After many years running on my home server this blog is now hosted at lylix. I went to them because it was the only Gentoo/Funtoo VPS provider I could find:)

Book Meme

Book Meme Floating around, so mine is:

Save the file and reboot the system for the settings to take effect.

in Asterisk, The Future of Telephony

The Rules for this meme are:

Grab the nearest book.
Open it to page 56.
Find the fifth sentence.
Post the text of the sentence in your journal along with these instructions.
Don’t dig for your favorite book, the cool book, or the intellectual one: pick the CLOSEST.

All your video are belong to us.

A Wiki for Gentoo

Gustavo Felisberto — Tue, 21 Oct 2008 22:40:57 +0000

A long long time ago I voiced about the need for a wiki in the Gentoo project. In those days Gentoo-Wiki was starting up.
For some reason or other people inside the project felt that having the users producing documentation was a bad idea. For some other reasons that I never understood the gentoo-wiki.com becamed a banned issue, and Gentoo developers were advised not to mention, and not to link to him. I wrote an extensive article about Gentoo on the Efika board that got some raised eyebrows because it was written on the Wiki.

Now Gentoo Wiki has been down for a few days. And according to the backup page it does not seem a fix is going to happen soon.

If we had taken this project under an umbrella a long time ago our users would not be missing on this very important resource.

Struts2 ActionMessages and redirect

Gustavo Felisberto — Wed, 15 Oct 2008 15:40:45 +0000

Lets say you have an Action that lists some items. And you have another action that adds items.

If you add an Item you can either just show a “blank” with the “All ok with addition” or even smarter is to use the ListAction. But how do you give feedback to the user that the addition was ok? Simple you just addActionMessage(”Item added ok”); on the first action and the message will be rendered by the s:actionmessage in the jsp of the second. Right? Wrong!!
Struts will “eat” ActionMessages and ActionErrors between the first and second action. But Glindholm solved the problem with a simple Interceptor.

Struts 2 under IntelliJ IDEA 8.0M1

Gustavo Felisberto — Fri, 03 Oct 2008 13:42:56 +0000

If you like IDEA and use Struts 2 you can be happy to know that 8.0 release comes with a new Struts 2 plugin. There is a small tutorial on how to use it but it has some errors.
First the Action class should extend ActionSupport hand have proper setter methods:

package hello;
import com.opensymphony.xwork2.ActionSupport;
public class HelloWorld extends ActionSupport {
    private String username;
    private String message;
    public String getMessage(){
        return message;
    }
    public String execute(){
        message = "Hello, " + username + ".";
        return SUCCESS;
    }
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
}

Second the JSP file can have a proper action:

< %@ page contentType="text/html;charset=UTF-8" language="java" %>
< %@ taglib prefix="s" uri="/struts-tags" %>
>
  >>Simple jsp page>>
  >
		Struts 2 Message:  :property value="message" default="Guest." />
		 :form method="GET" action="HelloWorld">
			Enter your name: :textfield name="username" />
			 :submit value="Submit" />
		>
  >
>

And finally struts.xml can have the Action declared without the ugly unRESTFUL .action:

< ?xml version="1.0" encoding="UTF-8"?>
 
< !DOCTYPE struts PUBLIC
  "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
  "http://struts.apache.org/dtds/struts-2.0.dtd">
 
>
     name="/" extends="struts-default">
		 name="HelloWorld" class="hello.HelloWorld">
			 name="success">/index.jsp>
		>
	>
>

I really like IDEA when it comes to Java codding, and I can live with the quirks of the Struts 2 support. But one thing that makes me steam is the fact that I have to un-deploy and deploy the application for each change I make. That steals me hours every week.
