Getting Onle One File when getting reponse through ksoap2 web service.

[Shashank Acharya]

Hello All,

I stuck in middle of the problem.

My question contains two problems
1.When tried to send multiple files to android app it shows OutOfMemoryException
2.When i tried to send four or five files it just write data of the first file.(Sending Response as Array of Bean FileData).

Now my main from which I made my web service.

package com.uks.webservice;

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

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

public class MultipleFilesImpl implements MultipleFiles {

	public FileData[] sendPDFs() {
		FileData fileData = null;
		File fileFolder = new File(
				"C:/eclipse/workspace/AIPWebService/src/pdfs/");

		File sendFiles[] = fileFolder.listFiles();

		DataHandler handler = null;
		char[] readLine = null;
		byte[] data = null;
		int offset = 0;
		int numRead = 0;
		InputStream stream = null;
		FileOutputStream outputStream = null;
		FileData[] filesData = new FileData[(int) sendFiles.length];
		try {
			System.out.println("Web Service Called Successfully");

			for (int i = 0; i < sendFiles.length; i++) {
				handler = new DataHandler(new FileDataSource(sendFiles[i]));
				fileData = new FileData();
				data = new byte[(int) sendFiles[i].length()];
				stream = handler.getInputStream();
				while (offset < data.length
						&& (numRead = stream.read(data, offset, data.length
								- offset)) >= 0) {
					offset += numRead;
				}
				readLine = Base64Coder.encode(data);
				offset = 0;
				numRead = 0;
				System.out.println("'Reading File............................");
				System.out.println("\n");
				// System.out.println(readLine);
				System.out.println("Data Reading Successful");

				fileData.setFileName(sendFiles[i].getName());
				fileData.setFileData(String.valueOf(readLine));

				readLine = null;
				// System.out.println("Data from bean " +
				// fileData.getFileData());

				outputStream = new FileOutputStream("D:/"
						+ sendFiles[i].getName());

				outputStream.write(Base64Coder.decode(fileData.getFileData()));

				outputStream.flush();
				outputStream.close();
				stream.close();

				filesData[i] = fileData;
				System.out.println(filesData[i].getFileName());
				// System.out.println(filesData[i].getFileData());
			}
			return filesData;
		} catch (FileNotFoundException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		} catch (Exception e) {
			e.printStackTrace();
		}
		return filesData;
	}
}

Interface:- MultipleFiles

package com.uks.webservice;

import java.io.FileNotFoundException;
import java.io.IOException;
import java.rmi.Remote;

public interface MultipleFiles extends Remote {
	public FileData[] sendPDFs() throws FileNotFoundException, IOException,
			Exception;
}

The Bean:- FileData having two properties viz. FileName & FileData.

package com.uks.webservice;

public class FileData {
	private String fileName;
	private String fileData;

	public String getFileName() {
		return fileName;
	}

	public void setFileName(String fileName) {
		this.fileName = fileName;
	}

	public String getFileData() {
		return fileData;
	}

	public void setFileData(String string) {
		this.fileData = string;
	}
}

Now the main android code through which I call web service getting response which array of bean FileData.

package com.uks.android.webservice;

import java.io.File;
import java.io.FileOutputStream;

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

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

public class PDFActivity extends Activity {
	private final String METHOD_NAME = "sendPDFs";
	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/MultipleFilesImpl";

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		// Base64 base64 = new Base64();
		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.bodyIn;
			// Object result = envelope.getResponse();
			Log.i("Result", result.toString());

			// Log.i("File Name", result.getProperty("fileName").toString());
			// Log.i("File Name", result.getProperty("fileData").toString());

			String[] values = null;
			String fileName = "";
			for (int i = 0; i < result.getPropertyCount(); i++) {
				values = new String[result.getPropertyCount()];
				Log.i("File Data", result.getProperty(i).toString());
				values[i] = result.getProperty(i).toString();
				if(i==1){
					 fileName = values[i];
				}
				Log.i("File Name", values[i]);
			}

			// String fileName = result.getProperty("fileName").toString();
			// String fileData = result.getProperty("fileData").toString();

			Log.i("File Name", fileName);
			// Log.i("File Data", fileData);

			File pdfFile = new File("new.pdf");

			// if(pdfFile)

			FileOutputStream outputStream = openFileOutput(pdfFile.toString(),
					MODE_PRIVATE);

			outputStream.write(Base64Coder.decode(values[0]));
			Log.i("File", "File Created");
			// textViewTwo.setText(result);
			// Object result = envelope.getResponse();
			// FileOutputStream outputStream = openFileOutput(name, mode)

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

Note:-I am using Apache Axis 1.4 for web service in eclipse ide. WSDL is generated via ide.

Please help me.
Thanks in Advance.
