Oracle SQL Developer가 Java 오류를로드했습니다.

Question

Oracle SQL 개발자에게 Java 코드를로드하려고합니다. 자바로드에서, 내 하드 디스크 (NetBeans 대상 폴더에서)에서 Java 소스를 선택하고 아래 오류가 발생합니다. 어떤 도움이 필요합니까? 여기

는 코드입니다. 그것은 넷빈즈에서 잘 작동 내가 된 .java 파일 sqldeveloper의 왼쪽 창 자바 옵션을 사용하여 자바 클래스를로드하는 동안 나도 같은 문제가되었다

에 SQL Developer에서로드하려고 해요. 그러나 내가 아래 코드를 사용하여 자바를로드하려고 시도했을 때, 그것은 작동했습니다.

CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "JavaClassName" AS 
public class JavaClassName{ 
    public static String MyFunction(){ 
     .....do something...... 
     return "output"; 
    } 
    }
