Creating a message properties context

The message properties context specifies connection information for the underlying Java™ Message Service (JMS) client method call that retrieves the message when you call the ReceiveJMSMessage function.

You pass this context as a parameter when you call the ReceiveJMSMessage function in a policy. The following table shows the properties that you can set in the message properties context:

Table 1. Message Properties Context
Property	Description
`MessageSelector`	String expression that specifies which message in the topic or queue you want to retrieve. The message selector syntax is similar to the contents of an SQL `WHERE` clause and is defined in the JMS specification.
`Timeout`	Specifies the length of time that a message is retained by the JMS delivery system before it expires. Default value is `0`, which indicates an unlimited message lifetime.

You can create an empty message properties context by passing the NewObject function to the ReceiveJMSMessage as a parameter.

The following example shows how to create a message properties context.

// Call NewObject to create the next context
MsgProps = NewObject();

// Assign a message selector that filters the message to
// retrieve

MsgProps.MessageSelector = "color = 'green' AND custom2 = '1234543'";
