最简单的一个字段entity bean发布错误，不知道为什么？

[vcshcn]

数据库表user，里面有一个字符串字段 name，name是主键
package cs1;
import javax.ejb.EJBLocalObject;

public interface User extends EJBLocalObject {
public String getName();
}
------------------------------------------
package cs1;
import javax.ejb.EntityContext;

public abstract class UserBean implements javax.ejb.EntityBean {
public abstract String getName();
public abstract void setName(String name);

public EntityContext ctx;

public String ejbCreate(String name) throws javax.ejb.CreateException {
setName(name);
return name;
}

public void setEntityContext(EntityContext ctx) {
this.ctx = ctx;
}
}
--------------------------------------------
package cs1;
import javax.ejb.EJBLocalHome;

public interface UserHome extends EJBLocalHome {

public User create(String name) throws javax.ejb.CreateException;

public User findByPrimaryKey(String primarykey) throws javax.ejb.FinderException;
}

我用j2sdkee1.3发布，test出现
