Adobe's LifeCycle Data Services ES offers developers powerful
capabilities. Some of this software’s capabilities, specifically
server push, can be developed with relative ease using a utility class that
has been around in the Flash APIs for a great while, and without having to
pay licensing fees for LifeCycle Data Services ES. The utility class
spotlighted in this article is flash.net.XMLSocket, and it provides all the
client-side plumbing required for implementing server push. In the context
of this article, server push is defined as the ability for a client to
register with a server its interest in remote data events such that when an
event occurs, a notification (and perhaps related data) is pushed from the
server out to the client without the client implement... (more)
EJB. JSP. JMS. JMX. JCA. JTA. JAAS. JAXP. JDBC. JNDI. This is a partial list
of the acronyms you'll find in the 228-page J2EE v1.4 public draft. Of
course, I was able to assemble this list of acronyms before I reached the
bottom of page six.
This new version of J2EE is presented as the Web services version, so to be
fair I should add SOAP, SAAJ, JAX-RPC, and JAXR to this list. In this age... (more)
How can Sybase's EAServer architecture help create a bridge between the
worlds of Java and PowerBuilder to access advanced cryptographic
functionality that isn't natively available in PowerBuilder?
Part 1 of this article ("A Little Security in an Insecure World" [PBDJ, Vol.
9, issue 12]) established a level playing field by introducing you to
terminology that as PB developers we typically... (more)
The number of PowerBuilder and EAServer solutions in production continues to
grow. It would be an understatement to say that there's a large XML movement
underway in the industry. While PowerBuilder 9.0 will include some exciting
XML capabilities, this article focuses on building a solution that provides
XML capabilities for DataWindows today, in PowerBuilder 7 and 8.
We'll describe the d... (more)
In the early days of PowerBuilder, who would have ever envisioned that so
much Web development could be accomplished with our beloved IDE?
Historically, PowerBuilder programmers haven't been exposed to applications
that demand high levels of security, but that's changing - rapidly. PKI,
digital signatures, and other forms of mathematically based cryptography are
now mainstream and being ... (more)
