这是android模拟器的DDMS中的错误.

现在我的网络服务&代码看起来像这样.

码：-

package com.uks.webservice;import java.io.fileNotFoundException;  import java.io.IOException;  import java.rmi.Remote;  public interface Sendpdf extends Remote {    public String[] sendpdf() throws fileNotFoundException, IOException,            Exception;}

创建Web服务的主类： –

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 {@OverrIDepublic 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;}}

请帮我.

提前致谢.

解决方法:

您需要将文件转换为字节数组并将其传递给服务器上的服务执行相反的 *** 作以获取文件.
