Thanks for responding.
The code is as follows where conn is a Connection 
returned from a call to getConnection() on a Datasource from a remote server to my client application using JNDI lookup:

DatabaseMetaData dbMeta = conn.getMetaData();
try {
	tableRes = dbMeta.getTables(null, null, null, types);				
} catch (Exception e) {

The types variable is an array of strings with values TABLE, VIEW, SYNONYM.

As you can see I do not do any casting.  It is the
getTables(...) method that throws the exception.

If you would like I can expose the datasource file here.

It appears to me there is a problem with the proxy used to wrap the DatabaseMetaData and it is a problem when the datasource is to an Oracle database using the thin client driver.
