How to replace file inside JAR which is inside RAR in Maven EAR build

Question

I'm trying to build an EAR that consist of some resource adapter (let's call it resource.rar) and some other JARs. resource.rar contains several JARs: - resource-api.jar - resource-impl.jar - resource-ejb.jar - others...

What I need to do is to replace persistence.xml that is in the following path: my_application.ear/resource.rar/resource-ejb.jar/META-INF/persistence.xml with some filered resource. My goal is to change properties like:
property name="hibernate.hbm2ddl.auto"
property name="hibernate.dialect"

maven-ear-plugin allows to unpack artifacts but as far as I know it is possible only for one level structure.

Have a look at the TrueZip Maven plugin.
