NAME YEARSAL -------------------------------- -------AB CLARK 29400 CC KING 60000 TJA MILLER 15600 Now take a look at the rather odd query shown in Listing 4-7. Listing 4-7. Selecting an Expression with Literals select 3 + 4 from departments; 3+4 -------7 7 7 7 The query result might look strange at first; however, it makes sense when you think about it. The outcome of the expression 3+4 is calculated for each row of the DEPARTMENTS table. This is done four times, because there are four departments and we did not specify a WHERE clause. Because the expression 3+4 does not contain any variables, the result (7) is obviously the same for every department row.

Keep in mind that the discussion so far has been about the bare minimum functionality necessary for getting a service up and running I haven't even touched on the fundamental requirement of ensuring that your general algorithms and implementation work for the oneof-a-kind pieces of your service The easiest and best way to debug services without becoming completely overwhelmed is to approach the debugging in stages Two main stages are involved when you're debugging services: Debugging the core code Debugging the basic service In the following sections, I'll describe what you need to do in each stage to make sure that you stand the best chance of debugging your service with a minimal amount of hassle Debugging the Core Code Before you even consider running your application as a service, you need to run and test your application as a standard user-mode executable until you've debugged all your core code.

3 Define an event In this example, MailMsg is the name of the event This event is of the MailMsgEventHandler type, meaning that all receivers of the event notification must supply a callback method whose prototype matches that of the MailMsgEventHandler delegate 4 Define a protected, virtual method responsible for notifying registered objects of the event The OnMailMsg method is called when a new e mail message arrives This method receives an initialized MailMsgEventArgs object containing additional information about the event This method should first check to see whether any objects have registered interest in the event, and if they have, fire the event A type that uses MailManager as a base type is free to override the OnMailMsg method This capability gives the derived type control over the firing of the event The derived type can handle the new e mail message in any way it sees fit.

You ve probably noticed that the Bid entity doesn t have a method to save itself into the database. The JPA EntityManager performs this bit of heavy lifting by reading ORM configuration and providing entity persistence services through an API-based interface.

Once you've done that, you can start working on the issues specific to services When debugging your core code, you should debug everything on the same machine, running under your developer account; that is, your service core code as well as any client code should be on the same machine With this approach, you won't have to worry about any security or network issues Once you debug your logic, you can move on to the joy of other problems you'll encounter with services, such as security and service initialization orders..
