我在SUN的J2EE上发布一个简单的EJB不成功

[文艺青年2]

我用的J2EE1.3beta支持EJB2.0
我编写的是EJB1.1的例子,J2EE的deployTool已经正确载入我的程序

然后我进入菜单Tool—>Deploy进行配置，提示错误如下：
There was a deployment error

java.rmi.ServerException: RemoteException occurred in server thread;nested is ..
java.rmi.RemoteException: Error processing ejb jar:Compilation failed

Please refer to
<J2EE_HOME>/logs/<machine-name>j2ee/j2ee/error.log
for more information. Please verify your Application with the Verifier tool

[文艺青年2]

以下是error.log文件里的内容:
Compilation failed.

可我看不明白怎么除错

[bobosji]

我记得Deploytool上有个校验的按钮的，你校验了没有？

[文艺青年2]

大家帮帮忙啊

[nintyuui]

程序对不对.
如果程序里的写法不符合EJB规范的话DEPLOY时也会出错.

[文艺青年2]

我的代码如下(你帮我看看好吗?):
//==============================================================================
1、远程接口 cabin.java
package com.titan.cabin;

import java.rmi.RemoteException;

public interface Cabin extends javax.ejb.EJBObject {
public String getName() throws RemoteException;
public void setName(String str) throws RemoteException;
public int getDeckLevel() throws RemoteException;
public void setDeckLevel(int level) throws RemoteException;
public int getShip() throws RemoteException;
public void setShip(int sp) throws RemoteException;
public int getBedCount() throws RemoteException;
public void setBedCount(int bc) throws RemoteException;
}
//==============================================================================
2、Bean类： CabinBean
package com.titan.cabin;

import javax.ejb.EntityContext;

public class CabinBean implements javax.ejb.EntityBean {

public int id;
public String name;
public int deckLevel;
public int ship;
public int bedCount;

public CabinPK ejbCreate(int id){
this.id = id;
return null;
}
public void ejbPostCreate(int id){
// Do nothing. Required.
}
public String getName(){
return name;
}
public void setName(String str){
name = str;
}
public int getShip(){
return ship;
}
public void setShip(int sp) {
ship = sp;
}
public int getBedCount(){
return bedCount;
}
public void setBedCount(int bc){
bedCount = bc;
}
public int getDeckLevel(){
return deckLevel;
}
public void setDeckLevel(int level ){
deckLevel = level;
}

public void setEntityContext(EntityContext ctx){
// Not implemented.
}
public void unsetEntityContext(){
// Not implemented.
}
public void ejbActivate(){
// Not implemented.
}
public void ejbPassivate(){
// Not implemented.
}
public void ejbLoad(){
// Not implemented.
}
public void ejbStore(){
// Not implemented.
}
public void ejbRemove(){
// Not implemented.
}
}
//==============================================================================
3、远程接口： CabinHome
package com.titan.cabin;

import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.FinderException;

public interface CabinHome extends javax.ejb.EJBHome {

public Cabin create(int id)
throws CreateException, RemoteException;

public Cabin findByPrimaryKey(CabinPK pk)
throws FinderException, RemoteException;
}
//==============================================================================
4、主键类： CabinPK
package com.titan.cabin;

public class CabinPK implements java.io.Serializable {
public int id;

public int hashCode( ){
return id;
}
public boolean equals(Object obj){
if(obj instanceof CabinPK){
return (id == ((CabinPK)obj).id);
}
return false;
}
public String toString(){
return String.valueOf(id);
}

}
//==============================================================================
5、ejb-jar.xml
<?xml version="1.0" ?>
<!DOCTYPE ejb-jar (View Source for full doctype...)>

目录结构是这样的
com—titan—cabin

META-INF\ejb-jar.xml
//==============================================================================
生成cabin.jar
jar cf cabin.jar com\titan\cabin\*.class META-INF\ejb-jar.xml

请各位大侠帮忙，小弟要用EJB吃饭找工作的呀

[文艺青年2]

TO:bobosji(波波司机)　
我用verifier校验过了,没错!!!

[bobosji]

看看你的log文件里写的什么，再校验一下你的bean

[nintyuui]

在EntityBean中必须写．
在sessionBean中可以不写．
只在CabinHome中写不过必须在CabinBean中也定义．

[文艺青年2]

哦,我试试

[文艺青年2]

哎,为什么没人帮助我
如果有人帮我解决了问题,我愿意支付RMB

[bobosji]

[e-mail]
把你的文件邮给我，我试试看

[文艺青年2]

好，多谢了

[nintyuui]

我按你的程序DEPLOY了
报D:\j2sdkee1.2.1\repository\DIY28-2000J\gnrtrTMP\cabin\CabinHomeImpl.java:50: cla
ss CabinBean 中未找到方法 ejbFindByPrimaryKey(CabinPK)。
primaryKeys = ejb.ejbFindByPrimaryKey( param0);
是你在你的CabinBean中没有定义ejbFindByPrimaryKey,如果你使用EntityBean这个方法必须包含.
看你的程序没有必要写成EntityBean,你不和数据库大交到.写成sessionBean好了．
你要靠这个找工作？自己学会有一定的难度．

[文艺青年2]

你是做在CabinHome类中的方法:
public Cabin findByPrimaryKey(CabinPK pk)
throws FinderException, RemoteException;
}
吗?
如果是,我定义了呀(如上所示);
如果不是,我看有关书籍,好象CabinBean中不需要定义ejbFindByPrimaryKey方法呀
