Introduction XML has become the common format for passing data between components residing on different platforms. With the move to XML-based services, developers often find themselves converting various data structures to and from XML. Arguably, the most prevalent form of persisting data is in relational databases. How does one go about converting relational data structures into XML? In this article, we'll do just that and build a utility to expose relational data as XML documents.

In This Chapter Using JDBC and Data Sources Direct JDBC Database Access Tomcat Data Sources Data Access Objects (DAOs) Security Considerations Most Web applications need to store information on a temporary or permanent basis. The most common repository for data storage is the ubiquitous relational database. In this chapter you will be using databases from within Tomcat Web applications using both direct JDBC access and the preferred approach of JNDI data sources.

There's been a lot of hype lately about Java Data Objects (JDO). It appears to be the new silver bullet that will alleviate all of our coding drudgery. JDO threatens the livelihood of products such as object/relational mapping utilities that map Java objects to relational data. Because of this, and for other reasons, JDO has received more than its fair share of bad press.

Java developers use serialization, JDBC, or EJB Container Managed Persistence (CMP) for the persistence of the data in their programs, but each of these commonly used persistence mechanisms has some drawbacks (see sidebar Limitations of Current Persistence Mechanisms ). Now, however, the Java Data Objects (JDO) API defined in the Java Community Process (JCP) provides transparent persistence of Java object models in transactional datastores.

This Article uses this code as an example of how to use the JDBC to implement a workaround for a scrolling cursor. It illustrates a number of important techniques, such as how to handle connections, rows, and columns. Very simple example of implementing something that acts like a scrolling cursor in JDBC. Don't use this as an example of good program structure, rather use it as an example for how to get the job done.

Finding the best approach when accessing a database from Java can be a daunting task. The most common solution is to program directly to the JDBC (Java Database Connectivity) APIs. The result is hard-to-read source files, bloated with complex code that has nothing to do with business logic. To make matters worse, JDBC does nothing to address the natural differences that usually exist between a system's object model and its relational data model.

In a past article on XML Databinding , I showed how you could work with Java objects and have them persist as XML files. In this article, I'll discuss Sun's Java Data Objects (JDO) standard. JDO allows you to persist Java objects, supporting transactions and multiple users. It differs from JDBC in that you don't have to think about SQL and all that database stuff. It differs from serialization as it allows multiple users and transactions.
