In the File menu, select New -> Package. Name the new package quickstart, and then click the Finish button.

Figure 2.3. Create quickstart package

In the Package Explorer, right-click on the new quickstart package and select New -> Class. Set the class name to QuickStartObject. This will be our ActiveSpaces® Transactions managed type. Click the Finish button.

Figure 2.4. Create QuickStartObject class

Now edit QuickStartObject.java in the edit pane. We will add an @Managed annotation to the class, and define a package-private String field named message. The class should look like the following:

package quickstart;

import com.kabira.platform.annotation.Managed;

@Managed
public class QuickStartObject 
{
    String message;
}

As a Managed type, any instance of this object we create will be stored in ActiveSpaces® Transactions shared memory.

Now we'll create another public class with a main() method. As before, right-click on the quickstart package and select New -> Class. Set the class name to Main, and let Eclipse generate the method stub for us:

Figure 2.5. Create the Main class

Replace the empty main() method body with some transactional code. We'll create and update an instance of the Managed QuickStartObject class we defined:

package quickstart;

import com.kabira.platform.Transaction;

public class Main 
{
    public static void main(String[] args) 
    {
        new Transaction() 
        {
            @Override
            public void run() throws Rollback
            {
                String message = "Welcome to ActiveSpaces® Transactions
!";
                System.out.println(message);
                
                QuickStartObject quickStartObject = new QuickStartObject();
                quickStartObject.message = message;
            }
        }.execute();
    }
}

Take a moment to check for any source errors identified by Eclipse. Under the File menu, select Save all.
