We should avoid writing to stdout/stderr and use jboss logging instead.

Currently the schema parser writes error messages to stdout when an imported schema cannot be resolved.

[Error] CustomTypeArrays.xsd:5:99: src-resolve: Cannot resolve the name 'ns2:HelloObj' to a 'type definition' component.

This message wil probably go away once the schema parser uses a resolver that can handle multiple included schemas in wsdl.
Then this issue becomes obsolete.
