我正在尝试从我正在通过axis2 Web 服务访问的android device.my java 方法调用一些java 方法。

这是我的完整 Java 类，因为我编写了两个从 Adnroid 设备调用的方法。不知何故，它只是成功调用 get_wav_byte() 方法，但对于另一种方法，它给了我如下错误

在 java.lang.Thread.run(Thread.java:662) 引起：java.lang.NoClassDefFoundError: edu/cmu/sphinx/util/props/ConfigurationManager

这是我在识别波（字符串波路径）方法中使用的外部 jar 库中的类。我还检查了 edu/cmu/sphinx/util/props/ConfigurationManager 在 jar 文件 m 中是否可用，包括仍然给我错误。我给你我的 java 和 android 的完整代码如下

JAVA方法：

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.File;
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;


 }



}

我能理解的是它是如何不工作的，因为我在该公共静态字符串识别波（字符串波路径）方法中使用外部 jar 文件。

我已经搜索了很多，但仍然没有好的指导。

希望你能帮我..

检查以确保您的外部 jar 文件包含在您的构建路径中以及您的 libs 文件夹中。如果您没有 libs 文件夹，您可以在项目的根目录中创建一个。然后将您的 jar 文件复制并粘贴到此位置。然后右键单击 Eclipse 中的 jar 文件，Build Path然后单击Add To Build Path. 如果您的 libs 文件夹中有 jar 文件，则不会出现任何编译器错误。但这仅适用于编译时间。如果 jar 不在构建路径中，它将在运行时失败。
