Incorrectly specifying database name with JDBC protocol causes unhelpful error
message in client data sources
-------------------------------------------------------------------------------------------------------------
Key: DERBY-3407
URL: https://issues.apache.org/jira/browse/DERBY-3407
Project: Derby
Issue Type: Bug
Components: JDBC, Network Client
Affects Versions: 10.4.0.0
Reporter: Kristian Waagan
Priority: Minor
If the database name is specified with the JDBC protocol, the user is presented
with very unhelpful error messages.
On the embedded side, a meaningful error message is produced and presented to
the user.
Even though specifying the JDBC protocol can be classified as a user error, it
would be good if Derby gave a meaningful hint for what is wrong.
For instance:
cp.setDatabaseName("jdbc:derby://localhost/kwTestDB");
cp.get(Pooled|XA)Connection();
