"Starting Derby as an embedded database

To start Derby, you start the Derby JDBC driver. Starting the Derby driver starts up the

complete Derby system within the current JVM.

For example, when using the JBDC driver manager directly within Java code, you

typically start a JDBC driver in one of these ways:

? Specify the jdbc.drivers system property, which allows users to customize the JDBC

drivers used by their applications. For example:

java -Djdbc.drivers=org.apache.derby.jdbc.EmbeddedDriver

applicationClass

? Load the class directly from Java code using the static method Class.forName. For

example:

Class.forName(“org.apache.derby.jdbc.EmbeddedDriver”);

? If your application runs on JDK 1.6 or higher, then you do not need to explicitlty load

the EmbeddedDriver. In that environment, the driver loads automatically and the

engine starts when your application requests its first Connection.

For more details, see “java.sql.Driver interface” in the Java DB Reference Manual.

Once the Derby JDBC driver class has been loaded, you can connect to any Derby

database by passing the embedded connection URL with the appropriate attributes to the

DriverManager.getConnection method.

For example:

Connection conn = DriverManager.getConnection(“jdbc:derby:sample”);

try{

Connection con = DriverManager.getConnection(“jdbc:derby://localhost:1527/CRHDatabase”, “crh”, “crh”);

launch(CRHDatabaseApp.class, args);

}catch (Exception ex){

System.out.println("Erro na execução: " + ex.getMessage());

}

public class start {

    public static void main(String[] args) {
        try {
            //Executa comando do windows ou linux no rt.exec("comandos");
            Runtime rt = Runtime.getRuntime();
            Process proc = rt.exec("cmd /c start derby\\bin\\startNetworkServer.bat");//Envés de "derby\\bin\\startNetworkServer.bat" pode ser C:\\Tao\\Oquefor
            //No meu caso descompactei na pasta do meu programa e do start.jar e chamei de derby a pasta do server.
            proc = rt.exec("cmd.exe /c start java -jar SeuPrograma.jar");//Envés de "SeuPrograma.jar" pode ser C:\\Oquefor\\SeuPrograma.jar
           //Process proc = rt.exec("cmd /c start derby\\bin\\stopNetworkServer.bat"); para parar o servidor.
        } catch (Throwable t) {
            t.printStackTrace();
        }
    }
}
