EAR/WAR/JAR Architecture

[Elle Atechsy]

Hi All,

Can anyone tell me how code scope within ear & war files? Or, can you tell me where to find the information.

Ex. of what I want to do.

1. Maintain only 1 EAR, but have many WARs that share some common code.
2. Since, multiple WAR files need to use common code, can I place the common code in one WAR's class folder (or is JAR better? if so, where should it be? in the WAR's lib or can it be directly in the EAR, outside of any WARs?)

Thanks for any assistance in Advance.

Thanks,
Keili

In the referencing jar/war's META-INF/MANIFEST.MF add the Class-Path entry

Class-Path: list-of-jar-files-separated-by-spaces
 
E.g.
app1.ear:
  ejb1.jar    Class-Path: util.jar
  util.jar
  webapp.war  Class-Path: util.jar
