Re: [rules-users] [droolsflow] Jmeter Test
Is it possible that your tests start before the task service has been
set up completely (notice that it could take a few seconds to set up the
users etc.). Try adding some more delay before starting the tests.

Hi All
I Make a test with Jmeter (http://jakarta.apache.org/jmeter/) to
stress my
flow. I Created a Thread Group, to execute 1000 simultaneous users
for start
the flow.
I had the follow trouble:
The First users that try to started the process, received this
execption:

After some users, the process starts normal. The problem occur only
for the
first users. I Believe that problem is from MinaTaskServer tha was
not
started correctly. (Just start, after some calls).
I used to start MinaTaskServer the follow code (This code is inside a
Jboss
- MBean):
*
*
*TaskService taskService = new TaskService(*
* this.entityManageSessionFactory,
SystemEventListenerFactory
*
* .getSystemEventListener());*
* server = new MinaTaskServer(taskService);*
* Thread thread = new Thread(server);*
* thread.start();*
* Thread.sleep(5000);*
could anybody help me?
Thanks
