Subject [jira] Updated: (DERBY-2559) recreating a datasource using javax.naming.Reference from a ClientDataSource40 fails
Date Mon, 18 Feb 2008 09:06:35 GMT

     [ https://issues.apache.org/jira/browse/DERBY-2559?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Kristian Waagan updated DERBY-2559:

    Attachment: derby-2559-3b-documentation.diff

Thanks for looking at the patch Knut Anders.

'derby-2559-3b-documentation.diff' adds a throw clause to the JavaDoc and corrects an invalid
reference. I also refreshed the patch after applying patch 2a.

Committed 'derby-2559-2a-defenses.diff' to trunk with revision 628647.
Committed 'derby-2559-3b-documentation.diff' to trunk with revision 628654.

The previous code failed to create data sources when running with Java SE 6.
This suggest the patches could be backported to branches 10.2 and 10.3.
Patches 1 and 2 apply cleanly, the documentation patch (3) does not.

>         Attachments: derby-2559-1a.diff, derby-2559-2a-defenses.diff, derby-2559-3a-documentation.diff,
> Consider the following code snippet from test DataSourceReferenceTest:
> --------------------
>         Referenceable refDS = (Referenceable) ds;
>         Reference dsAsReference = refDS.getReference();
>         String factoryClassName = dsAsReference.getFactoryClassName();
>         ObjectFactory factory = 
>             (ObjectFactory) Class.forName(factoryClassName).newInstance();  
>         Object recreatedDS = 
>             factory.getObjectInstance(dsAsReference, null, null, null);
> ---------------------
> When ds is a ClientDataSource40 (i.e. when running with jdk16), recreatedDS is null.
> Note, that this showed up only after converting the test to junit, because the original
test hardcoded the ds to be a ClientDataSource. I confirmed this not to be related to my changes
for DERBY-2296 (which prompted me to convert the test), by backing out my changes to ClientBaseDataSource
and client/am/Connection and rerunning the test (needed some minor adjustments of expected
values table/array).
