I have found one work around for this problem but i would like to ask one
question that if in my WAR file if i put all WEB-INF\classes files in a jar
and put it under WEB-INF\lib directory and clean my classes directory than I
can't accesss services. is it bug in tuscany or i can't access like this
way. This is the problem with weblogic, I have tested this scenario with
Tomcat where it was working fine but result was as expected i can't access
service from lib directory.
Hi Nishant,
I created a WAR similar to what you're describing (moved the classes to
a JAR placed in the lib directory) and I think am able to reproduce the
problem you're seeing, on Tomcat as well. Here's the exception I'm
seeing. Could you please confirm that this is the exception you're seeing?
Thanks.
