Errai on Websphere

djordjevs Jul 4, 2012 8:37 PM

Hi,

I am aware that Errai currently does not support Websphere as seen in https://issues.jboss.org/browse/ERRAI-56 and https://community.jboss.org/thread/201292.

Unfortunately I don't have a choice, but to use Websphere. When I deploy and run my app in Websphere 7 I get the exceptions below. Please note the app works perfectly well in Tomcat.

My question is, is the exception result of the CDI issue in Websphere or some other problem.

1. If it is a non CDI related issue could you please provide some additional pointers where to look.

2. If it is the CDI issue (looks like that), could you please give some advice how to convert Errai CDI apps into non-CDI aps to avoid this problem.

On a different note, in both Tomcat and Websphere I am getting the lines related to marshaller class generation at runtime (in green colour).

3. Can those classes be generated during build/compile time instead of at runtime?

Thanks

SDJ

1. Re: Errai on Websphere

djordjevs Jul 6, 2012 1:22 AM (in response to djordjevs)

Hi,

I have tried to get hold of message bus on the server by doing MessageBus bus = ErraiBus.get(); and it did return a non null bus but the client subscription did not happen and I could not push the messages to the client. In this test I did not use @Service and @Inject annotations.
Also this time I did not get [ErraiMarshalling] failed to load static marshallers issue (though could be because the objects had not initialised properly).

So, would MessageBus bus = ErraiBus.get(); be a step in the right direction or is it totally wrong?

Thanks
