Servicemix-components plus lwcontainer

Wed, 06 Sep 2006 13:03:45 -0700

Sorry to hijack this thread, but I was hoping for clarification of the last statement made in the quoted thread. I have been building an application that consists of several home-grown servicemix 'pojo' components configured directly in servicemix.xml, several binding components from servicemix-component and an 'extension' framework based on additional components hot-deployed against the lwcontainer.
I've never analyzed the class loading behavior in this arrangement myself, but am I to understand that this is a non-optimal configuration? Can you elaborate on the consequences of my current design, and help me understand what I've done wrong if this is not a best-practice? 

Thanks in advance for any assistance.

B.J.

The reason is that servicemix-components is not put anymore in  
the ./lib

folder, because it forces all lw components

dependencies to be loaded from the server classloader when you  
deploy a SU

on the lw container.
If you don' t use the lw container, feel free to add this jar in
./lib/optional.
