不同MIDlet套件之间共享RecordStore对象【j2me开发精解第四章】

自学看《j2me开发精解》第四章4.4.3，却不知如何运行书上的程序，ShareMIDlet.java程序代码：
package com.j2medev.chapter4;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.rms.*;

public class ShareMIDlet extends MIDlet {
private RecordStore rs = null;

public void startApp() {
try{
//创建可共享的RecordStore，并向其中写入一条记录hello world。
rs = RecordStore.openRecordStore("test",true,RecordStore.AUTHMODE_ANY, false);
String s = "hello world";
byte[] data = s.getBytes();
rs.addRecord(data, 0,data.length);
}catch(RecordStoreException ex){
ex.printStackTrace();
}
Form form = new Form("共享");
form.append("写入hello word");
Display.getDisplay(this).setCurrent(form);
}

public void pauseApp() {
}

public void destroyApp(boolean unconditional) {
try{
rs.closeRecordStore();
}catch(RecordStoreException ex){
ex.printStackTrace();
}
}
}
jad设置：
MIDlet-1: ShareMIDlet, ,com.j2medev.chapter4.ShareMIDlet
MIDlet-Jar-Size: 1822
MIDlet-Jar-URL: sharerecord1.jar
MIDlet-Name: database
MIDlet-Vendor: j2medev
MIDlet-Version: 1.0
MicroEdition-Configuration: CLDC-1.1
MicroEdition-Profile: MIDP-2.1
AccessMIDlet.java代码如下：
package com.j2medev.chapter4;
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.rms.*;

public class AccessMIDlet extends MIDlet {
private RecordStore rs = null;

public void startApp() {
String s = "";
try{
//打开另外套件中的RecordStore对象并读取内容。
rs = RecordStore.openRecordStore("test", "j2medev", "database");
s = new String(rs.getRecord(1));
}catch(RecordStoreException ex){
ex.printStackTrace();
}
Form form = new Form("读取记录");
form.append(s);
Display.getDisplay(this).setCurrent(form);
}

public void pauseApp() {
}

public void destroyApp(boolean unconditional) {
try{
rs.closeRecordStore();
}catch(RecordStoreException ex){
ex.printStackTrace();
}
}
}
请问这个jad如何设置，这两个套件是放在一个项目里还是分开为两个项目，若为一个项目该如何设置.
本人是直接导入这两个项目，最后运行后 rs = RecordStore.openRecordStore("test", "j2medev", "database");出错。
