Hi Justin,

Thank you so much for your explanation. I definitely have not thought
of that and will double check with Ingres but I believe Ingres is not
a case-sensitive database. I also have not implemented IngresDialect
properly such that it had been returning false for all calls to
includeTable() but I fixed that, I realized that many things could be
wrong but the error message might still be the same.
I've done some more debugging and moved on from the original problem
to a clearer stage though where in JDBCDataStore.createTypeNames(),
metaData.getTables() did NOT throw an exception but an EMPTY ResultSet
was returned.
I am not yet sure if this is an Ingres problem or my own fault
somewhere but will continue to investigate.
One thing I assumed is normal though is the fact that
ContentDataStore.entry() always does not have that line in its list of
entries the first time its being asked about, hence a call into
JDBCDataStore.createTypeNames() is always necessary.
Let me know if this is not a valid assumption.

Thank you again,
L I M
