Hi Ruchith,
I have an Axis2 client webapp which determines which
Axis2 Services it should call (according to own
"capabilities" mechanisms) and then spawns threads,
each one calling an Axis2 Service synchronously using
ServiceClient.sendReceive().
Problem is, that sometimes 2 or more services are
located on the same Axis2 server (actually, within the
same ServiceGroup), then - usually the first time I
have to invoke the services since the start of Tomcat
(but sometimes also other times), one service fails,
sometimes more than one. The failure is always on the
Server side.
My security configuration is either "TimeStamp
Signature" (1) or "Timestamp Signatrure Encrypt" (2),
according to the user's request (encryption yes/ no);
of course, the client side and the server side are
using the same security configuration. When I invoke I
invoke either only services of type (1), or of type
(2).
I am sure it is a thread-safe issue, as if I invoke my
services syncronously (by calling Thread.run() myself
i.s.o Thread.start()) I have no problem whatsoever.
I saw a mail on this issue, or a similar one; but i'm
not sure if it was about the client side or the server
side. Is there a new version of Rampart which I can
download and try out?
Hereunder you have 2 stack-traces:
NullPointerExceptions at different methods of
WSDoAllReceiver. The second one (II) happens only with
"Timestamp Signatrure Encrypt" (2), the first one
happens with both configurations.
