[Clustering/JBoss] - Re: Clustering begginner..please HELP
by sreejava
Hi
As per you direction i ve verified my logging level. And it was already set to INFO in the log4j.xml.
But still my log file is a combination of INFO and DEBUG.
As it failed i started picking up the lines with logging level 'INFO' from my server.log files.
Then i could see the following lines which i copied here.
THANK YOU
I am still confused with my belief of clustering so i repeat
======================repetition=============
i do have a belief that, if clustering is enabled; and if one of the server(s1) goes down,
then the other(s2) will serve the requests coming to s1.
Am i correct? Or is that true only in the case of "Failover clustering".
If it is correct, what are all the things i have to do to achieve it?
============================================
What you think my next step to be? Is it Failover clustering? If so, boss, please give me some clues.
I ll work on that. Kindly help me. Becoz, i could nt see theses informations in any book or web tutorial. Or atlest suggest me some good material if you know. All the materials i saw were explaining about the theoretical aspects only.
please help...........
with regards
sreevals

[JBoss Seam] - Re: DataModel
by lightbulb432
That makes sense (and works). Thanks.
I have two DataModelSelections for two DataModels on the same SFSB. When I select one table, the DataModelSelection for that gets properly injected, but the other gets injected with null values (and an id of 0).
Why is something (albeit a null value) getting injected into the DataModelSelection that I didn't select? This is causing problems when I do a #{empty selectedEntity} to check whether the OTHER entity (the one I didn't select) has been injected.
It returns FALSE because it has been injected when it shouldn't have been!
Why is a "null entity" getting injected into DataModelSelection? Is this expected behavior? If not, what might be causing it?
