WIFI WPA Encryption with Ubuntu 6.10

Connecting to a WIFI network that uses WEP encription is a pretty straight forward task using UBUNTU, you only have to use the "Wireless Assistant" tool integrated with the system. However, when you try to connect to a network using WPA encryption things get more complicated. For some reason the "Wireless Assistant" do not let you select a other encryption than WEP.

After some research, i.e. google search, I found an entry in ubuntuforums.org that explain how to connect to WIFI networks that use WPA encryption. This process involves mainly editing text files, there is no "Windowzed" application to help:

In my case I'm using a network with DHCP activated, and my computer runs a KUBUNTU 6.10. My laptop is an old Toshiba Satellite M70-165 with an integrated WIFI adapter. My /etc/network/interfaces looks like this:

auto lo
iface lo inet loopback

auto eth1
iface eth1 inet dhcp
wpa-driver wext
wpa-ssid $your essid here$
wpa-ap-scan 1
wpa-proto WPA
wpa-pairwise TKIP
wpa-group TKIP
wpa-key-mgmt WPA-PSK
wpa-psk $your hex key code here$

Just follow the procedure explain in the forum, it's easy and it worked for me with at the first attempt.

XSLT with Java and Dom4j-1.6

Feeling geeky again!!

Today I´ll show you how to perform an XSLT (XSL transformation) on an XML file using Java and Dom4j. In contrast with the last Java/Dom4j post in this i´ll only show the class that acually performs the transformation. Dom4j is not able to perform the transformation on its own, it needs the help of JAXP:

 package com.julio.xml;

 import java.io.File;

 import java.io.FileWriter;
 import java.io.IOException; // dom4j import
 import org.dom4j.Document;
 import org.dom4j.DocumentException;

 import org.dom4j.io.SAXReader;
 import org.xml.sax.ErrorHandler;
 import org.xml.sax.SAXException;
 import org.xml.sax.SAXParseException;


 import javax.xml.transform.Transformer;
 import javax.xml.transform.TransformerConfigurationException;
 import javax.xml.transform.TransformerException;
 import javax.xml.transform.TransformerFactory;

 import javax.xml.transform.stream.StreamSource;

 import org.dom4j.io.DocumentResult;
 import org.dom4j.io.DocumentSource;
 import org.dom4j.io.DocumentSource;

 import org.dom4j.io.XMLWriter;
 import org.dom4j.io.OutputFormat;

 public class XmlTransformer {

  // The input XML file
  private File input;
  // The DOM document for the imput file

  private Document inputDoc;
  // Guess what!!!!
  private File output;

  // The xslt file
  private File transformation;

  public XmlTransformer(File input, File transformation) {

   this.input = input;
   this.transformation = transformation;

  }

  public File transform() throws IOException {

   // Need to create a factory using JAXP
   TransformerFactory factory = TransformerFactory.newInstance();

   try {
    // Now get a transformer using the facory
    Transformer transformer = factory.newTransformer(new StreamSource(

      transformation));
    // Convert the input file into a DOM document
    this.createDoc();

    // Dom4j support for trasnformations
    DocumentSource source = new DocumentSource(this.inputDoc);

    DocumentResult result = new DocumentResult();
    try {

     // OK lets do the actual transformation
     transformer.transform(source, result);
     // The rest is boiler plate code!!!

     Document outputDoc = result.getDocument();
     OutputFormat format = OutputFormat.createPrettyPrint();

     output = new File("output.xml");
     XMLWriter writer = new XMLWriter(new FileWriter(output), format);

     writer.write(outputDoc);
     writer.close();

    } catch (TransformerException e) {
     // TODO Auto-generated catch block

     e.printStackTrace();
    }
   } catch (TransformerConfigurationException e) {

    // TODO Auto-generated catch block
    e.printStackTrace();
   }

   return output;
  }

  private void createDoc() {

   SAXReader reader = new SAXReader(false);
   try {

    this.inputDoc = reader.read(this.input);

   } catch (DocumentException e) {
    // TODO Auto-generated catch block

    e.printStackTrace();
   }
  }

 }
