[jira] Created: (TUSCANY-1679) PBVInvoker always uses service-side
classloader to deserialize ... also doesn't handle checked/business excs
PBVInvoker always uses service-side classloader to deserialize ... also doesn't handle checked/business excs
------------------------------------------------------------------------------------------------------------
Key: TUSCANY-1679
URL: https://issues.apache.org/jira/browse/TUSCANY-1679
Project: Tuscany
Issue Type: Bug
Components: Java SCA Data Binding Runtime
Affects Versions: Java-SCA-1.0
Reporter: Scott Kurz
First, the easier issue: PBVInvoker doesn't handle faults. For a checked/business exc on a remotable intf, wouldn't we want the exc to get copied too? We wouldn't want some piece of data making its way into the exception to end up unexpectedly modified, right?
Second, I have the problem that the service-side classloader is used to do the copy (e.g.. to do the deserialize in JavaBeansDataBinding.copy() ). While this is what I want when copying the inputs, it is not necessarily what I want when copying the outputs (or the faults which I want to copy above).
I might, for example, want to use a client-side classloader to deserialize the copied objects into. Maybe it wouldn't matter if I was going to do a data transform anyway, but if my outputs/faults are going to go back to the client untransformed, then I'm going to get a ClassCastExc if they're not in the client classloader.
I'm not sure how to fix this...
Note this JIRA, as I could imagine the fixes to these two issues intersecting:

[jira] Commented: (TUSCANY-1679) PBVInvoker always uses

Posted by "Scott Kurz (JIRA)" <tu...@ws.apache.org>.
[ https://issues.apache.org/jira/browse/TUSCANY-1679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12570742#action_12570742 ]
Scott Kurz commented on TUSCANY-1679:
-------------------------------------
The implications of some other discussions we've had on the list suggest that it would be the binding's job to switch classloaders in a case like the one I had in mind. That is, if the client uses CL 1 and the service impl uses CL 2, the binding should not rely on the PBVInterceptor to switch the data into the correct CL.
So I take back stating that as a problem.
I'll see if I can rename the JIRA to focus on the need to copy faults.
