A way to keep track of blogs I'm interested in.

8:58 AM / Comments (3) / by Kevin Vu

There are many free and good RSS Reader out there such as NewszCrawler, FeedDemon, Bloglines, etc. (more ...) but I like Google Reader. It has a simple, clean interface, easy to manage and the best part is I can just use my existing gmail account to login and don't have to register a new account for a new service.

1. Login to Google Reader: http://reader.google.com
javascript:void(0)
2. Click on Add A Subscription on the left panel -> Paste a feed URL(like below)-> Click Add

Reproducing Eclipse WTP Bug#: 173912

9:33 PM / Comments (2) / by Kevin Vu

This is my first time I try to reproduce an Eclipse WTP Bug and It was successfully reproduced the same just as Ian He, the reporter, reported.




Steps To Reproduce: (Bug#: 173912)
1. Create a dynamic web app named app1. Aim it at an APP server.
2. Create a class, com.whatever.MyClass, add the following methid, and save and
close.
public String getGreeting() {
return "Number one!";
}
3. Create a JSP, index.jsp, in the project's Web Content folder. Add the
following use bean directive just before the "META" tags:
<jsp:useBean id="bean" class="com.whatever.MyClass"
type="com.whatever.MyClass"></jsp:useBean>
Add the following expression in the BODY:
<p><%=bean.getGreeting()%></P>
4. Create a nother dynamic web project named app2.
5. Create a jsp index.jsp in app2 and also create com.whatever.MyClass and
change "Number one!" to "Number two!".
6. Set a breakpoint on the bean expression in app2's index.jsp.
7. Add both projects to the server.
8. Restart the server in debug mode.
9. Run app2's index.jsp on the server.
10. When the breakpoint is hit, select "bean" in the Variables view in the
debugger. Do <context menu>-->Open declared type. The Java editor will open,
but on app1's com.whatever.MyClass.

I've just finished watching this documentary. Very Interesting, entertain and informative. The pace is quick, make the 85 minutes time length went fast. Give you a good understanding about Linux and Open Source movements. Linus Torvalds, Richard Stallmans, Eric Raymond, etc. , those guys are so devoted and just so awesome with their passions and intelligences.

WTP Getting Started!

6:31 PM / Comments (1) / by Kevin Vu

Finally I have finished registering and setting up all my pages and software. It was fun bookmarking and keeping track all my accounts :D. I'm really eager to dig into WTP Project right now but, I think, It would be best if I spend this week reviewing and sharpening my Java skills. Long break sure made me slow :(.
