FILE DESCRIPTION
This file contains the JNI C code to allow AWIPS II to interface with MHS.
The main function is Java_com_raytheon_messaging_mhs_MhsMessage_submitMessage,
which gets its name from the Java class that calls it. If the class name
changes at all or is repackaged, then this function must be renamed to match
the new class name.

FUNCTION NAME
Java_com_raytheon_messaging_mhs_MhsMessage_submitMessage
FUNCTION DESCRIPTION
JNI function for building and submitting an MHS message from Java. The
MhsMessage elements (Java) are used to create a MsgObject, which is then
passed to coDDM_createMsg, which in turn executes a DWB transaction to
submit the message to the message request daemon.
submitMessage is called from an instance of the MhsMessage class once all
needed message parameters have been specified and validated. If the call
is successful, 0 is returned. A positive return value indicates a messaging
error. The exact error can be determined from java by looking at the value
of the "result" member. More detailed error text is available by calling
result.getResultText(). A negative return value indicates a problem with
a JNI call that will most likely result in an exception being thrown upon
return to the JVM.
MESSAGE PARAMETERS
showTrace - Boolean value used to print detailed debugging information to
stdout and stderr. Defaults to false.
type - An integer value from 0 to 20 representing the type of message being
sent. See com.raytheon.messaging.mhs.MhsMessageType.java for details.
Defaults to 0.
productId - An optional product ID string of up to 32 characters. If provided
with multiple enclosures, it is only attached to the first enclosure.
verifyAddressess - Boolean value. If true, the addressees are run through a
validation check, but the message is not submitted. Default is false.
addressees - A list of destination addresses. The list can contain any
combination of sites (WFO/RFC) mnemonics, an NCF facility, or special
addresses (e.g. - INET, NWWS, RETRANS, DEFAULTNCF). Every message must
have at least one addressee.
actionCode - Integer code between 0 and 255 inclusive that determines what
action is to be taken by the recipients. The action is determined by
lookup from the text configuration file /awips/ops/data/mhs/rcv_handler.tbl.
This is a required parameter.
subject - Optional text string that is the subject of the message. Can be
up to 129 bytes.
priority - Integer message priority from 0 to 2 with 2 being highest. The
default value is 0.
bodyFile - Fully qualified file name for an optional message body. The
file can be up to 17K in length.
enclosures - An optional list of enclosure files. There is no predefined
limit to the size of an enclosure.
validTime - An optional date string (mm/dd/YYYY[:HHMM]) containing the
absolute time at which the product expires.
timeoutTime - An optional date string containing the absolute time at which
the message will time out if it has not been delivered. The maximum
value is 1200 seconds from the time of submission.
retryCount - An optional integer value containing the number of retries that
will be attempted if the message cannot be successfully delivered.
userId - The optional mailbox name of the recipient. The default is awipsmhs,
which should never be changed since MHS does not look for any other mail
boxes.
LOCAL DATA FILES
None
RETURNS
An integer status code. The Java result code is populated.
