Tools needed


Java 8 (1.8) needed at least.


Use the gradle wrapper (type gradlew or ./gradlew instead of gradle).

Otherwise download and install gradle from Until further notice you can use the newest version. Orcas rquires at least gradle 3.3.

Orcale jdbc driver

You need to provide the oracle jdbc driver. please make sure you find a way that works with the oracle license terms.

  • add to local maven-repository (yes maven-repository although this is the gradle guide):

    Execute the following command, make sure you replace the location of the ojdbc6.jar. mvn install:install-file "-Dfile=C:\oracle\product\11.1.0\client_32\jdbc\lib\ojdbc6.jar" -DartifactId=ojdbc6 -Dversion= -Dpackaging=jar

  • direct path in build.gradle:

    add direct classpath to the dependencies-section of your build.gradle (see next section on wherer to find the build.gradle for the orderentry example): classpath files('C:\oracle\product\11.1.0\client_32\jdbc\lib\ojdbc6.jar')

  • form

    The driver is also accessible via, note that this requires a login-configuration

The orderentry example

Obtain orcas

Download and extract orcas.

Configure Orderentry example

Edit examples\gradle\build.gradle and setup your database connection (and additionally the jdbc-driver setup if needed).

The default database user is created like this:

create user orcas_orderentry identified by orcas_orderentry;
grant connect to orcas_orderentry;
grant resource to orcas_orderentry;
grant create sequence to orcas_orderentry;
grant create view to orcas_orderentry;

Start orcas

Exceute gradle databaseDeployment at a command line located at examples\gradle.

For gradle wrapper use gradlew databaseDeployment or ./gradlew databaseDeployment instead.
