I have read some articles, and followed those step, but wasn't successful.
I have WebCrawler.class and CrawlerException.class under same dir.
I created myManiFest and content the following lines
In the same dir, I created jar file by typing the following:
jar cmf myMiniFest dkim18.jar WebCrawler.class CrawlerException.class
and got dkim18.jar file, but when I excuted the jar file by typing
java -jar dkim18.jar
I have "NoClassDefFoundError"
What did I do wrong?
