Configuration using the Java API

The Java API is most straight forward way to configure fractions in WildFly Swarm. A typical example looks like this:

new DatasourcesFraction()
  .jdbcDriver("h2", (d) -> {
      d.driverClassName("org.h2.Driver");
      d.xaDatasourceClass("org.h2.jdbcx.JdbcDataSource");
      d.driverModuleName("com.h2database.h2");
  })
  .dataSource("ExampleDS", (ds) -> {
      ds.driverName("h2");
      ds.connectionUrl("jdbc:h2:mem:test;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE");
      ds.userName("sa");
      ds.password("sa");
  });
Note
 The complete Javadocs for the config API are available here

In this example we configure the datasource fraction with an additional datasource and a corresponding JDBC driver.

All of the fractions that represent WildFly subsystems can be configured this way. The configuration model is an equivalent to the WildFly XML schema. In fact it is actually generated from it.
