ObjectDB+Gradle Template

This is a starter project for working with ObjectDB and Gradle. The code is mainly adapted from the ObjectDB Maven Example to work with Gradle, with some slight improvements.

Connecting to ObjectDB

Connecting to an ObjectDB instance (whether local or remote), will create a database file where all your objects are stored

Local

The following example creates a database file db/points.db where all your persisted objects are stored (relative to the current working directory):

var emf = Persistence.createEntityManagerFactory("objectdb:db/points.odb");

Remote (using ObjectDB server)

The default credentials for an ObjectDB server is admin for both username and password.

var properties = new HashMap<String, String>();
properties.put("javax.persistence.jdbc.user", "admin");
properties.put("javax.persistence.jdbc.password", "admin");
var emf = Persistence.createEntityManagerFactory("objectdb://localhost:6136/points.odb", properties);

Running

To run the application, run

.\gradlew run    # Windows (Powershell)
gradlew run      # Windows (Command Prompt)
./gradlew run    # Linux/Mac

Unfortunately a distributable JAR is not yet supported, as it seems to be a very involved process.

Project Structure

The src directory is where all the application code goes:

src/
├─ main/        # The main application code
│  ├─ java/         # All your Java source files
│  ├─ resources/    # Any non-Java files you might need for the project
├─ test/        # Testing code
│  ├─ java/         # All the Java files used for testing
│  ├─ resources/    # Any non-Java files needed for testing
