Re: [seam-dev] Seam REST and WELD-001303 No active contexts

The below test case impl doesn't track any sessions and the conversation only survives per method call. So the lifecycle to it isn't proper :) It's nothing more than a workaround. It'd be better to have support for ConversationScope in Seam REST. Maybe I'm doing something wrong here, but my code case is as simple as: 1) PU produces a ConversationScoped entity manager in Seam Persistence 2) The REST service makes a call to a Stateful ConversationScoped bean, in which invokes the ConversationScoped PU 3) REST service beans are used to accommodate natural REST crud on top of a JSF page. That's all there are to it. The deployment includes solder, faces, international, persistence, transaction, security, conversation-{weld and spi} and rest. I'm investigating ways to make a hybrid model that uses JSF and REST. So far so good, except for the aforementioned.

If don't have some way of doing that you'll end up possibly creating a new session / conversation with each request because it isn't tied to the same session.
