hi...
thanku so much for giving me some useful source..
bu tnow i got a new problem..
in the ConnectionFactory Implmentation class...
fot the getConnection() method ..i have written
getConnection() {
ConnectionImpl obj =*null*;
obj= (ConnectionImpl)cm.allocateConnection(mcf, *null*);
return obj;
}
mcf - managed connectionfactory reference
cf-connectionfactory instance got through lookup
but when i try to invoke a cf.getConnection() method i ma getting the
following exceptio(also the ConnectionFactory is not null,i mean lookup is
sucessful):
RAR5117 : Failed to obtain/create connection from connection pool [
myrapool7 ]. Reason : null
exception
