Custom DynamicDeployer
Hello,
The OpenEJB's ConfigurationFactory supports providing a custom
DynamicDeployer to it. Does Tomee provide any means to configure such a
custom DynamicDeployer, or is this completely hidden?
Regards,
Lazar

Thanks Romain,
I cannot make it work without explicitly defining a Resource somewhere, now
I will give a try to the observers.

The properties provider injects the serviceid if there. That said an
observer is surely the easiest to do what you want.
You can openejb @Observes Object 1nd declare it as a Service in tomee.xml

Re: Custom DynamicDeployer
Posted by Lazar Kirchev <la...@gmail.com>.
a serviceId field in the create method of the service provider? I tried
this but the actual parameter value which was passed was an empty string.
In the AutoConfig.autoCreateResource() the custom provider is correctly
discovered, but then nowhere in the code the name from the ResourceRef is
passed to the logic which creates the ResourceInfo (line 2045) and then the
resource itself (line 2048). The code lines are from 7.0.0 branch.
Probably I am doing something wrong. I can attach a very simple service
provider and application which reproduce this behavior.

Re: Custom DynamicDeployer

I need to create resources on the fly based on ResourceRefs, without any
resource definition in resources.xml or context.xml. I could not find how
to achieve this with the current APIs. In this case the template API does
not help, as it needs an existing resource. It is similar with the
properties providers. With service providers if there is no resource
defined the attributes from the ResourceRef are not passed to the service
provider and in my case these attributes - e.g. the name - are important
for the creation of the particular instance. Having a custom
DynamicDeployer, which could access the resource refs and create/modify
resources before calling the service providers could help.

Re: Custom DynamicDeployer

Short answer is no
what do you want to achieve, there are events to change the app model
before the deployment if that's the goal (look for BeforeApp*)
