Java Jena SDB ClassNotFoundException

我是Jena SDB的新成员。我已经将SDB-1.2.3.jar包含在类路径中，并且数据库处于联机状态并使用此连接字符串。但是程序在第一行就崩溃了。请帮助我，也给我一些关于SDB Jena的有用的教程链接。我已经在他们的官方网站上试过了。 我的代码来自“站点”http://jena.apache.org/documentation/sdb/javaapi.html"

但是编译器给了我以下异常

arq jar文件不在类路径上。它应该与jena一起分发，所以请尝试查找lib目录。

它也会给我以下异常“线程中的异常”main“java.lang.NoClassDefFoundError:com/hp/hpl/jena/update/GraphStore”
