[cddlm] Notes of the meeting on 8/3/2005

[Ayla Debora Dantas de Souza - Projeto Ourgrid]

Hi Dejan and all,

we have analyzed the problems with Tomcat and we've concluded that in 
fact our tests were stressing it, because we had at about 30 deployments 
and undeployments of 11MB each, one after the other in a set of 94 
tests. We've reduced each component size verifying common libs from Muse 
that could be removed from each deployed component and it worked. Maybe 
the same problem can happen with Jetty, but we had a meeting yesterday 
and concluded that a lot of code, including unit tests would need to be 
rewritten and we would not be able to have a prototype at the end of 
this month if we make this change. Maybe in a future version we can use 
Jetty.

 In relation to the update of properties, it is working well using Muse, 
we are just implementing more JUnit tests that verify the integration of 
the CDL parser with the module that deals with the update of properties 
in components. We hope to have the first prototype by the end of the 
month, but we fear not to have enough time to assure that  all the tests 
from the Test Plan sent by Steve are passing, because we are suposing 
Muse will actually provide some of the functionality that is demanded 
there and won't give us problems difficult to find as the ones we had 
when the specification needed adjustments.
