Rich- I cross checked by using the C library and got a similar error (though not identical): java.sql.SQLException: JZ006: Caught IOException: java.io.IOException: JZ0PA: The query has been cancelled and the response discarded. The cancel was probably issued by another statement on the connection."^;};Error { code = 0; message = "java.sql.SQLException: JZ0C0: Connection is already closed.";}; However, if I stick the .ascii url in a web browser it appears to work ok; at least, no SQL message is shown. I have not looked closely at the output to see if the returned result is correct or not. My current speculation is that it is a server-side error and that code to generate the .ascii output just ignores any errors. =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: SCX-738847 Department: Support netCDF Java Priority: Normal Status: Closed
