A fair number of validation rules are of the toggle variety: required fields, fields that must be a certain length (no longer than, no shorter than), fields that must be greater than or less than other fields, and so forth. The common theme is that validation rules, when broken, immediately make the object invalid. In short, an object is valid if no rules are broken but is invalid if any rules are broken. Rather than trying to implement a custom scheme in each business object in order to keep track of which rules are broken and whether the object is or isn t valid at any given point, this behavior can be abstracted. Obviously, the rules themselves are often coded into an application, but the tracking of which rules are broken and whether the object is valid can be handled by the framework.

Allowing a readonly field to be modified during object construction is a useful feature. It means that you can create a per-instance constant value, which depends on the way in which your object was constructed. In Listing 7-15, the instances of Product each had a constant field with a different constant value. Once constructed, the object cannot change the value assigned this field, which can be useful for avoiding inadvertent modifications.

As previously mentioned, network home directories are both a blessing and a curse On one hand, they provide a very valuable service to any environment where users do not have pre-assigned computers and may move about from node to node at will However, if you take into account all of the various activities that can occur inside a user s home directory, it quickly becomes apparent that the overhead necessary for deploying the storage infrastructure to handle the burden imposed by such activities is not insignificant An IMAP account of even a moderately sized user mailbox can easily contain tens of thousands of files A user logging into a computer results in a flurry of activity as numerous components load their support files There is the occasional application in which file system needs are particularly burdensome on a file server.

Figure 1-8. A highly available MSMQ architecture Once the message has been placed in the outgoing queue, a listener picks it up and processes it from there. In this architecture, the queue listener extracts the body of the message and posts it to SQLXML as a SOAP request for a Web Service. This facility is built into SQLXML. Any stored procedure can easily be exposed with SQLXML listening for incoming SOAP requests and automatically mapping them to the database stored procedure. After the database work is complete, a response message may be prepared, depending on whether the request was synchronous or not. For asynchronous requests, a fire and forget model is used, and so no response message is necessary. One major benefit of this architecture is that other non-web applications could leverage the same MSMQ infrastructure (i.e., Windows Services, BizTalk Orchestration). The initiating application need only know how to generate the transaction XML, and then throw it in the queue. The listener takes over from there.

First, we instantiate a new transient object user as usual Of course, we might also instantiate it after opening a Session; they aren t related yet We open a new Session using the SessionFactory referred to by sessions, and then we start a new database transaction A call to save() makes the transient instance of User persistent It s now associated with the current Session However, no SQL INSERT has yet been executed The Hibernate Session never executes any SQL statement until absolutely necessary The changes made to persistent objects have to be synchronized with the database at some point This happens when we commit() the Hibernate Transaction In this case, Hibernate obtains a JDBC connection and issues a single SQL INSERT statement Finally, the Session is closed and the JDBC connection is released.
