这是android模拟器的DDMS中的错误.
现在我的网络服务和代码看起来像这样.
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 {
@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;
}
}

现在我的Android代码.

import android.app.Activity;
import android.os.Bundle;

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();
}
}
}
请帮我.
提前致谢.
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，执行相反的操作以取回文件。
