When an error occurs while generating a JSR 181 WSDL (Petals / Generate WSDL(s) + jbi.xml), there is no error message nor report and the generation just fails (no file is generated).
Example: a method annotated @WebService that receives a class (complex type) as argument.
JAX-WS specifies that the class passed as arguments requires a constructor with no argument : when such a constructor is present, the generation works fine... but when it's not present, the generation fails, no file is produced, and no error log.
