Some of the namespaces used in WSIT configuration file doesn't have schemas published

In particular, the following two namespaces:

xmlns:sc="http://schemas.sun.com/2006/03/wss/server"
xmlns:wspp="http://java.sun.com/xml/ns/wsit/policy"

It is customary to publish a schema in those URLs. JAX-WS and JAXB both does this.

Start by tracing the WSIT configuration references for the sc and wspp namespaces, using the two namespace URLs and the linked source issue as context. Inspect the repository resources that define or package these namespaces. Done means schemas are published at both requested namespace URLs and the configuration references resolve to them.
