Derby Pool ping fails with java.net.ConnectException in Glassfish

Question

I`m just installed a Glassfish 4.1 on Ubuntu 14.04 and trying to ping DerbyPool but it fails with java.net.ConnectException.

Ping Connection Pool failed for DerbyPool. Connection could not be allocated because: java.net.ConnectException : Error connecting to server localhost on port 1527 with message Connection refused. Please check the server.log for more details.

server.log:

The same problem is occurring on another computer with Glassfish 4.1 and Ubuntu 14.04 installed on it.

Answer 1

I guess you didn't start the Derby server.

To start it, go to the command line and navigate to a folder where you can run asadmin (probably something like /glassfish/bin) and run the following:

asadmin start-database

Then try pinging again.
