Harness RAD 7.5 power to persist data in DB2 for i. By Jarek Miszczyk I believe that EJB 3 and its core element, Java Persistence API (JPA), have finally fixed what had been broken in the J2EE data persistency specification. The inherent complexity of previous EJB versions significantly reduced the adoption of this technology. With the introduction of EJB 3, the sanity returned into the world of enterprise Java development. EJB3 is a new programming paradigm that rests on Plain Old Java Objects (POJOs), Java annotations, and the dependency injection design pattern. With EJB3, you can create well-performing, high-quality applications faster and at a lower cost. |

Whether it's verifying the integrity of a message's source, a software license file, or a download, employing digital signatures is imperative. By Joe Cropper So just what is a digital signature anyway? A digital signature is the digital era's equivalent of yesterday's hand-written signature. That is, each time we sign that receipt after using our debit or credit card, we are effectively telling our financial institution that we agreed to pay a given price for a given item. In the event that an alleged fraudulent charge is made, authorities can perform signature comparisons to help determine the validity of the claim. Digital signatures work in a similar fashion for electronic messages. |

If you've been putting off learning Java, you have no excuse anymore! By Joe Pluta Java for RPG Programmers has been popular for nearly a decade. This unique book manages to bridge the gap between the procedural nature of RPG and the sometimes mysterious world of Java and object-oriented programming (OOP). This Third Edition is a worthy entry in the book's history. The problem for RPG programmers is that most Java books don't differentiate between application programming and system programming. Java has a dual nature: Java experts use the advanced features of the language to build system-level routines, and application programmers use those routines to build applications. Most RPG programmers need the latter explained in familiar terms. |
