When developing an application in a web server environment, the ease of use and startup time of the application are crucial elements for best performance. Due to this, the Hot Code Replace (HCR) debugging technique was developed to “facilitate experimental development and to foster iterative trial-and-error coding,” effectively improving…

I’m a Spring fan, but I decided not to use Spring in our recent project because I don’t want bulky jar files in our application but I wanted to have spring-like configuration. So, I’ve decided to write my own dependency injection code in less than 50 lines of code!! To simplify dependency injection, I’ve taken out most of the advanced configuration features and…

Are you familiar with common mistakes such as checking equality of two Strings on Java using “==”? Or calling an instance method of a null object? They may look like obvious cases of bugs but many developers are unaware or unconsciously make these kind of codes. Static code analysis tools, such as FindBugs inspects and analyzes Java bytecode and…

Here’s some statistical analysis as to popularity of recent web technologies in Java. By comparing the searches performed between Struts 2, JSF, Spring MVC and JBoss Seam using Google Trends, it appears that Struts 2 is gaining traction among Java developers while JSF started to lose ground since mid-2007. Searches for Spring MVC and JBoss Seam…

After two days of debugging our codes on transaction handling, I’m writing this post to share my experience so others don’t have to undergo the same pain and torture. However, this post assumes that you’ve setup your Spring transactions - either via AOP or annotations. If you haven’t done so, I’ve listed some good references right after the jump.

One common requirement in developing enterprise applications is to ensure audit logs are available for data security and traceability. Who made the changes, when and where. Such requirement is not only dictated by corporate IT policies but is also required by government laws. Considering most enterprise applications have at least 50 domain objects…
