Examples

This example shows the use of multiple JMSSource operators with different parameter combinations. 


composite Main {
graph
// JMSSource operator with the default etc/connections.xml(relative to the application directory)
// connections document
stream <int32 id, rstring fname, rstring lname>
MyPersonNamesStream  = JMSSource()
{
	param
		connection : "amqConn";
		access     : "amqAccess";
}

// JMSSource operator with fully qualified name of connections.xml
stream <int32 id, rstring fname, rstring lname>
MyPersonNamesStream = JMSSource()
{
	param
		connectionDocument : "/home/streamsuser/connections/JMSconnections.xml";
		connection         : "amqConn";
		access             : "amqAccess";
}

// JMSSource operator with optional output error port specified
(stream <int32 id, rstring fname, rstring lname> MyPersonNamesStream ;
stream <rstring errorMessage> ErrorStream) = JMSSource()
{
	param
		connection : "amqConn";
		access     : "amqAccess";
}

// JMSSource operator with optional initDelay and reconnectionPolicy specified
stream <int32 id, rstring fname, rstring lname>
MyPersonNamesStream = JMSSource()
{
	param
		connection         : "amqConn";
		access             : "amqAccess";
		reconnectionPolicy : "NoRetry";
		initDelay          : 10;
}

// JMSSource Operator with optional period and reconnectionPolicy specified
stream <int32 id, rstring fname, rstring lname>
MyPersonNamesStream = JMSSource()
{
	param
	connection         : "amqConn";
	access             : "amqAccess";
	reconnectionPolicy : "InfiniteRetry";
	period             : 1.20;
}

// JMSSource operator with reconnectionPolicy specified as BoundedRetry
stream <int32 id, rstring fname, rstring lname>
MyPersonNamesStream = JMSSource()
{
	param
		connection         : "amqConn";
		access             : "amqAccess";
		reconnectionPolicy : "BoundedRetry";
		reconnectionBound : 2;
		period: 1.20;
}
