Re: [jboss-as7-dev] JBoss Modules: can I dynamically add dependency?
Unfortunately this premise is flawed from the start: if you had two
apps, each requiring a different JSF implementation, this idea could
never work.
In any case you cannot change the dependencies of a static module at
runtime. Normally when multiple implementations are available you would
use reflection to instantiate the implementation you need. If this is
not possible then you'll need a separate module for each implementation
type.

<module name="javax.api"/>
<module name="org.jboss.as.web"/>
<module name="javax.servlet.api"/>

Inside a DeploymentUnitProcessor, the module above is added to the
ModuleSpecification along with the module for the selected JSF
implementation. The problem I have is that the JSF Injection code is
the same for any Mojarra implementation. But to support multiple
implementations I need to declare a separate jsf-injection module with a
hard-coded dependency on each implementation installed.
If I could create a module dynamically and dynamically add its
dependencies then there would be no need to create more and more modules
containing the same jsf-injection jar.
I've been looking at the JBoss Modules API and I don't see how to do
this. Is it possible?
