# Example: jms_set_message_property

This example shows using jms_set_message_property to set up for queuing a message.

    long t=1;
    char *chr;
    t=time(&t);
    t = t + 100000;
    chr = (char*)malloc(20, sizeof(char));
    sprintf(chr,"%d",t);
    jms_set_message_property("JMSExpiration","JMSExpiration", chr);
    jms_set_message_property("JMSMessageID","JMSMessageID", "-JMSMessageID-");
    jms_set_message_property("JMSPriority","JMSPriority", "9"); //0-9, 4 is default
    jms_set_message_property("JMSRedelivered","JMSRedelivered", "true");
    jms_send_message_queue("sending message 1","RecordedBuffer1", "TestJMSQueue");

    This example shows setting the JMSCorrelationID property, and then sending/receiving a message.
    jms_set_message_property("step0: set the JMSCorrelationID",
        "JMSCorrelationID",
        "VuserID-{VuserID}");

    jms_send_receive_message_queue("step1: send and receive message",
        "Test Message",
        "weblogic.jms.inqueue",
        "weblogic.jms.outqueue");

    lr_message(lr_eval_string("{JMS_message}"));

    This example shows how to set a custom selector for a subscription. Any message whose flag value is set to "no" is received on a specific topic.
    jms_set_message_property("selector_step", "JMSSelector", "flag = \'no\'");

    jms_subscribe_topic("subscribe_step", "subscription_1", "testTopic");

    jms_publish_message_topic("publish_step", "message to publish", "testTopic");

    jms_receive_message_topic("receive_step", "subscription_1", "testTopic");

    lr_output_message(lr_eval_string("message : \n{JMS_message}\n"));

    This example shows how to filter messages received for a subscription by correlation ID. Only messages whose correlation ID is 4566636 are received.

    /* This call sets the filter for the all messages received for this subscription. */

    jms_set_message_property("prop","JMSCorrelationID","4566636");
    jms_subscribe_topic("subcribe_step", "subscription_1", "testTopic");

    /* This call sets the correlation ID for the next message to be sent. */

    jms_set_message_property("prop","JMSCorrelationID","123");
    jms_publish_message_topic("publish_step", "This message matches Correlation ID 123", "testTopic");

    /* This message is not received because the correlation ID does not match the filter. */

    jms_receive_message_topic("receive_step", "subscription_1", "testTopic");
    lr_output_message(lr_eval_string("message: {JMS_message}\n"));

    /* This call sets the correlation ID for the next message to be sent. */

    jms_set_message_property("prop","JMSCorrelationID","4566636");
    jms_publish_message_topic("publish_step", "This message matches Correlation ID 4566636", "testTopic");

    /* This message is received because the correlation ID matches the filter. */

    jms_receive_message_topic("receive_step", "subscription_1", "testTopic");
    lr_output_message(lr_eval_string("message: {JMS_message}\n"));
