Apache Derby's server not listening

ph flag
DBG

I am running into problems with Apache Derby using IntelliJ Ultimate IDE.

Steps I've followed to install the server:

  • Download apache derby from > https://db.apache.org/derby/derby_downloads.html
  • Install, enable ufw > sudo apt install ufw && sudo ufw enable
  • Allow the default Apache's Derby port (1527) > sudo ufw allow 1527
  • test the connection > ping -a -c3 8.8.8.8

As a mate has suggested, the problem occurs because the Apache Derby seems not to be listening.

I wonder how to solve that.

Thanks in advance!!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
