Hi, As I am extending policy support for implementations I realize that we have trouble with aggregating intents and policysets in an JavaImplementation instance. The reason for this is that JavaImplementation instances could be reused in cases where two or more components provide services thro the same implementation.
There is also a JIRA - https://issues.apache.org/jira/browse/TUSCANY-1765that talks of this problem with a nice example. The JIRA has a patch that solves the issue to some extent and not entirely. If JavaImplementaition instances are going to be reused when the same implemenation is used by two or more components, then we need an alternative to store the intents / policy sets so that they are unique for each component. Take for example <composite xmlns="http://www.osoa.org/xmlns/sca/1.0"; name="CompositeX"> <component name="ComponentA" requires="managedTransaction.none"> <implementation.java class="test.DataServiceImpl" /> </component> <component name="ComponentB" requires="managedTransaction.global"> <implementation.java class="test.DataServiceImpl" r/> </component> </composite> Here there is going to be a single instance of JavaImplementation that will be used for both components. But it happens that both these components have different intents defined and these intents will be inherited by the implementations. At the present moment I can only think of storing this info in the Component but I am absolutely uncomfortable with this pollutes the assembly model design for 'Component'. Any other ideas that folks can suggest for this ? Thanks - Venkat
