Error opening the OrientDB database

I have a problem with the URL where I am trying to catch my DB. Here is the code:

TransactionalGraph graph = new OrientGraph("/home/danicroque/Escritorio/demoCroque", "admin", "admin");

Here is the error:

I am trying to run this code in Ubuntu with Netbeans. The name of the DB is demoCroque and the URL is /home/Escritorio/demoCroque.

How can I solve this problem?

Solution

  • It looks like your URL is formed incorrectly.

    See here: http://orientdb.com/docs/2.2/Console-Command-Connect.html

    <database-url> Defines the URL of the database you want to connect to.
It uses the format <mode>:<path>

<mode> Defines the mode you want to use in connecting to the database.
It can be PLOCAL or REMOTE.

<path> Defines the path to the database.

    Try something like this as your URL:

    REMOTE:192.168.1.1/demoCroque

    Or

    PLOCAL:../home/Escritorio/demoCroque

    Edit: for the purpose of testing use a full file path until you know it works correctly, for example:

    PLOCAL:C:/projects/myproject/Escritorio/demoCroque
