Sending a pdf file to client from server through web service

[Shashank Acharya]

Hello friends,

Can anyone solve my question as I am new to webservice.
My question is

I want to build a web service which when called from client side sends pdf files to client.

Now can some one please solve my error.

Now my web service & code looks likes this.

Code:-

Main Class from which web service is created:-

package com.uks.webservice;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;

import javax.activation.DataHandler;
import javax.activation.FileDataSource;

import sun.misc.BASE64Encoder;

public class SendPDFImpl implements SendPDF {

@Override
public String[] sendPDF() {

    String[] pdfFile = new String[2];
    BASE64Encoder encoder = new BASE64Encoder();
    File file = new File(
            "C:/eclipse/workspace/AIPWebService/src/test.pdf");
    DataHandler dh = new DataHandler(new FileDataSource(file));
    String readLine = null;
    byte[] data = new byte[(int) file.length()];
    int offset = 0;
    int numRead = 0;
    InputStream stream = null;
    try {
        System.out.println("Web Service Called Successfully");
        stream = dh.getInputStream();
        // BufferedReader bufferedReader = new BufferedReader(
        // new InputStreamReader(stream));
        while (offset < data.length
                && (numRead = stream.read(data, offset, data.length
                        - offset)) >= 0) {
            offset += numRead;
        }
        readLine = encoder.encode(data);
        // while ((readLine = bufferedReader.readLine()) != null) {
        System.out.println("'Reading File............................");
        System.out.println("\n");
        System.out.println("Data Reading Successful");

        pdfFile[0] = file.getName();
        pdfFile[1] = readLine;

        stream.close();

    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
    return pdfFile;
}

}

And Now My Android Code.

package com.uks.android.webservice;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.AndroidHttpTransport;

public class PDFActivity extends Activity {
private final String METHOD_NAME = "sendPDF";
private final String NAMESPACE = "http://webservice.uks.com/";
private final String SOAP_ACTION = NAMESPACE + METHOD_NAME;
private final String URL = "http://192.168.1.123:8080/AIPWebService/services/SendPDFImpl";

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    TextView textViewOne = (TextView) findViewById(R.id.textViewOne);
    TextView textViewTwo = (TextView) findViewById(R.id.textViewTwo);
    try {
        SoapObject soapObject = new SoapObject(NAMESPACE, METHOD_NAME);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.setOutputSoapObject(soapObject);

        textViewOne.setText("Web Service Started");
        AndroidHttpTransport httpTransport = new AndroidHttpTransport(URL);

        httpTransport.call(SOAP_ACTION, envelope);

        SoapObject result = (SoapObject) envelope.getResponse();
        textViewTwo.setText(result.toString());
        // Object result = envelope.getResponse();
        // FileOutputStream outputStream = openFileOutput(name, mode)

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

}

Please help me.

Thanks in Advance.
