详细说明：Java已是构成整个Oracle环境的一部分．Java访问Oracle9i有两种基本方法：JDBC和SQLJ．0racle为开发Java程序提供了4种JDBC驱动程序，其中两种针对客户端程序如Applets，Servlets，另外两种针对服务器端或服务器内部数据库中的Java存储过程等使用．SQLJ则是把SQL嵌入Java代码中的高级语言． 给出了一个使用Oracle JDBC Thin驱动程序的实例．-Java is already constitutes part of the Oracle environment. Java there are two basic ways to access Oracle9i: JDBC and SQLJ. 0racle provided for the development of Java programs 4 JDBC driver, including two for the client program, such as Applets, Servlets, the other two for the server-side or server within the database using Java stored procedures. SQLJ is the SQL embedded in Java code in the high-level language. Gives a use Oracle JDBC Thin driver instance.
