ActiveMQ command line: publish messages to a queue from a file?

Question

I have an app that uses ActiveMQ, and typically, I test it by using AMQ's web UI to send messages to queues that my software is consuming from.

I'd like to semi-automate this and was hoping AMQ's command line has the capability to send a message to a specific queue by either providing that message as text in the command invocation, or ideally, reading it out of a file.

Examples:

./activemq-send queue="my-queue" messageFile="~/someMessage.xml"

or:

./activemq-send queue="my-queue" message="<someXml>...</someXml>"

Is there any way to do this?

ActiveMQ has a REST interface that you can send messages to from the command line, using, for example, the curl utility.

Here is a script I wrote and use for this very purpose:

#!/bin/bash
#
#
# Sends a message to the message broker on localhost.
# Uses ActiveMQ's REST API and the curl utility.
#

if [ $# -lt 2 -o $# -gt 3 ]  ; then
    echo "Usage: msgSender (topic|queue) DESTINATION [ FILE ]"
    echo "   Ex: msgSender topic myTopic msg.json"
    echo "   Ex: msgSender topic myTopic <<< 'this is my message'"
    exit 2
fi

UNAME=admin
PSWD=admin

TYPE=$1
DESTINATION=$2
FILE=$3

BHOST=${BROKER_HOST:-'localhost'}
BPORT=${BROKER_REST_PORT:-'8161'}

if [ -z "$FILE" -o "$FILE" = "-" ]  ; then
    # Get msg from stdin if no filename given

    ( echo -n "body="  ;  cat )  \
        | curl -u $UNAME:$PSWD --data-binary '@-' --proxy ""  \
             "http://$BHOST:$BPORT/api/message/$DESTINATION?type=$TYPE"
else
    # Get msg from a file
    if [ ! -r "$FILE" ]  ; then
        echo "File not found or not readable"
        exit 2
    fi

    ( echo -n "body="  ;  cat $FILE )  \
        | curl -u $UNAME:$PSWD --data-binary '@-' --proxy ""  \
             "http://$BHOST:$BPORT/api/message/$DESTINATION?type=$TYPE"
fi
