Distributed Hashtable and JGroups

[javamann]

Hi all,
I am trying to setup some separate JVM's to both use JGroups for inter-VM communications and to use a Distributed Hashtable. Is there a way to do this without using two Channels?

Thanks

You could use the Multiplexer, check the manual for details

I played around with the Multiplexer for an evening trying to get it to work with both a Distributed Hashtable and a 'Normal' Channel (using UDP) and could not get it going. I have no doubt it is something I was setting up wrong which is why I wanted to check with the group.

Thanks

You can instantiate a multiplexer channel from a client as follows.

STACK_FILE = "stacks.xml";
STACK_NAME = "udp";

JChannelFactory factory=new JChannelFactory();
factory.setMultiplexerConfig(STACK_FILE);
Channel channel = factory.createMultiplexerChannel(STACK_NAME, "foo");
channel.connect("my group");

STACK_FILE must be on your classpath; JGroups provides a file named stacks.xml in its distributable jar. You can use this file or create your own with customized stacks. STACK_NAME refers to the stack within STACK_FILE.

Using the demo code and the manual I had already got that part working. I also got the Distributed Hashtable working using a Multiplexer. I just couldn't get them both working.
