David Hubbard commented on SOLDER-322:

Jozef, thanks I've applied your patch ok to the quickstart example and deployed that fine - I did have to digest the diff file a little (what with the a and b folders it seemed to create when run in Eclipse).  Will try it on my project which actually uses Seam Persistence shortly.   

Couple of questions - 1) what version of JBoss AS are you targeting for Weld 2.0.0 ?  2) Once it's finalised will it be available to add on to JBoss 7.1.x?

Thanks for your help here.

> Solder's Servlet extensions use the default qualifier for certain beans such as ServletRequest. This clashes with built-in beans added in CDI 1.1 and results in AmbiguousResolutionException during deployment.
> I think there are two ways around:
> - to introduce a Solder-specific qualifier so that the "@Default" space is not poluted or
> - detect CDI version and based on that either provide or not provide the overlapping Servlet integration
> ----
> When trying out Weld 2.0.0 Alpha implementation as suggested by Weld developer (Jozef) as per Forum reference, I encountered problems starting application when including seam-persistence 3.1.0.Final in project.
> I have reproduced this in quickstart example in 7.1.0.CR1b with Weld 2.0.0.  The error doesn't happen in 7.0.2.Final and 7.1.1.Final
> Code files and result details for these can be provided if required (can't see how to upload).
