------------------------------------------------------------------
Thanks Saminda! It is a great and convenient improvement to support auto.
Following is my understanding about auto implementation. Please clarify if your
understanding is different.
Each time when a request comes, application tries to connect to online schema.
If it fails to connect online schema, validates schema using offline. It's a
combination of both online and offline validation where it falls back to
offline validation in case of connection failure in online validation.
I have modified the build to copy the schema from resources/schema in
commons/gfac-schema module. I think "airavata-gfac-schema-utils" also copied
the schema from the same location. Is there any particular reason such as
possible post processing to copy it from the jar file ?
I'll update the "modules/rest/webapp" and "modules/integration-tests" to use
the same mechanism. I might need some help to test these modules. I have tested
the solution only with XBaya and Airavata Server modules.

> As per the current implementation Schema validations happens online. Internet
> is required to create workflows and execute them, just because of the schema
> validation. This could be an issue, if Internet connection is slow. Proposed
> solution is to introduce offline mode. If offline mode is enabled schema is
> validated against local schema repository. These schema validation occurs on
> both Airavata server and XBaya.
> Schema Repository - Top Level folder schemas on each installation
> Offline configuration - It could be an property on airavata client/server
