This means the application must be able to recognize messages arriving out of order and store them somewhere until the missing messages arrive greatly increasing the complexity of the application Even if the messages are delivered in order, if your application is multithreaded for efficiency, the messages still might be processed out of order For example, if thread one receives the order header and starts processing it and then thread two starts processing the first order line, it s very possible that the order line will be processed before the order header is completely processed This chain of events could occur because the order header is generally more complex than the order line and thereby requiring more processing, so inserting the order line into the database will fail because the order header isn t there yet .

The application can try the order line again until it works, but this is inefficient and adds to the complexity of the application If all the messages are in a Service Broker conversation, they will be received and processed in the order in which they were sent so that the application doesn t have to deal with the complexities of processing messages out of order ..

Asynchronous delivery of messages effectively decouples the endpoints of a Service Broker conversation from each other . The application at one endpoint of a conversation sends a message and then goes on to process more work without knowing when or where the message will be processed . It s entirely possible that the sending application and the receiving application never run concurrently . For example, an inventory application might send out manufacturing orders as shortages develop during the day, and the manufacturing

Testing EJB components Testing EJB components is the most difficult part of J2EE testing. Testing whether a behavior is executing properly is relatively simple, but determining the root cause of any errors often requires some detective work. In general, testing your EJB components requires a two-phase approach. The first occurs during development, when detailed logging is built into the EJB methods themselves. Note that, if you are using JDK version prior to 1.4, this logging capability should be encapsulated into its own subsystem (see the Fa ade software pattern) so that your components don t become dependent on your vendor s proprietary logging mechanisms. This is depicted in figure 1.8.

orders might be read by a planning application that runs at night Even if the sender and receiver are running concurrently, asynchronous message delivery means that the sending application doesn t have to wait around for the receiving application to finish processing the message It can continue with other work and rely on Service Broker to reliably deliver the message to the receiver for the receiver to process when it has time available Asynchronous messaging means you can link fast systems and slow systems into a single application without worrying about the slow systems holding back the fast systems For example, your new order-entry system can send shipping instructions to your clunky old shipping system without the shipping system slowing down order entry Virtually all big, scalable, high-performance applications make asynchronous calls to slower parts of the system .

Click Start, click Control Panel, and then click Network and Internet Connections. In the Network and Internet Connections window, click Create a connection to the network at your workplace. On the Network Connection page, select the Virtual Private Network connection option, and then click Next. On the Connection Name page in the Company box, type the name of your company, and then click Next. On the Public Network page, select the Do not dial the initial connection option, and then click Next. On the VPN Server Selection page, type the host name or IP address for your company s remote access server, and then click Next. If you have a smart card, on the Smart Cards page, make sure that the Do not use my smart card option is selected, and then click Next. On the Connection Availability page, make sure that the My use only option is selected, and then click Next. On the Completing the New Connection Wizard page, click Finish.

For example, the operating system performs disk I/O asynchronously, and the Web server makes asynchronous network calls Another example is SQL Server, which performs many asynchronous operations internally With Service Broker, asynchronous processing is now available to database application writers This means, for example, that if you want to write a trigger that does a significant amount of work without slowing down updates to the table, you can have the trigger send a Service Broker message to another application that does the work You can also have one stored procedure call several other stored procedures in parallel by using asynchronous Service Broker messages to start the other stored procedures You will see an example of this later in the chapter Now that you ve seen what a conversation is and what it does, I ll spend the rest of this section talking about how Service Broker implements conversations .
