I'm new to Seam and liking the look of the Persistence mechanism. For the view/presentation side I am using a library which is based around HttpServlet i.e. not JSF based.
I'm using JBoss AS 7 and Seam 3.1.0.Final
When I put these together with my Servlet library and get to the first method marked "@Begin" I get an exception because I don't have a ConversationScoped Context defined. I confess, I half expected something like this.
org.jboss.weld.context.ContextNotActiveException: WELD-001303 No active contexts for scope type javax.enterprise.context.ConversationScoped
I tried a variation of the suggestion in <http://stackoverflow.com/questions/4828504/how-to-inject-conversationscoped-beans-in-a-servlet> but found that no ConversationContext was set (null pointer).
Again I half expected this not to work, as I clearly haven't set anything in the http headers for the "cid" part.
I've also tried following some of the setup for Seam Booking example it uses
and hence starts to drag in faces stuff - I get this compiled but then get a Weld Deployment Exception
org.jboss.weld.exceptions.DeploymentException: WELD-001409 Ambiguous dependencies for type [ELContext] with qualifiers [@Default] at injection point [[parameter 1] of [c
onstructor] @Inject public org.jboss.solder.el.Expressions(ELContext, ExpressionFactory)]. Possible dependencies [[Producer Method [ELContext] with qualifiers [@Any @Default] decla
red as [[method] @Produces org.jboss.seam.solder.el.ELContextProducer.createELContext()], Producer Method [ELContext] with qualifiers [@Any @Default] declared as [[method] @Produce
So my questions are:
1) Am I trying to do something that Seam Persistence is not designed for? I see lot's of references which all point to JSF. Is it intimately linked with JSF?
2) Is there parts of the Seam Library that I can use at App Startup, Session Startup and/or on each Request so that ConversationContext (and other required Contexts) are set?
I can post other stuff from my application, but I'm not looking to get anyone to debug my app - just a pointer to a good example of Seam Persistence without JSF and/or a good manual.
