How does Seam scan for its components?

[alartin]

Hi all,

  I hope to write some customized components to be shared by all of my Seam projects and make them as built-in components. Say, I package them as a customized-seam.jar. In my other Seam projects(EAR jar) I reference this jar file.

myproject.ear
          |_ lib
               |_ customized-seam.jar
          |_ jboss-seam.jar
          |_ myprojectejb.jar
          |_ myprojectweb.war

But this design does not work.

The other ideas are:
1. bundle the customized-seam.jar into jboss-seam.jar
2. put it under myprojectweb/WEB-INF/lib
3. put it under the myproject.ear like jboss-seam.jar and declare it as an EAR module

My questions are:

1. why does Seam not scan the .ear/lib directory? I check the Seam's Initialization class and find warClassDirectory, warLibDirectory, hotDeployDirectory, warRoot, etc except earLibDiretory

2. Is it possible to let Seam scan components under .ear/lib directory and how?
3. What is the best practice for this situation? BTW, I found a Seam extension project called XSeam and users have to put its jar under WEB-INF/lib directory but I hope I can put it under ear project's lib directory.

Thanks a lot!

Place an empty seam.properties in your archive and Seam will scan that file. We tested it with a separate Jar, but I think an ear should work also.

Seam considers every item on the classpath, but it only scans for components from those items with a marker like seam.properties.
