Running Simple Servlet Test gives ClassCastException

[arun-gupta]

Cube workspace is locally checked out and built. Running a simple servlet test using them gives:

Are you using alpha1 or the snapshot?

[arun-gupta]

1.0.0.Final-SNAPSHOT

[lordofthejars]

Ok can you paste here your ocnfiguration file? arquillian.xml

[arun-gupta]

None, configuration all specified in pom.xml at https://github.com/javaee-samples/javaee7-samples/blob/docker/pom.xml

Start at line 728

[lordofthejars]

The problem is here:

 portBindings:
     - exposedPort: 8080/tcp
       port: 8080
    - exposedPort: 9990/tcp
     port: 9990

In snapshot we have changed to make it more easy: see here an example https://github.com/arquillian/arquillian-cube/blob/master/ftest/src/test/resources/arquillian.xml

And concretely:

wildfly:
   buildImage:
   dockerfileLocation: src/test/resources/wildfly
   noCache: true
   remove: true
   exposedPorts: [8080/tcp, 9990/tcp]
   await:
         strategy: polling
   portBindings: [8081->8080/tcp, 9991->9990/tcp]

Note how port binding is using the -> notation. Also if both ports (the exposed one and the internal one is the same) you can do something like:

portBindings: [8089/tcp, 8081->8080/tcp]

In this case port 8089 will be exposed as 8089 and port 8080 will be exposed as 8081

[arun-gupta]

And that was awesome, got my first test working now!

Waiting for 1.0.0.Final-SNAPSHOT to be pushed live now.

[lordofthejars]

👍 A pleasure to help. I have not updated the documentation yet because O expect that users of alpha1 would like to see README of his version.

Of course nay suggestion you had about how to improve configuration are more than welcome.

[arun-gupta]

Release Alpha2 and update the docs ?

I'd love to talk and showcase this. Requiring users to checkout and build the workspace is tricky.

[aslakknutsen]

@lordofthejars We could add links in the Readme to the 1.0.0.Alpha1:README tag etc. Keep master always up to date, but redirect users to the 'old' doc. ?

[lordofthejars]

@aslakknutsen Understood 👍
@arun-gupta about relese Aslak is working on two issues #40 and #43, we can release right now or we can wait.

[aslakknutsen]

We could cut a A2 now, and just move those to A3.

[lordofthejars]

Ok, then this night Iwill update the readme to latest changes and then tomorrow morning we can release. Does it fits to you?

[aslakknutsen]

@arun-gupta Not sure why the SNAPSHOT doesn't show up in the public groups repo, checking with jboss.org. It's there, just not via the normal group; https://repository.jboss.org/nexus/service/local/repositories/snapshots/content/org/arquillian/cube/arquillian-cube-spi/1.0.0.Final-SNAPSHOT/arquillian-cube-spi-1.0.0.Final-20141209.084123-2.pom

[aslakknutsen]

@lordofthejars 👍

[arun-gupta]

@aslakknutsen sounds good, LMK once the coords are available.

[lordofthejars]

BTW @arun-gupta have you used Arquilian Cube with Boot2Docker?

[arun-gupta]

Yes, filed a new issue for that.

When is Alpha2 going live?

[lordofthejars]

ok boot2docker is gonna be complicated because we need a MacOSx machine, and I am not sure that mine is powerful enough, but well I have some idea on how to do it :)

[lordofthejars]

@aslakknutsen is the one that can release a new version I guess.
