play + stax "input contained no data"

[Lee Breisacher]

Hi. I'm trying to deploy a Play app to Stax and I'm getting an exception
in the stax log:

I'm using the latest Play 1.1 and the stax module. I followed the
directions in the stax module documentation
(http://www.playframework.org/modules/stax-1.0/home). I created an empty
Play app with the stax module like this:

> play new appname --with=stax

and built and deployed the war:

> play war ./yourProject -o project --zip
> stax app:deploy -a login/yourProject -u login -p pass project.war

[I changed the names to match my stax account of course]

Any suggestions? I know the play app is "empty", but still seems it
should deploy and run ok.

Thanks,

Lee

Hi,

Sorry, the Stax module was broken for a few days because of a change
in the play script. You can install the 1.0.1 now.

It will work for newly created application, for existing applications
you need to manually create a file in:

<app_dir>/war/WEB-INF

called "stax-application.xml", with the following content:

<?xml version="1.0"?>
<stax-web-app xmlns="http://www.stax.net/xml/webapp/1">
</stax-web-app>

Thanks Erwan. I tried again, from scratch, with 1.0.1 but I get the same
error:

What am I doing wrong?

Hi,

I'm not sure your error is link to play, it may be a programming error
(does you program runs locally?)

Here are the instruction to deploy a Play app on Stax, independently
from the module.
http://wiki.stax.net/w/index.php/Play
(actually all the module does is to automate the stuff on that page).

It cannot really be a programming error -- I have done NO programming
yet. I'm creating an "empty" Play! app using this command:

play new appname --with=stax

When I run that app with play, it runs fine. I get the "default" play
app. However, when I try to run the app using stax (stax run), I get:

running: C:\java\stax-sdk-0.3.6\scripts\run.groovy
ERROR: This is not a valid project dir

So obviously, stax does not think this is a valid stax app. When I
create an "empty" stax app using this command line:

stax create appname

Then I run that app using "stax run", it runs fine.

Bottom line: I'm still unclear about how to create a simple app that is
*both* stax and Play!

Thanks,

Lee

Well you need to export it as a war to create a valid stax archive.

[Roch Delsalle]

This is the script I use to deploy my app without the stax module :

http://gist.github.com/347882#file_deploy.sh

[Lee Breisacher]

Yes I know - and I did export it as a war and deployed it to my stax
account, and got the errors shown below.

But also, it seems to me that the app should run using "stax run" (and
with "play run").
