Hi,
I have a web service which is running under the Tomcat container.
Tomcat creates a new instance of
this web service with each incoming simultaneous connection. The problem
I am having, is that my web service
calls a hardware device which can only handle one query at a time. If I
have 5 instances of my web service
all querying it at the same time, it hangs. I need to implement some
sort of serialization such that only one
request is processed from each instance at a time. Is it possible to
serialize between service instances, which
have been created by tomcat? Is there some external library to tomcat
shared memory object which will
allow me to do this? I have had a look around the web, but I'm not
really sure where to start. I've come
across messaging solutions, but all these seem to be targeted towards
serialization between services located
on completely different tomcat instances (JMS).
Cheers
Tom
