Minor Description
According to the documentation, the -E<key> <value> passes the specific configuration parameter to the concrete databinding implementation, e.g. when '-Eb filename' is provided, 'b filename' should be passed to the databinding provider. This doesn't work for JAXBRI. The org.apache.axis2.wsdl.codegen.CodegenConfigLoader correctly saves the value to the configuration map (<'b', 'filename'>), but org.apache.axis2.jaxbri.CodeGenerationUtility searches the configuration map for 'bindingFileName', instead of simply 'b'.
