Thank you for the assistance.
It's not an exception, it's a compile error. I am casting the connection
object to a PGConnection...interesting to note though that the methods
available on the PGConnection object only shows the addDatatype method.
the error: the method getNotifications() is undefined for type PGConnection.
What I see now is PGNotification is not available but PGConnection is...not
sure I saw that earlier. Where is that class? Thought it was part of the
same package.
The code is something I found online:
import java.sql.*;
...
Listener(Connection conn) throws SQLException {
this.conn = conn;
this.pgconn = (org.postgresql.PGConnection)conn;
Statement stmt = conn.createStatement();
stmt.execute("LISTEN mymessage");
stmt.close();
}
public void run() {
while (true) {
try {
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("SELECT 1");
rs.close();
stmt.close();
org.postgresql.PGNotification notifications[] =
pgconn.getNotifications();
if (notifications != null) {
for (int i=0; i<notifications.length; i++) {
System.out.println("Got notification: " +
notifications[i].getName());
}
}
...
