          Use 7.1.1 - we don't accept bugs for 7.1.0.CR1b anymore

            Jesper,

            You mean to sat this is a bug surviving from version JBoss 4.2.3.GA , i thought it is resolved now in jboss version which i am using?

              No managed connections available within configured blocking timeout (30000 [ms])

              That error in all probability isn't a bug in the application server. That error indicates that the application you have deployed is leaking connections.

               

              now i have chnaged size 1(min) - 100(max) still i am getting error several times pls help me out.

              Randomly changing those values isn't going to help. You'll have to first find out why those many connections are open at a given time and if it's expected.

               

              And like Jesper said, use the latest released version (7.1.1).

                Jaiprakash,

                 

                As per my code there is no connection leackage will occure, number of users are currently 5-30 (might be increase in future)at a time thats why i have changed pool size 1-100

                i want only to know whether there is any parameter which is to be modifyed/changed/added apart from pool size to close the issue mentioned in trail mail.

                 

                any way there is no other option to move to latest version
