Spring/EJB integration on TomEE - @Resource problem
Hi,
I have a web application using Spring, and loading a Stateless Ejb by using
ClassPathApplication.
The Ejb is supposed to make a facade for Remoting the application.
The Ejb uses @Resource for referring back to a Spring bean (like
CineplexImpl in the spring integration example). When deploying on Tomee I
get the exception:
"No provider available for resource-ref 'null' of type
'com.myapp.components.IdentityCheckComponent' for 'MyAppStateLessImpl'."
The junit test calling a method on the Ejb works running locally in my IDE.
There is probably some race condition of loading beans and EJB i guess.. ?
Can anybody give me a hint ?
/Morten

just set the OpenEJB.getTransactionManager() returned value as tx mgr in
spring ctx ;)

Hi Romain,
Oh my mistake - you are right it also works for me. I was too fast, and put
a breakpoint with Intellij in the springInCdi() test method. Then when
inspecting the cdi.bean() the prop is null. I assume this is because the
springbean is a proxy. As soon as i read the getProp() i actually get the
expected value.
Ok great. Now i have to figure out how get the transactiontional context
from EJB/CDI to spring...

the comment is to say "don't use cdi to manage @PostConstruct" since spring
already handles it (same for predestroy normally)
i added a property to my test and it works. Do you use a @Spring qualifier?

Hi Romain,
back from vacation and looking at your example. I modified it so that
MySpringBean1 has a String property which is set in app-ctx.xml. Setting a
breakpoint in your testcase, this property seems to be null - not copied
over from spring context to CDI context.. It just seem that a MySpringBean1
instance has been created and injected in MyCdiBean1. I set a breakpoint in
SpringBean create method, and this is apparently not called.. I wonder if
that is the problem. What does your comment 'postconstruct managed by
spring' mean ?

pushed some idea here https://github.com/rmannibucau/cdi-spring-bridge
Note: it uses cdi and works on tomee and should work on weld but it is not
100% CDI compliant (i don't know if CanDI could support it) but since you
were able to use some OpenEJB magic i guess that's not an issue.

Ok - sounds great. I have ckecked-out the openejb project, and will try to
figure out how it can be done. Keep up the nice work - it is much
appreciated .

Easy answer: TomEE is stable for production and used on a lot of projects.
Now the spring-cdi one (a bit longer ;)): what i'd do: i'd write a cdi
producer to create my app context and a disposer to close it. I'd write an
extension to get the application then register all spring beans as cdi
beans.
It should work pretty easily. I'll try to make a poc if i find some time.

Hi Romain,
Thanks for a quick reply!
no reason for not using CDI. I know spring and had to port an old app from
ejb2. So i stumbled over obenejb, and was happy for the easy integration
into unit testing. I thought the "spring integration" example was a nice
approach. I will try using CDI.
I use XA transactions and bitronix. Do you see any problems here concerning
CDI (sorry for my ignorence) ?
I thing I read that CDI/spring mix is a bad idea in e.g. JBoss...
And finally - do you have any working examples for using spring/cdi - more
precisely - is spring booting cdi, or the other way arround. And what about
transactional context.. where does this come from ?
OpenEjb seems great for testing, but what about production ? Is it a stable
solution ?
/Morten.

Re: Spring/EJB integration on TomEE - @Resource problem

yes,
the funny thing is it should work providing openejb in a webapp in
tomcat....but well you'll loose a lot of tomee features.
What i wonder is why using this (now old) integration? why not using an
existing (or one you write since it is easy) cdi extension simply adding to
cdi spring beans? This way you'll be able to @Inject your spring beans
easily.
wdyt?
