[JBoss Remoting Users] - JBoss RMI + Serialization performance issue

The payload uses byte[1024] empty array always. and the object is never serialized. | 2. why byte[] as theres not thing there to serialize in it | 3. Even on using byte[1024] to be sent across using jboss and java rmi we see java rmi is superior on our machines. | | If this is the case then how ar the graphs generated? Or am i missing something very important. Please help. | | -- | ravi | Actually, the byte array gets wrapped in some Remoting objects, which do indeed get serialized. By "Java RMI with Java serialization" I assume you mean the "raw_socket" results, or maybe the "raw_rmi" results, and by "Jboss RMI + socket + Jboss serialization" I assume you mean "socket transport with jboss serialization". Is that right? If so, then I can't explain why you're seeing results different than ours. Who knows? Different machines, different jdk's, etc. By the way, before I released version 2.4.0.GA, I did a lot of testing and tuning, and, in the end, the performance of 2.4.0.GA and whatever the latest 2.2.x release was at the time were very close, within a few percentage points.

Sorry we don't support AS 4.2.x series on user forum any more. If your company can't switch to JBossAS 5.x series then consider our EAP subscriptions.

[jBPM Users] - Re: superstate timer error

by aapthorp

Testing now on 3.2.6.SP1 A bit more digging and I think I'm closer to the problem. It seems the problem is to do with setting a timer on a superstate. I reduced my superstate definition down to one state within the superstate and still the problem occurs. When I replace the superstate with just a normal state then no problem. This seems similar to https://jira.jboss.org/jira/browse/JBPM-2036. Will make a comment there but think this is a separate issue.

[JBoss Tools Users] - Where is a "clear" button?

by piotr.sobczyk

Despite I have JBossTools installed I still use standard "Servers View" more often that "JBoss Server View". Why? Because it has very useful "clear" button that just removes the application from AS and deploys it again - something that programmer need more often that restarting AS. I know I can do it from "JBoss Server View" deleting application in "Explore" window and redeploying it by using Add/Remove option but it takes a lot more time and clicking! Why the heck was "Clear" button not derived from standard "Servers" view like other buttons? And what is "Publish" button for? It seems that most of time it does just nothing.
