Weld + Tomcat + Jerset: WELD-001304: More than one context active for scope type javax.enterprise.context.RequestScoped

niqueco Aug 13, 2018 1:28 PM

Hi, I'm new with all this. I'm trying to set up a project using Jersey over Tomcat. By adding Weld to the mix I was able to have a @Context ServletContext injected. But I wanted more: I wanted to inject my own objects, so I added an empty beans.xml (? - saw that somewhere) and... bang! I got this exception:

(I'm not doing anything with Weld directly, I'm not manually creating any context or something).

If I put a breakpoint at the time of the crash I get that the contexts (the ctx variable at the point of the crash) are instances of this classes:

org.jboss.weld.context.bound.BoundRequestContextImpl (this first one isActive and produces the crash)
org.jboss.weld.context.unbound.RequestContextImpl
org.jboss.weld.context.http.HttpRequestContextImpl

I think what I'm trying to do is pretty simple, it shouldn't be so hard. I don't know if I'm hitting a bug or if I'm doing somethin wrong.

Thanks!

Hi,

first of all, I guess you glanced at how to use Weld with Tomcat at docs - link.

Then, assuming this part is correct, where does @Context ServletContext come from?
It doesn't look like CDI annotation - with CDI you need to use @Inject ServletContext to get hold of the built-in bean.

Now, I don't know much about Jersey, but it looks like they are internally using hk2, which is a DI implementation (no to be confused with CDI implementation), I suppose that may cause some clashes as well?

Last but not least, I stumbled onto this SO question where someone set up just what you are after, Tomcat, Jersey and Weld, so maybe you will want to give it a glance.

Yes, I did glance Weld's documentation. @Context is an annotation defined in JAX-RS. It's an annotation that requests the injection of a number of possible types (like ServletConfig). It's Jersey's job to do something correct with it, possibly calling Weld or something.
Yes, they does use HK2, but they also support Weld with an extension I've added.
I had seen that SO question, sadly there's not a lot of information.
I think I'll need to take this problem to Jersey's developer. I'll ask around.
Thanks!
