Select the application server and Java EE version. This must be the same for all projects in the end-to-end application. The IDE creates an EJB module project that looks like this in the Projects window.

Name the session bean Flower, together with flower.album as the package name. Make sure to select Stateless and Remote. The wizard now appears as follows.

Click Finish.

The IDE adds a session bean to the Source Packages node, together with a remote interface, as shown here. In the Enterprise Beans node, a new node is added for your new FlowerBean.

Type the following values in the Business Method dialog:

Click Add. In Name, type name. Leave the other values unchanged. You now see the following.

Click the Exceptions tab. Click Add. The Find Type dialog opens. Type IO and select the IOException (java.io).

Click OK. You return to the Business Method dialog, which shows the IOException.

Click OK. You now have the basis of a method in your bean class, and a method declaration in the remote interface class.

As before, add IOException to the Exceptions tab. Click through the dialogs and the IDE creates the method.

@Remote
public interface FlowerRemote {

    byte[] getFlower(String name) throws IOException;

    List<byte[]> allFlowers() throws IOException;

}

Look in the bean class and note that stubs have been created for the declared methods.

@Stateless
public class FlowerBean implements FlowerRemote {

    public byte[] getFlower(String name) throws IOException {
        return null;
    }

    public List<byte[]> allFlowers() throws IOException {
        return null;
    }

}

Alternatively, instead of using the Business Method dialog you can manually add code to the bean class and to the remote interface class. However, if you use the Business Method dialog, the IDE adds code to both the bean class and the remote interface class, simultaneously.

Fix imports in the bean and remote interface classes. In each class, place the cursor anywhere in the code, right-click to open the context menu, and select Fix Imports. A dialog box opens showing all necessary imports. Press OK and NetBeans generates the import statements. Alternatively, press Ctrl-Shift-I in each class to open the import dialog box.

The Projects window now shows two new nodes in the Enterprise Beans node, for your new methods, as shown here.

@Stateless
public class FlowerBean implements FlowerRemote {

    private static final String[] FLOWERS = {"aster", "honeysuckle", "rose", "sunflower"};

    public byte[] getFlower(String name) throws IOException {
        URL resource = this.getClass().getResource("/flower/album/resources/"+name+".jpg");
        return getBytes(resource);
    }

    public List<byte[]> allFlowers() throws IOException {
        List<byte[]> flowers = new ArrayList<byte[]>();
        for (String flower:FLOWERS) {
            URL resource = this.getClass().getResource("/flower/album/resources/"+flower+".jpg");
            flowers.add(getBytes(resource));
        }
        return flowers;
    }

    private byte[] getBytes(URL resource) throws IOException {
        InputStream in = resource.openStream();
        ByteArrayOutputStream bos = new ByteArrayOutputStream();
        byte[] buf = new byte[1024];
        for(int read; (read = in.read(buf)) != -1;) {
            bos.write(buf, 0, read);
        }
        return bos.toByteArray();
    }

}

In the Projects view, the images should appear as shown here:

In your code, notice that the methods getFlower and allFlowers both make use of the images in this package.
