reading a pdf file using httpClient and itextpdf

[Hellsing]

Hi,

I am trying to write a java application that can read part of a pdf document online (or just for testing purposes, reading from my wamp server). For the most part, it all works but the pdfreader doesn't do the conversion well and prints symbols

Here is the code I was using:

import org.apache.http.client.*;
import org.apache.http.client.methods.*;
import org.apache.http.impl.client.BasicResponseHandler;
import org.apache.http.impl.client.DefaultHttpClient;
import org.apache.http.client.ResponseHandler;
import com.itextpdf.text.Document;
import com.itextpdf.text.pdf.PdfImportedPage;
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.parser.PdfTextExtractor;
import java.io.File;
import java.lang.System;



//NOTE:




import java.io.*;

import javax.xml.ws.http.HTTPException;

public class HttpConn {
	
private static String url = "http://127.0.0.1/showme/IJERTV1IS3191.pdf";
	
	
	public static void main(String[] args) {
		
		
		
		System.getProperties();
		// Create an instance of HttpClient
		HttpClient client = new DefaultHttpClient();
		
		// Create a method instance
		HttpGet method = new HttpGet(url);
		
		//Provide custom retry handler is necessary
		//:OC:method.getParams().setParameter(HttpConnectionParams.RETRY_HANDLER, new DefaultHttpRequestRetryHandler(3, false));
		
		
		try{
		//execute the method
			
			
			System.out.println("executing request " + method.getURI());

            // Create a response handler
            ResponseHandler<String> responseHandler = new BasicResponseHandler();
            String responseBody = client.execute(method, responseHandler);
            
            PdfReader reader = new PdfReader(responseBody);
            int n = reader.getNumberOfPages();
            
            String str=PdfTextExtractor.getTextFromPage(reader, 2); //Extracting the content from a particular page.
                      System.out.println(str);
                 reader.close();
           // System.out.println("----------------------------------------");
          //  System.out.println(responseBody);
            //System.out.println("----------------------------------------");
			
            //HttpResponse response = new BasicHttpResponse(HttpVersion.HTTP_1_1, HttpStatus.SC_OK, "OK");
            //System.out.println(response.getProtocolVersion());
            //System.out.println(response.getStatusLine().getStatusCode());
            //System.out.println(response.getStatusLine().getReasonPhrase());
            //System.out.println(response.getStatusLine().toString());
            
			
			} catch (HTTPException e) {
				//protocol and transport protocol issues 
					
					System.err.println("Fatal protocol violation: " + e.getMessage());
					e.printStackTrace();
					
				} catch (IOException e) {
				
					System.err.println("Fatal transport error: " + e.getMessage());
					e.printStackTrace();
				} finally {
				
					//release the connection
					method.releaseConnection();
				
		}
	}


}

Hi all,

tried something different. tried converting the inputstream to a byte array which i could pass to the pdfreader but i get no output

import java.net.*;
import java.io.*;
import com.itextpdf.text.Document;
import com.itextpdf.text.pdf.PdfImportedPage;
import com.itextpdf.text.pdf.PdfReader;
import com.itextpdf.text.pdf.parser.PdfTextExtractor;
import org.apache.commons.io.*;

public class urlconn {
    public static void main(String[] args) throws Exception {
        URL oracle = new URL("http://127.0.0.1/showme/dss.pdf");
        URLConnection yc = oracle.openConnection();
        yc.setDoInput(true);
        
        InputStream is = yc.getInputStream();
        byte[] b = new byte[2028];
        b =IOUtils.toByteArray (yc.getInputStream());
        int len;
        while ((len = is.read(b)) != -1) {
        	
        	 PdfReader reader = new PdfReader(b);
        	 String str=PdfTextExtractor.getTextFromPage(reader, 1);
        	 System.out.println(str);
        }
       
    }
}
