Hi Bill,

Can I switch to axis 2 for json response?

Sorry for that I haven't mentioned my client.Basically my client is mobile app in android.

I surely search for jersey.

Thanks for your reply.

I am not getting you clearly at the point "using file transfer protocol" please clarify the question in lucid manner.

Hello Friends,

Thanks In Advance.

Hi Ivan,shivendra

@shivendra I wrote a plain logic for it & my eclipse ide has made fine wsdl for me.

@Ivan I am using Apache Axis web service for it. My question is that I want to collect files of total 1 mb from specific folder.

Here is my code to retrieve that. I am easily getting that.

FileData fileData = null; File fileFolder = new File("C:/eclipse/workspace/AIPWebService/src/pdfs/"); File sendFiles[] = fileFolder.listFiles(); while (size <= 1048576) { size += sendFiles[j].length(); j++; } Object[] obj = new Object[j]; try{ System.out.println("Web Service Called Successfully"); for (int i = 0; i < j; i++) { /*File Reading & Required File Writing Stuff*/ } return obj; } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); }

Now my question is
1. If the web service is called how can I know that it first call or second call.i.e if when server has started first time the web service is called,if after some time web service is called second time how can I track that.
2. How to track that this many files are send to client & next are remaining.i.e if in first call I send total of 4 files(having 1 mb of size),then in second call I have to send files from 5th file upto my required size.

Can you please help in this.

Please ask me if it not clear.
Thanks for reply.

Hello All,

My question is that I want to send pdf files through web service with condition that only 1mb of files are taken from that folder containing many files.

Please help me to resolve this question.I am new to web service.
Ask me again if it not clear.
Thanks In Advance.

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.

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.

I think you should take your file in following way:-
/* Above Code*/ File clip = new File(Environment.getExternalStorageDirectory() + "/video1.mp4"); /*Rest Code*/

Hope that works for you.It works for me to read every file from sdcard.

Thanks Ulf Dittmer Dude
