-------------------------------------
Sorry, I didn't meant that this is something broken in Teiid, I just submitted an idea
to make things simpler, or more evident, when possible.
I know that a standard jdbc rdbms connection is much simpler to test (it's more or
less always the same method), but that is the point, imho: I can test that kind of
connection easily in many other ways (even connecting directly with squirrel, using the
same jdbc driver for the rdbms).
Other connection types (files/network protocols, specific connectors), which have no
"test" button in Wildfly/Teiid, how can hey be tested? Of course they could be
very different from each other... In the linked thread, I tried to use php or soapui, but
that didn't help either. Both connected, while Teiid didn't.
As Steven said above, at least some better error reporting when connection fails could
help. In my case the remote server response was missing a rfc required field: Teiid was
doing the right thing as for the rfc, but... that was invisible to me, I only got
"server error"on the client, and many strange (to me)bcfx errors in the
server.log.
Probably Ramesh examined the code and spotted there what was happening? I would have tried
to add CXF logging but Ramesh was faster to find the cause of the issue, and made a
patch.
Maybe (eg) in that case Teiid could log a line like "access token received, but the
remote server response is missing the required field token_type, so we can't use that
-. see rfc xxx). That would also help a lot.
Or, at least suggest in the docs how to get more details if connection doesn't seem to
work... that kind of thing.

Key: TEIID-4356
URL: https://issues.jboss.org/browse/TEIID-4356
Project: Teiid
Issue Type: Feature Request
Components: Misc. Connectors
Reporter: Marco Ardito
Assignee: Steven Hawkins
Priority: Minor
Could a sort of "connection test" be implemented to verify if a
"connection definition" specified for a resource adapter (eg: file, google, etc)
is working, and can "connect" to the resource it's supposedly pointing to?
Data sources(jdbc) already have this kind of test, and it is quite useful to test if
there's any error in their connection definition.
With resource adapters, one must define connection definitions, but it is not possible to
test them, independently from later requests/queries (eg: reading data from .csv or .xls
files, or oauth web services): one has to build all the chain and really try to get data
from the source, using the vdb, hoping everything is correctly defined...
Recently I am struggling with a custom rest oauth2 RA, and I need to define
- security domain (with client id/secret, tokens, auth uri)
- RA using that domain
- a connection definition for the RA accessing the remote data source
- a VDB using the connection definition
- a client using the VDB to try get data in sql form
any step could be wrong, but only the last allows to check if the whole chain is working,
or not.
For any error or failure, regular users (like me) can't do anything else than double
check everything... a "test connection" button, for the connection definition,
would do wonders to simplify setup debug...
