Re: [Resteasy-developers] RESTeasy and Hot Deployed Seam Components

Regan,

 

Seam support is something that I'd like to get in at some point, and I
did have it working in some of the very early versions of RESTEasy. I
doubt we'd be able to get Seam support in 1.0, but it's on my radar for
a future release. 

 

To answer your question about the use of a Seam-managed EntityManager in
a Resource: you've have to be able to have the Resource double as a Seam
component otherwise you will get an NPE. Once I get the MultipartData
support wrapped up, I'll have a look at the class loader stuff and
proper Seam integration.

Subject: [Resteasy-developers] RESTeasy and Hot Deployed Seam Components

 

Hello,

I'm trying to get RESTeasy to work with Seam hot-deployed components,
but I can't figure it out. Because this is a mailing list, I will copy
my posting from seamframework.org
<http://seamframework.org/Community/HotDeploymentEntityManagerAndRESTeas
yProblem> . If someone can give me some hints,  I will post them to the
seam forum as well.

My project is using seam components, no EJBs. So all my action classes
go to WEB-INF/dev and therefore are not visible for classes deployed
outside, because of the custom seam class loader, right? 

 

So when I want to use a Seam and JAX-RS annotated action class (@NAME,
@PATH at Class, and @GET at method) with RESTeasy, it fails to find it,
because it scans in WEB-INF/classes by default. Even when I configure
RESTeasy with context param resteasy.resources including the fully
qualified class name, I get a ClassNotFoundException. 

 

Ok, then I tried to put the action class in model directory, changed
package name and corresponding resteasy.resources param. Now RESTeasy
finds the class and tries to process the @GET marked action method, but
it fails with an NPE when using the injected EntityManager. I guess
there is no DI happening? But I want to load the RESTeasy/JAXB annotated
entity... 

 

So, the questions are: 

 

Is there a way for RESTeasy to load seam components in WEB-INF/dev? 

 

If not, can I use the @In Annotation for the EntityManager to get access
to seam managed persistence context in RESTeasy? 

 

All the examples I found are using EJB/Seam components, not regular seam
beans. Anyone got this to work? Thanks for any pointers...

 

Regen


PS: I'm using RESTeasy Beta 5, Seam 2.0.2.SP1, JBoss 4.2.2.GA
