The prerequisite of this sample is the iText library which needs to be downloaded from:

http://itextpdf.com/

iText is an ideal library for developers looking to enhance web- and other applications with dynamic PDF document generation and/or manipulation.
 

• Download the iText1.2.X.jar library and add to the application server library path.

package com.sample;

import org.jboss.ejb3.annotation.Management;
import org.jboss.ejb3.annotation.Service;

@Service(objectName = "textToPdf:service=PDFConverter")
@Management(PDFConverter.class)
public class PDFConverterService implements PDFConverter{
 
		// Lifecycle methods
		public void create() throws Exception {} 

		@Override
		public void createReportPDF(String inputfileName,String outputfileName) {
			 try {
				PDFCreator.createReportPDF(inputfileName,outputfileName);
			} catch (Exception e) {
				 
				e.printStackTrace();
			} 
			
		}
		 	 	 
}

package com.sample;

public interface PDFConverter {
	public void createReportPDF(String inputfileName,String outputfileName);	
}

The real class which does the job of converting a text file into a PDF formatted table is PDFCreator which basically reads the input file name stores the content into an Array using the "|" as separator between fields. 

package com.sample;

import java.io.*;
import java.util.ArrayList;
import java.util.StringTokenizer;

import com.lowagie.text.*;
import com.lowagie.text.pdf.*;

public class PDFCreator {

 
	public static void createReportPDF(String inputfileName, String outputfileName) throws DocumentException, IOException {
		  ArrayList mainList = new ArrayList();
          
		  // READ TEXT FILE
		  BufferedReader in = new BufferedReader(new FileReader(inputfileName));
		  String line;
		  
		  int rows=0;
		  int columns=0;
		  
		  while((line = in.readLine()) != null) {  
		      ArrayList subList = new ArrayList();
			  StringTokenizer st = new StringTokenizer(line,"|");   
			  while (st.hasMoreElements()) {
				 String cell = st.nextToken();
				 subList.add(cell);
				 columns=subList.size();
		      }
			  mainList.add(subList);
		  }	  
			  
		  in.close();     
		  rows=mainList.size();
		  
			
		// CREATE PDF DOCUMENT 
		Document document = new Document();
		PdfWriter.getInstance(document, 
			new FileOutputStream(outputfileName));
		document.open();
		
		PdfPTable table = new PdfPTable(columns); 
        for (int i=0;i<mainList.size();i++) {
        	ArrayList subList = (ArrayList)mainList.get(i);
        	for (int y=0;y<subList.size();y++) {
        		String cell = (String)subList.get(y);
        		table.addCell(cell);
        	}
        }
		
		 
		document.add(table);		
		document.close();

		
	}
     
}

This is a sample of input file:

column1|column2|column3
aaaaaaa|bbbbbbb|ccccccc
ddddddd|eeeeeee|fffffff
ggggggg|hhhhhhh|iiiiiii

This is the PDF output:
