Jean-Sebastien Delfino updated TUSCANY-67:
------------------------------------------
Fix Version: 0.9x
Version: 0.9x
> ClassLoader issues with SDO
> ---------------------------
>
> Key: TUSCANY-67
> URL: http://issues.apache.org/jira/browse/TUSCANY-67
> Project: Tuscany
> Type: Bug
> Components: Java SDO Implementation, Java Spec APIs
> Versions: 0.9x
> Reporter: Jeremy Boynes
> Fix For: 0.9x
>
> The SDO spec makes extensive use of INSTANCE static fields on the helper
> interfaces which results in a solution that is complex to use and error prone
> in any environment where more than one ClassLoader is involved.
> We should work with the spec group to formulate a model that is easier for
> people to use in today's more complex environments (including build
> frameworks like Maven and Ant, IDE environments like Eclipse, server
> environments like Tomcat and Geronimo, application frameworks like Spring,
> etc. etc.). I will open a sub-task specfically for this.
> We should also ensure that the Tuscany implementation of SDO is easy to use
> in these environments irrespective of what the spec says. We need to define a
> set of APIs that make it easy to handle multiple type spaces in the same JVM
> and/or ClassLoader without requiring the user to play tricks with the
> Thread's context classloader (which they may not even have permission to do).
> We should also ensure any usage of SDO by the SCA runtime uses these APIs,
> reserving the default SDO type space for user applications.
