The first icon is for disconnected database connection object, the second for an established database connection object.
Note that when we have created the testdb database, a Java DB server was automatically started and a connection created. New database connections can be created by right clicking on the Java DB driver and choosing the Connect Using option.
We are going to create an embedded Java DB database connection. Before creating the connection, we need to stop the Java DB server if it is running. Java DB database cannot be booted by a Java DB server and connected to by an embedded driver at the same time. Note that we did not have to start the server explicitly. The server could be started behind the scenes. For example by connecting to the Java DB server connection object or creating a new database. We click on the Java DB node with a right mouse button.
If the Stop Server option is enabled it means that the server is running. We select it to stop the server. Similarly, we create a server connection by choosing a Java DB Server driver. We have a New Connection Wizard dialog. In this dialog, we fill in the database name and user credentials. We have specified the full path to the testdb database.
The Java DB system directory seems not to be taken into account here. After successfully creating the embedded database connection, we see the above icon in the NetBeans Services window. The database connection is created. Improve this question. Vadim Kotov 7, 8 8 gold badges 45 45 silver badges 60 60 bronze badges. Add a comment. Active Oldest Votes. In my Netbeans 8.

Bob Matthews. Optional 'thank-you' note:. Carey Brown. Saloon Keeper. I like You are concatenating protocol with dbname which also contains the protocol. Carey my bad! I believe it's the database server that's responsible for knowing where a particular DB is kept. Ron McLeod. He is using the embedded driver org. EmbeddedDriver , so the path to the DB location needs to be specified. Your database URL looks correct. Is there a derby. It may provide some clues.
Maybe getConnection wasn't happy. Tim Holloway. I couldn't locate a derby. Fortune smiles upon you. I used in-memory derby for a product I used to maintain as the testing database. I think you're running the network server, not the in-memory server. You want the library for the embedded driver and engine.
I am running a standalone java program on a trading platform at Dukascopy no "POM" required I setup the database and its tables from within Netbeans, as I did 5 years ago. Is there something inherently wrong with the way I am setting up the database and tables from within Netbeans? I find it easy to follow and easy to create. From the sound of it, you're using Netbeans as a database administration tool and to run your application as a Netbeans project, not as a stand-alone program.
Nothing wrong with that other than that as long as you only need to run it for yourself and not in an Enterprise environment. But there are a couple of things to be careful about.
The most important thing is that your Netbeans database "workbench" may not be using the same derby driver JAR file that your project is using. Generally you'd have to set the driver jar both as part of the database editor's configuration and in the runtime classpath as separate operations.
There are very good reasons for that, including the fact that the primary purpose of an IDE is to be able to build apps that can run without the IDE.
