前两天在贵站上看了一教程,但用javac编译home接口的时侯,出现错误,请指点..我把weblogic.jar加到了classpath中了....

1.远程接口
package examples;
import javax.ejb.*;
import java.rmi.RemoteException;
public interface Product extends EJBObject {
public String getName() throws RemoteException;
public void setName(String name) throws RemoteException;
public String getDescription() throws RemoteException;
public void setDescription(String description) throws RemoteException;
public double getBasePrice() throws RemoteException;
public void setBasePrice(double price) throws RemoteException;
public String getProductID() throws RemoteException;
}
2.Home接口
package examples;
import javax.ejb.*;
import java.rmi.RemoteException;
import java.util.Collection;

public interface ProductHome extends EJBHome {
Product create(String productID, String name, String description, double basePrice) throws CreateException, RemoteException;
public Product findByPrimaryKey(String key) throws FinderException, RemoteException;
public Collection findByName(String name) throws FinderException, RemoteException;
public Collection findByDescription(String description) throws FinderException, RemoteException;
public Collection findByBasePrice(double basePrice) throws FinderException, RemoteException;
public Collection findExpensiveProducts(double minPrice) throws FinderException, RemoteException;
public Collection findCheapProducts(double maxPrice) throws FinderException, RemoteException;
public Collection findAllProducts() throws FinderException, RemoteException;
}

用 javac -d . ProductHome.java提示如下错误..
ProductHome.java:7: cannot resolve symbol
symbol : class Product
location: interface examples.ProductHome
Product create(String productID, String name, String description, double
basePrice) throws CreateException, RemoteException;
^
ProductHome.java:8: cannot resolve symbol
symbol : class Product
location: interface examples.ProductHome
public Product findByPrimaryKey(String key) throws FinderException, Remo
teException;
^
2 errors
我用javac -classpath c:\1\src\examples ProductHome.java其中c:\1\src\examples是远程接口的class目录...出现更多的错误.....
