cmp存数据库一问

[try_okey]

看一个例子，数据库有表BnProject，对应字段有：InstanceNs、Parent、Name、Status、Creator、State、CreationDate、EndDate、BnProject_ID；对应CMP为BnProjectBean,但在程序里找不到有要插入最后一个字段BnProject_ID的代码，但操作完毕后BnProject_ID的值是有的，怎么回事？
相关的数据库操作代码如下：
public void setBnProjectValue( hero.interfaces.BnProjectValue valueHolder )
{

try
{
setInstanceNs( valueHolder.getInstanceNs() );
setParent( valueHolder.getParent() );
setName( valueHolder.getName() );
setStatus( valueHolder.getStatus() );
setType( valueHolder.getType() );
setCreator( valueHolder.getCreator() );
setState( valueHolder.getState() );
setCreationDate( valueHolder.getCreationDate() );
setEndDate( valueHolder.getEndDate() );
...
}
...
}


public BnProjectPK ejbCreate(String pName, String creator)
throws InvalidValueException, EJBException, CreateException {
log.debug("ejbCreate: pName=" + pName + " creator=" + creator);
BnProjectLocalHome projecthome;
BnProjectLocal project;

try {
projecthome = hero.interfaces.BnProjectUtil.getLocalHome();
} catch (javax.naming.NamingException be) {
throw new CreateException(be.getMessage());
}
try {
project = projecthome.findByName(pName);
throw new CreateException("BnProject " + pName + " already exist");
} catch (FinderException fe) {

try {
BServiceLocator serviceLocator = BServiceLocator.getInstance();
this.setId(BserviceLocator.generateUniqueId(BServiceLocator.PROJECT));

} catch (BServiceException e) {
throw new CreateException(e.getMessage());
}

// Each title must have a unique id to identify itself within the DB
//this.setId(generateUniqueId());

this.setName(pName);
this.setCreator(creator);
}

// This is only possible in CMPs. Otherwise return a valid PK.
return null;
}

this.setId(BserviceLocator.generateUniqueId(BServiceLocator.PROJECT));

应该是这句吧.

哦，漏写了，表字段里还有个ID字段，所以this.setId(BserviceLocator.generateUniqueId(BServiceLocator.PROJECT));应该对应的是ID这个字段，而不是BnProject_ID字段，这个字段不知是哪里插入值？

[try_okey]

另外，表里的字段如上所述为：ID、InstanceNs、Parent、Name、Status、Creator、State、CreationDate、EndDate、Type、BnProject_ID，但我在home接口BnProjectLocalHome里怎么还看到有public abstract void setModel( BnProjectLocal pmodel);方法，而且该方法在商务bean（BnProjectBean）里也就一个抽象方法，其派生类BnProjectCMP里没有再实现，但sessionbean里却有mProject.setModel(mProject);调用，怎么回事？？
