Would like to hear from people about their experience with java clustering (ie. implementing HA solutions). aka . terracotta, jgroups etc. It doesn't have to be web apps. Experience writing custom stand alone servers would be great also. UPDATE - I will be a bit more specific -> not that interested in Web App clustering (unless it ca...

I have seen this question (answer: JGroups) and I'm thinking about implementing something with JavaGroups or straight RMI but speed is of the essence. I'm not sending large amounts of data around (content of MIDI Messages, so 3 bytes each, no more than say two messages every three milliseconds) and this will be all on the same machine. ...
Hi, We are getting the following error in the log files. Need to know why this error is thrown and what effect it has. We are using JGroups 2.7.

Actually all of them seem to end up in the xmit_table, and a another dump from a few hours later indicates that they never intend to leave either...

Hi, I have a website running with JBoss 4.2.2 on an existing Red Hat server. I'm setting up a second server so as to have a clustered pair (which will then be load-balanced). However, I can't get them to cluster successfully. The existing server starts up JBoss with: run.sh -c default -b 0.0.0.0 (I know the 'default' configuration d...
