I am Trying to Call some java method from the android device.my java method i am accessing through axis2 web service.
Here Is my full Java class in that i had Written two Methods to call From Adnroid Device .And Somehow Its just calling get_wav_byte()method Successfully but for another method its giving me error as follows
at java.lang.Thread.run(Thread.java:662) Caused by: java.lang.NoClassDefFoundError: edu/cmu/sphinx/util/props/ConfigurationManager
this is the class in my external jar library that i m using in recognize_wave(String wavePath) method. I have Also Checked that the edu/cmu/sphinx/util/props/ConfigurationManager is available in jar file m including stilll its giving me error.I am givng you my full code of java and android as follows
JAVA METHOD :
package edu.cmu.sphinx.demo.transcriber;
import edu.cmu.sphinx.frontend.util.AudioFileDataSource;
import edu.cmu.sphinx.recognizer.Recognizer;
import edu.cmu.sphinx.result.Result;
//import edu.cmu.sphinx.util.props.ConfigurationManager;

import java.io.FileOutputStream;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import javax.sound.sampled.UnsupportedAudioFileException;
/** A simple example that shows how to transcribe a continuous audio file that has multiple utterances in it. */
public class Transcriber {
// private static final String PATH = "file:///D:\\Sound\\";
@SuppressWarnings("null")
public static String recognize_wave(String wavePath) throws MalformedURLException{
String resultText="";
URL audioURL;
audioURL = new URL(wavePath);
URL configURL = Transcriber.class.getResource("config.xml");
ConfigurationManager cm = new ConfigurationManager(configURL);
Recognizer recognizer = (Recognizer) cm.lookup("recognizer");
/* allocate the resource necessary for the recognizer */
recognizer.allocate();
// configure the audio input for the recognizer
AudioFileDataSource dataSource = (AudioFileDataSource) cm.lookup("audioFileDataSource");
dataSource.setAudioFile(audioURL, null);
// Loop until last utterance in the audio file has been decoded, in which case the recognizer will return null.
Result result;
while ((result = recognizer.recognize())!= null) {
resultText = result.getBestResultNoFiller();
System.out.println(resultText);
}
return resultText;
}
public String get_wav_byte(byte[] wavbite,String path) throws IOException
{
String result1="null";
//return result1;
final String PATH = "file:///D:\\Sound\\";
//System.out.println(bhavik1111);
try
{
File dstFile = new File(path);
FileOutputStream out = new FileOutputStream(dstFile);
out.write(wavbite, 0, wavbite.length);
out.close();
}
catch (IOException e)
{
System.out.println("IOException : " + e);
}
try {
result1=recognize_wave(path);
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();

return result1;

What i can understand is Some How Its not Working Because I am Using External jar file in that public static String recognize_wave(String wavePath) Method.
I have Search a Lot But Still No Good Guidance Is yet Available..
Hope You can Help me..
thanks in advance ..
