When we encounter a java.lang.OutOfMemoryError, we often find that Java heap dumps, along with other artifacts, are generated by the Java Virtual Machine. If you feel like jumping right into a Java heap dump when you get a java.lang.OutOfMemoryError, don’t worry, it’s a normal thought....
This paper will attempt to discuss the usage scenario and demonstrate the use of WXS as a separate in memory data grid to store http sessions. This paper will discuss history and existing technology and introduces WXS as a technology that differentiates itself, by addressing existing s...

 

Abstract

There are many different types of command line options that programs need to recognize. Many languages (e.g.: bash and perl) has built-in processing of command line options; Java does not. The Java Command Line Options (JCLO) package performs this task for a va...

One of the main issues that PowerBuilder and PowerBuilder developers have been facing for the last few years is the lack of mind share for the product. All that seems to have changed with Sybase’s announcement of the beta of PowerBuilder 12.0. Articles on the release appeared in a larg...
In today’s technology-dependent enterprise environment, the efficiency of most business processes depends directly on the effective performance of the IT infrastructure. Almost every single activity - from servicing a customer to shipping purchased products - is dependent upon one or m...
With its ability to provide users dynamically scalable, shared resources over the Internet and avoid large upfront fixed costs, cloud computing promises to change the future of computing. However, storing a lot of data creates a situation similar to storing a lot of money, attracting m...
Not long ago I worked on a team charged with building up a Java-based REST infrastructure. Our goals were to first support what was then an emerging specification for Java-based RESTful services called JAX-RS. Beyond that, we had thoughts of building an entire framework, both server an...
