I/O error

Hi all,

Someone could explain to me the meaning of this exception:

An I/O error occured while reading from backend - Exception:
java.net.SocketException: Connection reset

java.net.SocketException: Connection reset

at java.net.SocketInputStream.read(SocketInputStream.java:168)

at
java.io.BufferedInputStream.fill(BufferedInputStream.java:183)

at
java.io.BufferedInputStream.read(BufferedInputStream.java:201)

at org.postgresql.PG_Stream.ReceiveChar(Unknown Source)

at org.postgresql.core.QueryExecutor.execute(Unknown Source)

at org.postgresql.Connection.ExecSQL(Unknown Source)

at org.postgresql.jdbc2.Statement.execute(Unknown Source)

at org.postgresql.jdbc2.Statement.executeQuery(Unknown Source)

when I try to invoke DB function to remote DB.

could it be a driver trouble?

Thanks,

Roberto.

The driver is reporting a TCP/IP-level communication error.

The usual cause is a stateful firewall betweeen the JDBC client and the
server. A connection that stays idle for a long time may be considered
dead and dropped by the firewall, and you will see a "connection reset"
error when it is eventually reused.
