[jira] Created: (TUSCANY-1460) SDO databinding's SDO metadata is
scoped in a classloader different from the webapp classloader created by
the embedded tomcat (ClassCastException w/ sample-helloworld-sdo)
SDO databinding's SDO metadata is scoped in a classloader different from the webapp classloader created by the embedded tomcat (ClassCastException w/ sample-helloworld-sdo)
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: TUSCANY-1460
URL: https://issues.apache.org/jira/browse/TUSCANY-1460
Project: Tuscany
Issue Type: Bug
Components: Java SCA Data Binding Runtime
Affects Versions: Java-SCA-Next
Reporter: Raymond Feng
The embedded Tomcat creates web app classloader for the thread handling the incoming HTTP requests. As a result, the scope for SDO HelperContext is different from the classloader when the SDO metadata is introspected during the contribution processing.
We probably need a better scoping for SDO metadata than the classloader. Contribution might be used as the key (we can even support import/export).

Jean-Sebastien Delfino commented on TUSCANY-1460:
-------------------------------------------------
The problem is that our embedded Tomcat server does not set the correct classloader on the Tomcat StandardContexts it creates. I am fixing it.
