap-something-app-specific
    wrap-params)
  (options
    {:path "/" :port 8080}))

(run
  (-> routes/billing
    wrap-something-billing-specific)
  (options
    {:path "/billing" :port 8081
     :worker-threads 4}))

When running not in a WildFly countainer, it works just fine: localhost:8080/ maps to app routes, and localhost:8081/billing to billing routes. However when I do deploy to WildFly as a ROOT, I can get only one context working, never both. I've tried all combinations of :path / :port params. WildFly logs include this:

13:07:46,295 INFO  [org.projectodd.wunderboss.web.Web] (MSC service thread 1-12) Registered web context /billing
13:07:46,308 INFO  [org.projectodd.wunderboss.web.Web] (MSC service thread 1-12) Registered web context /
................
13:07:46,325 INFO  [org.wildfly.extension.undertow] (MSC service thread 1-12) JBAS017534: Registered web context: /

So how do I make Undertow register both contexts?

Deploying Multiple Immutant WAR files to Wildfly

I don't think this is version specific but I'll specify I'm on Immutant 2.1.0 and Wildfly 9.0.1.Final.

I start with a stock, freshly unzipped wildfly download and run it with $ wildfly-9.0.1.Final/bin/standalone.sh. I run $ lein immutant war in my clojure project with the following in my project.clj:

:immutant {:war {:destination "/srv/wildfly-9.0.1.Final/standalone/deployments/"
                 :context-path "/app1}}

This works fine and I have my app at http://localhost:8080/app1. The problem is when I do this with a second app with :context-path "/app2", wildfly complains:

>Caused by: org.jboss.msc.service.DuplicateServiceException: 
 Service jboss.pojo.\"org.jboss.netty.internal.LoggerConfigurator\".DESCRIBED 
 is already registered"

If I do this process with app2 before app1, app2 gets correctly deployed but app1 gets a complaint. Both can be deployed individually but not at the same time.

I don't know if I'm missing a step at WAR time or missing wildfly configuration or what.

clustered immutant2 instances

Is there any way to run few clustered immutant2 based apps with no deploy to wildfly? I would like to test distributed cache having two REPLs opened but I see no option in immutant docs to have these 2 sessions in 1 cluster.

Looks like for immutant 1.x it was --clustered option for lein.

Preferred way to connect to Immutant Message Queuing service from eg C# application

Title does not include this constraint: the Broker needs to be embedded.

With straight HornetQ I would just use StompConnect to expose the service to the outside world and that would allow .NET clients to connect pretty easily. There's also the possibility of websockets and REST now.

What is the preferred method?

Fail to connect to queue with Immutant messaging

Currently I have an instance of ActiveMQ running, that I am attempting to connect to using immutant. Currently the code for this connection looks like so;

(defn make-ctx
  []
  (log/debug "making context")
  (let [ctx (m/context :host (:host immutant-host) :port (:port immutant-host))]
    (log/debug "context created")
    ctx))

(defn make-listener
  [ctx]
  (let [listener (m/listen topic #(log/debug %) :context ctx)]
    (log/debug "listener created")
    listener))

(defn immutant-test
  []
  (log/debug "testing immutant messaging with ActiveMQ")
  (let [ctx (make-ctx)
        listener (make-listener ctx)]
  (Thread/sleep 15000)
  (.close listener)))

Though my code does not make it passed the make-ctx function. When it attempts to create the context I get the error

The immutant-host is defined as

(def immutant-host {:host "127.0.0.1" :port 61616})

I've been able to connect to my broker with the clamq libray ,and am able to send and receive messages with that. Though because the rest of the application is built with immutant messaging I'd like to stick with that library if possible to keep from having to support several messaging libraries.

Clojure Immutant 2 server Undertow; how to handle http POST?

Putting the following line into my compojure defroutes to use clojure-paypal-ipn calling the two handler functions.

(POST "/paypal/ipn" [] (make-ipn-handler payment/paypal-data payment/paypal-error))

How do I handle a POST request within Immutant?

I'm using Immutant 2.0 with Clojure 1.7-beta1 and building off the Immutant feature demo. Posting directly with cURL give these same results, although I'm trying to use PayPal IPN.

Multiple ring sites on one immutant?

Immutant allows applications to respond to web requests via Ring handlers. Each application can dynamically register any number of handlers, each with a unique context path. This allows you to have multiple Ring webapps that share the same deployment lifecycle.

So it says I can have multiple Ring apps on one immutant but can I/should I have two separate websites running on one immutant: site1.com and site2.com?

This context path is considered the top-level context path - you have the option to bind a handler to a sub-context path that will be nested within the top-level path. The full context is stripped from the url's path before the request is processed, and the context and remaining path info are made available as part of the request map via the :context and :path-info keys, respectively.

It sounds like I can have an app running on site1.com/context1 and site1.com/context2 but not so much two separate domains.

The reason I'm asking is because immutant takes up a lot of my server resources so much so I'm not sure if I can run two immutants. The correct question might be how do I improve performance on my immutant? (I'm not any good with servers/deployment.)
