Viewing PDF File Using Java

How to call the pdf file out using java program?

Answer:

Here is a sample program:

Java Code:

{
public static void main(String args[]) //main function
{
try //try statement
{
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + "c:\\chart.pdf"); //open the file chart.pdf

} catch (Exception e) //catch any exceptions here
{
System.out.println("Error" + e ); //print the error
}
}
}


Or


Using PDFBox to read the text from the PDF file:

Java Code:

I re-tested the code, and is working fine. Please check out what I have written:

import java.io.File;
import org.apache.pdfbox.pdmodel.PDDocument;
import org.apache.pdfbox.util.PDFTextStripper;

public class PdfBoxTest
{
public static void main(String args[])
{
try
{
PDDocument pddDocument=PDDocument.load(new File("a.pdf"));
PDFTextStripper textStripper=new PDFTextStripper();
System.out.println(textStripper.getText(pddDocumen t));
pddDocument.close();
}
catch(Exception ex)
{
ex.printStackTrace();
}
}
}

In the classpath, I have included the following jar files:

1) pdfbox-1.2.1.jar
2) fontbox-1.2.1.jar
3) commons-logging-1.1.1.jar

which could be downloaded form the internet

Protein Coated Disks…!!

Do not get shocked or tensed and spill out your cup of tea/coffee while reading or hearing news of “Hard disks getting obsolete” in the coming time.
Professor V Renugopalakrishnan, an Indian born scientist a BSc in Chemistry from Madras University and PhD in biophysics from Columbia/State University of New York, has claimed to develop “protein coated” DVDs that can make “Hard Disks” obsolete. His research makes an allegation to have developed a layer of protein made from tiny genetically altered microbe proteins which could store enough data of about 50 Terabytes. This protein is a “light activated protein” found in the membrane of a salt marsh microbe Halo-bacterium salinarum also known as bacteriorhodopsin (BR). It captures and stores sunlight to convert it to chemical energy. When light shines on BR, it is converted to a series of intermediate molecules each with a unique shape and color before returning to its ‘ground state‘.
Prof Renogopalakrishnan and his colleagues modified the DNA that produces BR protein to produce an intermediate that lasts for more than several years as the intermediates generally lasts for few hours or days.
He and his team asserts “This, ultimately broke grounds for a binary system to store data because of the energy levels i.e. ground state could be the zero and any of the intermediates could be the one. The protein-based DVDs will be able to store at least 20 times more than the Blue-ray and eventually even up to 50,000 gigabytes (about 50 terabytes) of information. You can pack literally thousands and thousands of those proteins on a media like a DVD, a CD or a film or whatever because the information is stored in proteins that are only a few nanometers across.” Protein Coated Disks would greatly increase storage over Holographic Versatile Disc optical disc systems. The technology uses the photosynthetic pigment bacteriorhodopsin created from bacteria.
The high-capacity storage devices will append an all new efficient dimension to the defense, medical and entertainment industries. In-fact in every field, at-least where the computers are used a medium to work and handle the work and development.
He also added that “You have a compelling need that is not going to be met with the existing magnetic storage technology.”
He also percepts with a scientific vision that “Science can be used and abused. Making large amounts of information so portable on high-capacity removable storage devices like “Protein Coated Disks” will make it easier for information to fall into the wrong hands. Information can be stolen very quickly. One has to have some safeguards there”.
Working with the Japanese NEC Corporation, Renugopalakrishnan’s team created a prototype device and estimated in July, 2006 that a USB disk would be commercialized in 12 months and a DVD in 18 to 24 months.
The findings were presented at the International Conference on Nano science and Nanotechnology in Brisbane.
Still the concept is at the theoretical stage under the process of development but yes it is something which we cannot oversee or brushoff.
Just imagine the time when this concept will turn into a reality we all would look at that disk and say “Oh God, proteins….!!! ” The idea itself for the “Protein Coated Disks” excites us. :) :P
Hope that such “Protein Coated Disks” helps us revolutionize IT in the best way we can..!!

Second-hand phones reveal sensitive personal data

Analysts recover SMS, browsing history and medical information from second-hand handsets bought at shops which claim to delete data before sale

Your old mobile phone can reveal sensitive data such as email passwords, medical records or personal text messages even after data is deleted, reveals a Channel 4 investigation.
Journalists bought three used mobile phones from the high street second-hand shop CEX, which tells customers when they sell old handsets that all data will be erased.
Analysts were able to recover 5,000 files from one of the devices using specialist software, revealing SMS sent between the owner and his girlfriend and his browsing history, including visits to p**n websites.
Other devices included an email address and password for a work account, full name and postal address and medical records. Although the data had been deleted it was still recoverable in many cases.
A CEX spokesman told Channel 4: “As technology evolves so do our systems and we are currently rolling out a new procedure that improves on the current erasing technique used in the second hand phone market.”

SensePost, the security firm who recovered the data, said in a blog post that it was “trivial” to recover large amounts of data from mobile phones and said that unencrypted handsets were “easy game”.
“iPhone devices encrypt their data by default, which makes it hard (almost impossible) to recover data after performing a factory reset,” it said.
“Android devices by default have no encryption, which means that somebody (like us) could easily recover large amounts of supposedly deleted data. It's a good idea to keep your phone encrypted.
“Both Windows phone 8 and BlackBerry allow optional encryption to be configured, but this is not enabled by default. Windows phone 7 does not support encryption of the core filesystem.
“If you have an existing phone that you're about to sell we'd recommend you encrypt the phone twice after resetting it to factory default (once to destroy your data, the second time to destroy the key used for the first round).”
