[Clustering/JBoss] - JGroups mulitcast test program problem, cannot use bind_addr
by timlai
Hi,
I'm new to this forum. I did attempt to search for a topic similar to mine but was not successful. Please let me know if there's a similar topic.
I'm currently attempting to test Multicasting using the JGroups test programs:
org.jgroups.tests.McastReceiverTest
org.jgroups.tests.McastSenderTest
Each of the two boxes I am using have 2 NICs each. Only one of these ethernet cards allows communication between servers (the other is port isolated). So, I must use bind_addr to specify which NIC to use.
However, I'm receiving the following error when attempting to use the programs with bind_addr:
java.net.SocketException: Can't assign requested address
This error also occurs on a simliar environment that only has 1 NIC. I also receive the same error when I specify "-use_all_interfaces" or when using the 1_4 versions of these test programs.
(Note: When not specifying a bind_addr in my 1 NIC environment, there is no error and I am able to send/receive multicast messages correctly. If not specifying a bind adress in my 2 NIC environment, no error is displayed, but no messages are received )
Can anyone tell me why this error is occuring? See below for more specifics about my environment.
OS: AIX
JRE:
java version "1.4.2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2)
Classic VM (build 1.4.2, J2RE 1.4.2 IBM AIX build ca142-20060421 (SR5) (JIT enabled: jitc))
jgroups version: 2.4?
Note: The servers are actually virutalized LPARs, and therefore the ethernet cards associated with the bind_addr IP are also virtual.
Any help you can provide on this topic will be appreciated. Thanks!

[JBoss Seam] - Excadel - RHDS - JBossIDE
by ivanflorentin
I am waiting for RHDS to come out, I've been using ExadelStudio 4.0.4 for a while but returned to Eclipse 3.1.2+JbossIDE 1.6. I've found ExadelStudio to be very unstable, it adds a lot of functionality that I don't need for a price I don't want to pay: huge memory footprint, random eclipse shutdowns, sluggish response.
JBossIDE2.0Beta is also another half finished product and I guess it freezed down to wait for RHDS to come out and integrate all the tools. It will be a huge load of work to come out with a RHDS by july and the impact it will have on the seam comunity and ejb/jee software development in general will be huge too.
I have different versions of eclipse installed in my enviroment with different sets of plugins. I've found that the more usable and stable still remains the JBossIDE 1.6 Bundle with some small additions (SVN for example). I'm using eclipse on linux (gentoo) with sun-jdk-1.5.10.
If somebody has a different experience using ExadelStuddio, it would be nice to post solutions/installation procedure/configurations to avoid those problems.
