These are the faults that can be thrown by the RequestInterface. Note that no bean/stub is generated for faults by Axis, a matching Java Exception type must be introduced. Permission has been denied for some reason. The message may contain more information. If the request is malformed in some way (but which still matches the XML schema), then this fault will be thrown. The message element contains details of what was wrong. If no tool of those specified is available for use, this exception will be thrown. If the characteristic specified is not available this fault is thrown. ToolUnavailableException may be thrown instead if the sink PMP doesn't support this characteristic.. This fault occurs if the time specified in the request is not available. The "when" indicates a preferred new time slot.
