Programming: Java Servlet Development for Apache Tomcat with Eclipse

I was starting a not-so-small Tomcat servlet development project -- to modify and extend the Blojsom blogging server for my thesis work. I was suggested that Borland JBuilder is a better tool for servlet development. I liked JBuilder when I hadn't known Eclipse. But now that I'm so used to using Eclipse, I don't want to go back.

I was misled that I need a "Tomcat plug-in" for Eclipse to develop servlets. Spent 5-6 hours trying to get the seems-popular Sysdeo Eclipse Tomcat Launcher plugin V3.2 Beta 2 to work the way JBuiilder servlet development tool worked for me. It just didn't work the way I like.

Finally I found a discussion thread on an Eclipse site that refers to the WTP Tutorials – Building and Running a Web Application article by Naci Dai which showed me how to make Eclipse work the way I like:

According to Dai, all I have to do are:

1. Get the Eclipse Web Tools Platform (WTP) from eclipse.org (which I already have)

2. Start the WTP and go to the menu Windows -> Preferences -> Server -> Installed Runtimes. Then add an Apache Tomcat to the runtimes list.

3. To create a servlet project, use the menu File -> New Project -> Web -> Dynamic Web Project.

4. Now we can use the menu File -> New -> Class to create subclasses of javax.servlet.http.HttpServlet and start developing the servlets.

5. Important: Before we can launch the servlet we have to configure the Web Module Deployment Descriptor which is the web.xml in the WEB-INF folder.

6. To launch the servlet, click at the project name in the Project Explorer and use the menu Run -> Run As -> Run on Server.

A Thought on a Reasoner-enabled Version of Del.icio.us (and perhaps Technorati)

I have been adding more bookmarks to my del.icio.us account and have begun tagging them with RDF-like object/datatype properties. Adding more and more object/datatype properties to the bookmark, a provoking thought popped up: It would be nice if tagging can be assisted by ontologies and a logic reasoner. Look at del.icio.us/thitiv . The _hasAffilication:CUPhoto property should be a subproperty of _hasAffiliation:Chula (provided that CUPhoto stands for Chula Photo Club .) Also, aticles on 'tagging' are subclass of articles on 'metadata'. But articles on 'metadata' are not essentially the articles on 'tagging'. 'Friends' versus 'people' is also another example. Bookmarks about my friends are of course bookmarks about people. But not all the people I know or found on the Internet (through search engines) are my friends. Ontology-assisted tagging sounds promising to solve this problem. In principle, this problem is partly related to...

Tips: Mac OS X: Full ANSI Color Support in Terminal.app

I'm trying to switch my Java development platform from Windows XP to Mac OS X Tiger. Wondering how to colorize the Terminal screen, I spent some time googling. From the discussions at the end of this page: macosxhints.com - Add full ANSI color support to Terminal.app Here's a summary of how to enable it: With bash shell as default, simply add export TERM=xterm-color [I prefer this for Linux compatibility] or export TERM=dtterm in the ~/.profile (single-user) or /etc/profile (system-wide) Color terminal is enabled. Use ' ls -G ' (the -G enables color output) to test. Add alias ls='ls -G' in the profile file for convenience. Keywords: mac-os-x , unix , terminal , shell , tips

Tip: Converting a CSV File into XML by Excel

I came across a problem to convert a historical data in comma-separated format (CSV) into a modern & more useful XML format. There are many ways to do such conversion. The most obvious one is to do it programmatically by writing a program to read CSV data and exporting it to an XML file by means of the Simple API for XML (SAX) or the Document Object Model (DOM) libraries. But I was too lazy to do it. I knew that Microsoft Excel 2003 supports exporting worksheets into XML data. I tried it out but found that it is not that simple -- we have to define an XML schema and bind each element to each column of the worksheet. So I went on researching. Finally, I found a very useful tool on MSDN: Excel 2003 XML Tools Add-in Version 1.1 ( download ). The Excel Add-in's "XML Tools -> Convert a Range to an XML List" menu command allows us to simply select a range in a worksheet (with or without first row as column names) -- with the advanced options to specify the XML root ...
