Hi,
I have tried to realize client which can invoke service several times.
And I have determined that some resources(threads on service side, tcp
connections and memory on both side) stay in use after service invocation have
completed. I'm using axis2_http_server.exe from version 0.92.
Could you explain me how I have to free resources correctly, please?
Examples which were modified in order to have multiple invocation are applied
below (mtom and echo).
---
Best regards,
Evgeniy
