java.lang.NoClassDefFoundError: org/apache/axis/client/Service

[fight_flight]

我要做一个在手机上调用webservice的程序（使用wsdl），调用的程序在webProject中可以正常完成。但我建立一个J2me的J2ME Midlet Suite时把调用的项关代码考入Midlet中，并已把相应jar包导入工程，但运行是提示错误：
java.lang.NoClassDefFoundError: org/apache/axis/client/Service

Execution completed.
请问高手要怎样解决呢？
Midlet程序如下：

import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.TextBox;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;
//以下三个为调用webservice的包
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;



public class Hello extends MIDlet implements CommandListener{
public void commandAction(Command c, Displayable d) {
		if(c==comm){
			//调用webservice，测试数据是可以得到结果的数据
			String[] s=call("2010-4-5", "2010-6-3", "1587");
			if(s.length>0){
				textbox1.setString(s[0]);
				System.out.println(s[0]);
			}
		}
		
	}

private TextBox textbox1;
private Command comm=new Command("TEST",Command.SCREEN,1);
	public Hello() {
		super();
		textbox1=new TextBox("测试","textbox1",20,0);
	}

	protected void destroyApp(boolean arg0) throws MIDletStateChangeException {

	}

	protected void pauseApp() {

	}

	protected void startApp() throws MIDletStateChangeException {
		Display.getDisplay(this).setCurrent(textbox1);
		textbox1.addCommand(comm);
		textbox1.setCommandListener(this);
	}
	//调用函数，已通过测试函数本身没问题
	public String[] call(String startDate,String endDate,String cardid){
		try
		{
		String endpoint ="http://localhost:8080/Axis/foodWebService.jws";
		Service service = new Service();
		Call call = null;
		call = (Call) service.createCall();
		call.setOperationName(new QName("http://localhost:8080/Axis/foodWebService.jws",
				                        "function"));
		call.setTargetEndpointAddress(new java.net.URL(endpoint));
		String[] ret = (String[]) call.invoke(new Object[]{startDate,endDate,cardid});
		return ret;
		}
		catch (Exception ex)
		{
			System.out.println(ex.getMessage());
			return null;
		}
	}
}

很明显 你apache axis2相关包没有加入进来

[fight_flight]

包加了啊我也不知道具体加那些，所以把相关的都添加了。
axis.jar
axis-ant.jar
commons-discovery-0.2.jar
....
但问题依旧？？？

[fight_flight]

我在这个工程中新建了另一个普通的类
再类中调用call函数，输出
- Unable to find required classes (javax.activation.DataHandler and javax.mail.internet.MimeMultipart). Attachment support is disabled.
（是返回的结果）
canteen1
10
5.3
2010-5-20 20:37:10
可以返回结果，但上面会输出一行，怎么回事啊

J2ME不用那些包吧？

你的服务器才需要啊

[yojiwei]

如果类似的包有多个，也会起冲突的，你只需要确定它需要的包，导入即可。
导入的时候请注意，版本。。。

喔又改了一下。j2me里面有两个文件
callService.java 代码

import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
public class callService {
	public String[] call(String startDate,String endDate,String cardid){
		try
		{
		String endpoint ="http://localhost:8080/Axis/foodWebService.jws";
		Service service = new Service();
		Call call = null;
		call = (Call) service.createCall();
		call.setOperationName(new QName("http://localhost:8080/Axis/foodWebService.jws",
				                        "function"));
		call.setTargetEndpointAddress(new java.net.URL(endpoint));
		String[] ret = (String[]) call.invoke(new Object[]{startDate,endDate,cardid});
		return ret;
		}
		catch (Exception ex)
		{
			System.out.println(ex.getMessage());
			return null;
		}
	}
	public static void main(String[] args)
	{
		callService call=new callService();	
	String[] ret =call.call("2010-4-5", "2010-6-3", "1587");
	for(int i=0;i<ret.length;i+=4){
		System.out.println(ret[i]);
		System.out.println(ret[i+1]);
		System.out.println(ret[i+2]);
		System.out.println(ret[i+3]);
	}
	}
}

单独运行此文件可以正确得到结果。
另一个文件为Hello.java代码

import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.TextBox;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;
import callService;

public class Hello extends MIDlet implements CommandListener{
private TextBox textbox1;
private Command comm=new Command("TEST",Command.SCREEN,1);
	public Hello() {
		super();
		textbox1=new TextBox("测试","textbox1",20,0);
	}
	protected void destroyApp(boolean arg0) throws MIDletStateChangeException {

	}
	protected void pauseApp() {

	}
	protected void startApp() throws MIDletStateChangeException {
		Display.getDisplay(this).setCurrent(textbox1);
		textbox1.addCommand(comm);
		textbox1.setCommandListener(this);
	}
	public void commandAction(Command c, Displayable d) {
		if(c==comm){
			//调用webservice，测试数据是可以得到结果的数据
			callService ca=new callService();
			String[] s=ca.call("2010-4-5", "2010-6-3", "1587");
			if(s.length>0){
				textbox1.setString(s[0]);
				System.out.println(s[0]);
			}
		}	
	}
}

运行此程序，然后单击手机右上角按钮之后显示下面错误
