    Zenso,

    Sorry that you are seeing this issue.

    The “Network Adapter could not establish the connection” usually happens if the Database is either not listening on the listener port or there might be some other network related issue.

    1. Please ensure you are using correct host name or IP address,url, driver jar, port and the database listener is up and running.

    2. Check with ping using the IP address or host name. Also try telnet to the IP on the port.example : telnet 1.2.3.4 1521.

    3. Please check if you can access and browse the database from outside MyEclipse.

    4. Did you try configuring and connecting to the database from within MyEclipse?
    Here are the instructions to configure the database in MyEclipse : https://www.genuitec.com/products/myeclipse/learning-center/db/connecting-database-myeclipse/

    5. Are both the Tomcat server and database in the same machine on which MyEclipse is running?

    If you are still seeing issues, please send us the full .log file located at workspace dir/.metadata/.log for further investigation along with the database version and details and MyEclipse version details from Help > About MyEclipse section.
