Hierarchical Topics Question

[pchandler]

I have a topic hierarchy say:

        Level1.Leve2.Level3

I would like to subscribe (receive) to all the messages sent to Level2s or Level3s topics (i.e., all message below Level1)

I tried topic subscribers:

     Level1.*     // I only get Level2 messages. Will not receive Level3 messages.

     Level1..   // I only get Level3 messages. Will not receive Level2 messages.

Any Ideas?

Thanks advance,

Peter.

Use a subscriber with Level1.>

The star character will give you only one sub-level of matching while the greater than sign will recursively match all the sub-levels.

Gio,

Thanks! FYI: I didn't see the ".>" notation documented anywhere (i.e., Exploring JMS with FUSE? Message Broker?). That works great.

The current PDF of Exploring JMS withFUSE Message Broker says, on page 63:

You could change these topics to demonstrate a FUSE Message Broker feature

by extending the publish topic to a fourth level, and changing the wildcard

on the subscriber topic from * to >. That expands the wildcard from all topics

at the current hierarchical level to all topics at that level or deeper.

Thanks for the information.
