FEATURED TECHNICAL ARTICLES
Java Data Objects
By Craig Russell - Sun Microsystems Inc.
JDO (Java Data Objects) is a specification for transparent persistence being developed as JSR-000012 in the Java Community Process. Transparent persistence allows developers to store their Java objects in transactional data stores "transparently", meaning that they do not need to explicitly manage the field-by-field storage and retrieval to and from the data store.

Why Prepared Statements are important and how to use them "properly"
By Billy Newport - EJB Consultant
Processing statements can be an expensive operation but databases are now written in such a way so that this overhead is minimized. However, these optimizations need assistance from the application developers if we are to capitalize on them. The correct use of PreparedStatements can significantly help a database perform these optimizations.

ENTERPRISE JAVA EDUCATION STRATEGIES
What makes Java programmers more productive and write code with fewer bugs?
Expert programmers say that experience makes the difference between struggle and ease in building scalable and bullet-proof e-business and Web server Java apps. But, experience takes many months (and mistakes) to attain. That's why the best training strategy is to get Java instruction with architects who have deep development experience, UML and server-side Java skills.
Take any Java training from The Middleware Company before September 30. Game Boy Advance is yours with our compliments. Experience the difference.

SHAPE THE NEXT SET OF DEFINITIVE J2EE BOOKS
TheServerSide.com is hosting two new J2EE book projects: Mastering EJB II, and EJB Design Patterns. Chapters from these two new books will be posted to TSS as they are written for public feedback. For the first time ever you will be able to directly participate in the writing of these two influential books and personally influence thousands of developers who will learn from them.
Latest Public Review Postings:
Mastering Enterprise Java Beans II
EJB QL
1st public review posting, By Ed Roman
EJB-QL is a standard and portable language for expressing container-managed persistent entity bean query operations. These entity bean query operations can include finder methods (used by external entity bean clients), as well as select methods (used internally by the entity bean itself). EJB-QL is not necessary for bean-managed persistence because the bean provider writes the database access code, which is integrated into the entity bean class itself ........

EJB Transactions
1st public review posting, By Ed RomanTransactions, when used properly, can make your mission-critical operations run predictably in an enterprise environment. Transactions are an advanced programming paradigm that allows you to write robust code. Transactions are also very useful constructs to use when performing persistent operations, such as updates to a database ........
Read/Review rest of the chapter
CMP Entity Beans
1st public review posting, By Ed RomanWith container-managed persistence, you don't implement any persistence logic (such as JDBC or SQL/J) in the entity bean itself-rather, the EJB container performs storage operations for you. As you will see, this greatly simplifies bean development ........

EJB Design Patterns
Dual Persistent Entity Bean
1st public review posting, By Floyd MarinescuHow can an entity bean be designed to support either CMP or BMP at deploy-time?
Write entity beans that support both CMP and BMP by separating business logic into a CMP compliant superclass and BMP persistence logic into a subclass. Deployment descriptor settings can be used to select between the two at deployment time ........

NEW J2EE PATTERNS
Safe bulk updates for EJBs
By Roman Stepanenko
Sometimes you need to update 10 000 records. Using EJBs would be overkill. If you use direct JDBC calls how do you tell EJBs in cache that they have outdated data?

KEY J2EE INDUSTRY HEADLINES
BEA takes Oracle Java Performance Challenge and Comes Up Short?
Oracle has posted its response to BEA's recent claims at being 54% faster than Oracle. In a rebuttal entitled "BEA Takes the Oracle Java Performance Challenge...and Comes Up Short", Oracle suggests that BEA cheated by not running the same benchmark as Oracle, and generally spreading FUD.

IDC study shows IBM gaining on BEA
IBM last year continued closing in on BEA's lead in the sizzling application server market, according to a study released Monday. In 2000, BEA captured 18 percent of the market in terms of revenue, or $394 million, while IBM was second with 15 percent, or $337 million. Note that these numbers are in terms of revenue, not # of servers sold.
