初学j2ee的人都会遇到这样的问题，您是如何解决的呢？

　　 
　　//本地接口
package securitybeans;
import java.rmi.RemoteException;
import javax.ejb.EJBHome;
import javax.ejb.CreateException;
public interface SecurityHome extends EJBHome{

Security create() throws CreateException, RemoteException;
}
编译后出的错误信息如下：
SecurityHome.java:6cannot resolve symbol
symbol :class Security
location : interface securitybeans.SecurityHome
Security create()throws CreateException, RomoteException;
^
1 error
//Security是远程接口，已编译生成了Security.class文件，并和Security.java在同一目录下
Security.java源代码如下：
package securitybeans;
import java.rmi.RemoteException;
import javax.ejb.EJBObject;
public interface Security extends EJBObject{
public String encrypt( String strSource ) throws RemoteException;
public String decrypt( String strTarget ) throws RemoteException;
}
//我该如何解决此问题
