33 * Apex parameters for JMS as an event carrier technology.
35 * <p>The parameters for this plugin are:
37 * <li>initialContextFactory: JMS uses a naming {@link Context} object to look up the locations of JMS servers and JMS
38 * topics. An Initial Context Factory is used to when creating a {@link Context} object that can be used for JMS
39 * lookups. The value of this parameter is passed to the {@link Context} with the label
40 * {@link Context#INITIAL_CONTEXT_FACTORY}. Its value must be the full canonical path to a class that implements the
41 * {@code javax.naming.spi.InitialContextFactory} interface. The parameter defaults to the string value
42 * {@code org.jboss.naming.remote.client.InitialContextFactory}.
43 * <li>providerURL: The location of the server to use for naming context lookups. The value of this parameter is passed
44 * to the {@link Context} with the label {@link Context#PROVIDER_URL}. Its value must be a URL that identifies the JMS
45 * naming server. The parameter defaults to the string value {@code remote://localhost:4447}.
46 * <li>securityPrincipal: The user name to use for JMS access. The value of this parameter is passed to the
47 * {@link Context} with the label {@link Context#SECURITY_PRINCIPAL}. Its value must be the user name of a user defined
48 * on the JMS server. The parameter defaults to the string value {@code userid}.
49 * <li>securityCredentials:The password to use for JMS access. The value of this parameter is passed to the
50 * {@link Context} with the label {@link Context#SECURITY_CREDENTIALS}. Its value must be the password of a suer defined
51 * on the JMS server. The parameter defaults to the string value {@code password}.
52 * <li>connectionFactory: JMS uses a {@link javax.jms.ConnectionFactory} instance to create connections towards a JMS
53 * server. The connection factory to use is held in the JMS {@link Context} object. This parameter specifies the label
54 * to use to look up the {@link javax.jms.ConnectionFactory} instance from the JMS {@link Context}.
55 * <li>producerTopic: JMS uses a {@link javax.jms.Topic} instance to for sending and receiving messages. The topic to
56 * use for sending events to JMS from an Apex producer is held in the JMS {@link Context} object. This parameter
57 * specifies the label to use to look up the {@link javax.jms.Topic} instance in the JMS {@link Context} for the JMS
58 * server. The topic must, of course, also be defined on the JMS server. The parameter defaults to the string value
60 * <li>consumerTopic: The topic to use for receiving events from JMS in an Apex consumer is held in the JMS
61 * {@link Context} object. This parameter specifies the label to use to look up the {@link javax.jms.Topic} instance in
62 * the JMS {@link Context} for the JMS server. The topic must, of course, also be defined on the JMS server. The
63 * parameter defaults to the string value {@code apex-in}.
64 * <li>consumerWaitTime: The amount of milliseconds a JMS consumer should wait between checks of its thread execution
65 * status. The parameter defaults to the long value {@code 100}.
66 * <li>objectMessageSending: A flag that indicates whether Apex producers should send JMS messages as
67 * {@link javax.jms.ObjectMessage} instances for java objects (value {@code true}) or as {@link javax.jms.TextMessage}
68 * instances for strings (value {@code false}) . The parameter defaults to the boolean value {@code true}.
