JDBC-ODBC problem with JBuilder

I am trying to get my program to read a list of table names. I use the following code (after establishing the connection successfully) // Get a list of table names for the Icon database and put these names // in an appropriate combo list box. String tableNames[] = new String[1000]; short index = 0; String[] tableTypes = {"TABLE"}; ResultSet rs = meta.getTables(null, null, "%", tableTypes); while (rs.next()) { tableNames[index++] = rs.getString("TABLE_NAME"); } Can anyone suggest why I get a CURSOR NOT OPEN error from the ODBC driver on the call to rs.next()? It doesn't happen when I connect to databases on other platforms using different ODBC drivers - and only happens INTERMITTENTLY on Informix. Many thanks, Pete
