Question

我正在使用Jaunt库处理Web scraper。我目前在linux终端上遇到运行时错误：

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.NoClassDefFoundError: com/jaunt/JauntException

跑步时

：

java -cp .:.classes/jaunt1.3.3.jar class_name

我的.jar文件的目录如下所示：

leo@blah:~/workspace/Java/classes$ ls -al
total 164
drwxrwxr-x 2 leo leo   4096 Sep 13 17:25 .
drwxrwxr-x 4 leo leo   4096 Sep 15 10:59 ..
-rw-rw-r-- 1 leo leo 157786 Sep 11 19:40 jaunt1.3.3.jar

我的classpath看起来像这样：

leo@blah:~/workspace/Java/classes$ echo $CLASSPATH
~/workspace/Java/classes:home/leo/workspace/Java/classes/:home/leo/workspace/Java/classes/jaunt1.3.3.jar

有人可以帮帮我吗？谢谢！

使用Jaunt Library时ClassNotFoundException和NoClassDefFoundError？
