Using underlying messaging system

Our implementaion can support various underlying messaging systems. Curently, NaradaBrokering messaging system (version 0.98rc1), openJMS (version 0.7.6.1) and activeMQ (verions 3) are supported. You may experience problem if you use other versions.

Please also note, since we are currently using our own message filtering for simple topic filtering and XPath filtering. These underlying messaging systems may experience problem since they are not tested with each latest release.

1. To use embeded activeMQ as underlying messaging system (optional)

The easiest way to start the broker is using the embeded activeMQ as the underlying messaging system. This is the way we are currently using in our LEAD project.

You don't need to install activeMQ or start activeMQ server. The activeMQ jar file is included in the downloaded zip file. To start the server, run the following command from WSMG_Home/bin directory:
java wsmg.Server -port 12345 -carrier activeMQ

Note: "activeMQ" is specified as carrier.

You need to run from bin directory since I use "../config/db.config" to specify the config file location. You can also modify startServer.sh in the bin directory if you are running in UNIX.

2. To use openjms as underlying messaging system (optional)

First, start openJMS (Please see user guide for openjms on how to install and start openjms server. It is very easy to install.). You MUST start openjms BEFORE runing the command.

Then, run the following command from WSMG_Home/bin directory:
java wsmg.Server -port 12345 -carrier openJms -carrierLocation "rmi://rainier.extreme.indiana.edu:1099"

Note: "openjms" is specified as carrier.

You need to run from bin directory since I use "../config/db.config" to specify the config file location. You can also modify startServer.sh in the bin directory if you are running in UNIX.

3. To use NaradaBrokering as underlying messaging system. (optional)

First, start NaradaBrokering. You MUST start NaradaBrokering BEFORE runing the command. See user guide for NaradaBrokering on how to start NaradaBrokering.

Then, run:
java wsmg.Server -port 12345 -carrier narada -carrierLocation "rainier.extreme.indiana.edu:3045"
 Note: "narada" is specified as carrier. The carrierLocation specifies the location of the NaradaBrokering. port is the port that the broker is listening for requests.
