I’ve mentioned that for larger projects/examples on thinkmiddleware.com, Ant would be used. The Java Security Manager article was the first time it was used. Although, the full details of the source code were not included, Ant was used.
Read article: Ant — Build ControlIn the last post, the Java Standard Edition and Java Enterprise Edition security features were introduced. This is the second in a series of articles that introduces each Java security feature in depth. This article introduces the Java Security Manager and the sandbox it creates for a Java…
Read article: The Java Security ManagerWhile researching details for a Java Security Manager article, it became obvious that I didn’t understand the mappings of all the different Java, security-related specifications to the technologies and acronyms I knew. Thus, was the beginning of this article. Below each security-related feature in…
Read article: Java Security — The Low-Level details To J2EE Security–And, BeyondThe original article is located here. In this article, I described what was involved in writing a server program in the C language. The details are not important, but I wanted to compare the details that are exposed in this relatively simple C network programming example with the equivalent Java…
Read article: Java Networking API vs. The C library networking APIThe original article can be found here. Introduction
Read article: Concurrency And Server-Side Networking APIs — Part 4This is part three of an exploration of how concurrency in networking APIs works in Unix-like operating systems and Java technology. This article now looks at the Java equivalents of several C-based server implementations that have been presented. If you haven’t read this series from the beginning,…
Read article: Concurrency And Server-Side Networking APIs — Part 3In the second part of this series we continue to explore how Unix-like operating systems implement the networking API and threading API. In particular, we are supremely interested in how the kernel allows server programs accept incoming connections. Part two explores implementing concurrency in…
Read article: Concurrency And Server-Side Networking APIs — Part 2This article explores how a Sun Hotspot JVM behaves when accepting incoming TCP/IP socket connections. The behavior of native server programs–written in C–are also explored to better understand how concurrency can be achieved. Then, a comparison of how these runtime environments implement…
Read article: Concurrency And Server-Side Networking APIs — Part 1Several terms have been used liberally throughout articles on thinkmiddleware.com. A moment should be taken to formally define them. I am going to attempt to present these concepts in as generic a sense as possible, but the truth of the matter is, every OS has its own threading model and…
Read article: Threads, Threads Everywhere. And, Not a Needle In SightIt happens. End users are complaining about a slow system or a request that never returned. You log into a production middleware server and notice that a java process is consuming an entire CPU or worst every available CPU on the box. It has happened again–a thread(s) has gone into an infinite loop…
