War Plugin ==>> Websphere Application Server 8.5 Liberty Profile ==> Application is not running

[Andreas Baumann]

Hello,

I'm using play2-war-plugin version "1.3-beta3".

Generating a war file and deploying on Tomcat 7 works as expected.

After successful deployment on tomcat I tried to deploy the war file on Websphere Application Server 8.5 Liberty Profile.

The deployment works and the application is started.

After that I use the browser to access the Application.

I got no response from the server and in the log file I found:

[[31merror[0m] c.i.w.w.webapp - SRVE0283E: Es wurde eine Ausnahme beim Initialisieren des Kontextes abgefangen: java.lang.IllegalArgumentException: Cannot check isDirectory for a URL with protocol='wsjar'

[[31merror[0m] play - Play server as not been initialized. Due to a previous error ?

What is wrong  ?

What I have to do to fix this problem ?

Best regards

Andreas

I'm using Play 2.3.9  !!!

Hi,

Play2 uses a framework named "reflections" to handle jar loading.

Play 2.3 embeds reflections v0.9.8, which has several issues with
exotic protocoles.

Play 2.4 will embed reflections v0.9.9, with probably a fix for your issue.

But :
- Play 2.4 is not released
- Play2War is not compatible with Play 2.4 RCs yet
- You cannot upgrade manually reflections from 0.9.8 to 0.9.9 because
reflection brakes its public api between the 2 versions, so Play 2.3.x
cannot work with reflections 0.9.9 without modifications
- Play developers don't want to backport reflections upgrade from Play
2.4 to 2.3 because they don't need it (Websphere support is useless
for them).

So, I advice you to forget Tomcat ou WAS deployment and to use Play's
native deployment.

Hi

What "reflections" framework are you talking about?

[Damien Lecan]

This one:
https://github.com/ronmamo/reflections

Play dependency:
2.3: https://github.com/playframework/playframework/blob/2.3.x/framework/project/Dependencies.scala#L63
2.4: https://github.com/playframework/playframework/blob/master/framework/project/Dependencies.scala#L84

This is a dependency of `play-java` module only, not used for Scala projects. I don't know this framework, must learn, but since it's used only for Java projects, what about Scala projects? Can they be deployed to WAS without problems?

Maybe, you should try :)

Hi Damien,

I don't need the deployment for my own internal projects but the big global layer have other middleware strategies.

Our most important customer use the Websphere Application Server 8.5 Liberty Profile as there default deployment Target.

I can not ignore that !!!

It would be nice to establish the playframework as a preferred backend framework for new HTML5 based web  application.

Without Websphere support this will be not possible  !!!

Best regards

Hi,

is it planned to support Websphere Application Server 8.5 Liberty Profile. A response to this question is very important for me.
I'm working with the playframework for years. I'm trying to introduce the playframework as a standard plattform a ver big enterprise (for modern HTML5 based applications).
The support of the Websphere Application Server 8.5 Liberty Profile would be very important to achieve that.

It would be nice to get some feedback.

Best regards

Hi Andreas,

we will release a version of the play-war-plugin compatible with play 2.4.

We cannot give a date, we are all benevolent on this project.

And for WAS 8.5 Liberty Profile, we cannot guarantee that it will work directly.

Our automatic testing uses Tomcat and Jetty: https://github.com/play2war/play2-war-plugin/blob/develop/project-code%2Fintegration-tests%2Fsrc%2Ftest%2Fscala%2Fcom%2Fgithub%2Fplay2war%2Fplugin%2Fit%2FAllTests.scala#L567

Maybe we will need your help if you have some problems with WAS 8.5.

You can also build the plugin yourself and test it on your machine:

Cheers,
