I was trying out HSQLDB to run SQL scripts with ANT last night when I encountered java.lang.UnsupportedClassVersionError. Never encountered this in 3 years of coding. Recently, I tried to play safe and installed several JDK (and JRE) versions, and so it happened. Quick diagnostics: Run java -version...

I was asked to solve a problem of parsing a float value in dutch format ( 9,6 instead of 9.6). The former would always parse as a whole number, 96 instead of 9.6 ). I read on the documentation from sun, http://java.sun.com/j2se/1.4.2/docs/api/java/text/DecimalFormatSymbols.html and I saw that a method...

Configuration is an essential part of every software development project. Among other things, we store sensitive information such as database, ftp and other credentials in these configuration files. This may not be an issue for a small company. But if you're working for a large bank, this becomes...

I was encountering the error below everytime I tried to invoke a WS client in RAD7. I was calling the WS through a console application using a generated client stub. Deployment error: java.io.IOException: FATAL ERRORS encountered by WSDL2Java tool. at com.ibm.ws.webservices.wsdl.Parser.generate(Unknown...

I'm very sensitive on how I know my variables when I program and the most I'm very careful with is naming boolean variables. So I was trying to create a new variable inside of Eclipse and I'm not used to naming my boolean vars like isNew, isAllowed or isValid but instead I know them new,...

In my office, TDD is a new methodology that we've just began adopting. My senior wrote a TestCase class before he left the company. Thanks to him, I got some sample codes to study. After baby sitting, I decided to open my computer and fire up netbeans. We're using RAD at my work btw, I could...

Well... It was one hell of a week for me and I needed something to remind me how fun programming is. Or used to be hehehe. This was supposed to be an entry to Keith's contest, I unfortunately fell ill a few days before the deadline and wasn't able to continue with it. I had the change to continue...

Because of the inspiration from what Chris Williams started I have decided to start Ten Questions - Filipino Developers Edition . Basically, the idea is to interview well-known Filipino developers and ask them 10 questions that would shed light on their persona and their geekiness! On this first go around...

Just a quick post from me here. I couldn't find any resources on the internet, I couldn't remember how I found this solution. Here's the scenerio. When you try to parse and Excel sheet using JXLS, unless your Excel sheet column is formatted in General, you wouldn't be able to get the...

Note: In reading this post, please disregard for a moment the difference between an exception and an error. I mainly used the word error for convenience. Thank you. Yesterday, I was given a tip by my team lead which I found nice and quite elegant to do so. Before, when I'm trying to catch an error...

While reading Bruce Eckel's article, Java: Evolutionary Dead End, he mentioned of another programming language which is somehow based on Java(and runs on the same VM) but has the feel and construct of a Scripting language(e.g. Ruby). I got interested and quickly searched for any related article and...

Note: I've done the following using Rad7 but should also be applicable to Eclipse(since RAD7 is basically made on top of Eclipse). When you have total control of you web container/app server, deploying jar files is as easy as dropping the folder in your common lib folder. If you don't package...

I'm a bit irritated about Session Beans because I have to implement the Serializable interface for every object that I pass to a Remote method. Of course, it totally makes sense to do that when you're making remote invocation but I'm thinking if there's any way around this problem aside...

I'm still not doing much here in my new job. There's still a lot of things to be set up. I finally got to meet with our very own Nards (N.Ocampo). Aside from that, I've been reading on Java Enterprise Design Patterns for the past one week They are: Service Locator - Abstracts JNDI lookup...
