[dtp-connect-dev] Firebird support in DTP

[Roman Rokytskyy <rrokytskyy@xxxxxxxxxxx>]

Hello,

Let me first introduce myself. I am currently main developer of the 
Firebird's JDBC driver (Jaybird) as well as one of the admins of the 
Firebird project.

Right now I am trying to add support for Firebird RDBMS to DTP and 
experience some problem. The main specifics of the Firebird is that is 
does not support schemas. I have created appropriate extensions of the 
org.eclipse.datatools.connectivity.driverExtension extension point and 
it works - DTP is able to load and show the database objects.

The next problem are the Data->Sample Contents, Data->Edit and similar 
functionality. I have discovered that in many places DTP generates the 
qualified name of the table by using schemaName + "." + tableName 
ignoring the "Schema supported" setting in the corresponding XMI-file.

At this point I have started checking whether I can override the 
functionality by creating my own plugin that would reuse existing DTP 
code and override some methods (e.g. TableDataEditor.initDbOutputItem()).

I have subclassed the ProfileActionsActionProvider and the 
DataSourceExplorerView classes and configured the appropriate extension 
points in the plugin. However, I experience one problem - my custom view 
contains the registered profile nodes, but when I connect to the 
database, the tree content is updated in the original DSE view, not in 
my customized one. I have spent some time to solve the issue, but with 
no success.

Now it is time to ask questions :)

a) is there any way to tell DTP not to use schema when computing 
qualified names without directly modifying the DTP sources?

b) assuming that overriding those methods is the only possibility to 
solve the issue, where can I get help about subclassing/customizing the 
DSE and related classes?

Thanks a lot in advance!
