Is there a way to know the URI of the document being read in StAXArtifactProcessors?

[Vamsavardhana Reddy <c1...@gmail.com>]

Hi,

I am wondering if there is a way to know the URI of the artifact being read
in a StAXArtifactProcessor.  For example, inside of
JEEImplementationProcessor.read(XMLStreamReader reader) method, is there a
way to know the URI of the document that is containing the xml fragment
being read?  The reason in this case is that when archive attribute of
implementation.jee element is empty, the implied value for archive is the
archive containg the composite document defining the component.  If it is
currently not possible, I appreciate if someone can suggest a direction on
what is to be implemented to achieve this.

Hi Vamsi,

In my opinion, it would be difficult to get this information in both the
read/resolve method of the ArtifactProcessor. Similar situation is noticed
in implementation.web and implementation.spring modules and they use
ComponentPreProcessor to overcome this situation. You might need to evaluate
this option for your scenario.

For using ComponentPreProcessor, you might need to implement the preProcess
callback method, which will be called after the resolve phase and before the
build phase of the composite as shown in the samples below.

Samples:
