Thanks for the reply. I've modified the files and attached the xsd,
xjb and sample test file.
The Common.xsd and Common.xjb is in dir libObject1. Main.xsd and
Main.xjb is in dir libObject2.

The namespace in common.xsd is http://www.w3.org/2001/XMLSchema,
because i was getting Adapter1 error, which it was trying to reference
from w3. I used this link to fix it.
https://jaxb.dev.java.net/guide/Customizing_Java_packages.html#Tip__get_rid_of_the_org_w3__2001_xmlschema_package

I'll also try out the validation. Let me know if i could give
additional information.

Regards,
Jyoti
