That’s probably why it took me 5 minutes to port it successfully to OpenWebBeans 1.5.0 ;)

look at the modified file : https://github.com/antoinesd/openwebbeans/blob/1.5.0-with-se/webbeans-impl/src/main/java/org/apache/webbeans/container/OwbCDIProvider.java

It probably needs something nicer to detect if OWB is running in SE or EE but the idea is here

I’m not talking about container. After having added specific part in each implementation, we have the same way to start CDI
I demonstrated that CDI 1.1+ this piece of code could boot CDI in SE if the implementation has what is required

Look at new version of OWB standalone-sample:

https://github.com/antoinesd/openwebbeans/blob/1.5.0-with-se/samples/standalone-sample/src/main/java/org/apache/webbeans/se/sample/Boot.java

No more import of OWB specific classes and yet it runs.

Of course not because Weld 1.2 -> CDI 1.0. I’m talking about CDI 1.1 and 1.2 as it is written in this email subject.

Of course there are limitation especially regarding shutdown. But it is portable way of booting CDI at spec level. Could be interesting to addd this trick to our simple and communicate on it to say that portable CDI support for SE is already here.

We’ll provide a better support in CDI 2.0 but in the meantime this can be useful.
