Examples of org.jgroups.JChannel.connect()

org.jgroups.JChannel.connect()
Connects the channel to a group. If the channel is already connected, an error message will be printed to the error log. If the channel is closed a ChannelClosed exception will be thrown. This method starts the protocol stack by calling ProtocolStack.start, then it sends an Event.CONNECT event down the stack and waits to receive a CONNECT_OK event. Once the CONNECT_OK event arrives from the protocol stack, any channel listeners are notified and the channel is considered connected. @param cluster_name A String denoting the group name. Cannot be null. @exception ChannelException The protocol stack cannot be started @exception ChannelClosedException The channel is closed and therefore cannot be used any longer.A new channel has to be created first.
