I carried out the test as rram75 had suggested and ended up getting timed out
exception with jboss.
I also tried hitting weblogic server with the same code and it did work
perfectly fine. One thing i did try was to print the thread name to see, whether in
case the call to the server was synchronized and i was right. Web logic did
synchronize the calls to the naming server.
I debugged the jboss naming client code and modified the static Naming
getServer(String host, int port, Hashtable serverEnv) throws NamingException code to
be synchronized and that took care of the socket timeout exception that was happening
before. THe reason for the socket exception was that at times, the Naming reference
was null and it then tried to do a multicasting to find the server. This was the place
where a socket time out happened.
I did a few testing and benchmarking with weblogic against jboss and
found that jboss was faster with smaller amounts of hits to the server. ie, if i had
100 threads that hits the server using jndi , jboss would always beat weblogic in
retrieving the objects. But for higher threshold values, weblogic beats jboss. This is
probably due to the way it attempts reconnection in lookup function of
org.jnp.Interfaces.NamingContext .java file. Augmenting the backlog also didnt help
jboss in significantly reducing the time in retrieving objects using Jndi.
I am wondering if i had to do any thing else to make the jndi lookup faster?.
